temperature and perspiration

Sweating in the human body can be divided into no sweat and effective sweat. When the temperature is low, that is, below 20 degrees, the person is at rest, through the breathing, the pores of the skin spread, the sweat is discharged from the body every hour, and the heat is released. This sweaty person does not feel it, so it is said to be incapable of sweating. When the temperature rises to 25 degrees to 30 degrees or more, the human body radiates 174 to 348 kilocalories per hour through radiation, convection, and no sweat, but it is still lower than the amount of heat generated and required to be emitted from the body. The sweat is discharged through the sweat glands throughout the body to dissipate heat in the form of evaporation. This kind of sweat is in a liquid state, and people can feel it, so it is called effective sweat. Therefore, sweating is an important function to regulate body temperature, keep it at a relatively stable level, and keep people in a more comfortable state, so as to maintain full energy and health. Basic Information Specialist classification: growth and development check classification: endocrine examination Applicable gender: whether men and women apply fasting: not fasting Tips: Do not eat overheated or too cold food before inspection, sweaters use dry hand towel to dry, taboo after intense exercise check. Normal value When the temperature in the body and outside increases, the skin microcirculation blood flow increases, the flow rate increases, the blood vessels expand, and the sweat increases to dissipate heat; on the contrary, the body heat is low, when the outside temperature is low, the skin blood flow is reduced, and the flow rate is slow. The blood vessels contract to prevent loss of heat from the skin. At normal room temperature, the skin temperature is maintained at around 37 ° C, no sweating. Clinical significance Abnormal results: Excessive sweating is not good for health. Excessive sweating can reduce the flow of blood circulation in the human body, and the circulation slows down, which causes the body's heat dissipation to decrease, resulting in an increase in body temperature. A lot of sweating can also cause the body's salt to be lost, and the cells are devastated by the lack of sodium. People who need to check: excessive sweating or no sweat, less sweat, abnormal sweating, special newborns should often check the temperature. High results may be diseases: hot sweat, compensatory hyperhidrosis, sweating, prejudice Taboo before the test: Do not eat food that is too hot or too cold before the test. The sweater should dry it with a dry towel and check the check after strenuous exercise. Requirements for inspection: Keep quiet during the examination, avoid sweating, avoid eating, and follow the doctor's instructions. Inspection process Sweating is a natural phenomenon of the human body: when the temperature is too high, it will sweat, sweat when the spirit is tense, sweat on the face when eating irritating food... but sweat or sweat when it is not necessary to sweat Too much sweat should be taken seriously. When using the thermometer, hold the thermometer a few times to make the mercury at the starting point. Not suitable for the crowd Generally no taboos. Adverse reactions and risks Generally not.
