Between the body which fights to regulate its temperature and certain viruses which enjoy the autumn season, it is advisable, to avoid falling ill, to take care of your diet, your sleep, your physical activity or even the famous barrier gestures.

Autumn is coming back to school. Even if it remains generally mild at the moment, we are faced with the usual temperature variations from morning to evening, or from one day to the next. And consequently, to the colds, headaches and fatigue that accompany them.

In fact, these temperature differences complicate the regulation of our body, which is responsible for maintaining a temperature of around 37°C. This effort tires the body and thus makes it more vulnerable to viruses.

Some viruses particularly like these variations which allow them to thrive, explains Benjamin Kaplan, a doctor at Orlando Health, Florida, to the scientific information site Live Science.

“Numerous studies show that the rhinovirus and the coronavirus are the two main agents of the common cold. However, they take advantage of milder temperatures to thrive as in spring or autumn,” he explains.

Conversely, the flu virus prefers cold, dry weather. A winter aficionado then.

Have a balanced diet

To avoid getting sick, it is advisable to maintain a healthy lifestyle. It is important to maintain a balanced diet that provides all the necessary nutrients. While avoiding eating fatter or in larger quantities because cooler temperatures do not involve a greater expenditure of calories.

“It is advisable to consume honey, known for its antibacterial properties,” explains the Paris Health Insurance on its site. Or vitamins and probiotics contained in dairy products, fermented vegetables such as pickles or olives or even sauerkraut. On the other hand, we must hunt down sugars which “annihilate immune functions”, underlines Doctor Christian Recchia on RMC.

“Sugar causes insulin secretions, insulin causes disturbances in immune functions,” he explains.

Get a good night’s sleep

Getting a good night’s sleep will be an asset in protecting yourself from germs. “Sleep is remarkably restorative for immunity. It is essential. You need to sleep 7 or 8 hours. Some can be satisfied with a little less but above all you need to feel that you get up rested,” says Christian Recchia.

Sports activity helps improve blood circulation and “helps with the self-cleaning of the respiratory tract”, assures Health Insurance.

Ventilate living spaces

It is also essential to renew the air in your home every day for at least 10 minutes.

“At home, we bring in all the ‘junk’ from outside, bacteria and viruses,” emphasizes Alexandra Chopard, doctor of pharmacy at Madame Figaro.

She adds: “You also have to think regarding ventilating your work space because you spend a lot of time there.” You must be careful not to overheat your home by maintaining an indoor temperature at 19 degrees.

In terms of clothing, it is advisable to adopt the onion technique, i.e. to favor layers of fabric, easily removable to be able to adapt to the temperature in all circumstances.

Then, there remain the essential barrier gestures. Actions that we know only too well since the Covid-19 pandemic, namely washing your hands regularly, drying them well or even covering your mouth with your elbow if you cough or sneeze.
