Here you'll hear my personal stories, guest interviews, and vulnerable shares from clients and students. Most people know me from Instagram where you can find me under at cycle seeds, or they have been a coaching client or student in one of my courses.

[00:00:52] Iris Josephina: I'm so grateful you're here. Let's dive into today's episode.

[00:00:56] Iris Josephina: Hey, and welcome to a new episode of the Inner Rhythms Podcast. It took me a minute to come back online and spend some time on my podcast. My personal private life has been extremely hectic, and I simply didn't have the capacity in any way, shape or form to create a lot of content. The good news is that in the midst of all this craziness, I got a kitten and he is sitting here next to me.

[00:01:35] Iris Josephina: You may hear him purr, his name is Bibo and he is the sweetest little one.

[00:01:41] Iris Josephina: And I'm just so happy he is in my life. And yeah, taking care of a little animal, just it brings me so much fulfillment And For today's episode, I wanna discuss a topic that actually made me really angry. Maybe you have noticed, especially if you are like in Europe or in every other country that practices daylight saving time and

[00:02:12] Iris Josephina: oh my God, it's such a mess. This whole practice, I have so much to say about it. So grab a cup of tea, sit down or go on a walk or do your workout and listen to everything that I have to say. And I'm gonna start off by saying daylight saving time is a massive biological stressor, and we are not loud enough about that.

[00:02:40] Iris Josephina: We are not critical enough about that, and I am gonna take a deep dive with you into circadian rhythm, hormones, metabolism, mood, and the menstrual cycle. So let's get started. So every year the conversation around this time is the same like people complain about being tired for a few days around daylight saving time.

[00:03:07] Iris Josephina: They joke about, you know, daylight saving time on social media at least that's what I've seen this year. People grab an extra coffee, maybe they feel a little off or a little foggy or a little bit more irritable than usual, and most people just like move on and don't really care about it, but what usually does not get talked about enough is what is actually happening inside the body during that transition window.

[00:03:39] Iris Josephina: Because when you stop looking at this as a cultural inconvenience and really start looking at it through the lens of physiology. The picture changes completely. And once you understand the science, you're like, what the actual F are we doing to our bodies? And it, you know, when you look at the actual research, daylight saving time, especially the spring transition that we're going through right now is not just annoying, it really is a population skill, circadian disruption.

[00:04:17] Iris Josephina: Event and the downstream health effects show up very clearly in research and numbers. And it is honestly beyond me that nobody is doing something about this. We see more heart attacks, more strokes, more fatal car accidents, more workplace injuries, sleep disruption, metabolic dysregulation, mood instability, and.

[00:04:46] Iris Josephina: In my view, a much deeper conversation, we're still not having enough is about the effects on hormone health, fertility and the menstrual cycle. Because the thing is, and you know, if you've done any of my courses, especially my course cyclical. You know that the body does not organize itself around the wall clock.

[00:05:11] Iris Josephina: Your body organizes itself around light and darkness, and daylight saving time asks millions of people to suddenly live against that reality that fact, that blueprint overnight. So today I wanna walk through the history of daylight saving time, why it is fundamentally unnatural from a biological perspective, what it does to circadian rhythm, what it does to melatonin, cortisol, serotonin, insulin sensitivity, cardiovascular health, and metabolic health, and why this absolutely belongs in the conversation around the menstrual cycle and fertility health too.

[00:05:58] Iris Josephina: So the first thing that I want to say is that daylight saving time was never, ever, ever created for health. It was introduced during World War I as an economic and industrial strategy. Basically, it was seen as a way to conserve energy and maximize daylight hours during the workday from. You know, this energy perspective, like there has been some research that actually shows just like half a percent of energy saving, which I think is crazy.

[00:06:35] Iris Josephina: Like why would you throw all of your biology to save like 50, like a half a percentage of energy output? Like what? So from the beginning it was about, you know, so-called efficiency. It was about output, it was about productivity, and technically it was about squeezing more usable labor and activity out of the day.

[00:06:59] Iris Josephina: And it was not created because anybody thought it was good for the nervous system. It was not because anybody thought it supported hormone health and it was not created because it made human biology more coherent with, which is in essence what we want when we look at health. Uh, We are looking for biological coherence, and this is not it.

[00:07:19] Iris Josephina: This is not it. Oh my God, this stuff makes me so angry. I'm just gonna try to contain my anger as I move through this episode because there is just too much. Whew. So. I think one of the core problems of modern life is that we keep taking systems designed for economics and industry, and then acting shocked when the body struggles inside of them.

[00:07:47] Iris Josephina: Daylight Saving Time is one of the clearest examples of that. It's a, let's say it's a social policy imposed onto biology with the desire to create more output, more consumerism, more labor out of people. There also has been some research that when we do daylight saving time. People go shopping more and go out of the door later to buy things.

[00:08:15] Iris Josephina: And you know, with all of this, I'm just starting to wonder like, are we really so brainwashed that we just blindly.

[00:08:29] Iris Josephina: You know, disrupt our biology for the sake of culture and social policy. Because the thing is, biology does not care what politicians, governments, office culture, social policy, decides that the clock should say, your cells simply still respond to light and darkness. They're, they're not really changing that.

[00:08:54] Iris Josephina: The, the environment does change and the environment is thrown off, so it throws up your biology. Let me explain to you why daylight saving time is biologically unnatural. and this is just my standpoint. Daylight saving time is unnatural. It's unnatural. Like not in some like dramatic woo woo vague way.

[00:09:17] Iris Josephina: No, it's, it's literal disruptive, physiologically wrong because if, if you boil it down to just plain biology, humans are biologically primed for brighter days, darker nights, morning light exposure, and evening darkness. To set all the body clocks, specifically our cosmetic nucleus, which is our mother clock in our brain, and all of the daughter clocks, which are the peripheral clocks in every single hormone, every single organ.

[00:09:54] Iris Josephina: And this contrast of light and darkness, it tells the brain what time it is, and it anchors our circadian rhythm. We are really designed to live in relationship with the rising and setting of the sun. And we are not primed or designed to live with a social clock that suddenly jumps forward by an hour and expects the entire endocrine nervous, metabolic, and cardiovascular system to just adapt instantly.

[00:10:25] Iris Josephina: That is not how the body works. Your circadian system is a light based timing system. It's not a watch based timing system. And when social time suddenly shifts, but our solar reality does not. Your body and your biology experiences that as a mismatch, and that mismatch is what we call circadian misalignment.

[00:10:50] Iris Josephina: Let me go over what the circadian rhythm is. Very briefly. If you wanna learn more about this, get on the wait list for my course cyclical, because I go very, very deep into. Everything that I'm talking about today and how you can support your body. So the circadian rhythm is basically your internal 24 hour timing system.

[00:11:12] Iris Josephina: It regulates sleep and wake timing hormone production. Uh. Appetite and digestion, body temperature, your alertness and focus, your immune function, your mood, your metabolism, and your reproductive signaling. At the center of the system is your CSN, what I like to call the mother clock your matic nucleus, and this mother clock is primary, primarily synchronized by light coming into your eyes.

[00:11:40] Iris Josephina: Morning light basically tells your brain, hello. The day has begun, and as light enters the eye, melatonin production is suppressed and cortisol begins to rise in a healthy morning rhythm. This is also known as the cortisol awakening response, and that morning cortisol rise is not inherently. Bad. Like people these days tend to see like, oh my God, cortisol's bad stress.

[00:12:05] Iris Josephina: No. Cortisol is literally what wakes you up in the morning, mobilizes energy in your body. It sharpens your alertness, and it really gets your physiology ready for the day. And then later in the evening, as light levels start to fall, your pineal gland begins producing melatonin, which helps prepare the body for sleep and nighttime repair.

[00:12:27] Iris Josephina: So I hope you're already seeing the problem. If we reduce morning light and increase evening light, we distort the signals that tell the body when to wake and when to sleep. And that is exactly what daylight saving time does. It fucks up the system and the, the spring shift is the real problem. So the one that we've just moved through, if you are in a country where, we have adopted daylight saving time. So when, when clocks move forward in spring, mornings literally become darker and evenings literally become lighter. And it sounds like this is like some small thing, but physiologically, oh my goodness, it's not small at all because the problem is not just that you quote unquote lose an hour.

[00:13:15] Iris Josephina: The real problem is that the timing of light exposure changes in the most disruptive way possible. You get less light when you need it the most in the morning, and more light when it is disruptive in the evening. This means melatonin release gets delayed, sleep onset gets pushed to a later time. Wake time is forced earlier by a social clock.

[00:13:42] Iris Josephina: The sunrise maybe happens way after, and cortisol timing becomes misaligned and the body is effectively asked to function before it's truly ready. Because we are light beings, and I don't mean this in a like a wooo way or a spiritual way, we are literally responding to light. This is why the spring shift is consistently associated with more harm than the autumn shift, because the autumn shift moves us onto standard time. it is more connected to our biological time and the spring shift creates a, what we can call social jet lag. And except, you know. An actual jet lag where you get on a plane and, and you know, you change time zones. This is a government mandated circadian disruption event that people are expected to absorb as though nothing happened.

[00:14:39] Iris Josephina: And to me, that is really cuckoo. I find it so crazy and I, I really want to, um. Discuss some research on this because, you know, people just brush it off like, oh, I'm just, you know, for a couple of days I'll feel a little bit bad, but the research is crazy. So some of the strongest evidence around daylight saving time concerns the cardiovascular system.

[00:15:11] Iris Josephina: There are some studies. One of them in particular found that there is a 24% increase in heart attacks on the Monday, immediately following, following the spring, daylight saving time shift. A 24% spike on that Monday. And other studies have included, data from Sweden, Finland, Germany, Croatia, Brazil, and Mexico, and they have found similar patterns.

[00:15:41] Iris Josephina: Researchers still see like a modest, but statistically significant increase in heart attacks after the spring transition. So even if different countries show slightly different effect sizes, the pattern is real enough that it keeps showing up across populations. And this is where people usually say, but ah, you know, it's, it's just one hour.

[00:16:03] Iris Josephina: This is exactly the point. The cardiovascular system is highly sensitive to sleep loss, autonomic stress, inflammatory signaling, blood pressure changes, and circadian disruption, and it does not take a giant insult to create a measurable risk, especially in a vulnerable population. So what happens when we create acute sleep deprivation and shifts in our body like that?

[00:16:30] Iris Josephina: So it can elevate sympathetic nervous system activity, it can increase inflammatory signaling, it can disrupt cortisol timing, it can raise blood pressure variability and just technically put more strain on the cardiovascular system. So when a whole population is suddenly asked to be so misaligned.

[00:16:55] Iris Josephina: It should not be surprising that we see like an uptick in cardiac events and it's biology. It's what happens. The same story appears with stroke. Research has found an increased stroke risk in the first days following the daylight saving time transition with one study showing around 8% increase in stroke risk during the first two days after the spring shift.

[00:17:20] Iris Josephina: And this hits people who have less physiological resilience the hardest. So people already immunocompromised people with cancer, older adults, and for some people this is a real physiological destabilization event. And I think we need to be much more cautious about this. Now let's talk about metabolism.

[00:17:49] Iris Josephina: This is also a topic that I believe doesn't get enough attention, so, uh. One of the most important things that people do not understand is how quickly compromised sleep can disrupt insulin sensitivity. Even one night, or one or two nights of restricted or poor sleep can measurably impair insulin sensitivity.

[00:18:13] Iris Josephina: That means that your cells become less responsive to insulin. Glucose regulation becomes less efficient, blood sugar becomes less stable, and the body needs to work harder to maintain this balance. And that is not like some extremely rare scenario. That's just what sleep disruption does, and daylight saving time does not only steal one hour on one night.

[00:18:36] Iris Josephina: The spring shift often creates several days of degraded sleep, quality of sleep, fragmentation to late sleep onset, and just persistent circadian strain. If we layer all of this on top of one another, what happens? Less sleep, lighter evenings, darker mornings delayed melatonin altered cortisol timing more fatigue.

[00:19:00] Iris Josephina: More cravings, worse recovery. People are operating on a more metabolically, dysregulated state. This is why during this transition window, people may often experience, and I'm going through that right now, like my cravings are through the roof. I have not had cravings in months. People experience more hunger.

[00:19:22] Iris Josephina: Worse cravings, more sugar or carb seeking lower energy, poor workout recovery, worse, blood sugar stability, more irritability. That's me also 'cause I'm angry about all of this. And more stress reactivity. And this matters even more in people who already struggle with metabolic health. So people who have insulin resistance.

[00:19:45] Iris Josephina: If you are in your luteal phase when this happens, when you're naturally more insulin resistant, it will hit you harder. People are pre-diabetic people with PCOS and obesity. And if we keep looking at this metabolic story, sleep does not just affect insulin. It also affects the hormonal systems that regulate hunger.

[00:20:08] Iris Josephina: Like the feeling of satisfaction after a meal and stress. So when, when your sleep is shortened or fragmented, leptin tends to go down and ghrelin tends to go up, which means that people often feel hungrier, less satisfied, more impulsive around food, and less metabolically stable overall. At the same time, cortisol is getting pushed around.

[00:20:34] Iris Josephina: So normally cortisol should rise in the morning in sync with light exposure and the wake process. But when people are forced to wake earlier, while mornings are still darker, that normal cortisol awakening response. Can become less aligned with actual behavior and clock time. So now you have a stress hormone rhythm that feels off an appetite hormone rhythm that feels off blood sugar regulation that feels off, and a body that is trying to function on less and worse sleep.

[00:21:03] Iris Josephina: So what do most people do? I actually had a conversation with a client about this as well. So people reach for more caffeine, they push through, they maybe drink alcohol in the evening to unwind. We see, you know, in just general society, that people stay inside all day. Don't go outside enough, which makes the cycle worse.

[00:21:22] Iris Josephina: And you know, daylight saving time can set off this whole cascade. We have circadian disruption, we have poor sleep, we have impaired insulin sensitivity, we have worse appetite regulation, more fatigue and stimulants that people. You know, ingest an even worse sleep. And that's why I do not think this should be minimized at all.

[00:21:46] Iris Josephina: If we then dive a little bit deeper into more hormone timing pieces, we can look at melatonin, serotonin, and cortisol again. So when we look at melatonin. Melatonin is released in response to darkness. It helps you to initiate your sleep, but it's not just a sleep hormone. It's really involved in repair, antioxidant protection, mitochondrial health, immune signaling, and reproductive physiology.

[00:22:13] Iris Josephina: So when daylight saving time gives us more light, later in the evening, melatonin release gets suppressed or delayed. So people do not just go to bed later because they chose to. Their biology is being told, I know it is still daytime, no time to sleep yet. That means that sleep onset can be harder. There is a later sleep timing.

[00:22:33] Iris Josephina: There is a poorer recovery and there is more circadian drift. If we then look at cortisol, cortisol is supposed to rise in the morning. Morning light is one of the strongest anchors for that rhythm, but during the spring shift, mornings are darker and wake time is earlier. So now you may have a blunted or poorly aligned cortisol rhythm, which can look like difficulty waking grogginess, feeling tired, but wired, having poor energy, having a sluggish mood.

[00:23:04] Iris Josephina: This was me yesterday and today, and then the second wind energy. Later in the day when you really don't want it, like at nine or 11:00 PM your body is like, Ooh, we have a lot of energy. Let's go. Let's stay up. But obviously this interrupts with your sleep. Last hormone that I wanna discuss here is serotonin.

[00:23:27] Iris Josephina: Serotonin is also part of this conversation because daylight exposure, plays a very important role in mood and daytime neurochemistry. And serotonin is actually a precursor to melatonin, which is your sleep hormone. So when people get less morning light and more evening light, this can contribute to both mood disruption and poor sleep regulation.

[00:23:53] Iris Josephina: This is why research has linked daylight saving time shifts, especially to spring one, to worsen mood outcomes, anxiety, depressive disorders, and emotional instability. So from a hormonal and neurochemical perspective, daylight savings time is not neutral at all. It's not just a small thing and it.

[00:24:14] Iris Josephina: Perturbs, the timing of melatonin, cortisol, serotonin related mood regulation, glucose handling, and insulin sensitivity. And that's a lot of physiological disruption for something people still joke about, like it's just a cute seasonal annoyance. Like it's not, it's really not that innocent. And then something that I found interesting.

[00:24:38] Iris Josephina: I wasn't really looking at this, but you know, I was doing my research and I found out that the effects of daylight saving time don't stay internally in the body. They also show up externally. 'cause apparently we see an increased fatal car accident, rate in the period following the spring shift.

[00:24:59] Iris Josephina: And we also see apparently increased workplace injuries. In essence, it makes sense because sleep deprivation impairs our reaction time. It impairs vigilance, it impairs decision making, it impairs motor coordination and attention. So when that is happening across an entire population at the same time, basically what this says is that roads and workplaces become less safe.

[00:25:27] Iris Josephina: And this is why some people keep calling this a population scale circadian disruption event, because apparently it doesn't just affect personal discomfort and comfort and, you know, biology, but apparently it also affects collective safety. That's a big thing. No. And then, we, we already spoke about, serotonin.

[00:25:54] Iris Josephina: And it shows that circadian misalignment also affects emotional regulation in quite a few ways. So in the days following the spring shift, studies have reported increased depressed symptoms, more mood disturbance, greater irritability, worsened anxiety. And in some cases there is concern around increased suicide risk, although that piece is more complex and should be handled carefully.

[00:26:23] Iris Josephina: There is some research that is like touching upon that. What I take out of this is that the sleep deprivation and circadian disruption makes people less emotionally resilient. And this fits what we know from broader sleep science. So when your cortisol timing is off, your sleep is fragmented. Your S serotonin melatonin rhythm is disrupted.

[00:26:50] Iris Josephina: And if you already are under modern life stress, your ability to regulate your mood and your emotions becomes less stable. So if someone already struggles with anxiety, depression, burnout, trauma, or nervous system dysregulation, this transition to daylight saving time can be a real trigger point because physiology is under more stress.

[00:27:14] Iris Josephina: And I personally, I have a ADHD. It messes with me so much because I had such a good rhythm and I love getting up early. I love getting up with the sunrise and having this feeling that I have an ocean of time. So the sunrise rising here around 6:00 AM and I feel like, wow, I have such an ocean of time before I need to start work at nine.

[00:27:38] Iris Josephina: I can do all these. Things I can do my journaling, I can go on a walk, I can go to the gym, can have my breakfast, but now all of a sudden there it's this hour later and the sun rises at seven and there is little like less time before it's 9:00 AM between the sunrise and 9:00 AM when I need to start, you know, the things that I need to do during the day.

[00:28:05] Iris Josephina: So it gives me so much anxiety. That I feel pressured and stressed because there is less time between sunrise and what I need to do during the day. And I think it's really messed up. And I would love to know from, you know, other people who have a ADHD or even autism, like how is this, how is this affecting you?

[00:28:30] Iris Josephina: 'cause it's definitely affecting me. I don't, I don't like it at all. I actually hate it. I hate how it feels in my body. I don't like feeling pressured. I do really, really, really well when I have a rhythm that is, you know, timed around light availability during the day. So I live from sunrise to sunset on, you know, standard time when it's more biologically appropriate.

[00:29:00] Iris Josephina: And now it just feels all messed up. And I would love to take this conversation into fertility and menstrual cycle health. Because I don't think this gets talked about nearly enough. So circadian rhythm disruption does not just stay in a sleep lane or metabolic health. It also moves downstream into reproductive physiology because the menstrual cycle is a very energy dependent timing, dependent rhythm.

[00:29:28] Iris Josephina: And every phase of our menstrual cycle requires precision, not only from our reproductive hormones, but also from our circadian hormones. You know, follicular phase requires energy and signaling for follicle growth and rising estrogen. Ovulation is a highly coordinated signaling event. Uh, the luteal phase events on progesterone production, which is deeply energy dependent on one of the most.

[00:29:52] Iris Josephina: Mitochondria dependent processes in female physiology. But your menstrual cycle is not just hormonal, it's also circadian, it's mitochondrial, it's metabolic, it's lighting formed, it's stress sensitive. So when our circadian rhythm is disrupted, the body may respond with irregular cycles, the late or disrupted ovulation, lower progesterone resilience, worsened PMS, poorer energy availability, more inflammation.

[00:30:20] Iris Josephina: More blood sugar instability and more stress signaling. And you know, we also have the insulin piece. So insulin is not just about blood sugar, it also affects ovarian function, androgen balance, and follicle development. And so when sleep disruption impairs insulin sensitivity, that can absolutely impact menstrual cycle health and fertility too.

[00:30:44] Iris Josephina: And it's. Especially relevant for people who have PCOS or irregular cycles, subclinical infertility, luteal phase issues, PMS, chronic stress, or just fragile metabolic health. So in my opinion, daylight saving time really belongs, uh, in the hormone health conversation as well because the body reads light as information and when timing.

[00:31:13] Iris Josephina: Information is distorted. Reproduction is one of the systems that become less stable in the body. And, how I see all of this is that people are being asked to live their lives against a clock. And the way that modern society has been built up already states this like we are under artificial light for way too many hours.

[00:31:35] Iris Josephina: We sit too much. We don't see the sunrise and the sunset. And what, what I, what I see is that the wall clock says something, but our body clock then goes like, yeah, but I wanna do this at another time. And it's a chronic timing mismatch. And we already know from shift work what happens when people live in, in, you know, chronic out of sync states with their biology.

[00:32:03] Iris Josephina: Shift workers have higher rates of obesity, diabe diabetes, coronary heart disease, cancer, mood disorders, reproductive issues, and on average and earlier death. And you know, I'm not saying that daylight saving time is identical to shift work, but I'm saying that it activates the same basic mechanism, which is circadian misalignment.

[00:32:25] Iris Josephina: And once you understand that part, it becomes very hard to just dismiss it as something harmless. And another important point here is that even if people agree that we should stop switching the clocks. It does not automatically mean that permanent daylight saving dime is the best solution. A lot of circadian researchers argue that standard time is actually better for health because it preserves more morning light.

[00:32:54] Iris Josephina: And morning light is the strongest anchor for the circadian system and you know, more evening light may feel more like socially convenient. Uh, it may feel nicer for like shopping or dinners or outdoor activities, but it does not mean it's better for the biology of sleep, metabolism, mood or hormone regulation.

[00:33:17] Iris Josephina: And you know, what feels fun economically or culturally is not always what best supports human physiology. And I think we should pay a lot more attention to that because we have a lot of health issues going on in our society these days that I feel could be positively impacted if we included circadian misalignment in our assessment of health issues.

[00:33:52] Iris Josephina: So my recommendation is to take this more seriously than our culture tells us to do. And, yeah, daylight saving time is a policy decision that was never ever built around human biology I want us to become more aware of that. It's a biological stressor and yeah, I don't wanna, you know,

[00:34:19] Iris Josephina: create fear around this, but I would love to create critical conversation about this because we accept so many things in our society. That are of, you know, an economic benefit, intention, or like productivity focused. And these things are not in essence bad, but I do feel we need to start asking questions when it starts affecting our biology, because our biology is everything.

[00:34:56] Iris Josephina: And if we have biology that responds to proper timing cues, we support our overall general health and we preserve our health on the long term. And I hope that this was disturbing and inspiring to you. I hope you learned something new today. If you are interested in learning more about, you know, circadian biology and you are seeing that we are inherently cyclical by design.
