Body temperature is not fixed and can change with factors such as gender, age, day and night, exercise, and mental state, but such changes are often within the normal range. So, what is the normal body temperature for adults during summer? Below is a simple understanding and understanding of this issue, hoping that the following points will be helpful to everyone!

Normal body temperature in adults during summer

Normal adults have a stable body temperature regardless of summer or winter, with armpit temperature between 36-37℃. Human body temperature is controlled by the immune nervous center. If it is cold in winter, more melting point activities should be done to maintain stable body temperature. During the hot summer, the immune nervous center will produce more neural impulses for heat dissipation, and the body temperature can also be kept within a stable range. Therefore, whether in summer or winter, even if there is some fluctuation in body temperature, it should be within the normal range. Generally, body temperature is higher in the afternoon or after exercise than in the morning, and the body temperature of the elderly is slightly lower than that of infants and adolescents. However, regardless of how it fluctuates, it is all within the normal range.

Factors affecting body temperature in adults during summer

Gender factors

Generally, women have a slightly higher body temperature than men. Women’s body temperature slightly rises before menstruation and in the early stages of pregnancy, is lower during ovulation, and this fluctuation is mainly related to the estrogen metabolic cycle. Women also have higher body fat than men, which should be another reason.

Age factors

A baby’s body temperature is easily affected by external temperature changes. Due to the incomplete development of the nervous central system in newborns and the incomplete development of the sebaceous glands of the skin, the specific immune function is weak and prone to fluctuations. Children and adolescents have a high basal metabolic rate, so their body temperature can be slightly higher than that of adults. The elderly have a lower body temperature due to a low basal metabolic rate.

Day and night factors

The body temperature is at its lowest from 2 to 5 a.m. and at its highest from 5 to 7 p.m., with a change range of about 0.5 to 1℃. This regular diurnal fluctuation is due to the relatively regular changes in long-term habits such as activity, metabolism, and the circulatory system. For those who work at night, the regular fluctuation is a rise in body temperature at night and a drop during the day. [2]

Mental state and physical exercise

When the central nervous system is excited due to emotional excitement, and when muscles contract during physical exercise, the body temperature can slightly rise. In addition, changes in the average external temperature and meals can also cause fluctuations in body temperature.
