Why is my waist so cold?

The temperature is low in the cold season, and the body has to dissipate a lot of heat through radiation, conduction and evaporation on the skin surface. I am 48 years old. My body does not produce enough heat, so my body feels very cold. My waist lacks twisting in winter. Because of the cold weather, I also lack movement. As a result, the area above the buttocks is in a "lazy state" and is prone to feel changes in temperature. It's like curling up in bed, always feeling cold! because. The main reasons for being afraid of cold are: 1. The basal metabolism of children is 10-15% lower than that of young adults, resulting in insufficient heat production. 2. Muscle activity is an important way to increase heat production. When people exercise strenuously, the heat production of muscles is 60 times the normal amount. Muscle atrophy, weight loss, and less activity, so the calories added by muscle activity are less. 3. Among the endocrine hormones, thyroxine, epinephrine and adrenocortical hormones can increase the metabolic rate and increase heat production. Due to the aging of the endocrine glands, the production of the above hormones decreases, so the heat production also decreases. 4. When it is cold, sympathetic nerves are excited and blood vessels contract, which will also reduce the heat dissipation of the skin. Due to the aging of blood vessels, slow response to cold and insensitivity of nerve regulation, the regulation of body temperature is affected, so that blood vessels cannot effectively contract when cold, thus fully reducing heat dissipation. In addition, some elderly people are thinner and have less subcutaneous fat, which is also one of the reasons for being afraid of cold. My suggestion is that 48 is an old age, and scalding your feet and wiping your body every day is a good way to keep warm, and you can also walk more (provided you wear warm clothes).

Thank you for accepting!
