What will people eat in hot weather! Adverse reactions, such as nausea, vomiting and chest tightness! Or other adverse reactions! thank you

Hello! This friend, let me answer for you, I hope you can be satisfied! It seems that these symptoms are all symptoms of heatstroke: heatstroke refers to an acute disease characterized by disorder of central nervous system and circulatory system caused by disorder of body temperature regulation in high temperature environment. In addition to exposure to the hot sun, excessive work intensity, long time, lack of sleep and excessive fatigue are also common reasons.

According to the severity of clinical manifestations, heatstroke can be divided into threatened heatstroke, mild heatstroke and severe heatstroke, and the relationship among them is gradual.

Symptoms of threatened heatstroke

● In high temperature environment, symptoms such as headache, dizziness, thirst, hyperhidrosis, weakness and soreness of limbs, inattention and uncoordinated movements appear.

● Normal or slightly elevated body temperature.

● If you move to a cool and ventilated place in time and replenish water and salt, you can recover in a short time.

Mild heatstroke symptoms

● The body temperature is often above 38 degrees.

● In addition to dizziness and thirst, symptoms such as flushing, sweating and burning skin often appear, or cold limbs, pale face, decreased blood pressure and accelerated pulse.

● If handled in time, it can often be recovered within a few hours. Severe heatstroke symptoms, as the name implies, are the most serious heatstroke, and if not treated in time, it will be life-threatening.

This kind of heatstroke can be divided into four types: heat spasm, heat exhaustion, heatstroke and heatstroke.

Characteristics of symptoms of heat spasm: it mostly occurs when the concentration of sodium chloride in blood drops rapidly and obviously due to excessive sweating and thirst, excessive drinking water and insufficient salt supplementation. When this kind of heatstroke happens, the muscles will suddenly have paroxysmal spasmodic pain.

Symptoms and characteristics of heatstroke: this kind of heatstroke mostly occurs in the elderly and people who can't adapt to the high temperature for a while. The main symptoms are dizziness, headache, palpitation, thirst, nausea, vomiting, cold skin, decreased blood pressure, syncope or confusion. At this time, the body temperature is normal or slightly higher.

Symptoms and characteristics of heatstroke: The cause of this kind of heatstroke is just like its name, because under the direct irradiation of the scorching sun, strong sunlight penetrates the skin and skull of the head and causes brain cell damage, which in turn causes brain tissue congestion and edema; Because the main injury is the head, the initial discomfort is severe headache, nausea and vomiting, irritability, and then coma and convulsions may occur.

Symptoms and characteristics of heatstroke: Some people have been engaged in manual labor in a high temperature environment for a long time, and the body produces too much heat, but the heat dissipation is insufficient, resulting in a sharp rise in body temperature. At the beginning of the onset, a lot of cold sweat broke out, followed by no sweat, shallow breathing, rapid pulse, restlessness, confusion and decreased blood pressure, which gradually developed into coma with limb convulsions; Severe cases can produce brain edema, pulmonary edema, heart failure and so on.

Countermeasures:

What should I do after heatstroke?

When you find yourself and others with symptoms of threatened heatstroke and mild heatstroke, the first thing to do is to quickly evacuate the high temperature environment that causes heatstroke and choose a cool and ventilated place to rest; And drink more salty and cold drinks. You can also apply cool oil, wind oil essence, etc. On the forehead and temples, or take Ren Dan, ten drops of water, Huoxiang Zhengqi water and other traditional Chinese medicines. If your blood pressure drops and you collapse, you should lie flat immediately and go to the hospital for intravenous drip of normal saline in time. For severe heatstroke patients, in addition to immediately transferring them from high temperature environment to a cool and ventilated place, they should also be sent to the hospital quickly and take comprehensive measures for treatment.

Protection:

Travel to avoid the scorching sun

Remember to prepare sunscreen equipment when you go out in summer. 10- 16 It's best not to walk in the scorching sun, because the sun is strongest at this time, and the possibility of heatstroke is 10 times as usual! If you must go out at this time, you must take good protection, such as umbrella, sun hat and sunglasses, and it is best to apply sunscreen if possible; Prepare plenty of water and drinks. In addition, in the hot summer, you can take heatstroke prevention and cooling drugs, such as ten drops of water, Ren Dan, essential oil, etc. It must be kept at hand in case of emergency. When going out, try to choose cotton, linen and silk fabrics, and wear less chemical fiber clothing to avoid heat dissipation in time when sweating a lot, resulting in heatstroke.

The elderly, pregnant women, patients with chronic diseases, especially those with cardiovascular diseases, should try to reduce outdoor activities in the hot season.

Don't wait for thirst to drink water.

Don't wait for thirst to drink water, because thirst already shows that your body is short of water. Ideally, drink 1.5 to 2 liters of water every day according to the temperature. When sweating a lot, you can add some salt water appropriately to make up for the salt lost by sweating. In addition, the human body is prone to potassium deficiency in summer, which makes people feel tired and weak. Potassium tea is an excellent summer drink. Seasonal vegetables in summer, such as lettuce, cucumber and tomato, have high water content. Fresh fruits, such as peaches, apricots, watermelons and melons, have a water content of 80-90% and can be used to replenish water. In addition, dairy products can not only replenish water, but also meet the nutritional needs of the body.

get enough sleep

In summer, the days are long and the nights are short, the temperature is high, the human body has a strong metabolism, consumes a lot, and is prone to fatigue. Adequate sleep can relax the brain and body system, which is not only beneficial to work and study, but also a measure to prevent heatstroke. The best time to sleep is from 22: 00 to 23: 00, and the best time to get up is from 5: 30 to 6: 30. Be careful not to lie under the air conditioning outlet and electric fan when sleeping, so as not to get air conditioning disease and catch a cold.
