Why is normal body temperature different from day to day?

A person's normal body temperature will change within a day. ..... In different time periods, people's body temperature will be different.

Specifically, the body temperature is different at different times of the day.

Specifically:

At about six o'clock in the morning, the body temperature is the lowest.

At about two o'clock in the afternoon, the body temperature is the highest.

This state of body temperature corresponds to the state of human body.

Specifically, there is the following correspondence between them:

1, when we rest, our body temperature will drop.

When we are exercising, our body temperature will rise.

This explains a problem: our body temperature corresponds to our physical condition.

In addition, there is another correspondence between our body temperature and physical condition:

1, when our body temperature drops, we will be at rest.

When our body temperature rises, we are in a state of exercise.

This correspondence shows that the change of our body temperature is needed by the state of our body.

Therefore, the essence of our body temperature change is the result of our body's constant adjustment to adapt to different states.

It is precisely because of the above reasons that our body temperature will have different values at different times of the day.

It is precisely because our body has this ability to adjust that it will have the ability to adapt to various environments and let us survive and develop better.

It should be noted that although our body temperature will change constantly throughout the day, the specific change value is not too great. ..... The difference between the highest and lowest values of our daily body temperature shall not exceed 1.2 degrees Celsius.
