The human body has a constant temperature of 37°C. This temperature will only change under special conditions. Internal temperature control is essential for the body to be able to harvest enough protein to survive. Thermoregulation will, therefore, make it possible to maintain the appropriate temperature by constantly balancing heat inputs and losses. Here are some tips to help your body cope with the cold and understand how the thermoregulatory mechanism works.
Which parts of the body need the most protection in extreme temperatures?
In order to protect our internal organs such as the brain, our body is ready for anything. Even if it means sacrificing our extremities, such as fingers and feet, whose blood flow will be less important. The skin when it is more irrigated – is much less insulating, which is why it is necessary to protect the brain first, and it is irrigated continuously. However, it is important not to forget to protect your hands and feet, called “critical areas.”In cold weather, these critical areas can reach temperatures well below normal and can cause significant heat loss and annoying sensations, such as numb fingers. If this happens when it is less than 0°C outside, this is called hypothermia. To avoid this situation, you can wear insulating gloves or our connected heated insoles, Warm Series V6, that will keep your shoes warm all day long thanks to the built-in thermostat. Learn more…
How to fight the cold with keeping your own clothes ?
The trick to getting better thermal insulation even when wearing your usual clothes is to lay several layers on top of each other, allowing air to circulate between them. Air has only a very low thermal conductivity, and therefore, the heat will last longer. Wearing a garment with a larger amount of air in the mesh will also provide much higher thermal insulation. So it’s time to take out the sweaters our grandmothers knitted ! And above all, opt for loose clothing that promotes air circulation and avoid tight clothing.
What is the ideal outfit ?
The ideal outfit would consist of three layers of clothing. The first layer must be able to wick away perspiration. In this case, there are light sweaters made of special materials. The second layer keeps the air warm around the body and, therefore, must be quite wide. The third layer must absolutely protect against water and wind while allowing perspiration to escape. It is, therefore, unnecessary to wear several layers of thick wool sweaters that will not allow perspiration or air to pass through.
Should I choose a particular diet ?
The body will only burn more calories during intense activity or when exposed to prolonged cold. If this is not the case then it is not necessary to eat more fatty food to maintain the internal temperature. If it is cold, you can simply have a balanced diet and eat hot meals to make sure the body has enough energy. In addition, it is essential to drink regularly because the mucous membranes dry out much more quickly in cold, dry air.
Why do we shiver when we are cold ?
Our bodies start shivering to defend themselves from the cold. Indeed, when the muscle fibers contract, it is the organism that seeks to produce more heat. Shivers are, however, a sign that the body is having difficulty regulating the internal temperature and, thus, uses thermoregulation. At this point, it means that it is time to go home to avoid the risk of injury because the muscles are weakened. Indeed, during thermoregulation, muscle power and endurance are reduced.
Why do fingers turn blue when it’s cold ?
The three layers of the skin act as a real protection against extreme outside temperatures. Indeed, they will store grease and become thermal insulators. When it is cold, the different layers react to each other and this causes various sensations, such as frozen feet or blue fingers. These areas are much more sensitive because they have almost no fat or muscle. It is, therefore, essential to protect them if you want to avoid these sensations. Women need to be even more careful because they have much more sensitive skin.
Now that you know everything about thermoregulation and how you can protect your body, you can finally enjoy your holiday in the mountains or on skis!
