Every winter sport and outdoor recreation strengthens the body’s resistance
Annual temperature changes vary around the world (although the North-Central European average is 40°C and above in summer and about -26°C and below in winter. The human organism has adapted to these changes. Blood vessels narrow when the air temperature drops (so releases less heat from the body).
In the brain, there is a center for regulating the heat release system that a person creates during work and rest. After some time, however, the vascular musculature becomes fatigued and the blood vessels dilate. The blood then stagnates instead of flowing through the blood vessels. In these cases, the fingers and toes turn blue and the nose and ears turn bluish (which is a sign of the onset of frostbite). The tissues then do not receive food and oxygen and die (due to reduction and stoppage of blood flow). An untrained person can withstand 4 hours at a temperature of -5.5°C, an hour and a half at a temperature of -22°C and only 25 minutes at a temperature of -32°C. A coma occurs when the body temperature drops to 27. The effect of low temperature is dangerous because a person falls asleep when cooling down and freezes during sleep.
Water cools the organism/body much faster (especially when the water temperature has dropped below 15 °C). Even without special equipment, a person cannot survive in such cold water for more than 4 hours.
Exposing the body for 3 to 5 minutes a day at a low temperature increases resistance to the cold. This happens because of the enzymes that enable the initiation of glucose and the rapid burning of glucose in the cells. This compensates for the lost heat. The body becomes more resistant to colds and flu if it is exposed to cold for just a few minutes a day.
Resistance is also achieved by pouring water over one hand for 3 minutes a day or by staying at room temperature for 5 minutes. The resistance gained in this way is lost after 7 days from the end of the exercises.
Parents and children should stay outdoors during the winter months
- The best activity for both children and adults is playing with snowballs. Gloves are necessary, but playing ignites and warming up the body. Gloves become redundant. Clumping without gloves strengthens the blood circulation in the hands. The child should have less clothes when running in the snow because he sweats quickly, and when taking a break/rest from jumping/running in the snow, the child should be dressed in warm clothes.
- It is a pleasure for both children and adults to “make angels” in the snow, i.e. literally lie down in the snow and make various pictures with the movements of arms and legs (waving through the snow in a lying position), leave your own mark in the snow. This is best done when it snows, but there are no paths through the snow yet, it is full snow. Snow is ideal for various antics. It is ideal for children because it softens the impact and falls. Throwing in various poses in the white snow is a real experience.
- Sledding is the favorite game on the white blanket. You can use a plastic slide, a wooden or metal sled, a nylon bag or a sack filled with straw that just flies along the track. Using a sack or plastic bag, daring children and adults proudly defy all modern sledding props. The only rule is that each child or adult must pull their own sled after successfully descending the snow slope. This strengthens the muscles of the shoulder and back girdle. Children acquire responsibility towards their own objects and sports equipment.
- Skiing can start at the age of a child as early as 2 years old. Skiing activates the work of the muscles and joints on the legs and the sense of balance. Skiing develops endurance and perseverance in children.
- Children from 5 years of age can use skates. By skating (as well as during dancing), flexibility is acquired, movements, balance and body posture are perfected. A skater should warm up his muscles by walking before skating – which is very important for this sport.
- Layered clothing is important when staying in the snow because there is air between the parts of the clothing (which additionally protects against the cold). A good choice is waterproof clothing, as body temperature melts the snow, which then soaks the clothing. Too much clothing should be avoided because sweating and moisture occur, which cools the body.
