How does the human body regulate body temperature? Yao Qinghui posted on her Facebook fan page “Hui Girl Nutritionist” that the human body relies on the temperature regulation center of the hypothalamus to maintain a constant body temperature. Mainly through the four major heat transfer methods, including conduction, convection, radiation and evaporation, the combination of skin, pores, blood vessels and breathing determines how to regulate body temperature.

Yao Qinghui explained that when the temperature of the external environment is higher than the internal temperature, the body’s heat dissipation effect through conduction and radiation will become poor. If the humidity is too high, it will not be conducive to sweat evaporation and convection heat dissipation, which means that every heat dissipation path will not work. , may cause thermal injury.
Yao Qinghui emphasized that the current temperature is merciless, and it often jumps up to 30 degrees every day. In this case, heat injury is common. Excessive sweating often leads to electrolyte imbalance, and muscle spasms may occur; in order to dissipate heat, blood will rush to the skin, causing Heat dizziness due to low blood flow to the brain. In addition, what is commonly referred to as heatstroke is actually the most serious stage of heat damage. Usually, the core temperature of the body will soar and the skin will be dry and hot. If you want to avoid heat stroke, you must master the following 4 tricks:
1. Replenish water to avoid electrolyte imbalance: It is recommended to drink at least 2000-3000c.c. of water per day. If you are outdoors, it is recommended to add at least 500c.c. of water per hour, but please pay attention to drinking slowly in small sips; In addition, sports drinks can also be moderately consumed, but they cannot completely replace plain water. Also note that please choose low-osmotic or isotonic sports drinks.

2. Reduce blood vessel pressure and reduce inflammation: citrulline, vitamin C, quercetin, etc. are usually found in fresh fruits and vegetables. Citrulline and quercetin are vasodilator factors that can reduce blood vessel pressure. Vitamin C also helps fight inflammation after heatstroke.
3. Pay attention to the nutritional status of the intestinal tract: In heat injury or heat stroke, the blood flow to the intestinal tract in the body will decrease, and the intestinal peristalsis will decrease at this time, which may cause damage to the intestinal barrier. Because there are many immune cells and nerves in the gut, damage can trigger an immune or inflammatory response. It is recommended to eat light, moderate, digestible carbohydrates, or supplement probiotics at ordinary times.
4. Avoid going out from 10:00 am to 2:00 pm: this is the time when the sun is strongest during the day. In addition, please do not drink alcohol to replenish water, which may aggravate dehydration. Sugary drinks and eating ice are not recommended, because the body temperature is still high at this time, and encountering a large amount of cold food at once may affect blood circulation and intestinal function. , the heat is more difficult to discharge.
