One hour less, more fatigue? 😴

Nov 4, 2025

By Coline Helmreich

Hello everyone,

Every year, we experience it without always understanding why: simply setting the clock back is enough to disrupt our bodies.

So, we'll explain what's happening in your body and how to fix it!

Our biological clock shifts 🌙

The body remains aligned with sunrise. By abruptly changing the time, we disrupt the production of melatonin (sleep hormone) and cortisol (wake-up hormone).

Result: we fall asleep later, wake up tired, and feel "out of sync."

💡 Good habit: expose yourself to natural light in the morning. A walk, breakfast by a window, or a light therapy lamp help resynchronize your circadian rhythm.

Sleep is less restorative 😴

Our body temperature and hormone secretion follow a precise cycle. The time change disrupts this internal rhythm, which affects the quality of deep sleep.

💡 Good habit: establish a calm routine in the evening (screens off, dim lighting, regular schedule). And allow yourself a few nights for your body to naturally readjust.

Energy and concentration drop 🧠

By disrupting sleep and perceived light, the brain produces less serotonin and dopamine, two key neurotransmitters for well-being and motivation.

💡 Good habit: get some fresh air, move a little every day, and take regular breaks throughout the day.

These micro-actions help your internal clock reset and regain a good level of concentration.

Stress and irritability increase 📈

Lack of light and fatigue stimulate cortisol secretion, which makes you more nervous and sensitive to emotional variations.

💡 Good habit: breathe deeply several times a day (3 big conscious breaths are enough) and get plenty of magnesium to calm the nervous system.

Our metabolism slows down 📉

Less light, less movement, more fatigue: all of this influences digestion, energy metabolism, and even immunity.

💡 Good habit: support your body with a complete nutritional foundation that helps you maintain internal balance despite the change in rhythm.

And it's a good thing! Our Onday formula, rich in natural B vitamins, magnesium, amino acids, and probiotics, helps stabilize energy and mood by supporting nervous function and neurotransmitter synthesis 💪
