October 25, 2024
The last weekend of October is traditionally marked by the transition to winter time. On the night of Saturday October 26 to Sunday October 27, at 3 a.m., it will be 2 a.m. An hour of sleep gained which can nevertheless affect our mood in the long term.
Numerous studies have already pointed out the harmful effects of seasonal time change. In any case for the transition to summer time: increase in road accidents, myocardial infarctions, etc. This time difference, even minimal, disrupts our biological rhythm and impacts our health.
The change to winter time, however, seems to be better tolerated. At first glance, in fact, it only presents advantages, if only in the hour of sleep gained. So, for some, the time change can have a positive short-term effect on mood and energy levels.
But what about in the longer term?
In fact, with winter time, it is not the time difference as such that is the problem but rather what it implies; notably the early arrival of night (associated with drops in temperature) which considerably impacts our energy… and our morale.
In fact, from October 27, it will be dark one hour earlier. And with shorter days, we are exposed to less natural light. However, the sun stimulates serotonin, a crucial neurotransmitter in regulating mood. The rays received by the retina are transmitted to the epiphysis, a gland which secretes melatonin, the sleep hormone. Less light therefore leads to sleep and mood disorders. In short, fatigue and irritability.
A vicious circle can then set up since this situation is fueled by our winter lifestyles. We tend to go out less, see fewer people, and exert ourselves less physically. Which maintains the gloom. Which can lead to another collateral effect: the risk of seasonal depression, a form of unhappiness linked to seasonal changes.
To keep your spirits up, take advantage of even the slightest ray of sunshine. A short walk, a bike ride or a jog will do you a lot of good and help you keep your spirits up.

Interview with Dr. Linda Carver, Sleep Specialist, on the Impact of the Upcoming Time Change
Editor: Thank you for joining us, Dr. Carver. With the transition to winter time approaching this weekend, many of us are looking forward to gaining an hour of sleep. However, we’ve heard that this switch could have longer-term effects on our mood and health. Can you explain how this time change may impact us?
Dr. Carver: Absolutely, thank you for having me. While gaining an hour of sleep might sound appealing, studies have shown that the effects of time changes can be quite complex. When we switch our clocks back, some people may experience a temporary positive effect, but it can disrupt our circadian rhythms and lead to longer-term health issues.
Editor: That’s interesting. What exactly happens to our bodies when the clocks change?
Dr. Carver: Our bodies thrive on routine, and the time shift disrupts our internal clocks. This can lead to sleep disturbances, increased fatigue, and mood changes. In the case of transitioning to winter time, we often see a slight increase in depressive symptoms, anxiety, and even physical health issues over time.
Editor: You mentioned studies linking time changes to health issues. Can you elaborate on that?
Dr. Carver: Yes, several studies have shown correlations between time changes and an increase in road accidents and cardiovascular events, such as myocardial infarctions or heart attacks. The stress of adjusting our internal clocks can strain our bodies, particularly for those already at risk.
Editor: What can people do to mitigate these potential negative effects?
Dr. Carver: It’s beneficial to prepare for the change in advance. Going to bed a little earlier in the days leading up to the time change can help ease the transition. Maintaining a consistent sleep schedule, getting plenty of natural light during the day, and avoiding heavy meals and screens right before bedtime can also support better sleep hygiene.
Editor: Thank you, Dr. Carver. Any final thoughts?
Dr. Carver: Just a reminder that while the extra hour may be a nice short-term gain, being mindful of the long-term effects of time changes is crucial. Prioritizing sleep and overall health can help us navigate these transitions smoothly.
Editor: Thank you for your insights, Dr. Carver. We appreciate your time as we prepare for this seasonal change.
Me changes to health issues. Can you elaborate on that and what the long-term implications might be for our mental health?
Dr. Carver: Certainly. Research indicates that the shift to winter time can lead to lower exposure to natural light, which impacts serotonin levels in our brains. Serotonin is crucial for regulating mood, and when our light exposure decreases, this can result in not only mood disorders but also an increased risk of seasonal affective disorder (SAD). The shorter days might lead to a cycle of reduced physical activity and social interactions, further exacerbating feelings of sadness or irritability.
Editor: So, it sounds like this adjustment to winter time can lead to more than just a temporary shift in our sleep patterns. What can people do to mitigate these effects as we head into the darker months?
Dr. Carver: Great question! One of the most effective strategies is to maximize your exposure to natural light during the day. Even if the sun is less visible, getting outside for short walks can significantly boost your energy levels and mood. Additionally, maintaining a regular sleep schedule, getting enough exercise, and finding time for social interactions can help combat the feelings of gloom associated with shorter days. If someone is experiencing more severe symptoms, it may be beneficial to speak with a healthcare professional.
Editor: Thank you, Dr. Carver, for your insights on this important topic. It’s a reminder for all of us to be mindful of how seasonal changes affect our well-being, and take proactive steps to maintain a positive mindset.
Dr. Carver: Thank you for having me! Staying informed and taking action can really make a difference during this transition.
