Winters are always categorized with frozen mud, icy winds, and musty parkas. It is also a dark-induced season characterized by a lot of rainfall, making a lot of people sad. Furthermore, it is always accompanied by cold temperatures. However, research shows that there are two categories of people who can tolerate cold temperatures; men and indigenous Arctic groups like the Siberians. Since many people live in these cold areas, they need to acclimate and adapt to these areas.
Adapting to cold climates
For many years, people living in cold climates have been evolving. For instance, some are stout with shorter limbs. It makes them have a small surface area compared with their body mass from which to lose heat. Research shows that people from these regions also tend to have more brown fat, which is capable of generating more heat.
Additionally, the body metabolic rate of people in polar areas is higher than those who live in lower altitudes. That is why those in extreme areas need more calories to keep feeling warm and stay alive when it is extremely cold. According to the survey, the Siberians’ body metabolic rates always increase even if the temperature drops due to their adaptations in the polar areas.
When the non-Siberian Russians found themselves in this climate, their metabolic rates were high, but it was not higher than that of the typical Siberians. However, with long exposures to winter climates, anyone can increase their capacity to acclimatize to cold.
The Siberian bodies generate high metabolisms by increasing the uptake of thyroid hormones. These hormones are released by the glands found in the neck. People without these adaptations for their survival to be comfortable in cold areas must not take synthetic thyroid hormone to replicate the effect. Taking synthetic thyroid hormones can bring confusion to the thyroid, hence hampering its normal functioning.
Why men are also likely to adapt to cold climates than women
The body’s metabolic rate also explains why men are expected to withstand winter cold better than women. According to a survey, women are too cold at work because the building’s temperature is always set to men’s higher metabolic rates. Men can also be comfortable at temperatures such as 6 degrees lower than women are.
Other ways to adapt to cold environments
Since everyone cannot have strong genes to withstand difficult situations, there are other behavioral adaptations. For instance, putting on warm and heavy clothing. Furthermore, face, nose, and ear coverings can also be used to withstand these harsh conditions.
Other psychological adaptations can also help you settle in these areas; for example, one will acclimatize in the area after being exposed continuously for ten days. As you continue acclimatizing, your body becomes more effective in delivering warm blood to the entire body. This will eventually make you more resistant to cold as time goes by.
