Top 5 causes of winter drowsiness and effective tips

Why do I feel like sleeping all the time in winter? Is this normal or should I be worried?

Morning. The alarm clock rings. Once, twice, three times… But I feel like getting up even less than yesterday. In the afternoon – a cup of coffee, then another, then again… And I still feel like sleeping. A familiar situation? This feeling is especially strong in winter. Why does this happen? Is it just a seasonal feature or something more serious? Let’s figure it out – a list of the Top 5 causes of winter drowsiness and effective tips.

Darkness, cold and the biological clock: why a winter morning is a challenge

Waking up in the summer is easy. The sun is already shining through the window. The light awakens the brain , and even after a short sleep you can feel more or less alert. And in the winter? Darkness, grayness, even at eight in the morning it is almost night outside the window. The body perceives this as a signal: “still sleep.”

Our internal biological clock works depending on light. When there is little light, the body continues to produce melatonin, the sleep hormone. That’s why it’s so hard to tear your head off the pillow in the winter.

Melatonin, serotonin and their winter “conspiratorial” influence

It would be fine if melatonin worked alone. But in winter, the level of serotonin, the hormone of good mood and energy, drops. And where does it come from if there is almost no sunlight. Which stimulates its production?

Low serotonin isn’t just about sleepiness. It’s also about fatigue, reluctance to do anything, irritability. In other words, classic winter apathy.

Why the constant desire to sleep is not always about rest

It would seem that if you want to sleep, you should sleep more. But here’s the paradox: many people notice that even after 9-10 hours in bed, they are still exhausted. What’s the problem?

Lack of fresh air and movement: why do you want to sleep more in winter?

Winter is when you feel like going outside less and less, and sleeping more and more. Why is that? It’s not just about the darkness and cold. A sedentary lifestyle and lack of fresh air also play an important role in the feeling of constant fatigue.

Less walking means more sleepiness. In the summer, we move more: we walk, ride a bike, and take walks in the evenings. In the winter, everything is the opposite – maximum time in a warm room, and only the most necessary routes outside: “home – work – shop – home.”

What is happening to the body at this time?

🔹 Less oxygen – less energy
When we are in a closed space for a long time, the air becomes saturated with carbon dioxide. The less oxygen, the slower the brain works . The result is lethargy, decreased concentration, and the desire to lie down and fall asleep.

🔹 Blood circulation slows down.
Movement helps maintain normal blood circulation, which is important for delivering oxygen to all organs. Without it, you feel tired even after a normal working day.

🔹 Hormones also “fall asleep”
Physical activity stimulates the production of dopamine and endorphins – hormones of joy and energy. If there is little movement, the level of these hormones also decreases, which further intensifies winter apathy.

How the cold forces the body to work in “economy mode”

The lower the temperature, the more energy it takes to stay warm. But the body is not always willing to waste resources – sometimes it chooses another path: economy .

🔸 Metabolism decreases
In winter, metabolism slows down to preserve energy reserves longer. This is one of the reasons why we become less active and feel constantly sleepy.

🔸 Muscles work less
When it’s cold, we instinctively move less – as if we “coil over” to keep warm. But because of this, the body receives even less activity, which increases overall lethargy.

🔸 The body prepares for “winter hibernation”
Evolutionarily, humans have adapted to the fact that winter is a time when we need to spend less energy than in summer. That is why it is so difficult to wake up in winter and so easy to stay still.

What to do?

• Walk for at least 15-20 minutes every day – even a short walk in the cold activates blood circulation and saturates the body with oxygen.
• Ventilate the room – fresh air helps reduce carbon dioxide levels and increases concentration.
• Move more – even if you don’t go for a run, you can do simple exercises at home to “wake up” your body.

Winter is no reason to turn into a sleepy animal that only eats and sleeps. A little more movement, a little more fresh air – and you will feel more energetic!

Food as a source of energy (or vice versa?)

Winter is not only a blanket, hot tea and an eternal desire to sleep. But also a strange appetite. For some reason, your hands reach for hearty, high-calorie dishes, and without sweets it seems impossible to work. Is this just a seasonal whim or a signal from your body?

Why do you crave heavy food in winter?

Here’s an interesting detail: in winter, the body subconsciously switches to “heat preservation mode.” And what does this require? More energy! That’s why we start reaching for foods high in fats and carbohydrates – they take longer to digest and create a feeling of satiety.

In addition, there is another nuance: food affects the level of serotonin – the very “happiness hormone”, which is produced worse in winter due to lack of sun . Carbohydrates, especially fast ones (i.e. sweets, pastries), give a rapid increase in serotonin, which is why we really want to eat something “tasty” on a gloomy day.

But there is also a downside: the more such food, the more apathy and lethargy. A large portion of heavy food forces the body to direct all its resources to digestion, so after a hearty lunch you want to lie down instead of working.

Coffee, sweets and energy swings

And now about the most insidious winter “life hack” – endless cups of coffee and chocolates instead of a normal meal.

Caffeine really quickly “turns on” the brain, blocking fatigue receptors. But the effect is short-lived – after a couple of hours, energy drops even lower, forcing you to drink even more coffee. As a result, the nervous system is exhausted, and fatigue only accumulates.

The same goes for sweets. Sugar spikes blood glucose levels, giving you a short burst of energy. But then the levels drop – and fatigue returns even stronger.

How to avoid falling into “food hibernation”?

– Instead of heavy lunches – more protein and fiber (fish, eggs, legumes, vegetables).
– It is better to replace fast carbohydrates with slow ones (nuts, whole grains).
– Don’t rely on coffee – it is better to drink more water or herbal tea.
– Small meals help maintain a stable energy level without sudden spikes.

Lack of light
Even indoors in winter it is darker than necessary for normal brain function. What if you spend the whole day under artificial lighting? Energy decline is guaranteed.

Is it possible to outsmart the body?

If you’re constantly feeling sleepy in the winter , and you only have enough energy to pour yourself another cup of coffee, a logical question arises: is it possible to somehow “hack the system” and make yourself feel more energetic? The good news is that you can. The bad news is that it takes a little effort.

Actionable Tips: Working Ways to Fight Winter Lethargy

🟡 Morning light is the best alarm clock.
If in summer the body wakes up with the sun, then in winter it simply does not receive this signal. Therefore, it is important to “mimic” it – immediately after waking up, turn on bright light or use special daylight lamps. This will give the brain a signal: “The day has begun!”

🟡 Movement is not an enemy, but an ally.
Yes, you want to wrap yourself in a blanket and minimize any activity. But it is the lack of movement that leads to even greater fatigue. Even a 10-minute workout in the morning or an active walk in the afternoon can change the situation – blood begins to circulate faster, the brain receives more oxygen, and drowsiness recedes.

🟡 A proper breakfast instead of a coffee ritual.

Coffee without food is not the best idea. It gives a short-term boost, but without a full breakfast, your energy level drops quickly. It is better to choose foods that provide the body with “fuel” for a long time – proteins, healthy fats, slow carbohydrates. For example, eggs with avocado, Greek yogurt with nuts or oatmeal with chia seeds.

🟡 Cold water is an unexpectedly effective method.
No, you don’t have to pour ice water over yourself. Although this is also an option for the brave. It’s enough to simply wash yourself with cold water or even dip your hands in cool water for a few seconds – this will activate the nervous system and invigorate you.

Will artificial light and a proper daily routine help?

🔹 Artificial light really works. Daylight lamps, special “light alarm clocks” that simulate sunrise, help the body adapt to the short winter day. It is especially important to get bright light in the morning.

🔹 Daily routine is a key factor. The worst thing you can do in winter is to mess up your sleep schedule by staying up until 2am. And then trying to catch up on sleep on the weekends. The best option is to go to bed and get up at the same time, even if it’s dark outside.

So – is this normal?

Yes, it is absolutely natural to want to sleep in winter. The body works in “economy mode”, trying to preserve energy. But if drowsiness turns into chronic fatigue, even after rest there is no strength. And the mood is constantly at zero, it is worth paying attention to your lifestyle. And, perhaps, it is time to check the level of vitamin D. It has a strong effect on energy in winter.

For now, open the curtains, do a little warm-up, and don’t worry. There’s not much time left until spring.
