2. 1 degree: Need equipment or instruments (such as crutches, wheelchairs, etc.).

3, 2 degrees: Need help, supervision and education from others.

4, 3 degrees: You need both help and equipment and instruments.

5, 4 degrees: completely unable to be independent and unable to participate in activities.

The body constantly produces heat and continuously loses heat to the circulating environment of plants, and the two are in a dynamic balance. The heat generation process and heat dissipation process of the body are affected by many factors and are constantly changing.

Both are like trays on both sides of a balance. Under the control of thermoregulation mechanism, when the human body is in a state of balance, the normal body temperature is maintained at 37℃. If the balance of heat production or heat dissipation is out of balance, the body temperature will rise or fall.

Extended data

1, neuromodulation: the basic way is reflection, which can be divided into unconditional reflection and conditioned reflection. Neuroregulation plays a leading role in human functional activities. Neuroregulation is rapid, accurate and short-lived.

2. Body fluid regulation: refers to a regulation way that some special chemicals in the body affect physiological functions through body fluid pathways. Body fluid regulation is relatively slow, persistent and diffuse.

3. Self-regulation: refers to the adaptive response of tissue cells to environmental stimuli independent of nerve or body fluid factors. The range and scope of self-regulation are small.
