It is not a myth: the cold weakens our defenses. When the temperature falls suddenly, the body undergoes stress. In terms of nose, the first line of defense against viruses, vibratile eyelashes – these invisible little guards – become lazy. Result: the respiratory viruses, they are having a great time.
Add to that our natural tendency to take refuge inside, in enclosed spaces, often not very ventilated, and you get a perfect cocktail to circulate the microbes. The more confined the air, the more suspension the viral particles remain. A lesson learned to the hard time during the Cavid pandemic, and which remains valid in 2025.
Strengthen your defenses starts on the plate
No need to rely on magic potions. It all starts with what you put on your plate. Refined sugar, in particular, is the number one public enemy. It weakens our immunity by artificially boosting our white blood cells, which end up being less effective. So, we avoid sodas, repeated pastries and ready -made dishes.
Conversely, heading for foods rich in minerals: fatty fish, crustaceans, seaweed … Even an nettle soup, why not? These foods literally feed your natural defenses. And if you have a passion for herbal teas, know that thyme is an excellent intersane companion. An infusion with a little honey, and your throat will tell you thank you.
Sleep early to resist better
We can never say it enough: sleep is your best doctor. Melatonin – sleep hormone – plays a key role in regeneration of the immune system. She works while you sleep, but only if you are in bed at the right hours. Between 10 p.m. and 7 a.m., this is where she is the most active. So yes, even if your favorite series begs you to stay awake, it is better to record it and sleep. You will look at it in better shape the next day.
Sport, even sweet, as a natural shield
When you shift, hard to want to put on your sneakers. And yet, moderate physical activity remains one of the pillars of a good immune system. No need to run a half-marathon: walking, cycling or even gardening, everything counts. This stimulates blood circulation, makes toxins sweat, and gives body the resilience it needs.
But be careful not to play sports late at night. Adrenaline rises, and sleep descends. Ideal? During the day or early evening, for a winning combo.
Taken up … Really
Yes, it’s cold outside. But no, this is not a reason to live in an airtight box. Indoor air is often more polluted than outside air, especially when you stay there for several hours. A simple gesture can change everything: open the windows for ten minutes in the morning and in the evening. Even in the middle of chilly May, your health wins.
At the office too, it’s important. Between enrolled colleagues and computers that turn at full speed, air quickly becomes saturated. It is also to offer a little respite to your mucous membranes.
The temptation is great to go out wrapped up to the ears. But too much covering is also to prevent your body from adapting. You just have to protect the ends – head, hands, feet – and intelligently overlap your clothes to adjust them over the day. And at home? 19 ° C in the living room, 18 ° C in the bedroom. No need for a sauna to stay in shape.
