It's extremely hot in summer. Don't think that only workers will suffer from high temperature exposure. Many white-collar workers who need to work in the field can't help but withstand the sun, becoming a high-risk group of summer heat stroke. Today, let's share the symptoms and solutions of heatstroke.
1. Symptoms of heat stroke
1. Threatened heatstroke
In the high temperature environment, headache, dizziness, thirst, sweating, limb weakness and acid, inattention, uncoordinated action, etc., and the body temperature is normal or slightly increased.
2. Mild heatstroke
In addition to the above symptoms, the body temperature is often above 38 ℃, accompanied by flushing, sweating, skin burning, or cold limbs, pale complexion, decreased blood pressure, and increased pulse.
3. Severe heatstroke
It includes heat spasm, heat failure and heat stroke.
Thermal spasm is a sudden onset of painful muscle spasm during or after activity, usually occurring in the muscles of the back of the lower limbs (gastrocnemius and Achilles tendon), and also in the abdomen. Muscle spasm may be associated with severe sodium deficiency (sweating and drinking hypotonic fluids) and hyperventilation. Heat spasm can also be an early manifestation of heat stroke.
Heat failure is caused by excessive loss of body fluid and body salt due to excessive sweating. It often occurs in people who work or exercise in hot environment without enough water, and also occurs in people who are not adapted to high temperature and humidity. Its signs are: sweating, extreme thirst, fatigue, headache, nausea and vomiting, high temperature, and obvious dehydration signs such as tachycardia, orthostatic hypotension or dizziness There was no obvious central nervous system injury. Heat failure can be the intermediary process of heat spasm and heat stroke. If the treatment is not timely, it can develop into heat stroke.
2. Three points of first aid for heatstroke
When you or others have symptoms of heatstroke, you should give first aid immediately.
1. First, quickly evacuate from the hot environment and choose a cool and ventilated place to rest;
2. Sober people can drink some cool and salty drinks;
3. In severe cases, sharp objects or fingernails can be used to quickly and forcefully press Renzhong (i.e., the midpoint of the lower nose and upper lip groove) and Hegu (i.e., the middle point between the thumb and index finger of the back of the hand) and Hegu Point (i.e., the middle point between the thumb and index finger of the back of the hand) and be hospitalized immediately.
3. Pay attention to prevent heatstroke
1. Replenish water
Generally, indoor workers drink 8 to 10 glasses of water (about 2-2, 5 liters) every day. If they want to stay outdoors for a long time, their body water will lose a lot with sweat, so they must drink 2 to 3 cups of water.
Tips: water supplement generally refers to boiled water, tea, soup, milk, natural fruit juice, etc. cold and hot drinks are OK, but not including drinks with added sugar; in addition, drinks containing caffeine and alcohol can not replenish body water, but can dehydrate the body, which is the opposite.
2. Leave high temperature
Avoid staying in the high temperature and uncovered environment for a long time, try to find some covered places, avoid being exposed to the sun, or return to the shady place for rest at regular intervals.
Tips: put a wet towel on the neck, arms and other parts of the body that are directly exposed to the sun to help cool the body; in addition, many people in the high temperature environment will ignore that the body temperature has risen to too high, or even ignore that the body has mild heat stroke symptoms, so they can not save themselves in time, resulting in severe heatstroke symptoms, so we must pay more attention to whether the body temperature has been overheated And whether there are heatstroke symptoms.
3. Acupoints for treating heatstroke
Main points: Renzhong, Shixuan, Baihui, Yintang, Su, Weizhong, shaochong, Zusanli, Quchi, Hegu, Neiguan Points: high body temperature plus Quze; limb fatigue plus Qihai and Guanyuan; chest tightness, nausea and Shenque and Zhongwan.
4. Heatstroke small method, big effect
Once someone heatstroke, it should be quickly transferred to a cool, ventilated place, filled with some cold water or salt water. Then you can take antipyretic drugs, such as Huoxiang Zhengqi water, Rendan Qianjin Xiaoshu pill, etc. If there is fainting, the phenomenon of collapse, should first use the thumb to press the human point in the middle or plain point. Renzhong acupoint is a first-aid acupoint. When coma, collapse, shock and carsickness occur, people are often pinched to treat patients.
