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℃.
Extended data:
36℃ is a health warning line.
In a day, the morning with the lowest body temperature is often the peak of death, and it is also easy for patients with asthma, insomnia and depression to wake up early at this time. High body temperature in the afternoon is also the best time for physical and mental health. The following mysteries of body temperature are particularly close to health.
36℃~ 37℃； The strongest immunity. Ishihara believes that normal body temperature means normal basal metabolic rate, and blood is full of fresh oxygen and nutrients, which can improve the function of white blood cells, help resist the invasion of viruses and bacteria, and enhance immunity. According to statistics, the body temperature drops 1℃, the basal metabolism drops by about 12%, and the immunity drops by about 30%.
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.
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.
