Normal body temperature is 36℃~37℃ (underarm). Dr. Tokushima Ishihara, a Japanese natural health expert, proposed a more precise range: the ideal body temperature is 36.5℃ ~ 36.8℃.

Body temperature fluctuates slightly within 24 hours, with the lowest at 2-6 am and the highest at 1~6 pm, and the fluctuation generally does not exceed 1℃.

The average body temperature of women is about 0.3℃ higher than that of men, and it will change with the change of menstrual cycle. Normal women's basal body temperature takes ovulation day as the dividing point, showing a state of low before and high after, also known as "biphasic body temperature".

Constant body temperature can make the human body live at different temperatures, but different people's body temperatures are slightly different. Children's body temperature is slightly higher, reaching 36.8℃ ~ 37℃; Babies and the elderly have lower body temperatures. Especially for premature infants, their body temperature is easily influenced by the environment because of the imperfect development of thermoregulation mechanism.

1, and the room temperature was maintained at 20℃. The average annual temperature in Bama, Guangxi is about 20℃, and it is also the hometown of longevity praised by the World Health Organization. The best sleeping room temperature is about 20℃. Above 24℃, the sleep becomes shallow, the times of turning over and kicking the quilt increase, and the room temperature drops below 18℃, making it difficult for people to sleep deeply.

3. Always walk at a brisk pace. The "big heat producer" of the human body is muscle, and the muscles of the lower limbs are very rich. Regular walking can exercise lower limb muscles, raise basal body temperature and make the body full of vitality.
