The summer is hot, so be careful to prevent heatstroke and keep cool

1. The impact of hot weather on the body

In a high temperature environment, the human body's temperature regulation mechanism may be disrupted, resulting in many adverse effects on the body.

1. Cardiovascular system: High temperature will cause blood vessels to dilate, heart rate to increase, heart burden to increase, and easily cause cardiovascular disease.

2. Nervous system: Symptoms such as dizziness, headache, inattention, fatigue, and irritability may occur.

3. Digestive system: High temperature will inhibit the activity of digestive enzymes, leading to loss of appetite, indigestion, and even symptoms such as nausea, vomiting, and diarrhea.

4. Urinary system: Excessive sweating can cause urine to become concentrated, increasing the risk of urinary stones.

2. Symptoms of heat stroke

Heatstroke is divided into pre-heatstroke, mild heatstroke and severe heatstroke.

1. Premonitory heat stroke: headache, dizziness, thirst, sweating, weakness and soreness of limbs, lack of concentration, uncoordinated movements, etc. in a high temperature environment. Body temperature is normal or slightly elevated.

2. Mild heatstroke: In addition to the above symptoms, the body temperature is often above 38°C, accompanied by flushed face, heavy sweating, burning skin, or cold limbs, pale face, decreased blood pressure, and increased pulse.

3. Severe heatstroke: including heat cramps, heat exhaustion and heat stroke. Heat cramps are characterized by muscle cramps and obvious pain; heat exhaustion is characterized by excessive sweating, cold and clammy skin, nausea, vomiting, dizziness, rapid heartbeat, and decreased blood pressure; heat stroke is the most serious type of heatstroke, characterized by high fever (body temperature over 40°C), no sweating, impaired consciousness, and even coma.

3. Preventive measures for heat stroke

1. Avoid going out during high temperature periods: Try to avoid going out during the high temperature period from 10 am to 4 pm, especially the elderly, children, pregnant women and people with chronic diseases.

2. Take protective measures: Wear a wide-brimmed sun hat, sunglasses, apply sunscreen, and wear breathable, light clothing when going out.

3. Replenish water and electrolytes: Drink at least 2000 ml of water every day, and don’t wait until you are thirsty to drink water. When sweating a lot, you should drink light salt water or sports drinks to replenish the lost electrolytes.

4. Arrange work and rest properly: Avoid long hours of continuous work, especially heavy physical labor in high temperature and high humidity environments. Take a proper rest during work breaks and take a short rest in a cool and ventilated place.
5. Pay attention to your diet: eat more light and easily digestible foods, such as fresh vegetables and fruits, and less greasy and spicy foods.

6. Improve the living environment: Keep the room well ventilated. Use air conditioners, electric fans and other cooling equipment, but be careful to avoid temperatures that are too low.

4. How to choose the right clothes to keep your body cool

1. Material selection: Give priority to fabrics that are breathable, sweat-absorbent and quick-drying, such as cotton and linen. Avoid wearing non-breathable clothing such as chemical fiber and nylon.

2. Color selection: Light-colored clothes, such as white and light blue, can reflect sunlight better than dark-colored clothes and reduce heat absorption.

3. Style selection: Loose, light clothing facilitates air circulation and helps dissipate heat.

5. How to choose the right diet to keep your body cool

1. Eat more fruits and vegetables: such as watermelon, cucumber, bitter gourd, winter melon, tomato, etc. These foods are rich in water and vitamins, which help clear away heat and relieve summer heat.

2. Eat heat-clearing foods: Mung bean soup, chrysanthemum tea, lotus leaf porridge, etc. have the effect of clearing heat and reducing fire.

3. Eat protein in moderation: choose low-fat, high-protein foods such as fish, chicken, tofu, etc.

6. How to choose the right drink to keep your body cool

1. Boiled water: It is the most basic and important drink and should be replenished at any time.

2. Light salt water: After sweating a lot, drinking a moderate amount of light salt water can replenish the lost salt.

3. Mung bean soup: has the effects of clearing away heat, detoxifying, relieving heat and quenching thirst.

4. Sour plum soup: sweet and sour, it tastes good, can stimulate appetite, help digestion, relieve heat and promote salivation.

5. Chrysanthemum tea: has the effects of clearing the liver, improving eyesight, clearing away heat and detoxifying.
