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℃.

Different people have slightly different body temperatures. Children's body temperature is slightly higher, reaching 36.8℃ ~ 37℃; Babies and the elderly have lower body temperatures. 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. Anemic women's body temperature is 0.7℃ lower than that of women with normal hemoglobin, and their heat production is less 13%.

Extended data

36℃ is a health warning line.

1, below 36℃: danger signals appear in the body.

When the body temperature is lower than 36℃, the body will tremble to generate heat energy, accompanied by dark circles, red nose, purple complexion, palms and lips. Among modern women, due to factors such as increased pressure, lack of exercise, irregular sleep and diet, the number of patients with chills has increased. Hypothermia leads to poor blood circulation, abnormal white blood cells and decreased immunity. Diseases such as asthma, pneumonia and rheumatism will naturally come to you.

2, below 35℃: the most deadly to the elderly.

When the body temperature drops to 35℃, it is called hypothermia. Patients are consciously afraid of cold, their skin is cold, their limbs are cold, they are unwilling to get up, and it is difficult to walk. The elderly and malnourished people are most likely to appear. The elderly with hypothermia in autumn and winter account for about 10%. The elderly are prone to cardiac arrest when their body temperature is below 35℃ for more than 24 hours.

3. When the body temperature drops to 32℃, the chills disappear and drowsiness occurs; When the temperature drops to 28℃, ventricular fibrillation will occur, which will eventually lead to cardiac arrest; When the temperature drops to 25℃, the patient is in a coma, the reflex disappears, the pupil size varies, and the response to light is weak; When the temperature drops to 20℃, the heart will stop beating.
