In cold weather, foods containing simple sugars (sweet and flour products) are very quickly digested and instantly trigger the body’s metabolic processes. Complex carbohydrates (cereals, legumes, plant fibers), unlike simple ones, are absorbed more slowly, but also provide the body with energy for a longer time.
Actions and behavior in cold weather during an emergency, prevention of hypothermia.
Fats (butter, lard, meat) are of even greater energy value, but it should be borne in mind that they are digested and absorbed much more slowly than carbohydrates. When food is often taken in small portions, this creates a higher level of metabolism in the body, which in turn increases the amount of calories burned, which ultimately helps to generate more heat for a person.
Avoid tight clothing, shoes, and equipment..
Timely change from wet to dry clothes.
Make or find a shelter.
Try to isolate your body from cold surfaces..
Give up alcohol.
Drinking alcohol, especially in cold weather, impairs the ability of the liver to maintain blood sugar levels, forcing the consumption of glucose for the absorption of alcohol, this puts a person at risk of developing hyperthermia. Alcohol reduces the trembling reaction and allows a person to feel more comfortable in cold weather, while at the same time complicating and interfering with the natural processes of thermoregulation in the body.
In cold weather, be lazy and avoid overwork.
During work, a person produces energy, an increase in physical activity increases energy production, and almost 80-90% of this energy is heat. A small part of this heat is lost from the surface of the skin, and everything else is transferred into the body. However, if you work to the limit of your capabilities, then this will quickly lead to the burning of the glucose reserves available to your body and will force you to consume the reserves left in reserve. Using all available glucose and glycogen stores will lead to exhaustion and overwork of the body..
To prevent this, in cold weather, you should work no more than 50-60% of your capabilities. This will force the body to use its reserves of fat, instead of burning limited reserves of glycogen and glucose reserves. As a result, you can work longer or move on to the point where fatigue comes. In addition, intensive work in the cold will cause perspiration, sweat drops accumulating on the body and the inside of the clothes, reduce its heat-insulating properties and the body will undercool.
In cold weather, the easiest way to not freeze is to lock the heat inside with insulation in the form of clothes, adding or removing layers of it when changing external weather conditions. Plus physical exercises, a bonfire, protective shelter, hot drink and high-calorie foods. All this will help to maintain the average body temperature at the level necessary for life..
