As hot weather approaches, how to prevent heatstroke?

As global warming makes hot weather more common, it's important to know how to prevent heat stroke, a potentially fatal illness caused by prolonged exposure to high temperatures that prevent the body from effectively dissipating heat.

1. Causes of heat stroke:

Heat stroke is caused by an imbalance between the body's heat production and heat dissipation. In a hot environment, the human body dissipates heat through sweating, but when the ambient temperature is close to or exceeds body temperature, this heat dissipation mechanism will be affected, causing the body temperature to rise.

2. Symptoms of heat stroke

Premonitions of heat stroke : headache, dizziness, thirst, sweating, fatigue, and nausea.

Mild heatstroke : body temperature rises to above 38°C, face becomes flushed, and heartbeat increases.

Severe heat stroke : includes heat stroke and heat exhaustion, symptoms include high fever, dry skin, confusion, convulsions and even coma.

3. Scientific methods to prevent heat stroke

Dress appropriately : Choose lightweight, breathable clothing such as cotton or quick-drying materials.

Replenish water : In hot environments, you should drink water frequently to avoid dehydration.

Avoid hot periods : Try to avoid being outside during the hottest part of the day (usually the afternoon).

Shade measures : When engaging in outdoor activities, use shade tools such as parasols and hats.

Indoor cooling : Use air conditioners, fans and other equipment to lower the indoor temperature.

Dietary modifications : Eat light, water-rich foods such as fruits and vegetables.

Take adequate rest : When working or exercising in a hot environment, you should take appropriate breaks to avoid excessive fatigue.

Understand your personal health conditions : Certain health conditions, such as heart disease and obesity, may increase your risk of heat stroke.

4. Emergency treatment of heat stroke

Move to a cool place : Move the patient to a cool and ventilated place quickly.

To reduce body temperature : Spray the body with cool water or soak the patient in cool water.

Rehydration : If the patient is conscious, give a drink containing electrolytes.

Monitor symptoms : Closely observe the patient's symptom changes and call emergency services if necessary.

V. Protection of Special Populations

Children : Children’s ability to regulate body temperature is weaker, so special attention should be paid to their protection in high temperatures.

Elderly people : Elderly people may be less sensitive to high temperatures and may need extra attention from their family members.

Outdoor workers : Construction workers, farmers and other outdoor workers should take additional protective measures.

6. Application of technology in preventing heat stroke

Smart wearable devices : monitor body temperature and heart rate, and warn of potential heat stroke risks.

Environmental monitoring technology : Use weather stations and mobile phone apps to get real-time weather information.

In addition, specific preventive measures and emergency treatment methods should be adjusted according to individual health conditions and local climatic conditions. It is best to consult a medical professional before implementing any health-related advice.
