Scientists have explained why some people are constantly cold

With the onset of winter, many people begin to feel the cold almost constantly. However, some people are cold all the time, even in the warm season. Specialists from the British University of Lancaster explained why this happens.
The average normal body temperature is 36.6 ℃, but deviations up to 0.5 ℃ are not considered a violation. In addition, a person's body temperature can vary throughout the day, reaching a maximum around 6:00 p.m. and decreasing to a minimum around 4:00 a.m.
According to information, anatomical features play a big role in feeling cold. For example, men always generate more heat due to a higher percentage of muscle mass. Fat layers, which are distributed differently in men and women, play a significant role in this. In women, the layer of fat under the skin on the arms and legs is almost twice as thick, so it is harder for heat from other muscles to reach the temperature receptors in the skin.
In addition, the sensation of heat and cold is affected by hormones. In women, there is a cyclical change in the basic body temperature, which is affected by various sex hormones. And a higher level of testosterone in men can make you feel cold less.
Another reason for the constant feeling of cold is various diseases. For example, Raynaud's disease is a condition in which some parts of the body, especially the fingers and toes, become cold and numb in response to cold temperatures or stress. It is noted that women are more likely to suffer from Raynaud's disease, as are those who live in colder climates. Another disease that affects body temperature is hypothyroidism, which stops the production of enough thyroid hormones, which are necessary to maintain energy levels and internal temperature.
Also, the problem can lie in arteriosclerosis – a chronic disease of the walls of the arteries, which is characterized by their thickening, hardening and loss of elasticity, which leads to the deterioration of blood circulation. In addition, persistent or prolonged sensitivity to cold can cause frostbite, even after the visible injury has healed.
