Introduction
Heatstroke may be caused by high ambient temperatures, certain occupations, hyperthyroidism, hypertension, diabetes, and other factors. It is recommended that patients drink plenty of water, eat easily digestible and light food, and consume more fresh vegetables and fruits appropriately when the weather is hot. If heatstroke occurs, prompt medical consultation and treatment at a hospital are necessary.
Heatstroke may be caused by factors such as high ambient temperature, certain occupations, hyperthyroidism, hypertension, and diabetes.
1. High Ambient Temperature
If the surrounding environment is hot and humid, especially in a sealed or poorly ventilated space, heat can accumulate in the body and fail to dissipate properly, leading to symptoms such as dizziness and fatigue. It's best to avoid going outdoors during peak heat hours, and maintaining adequate fluid intake can help preserve fluid balance.
2. Certain Occupations
Some jobs require strict protective clothing, such as chemical protection suits, fire-resistant gear, or radiation shielding garments. These clothes are often tightly sealed and poorly breathable. When working for extended periods in greenhouses, enclosed workshops, or vehicles, individuals are more prone to heatstroke. During work, seek shaded areas for cooling, or use fans or air conditioning to lower body temperature and prevent dehydration.
3. Hyperthyroidism
Excessive secretion of thyroid hormones increases the body's basal metabolic rate, resulting in greater internal heat production. In hot weather, this added thermal load can lead to symptoms like dizziness, headache, and limb weakness. It is recommended to take medications such as propylthiouracil tablets, methimazole tablets, or carbimazole tablets under medical guidance to suppress thyroid hormone production. Avoid prolonged exposure to high-temperature environments in daily life to help alleviate symptoms.
4. Hypertension
Hypertension can cause blood vessel walls to stiffen and narrow, impairing blood flow and the body’s ability to regulate temperature. In high temperatures, vasoconstriction may become more pronounced, making it harder for the body to dissipate heat, increasing the risk of heatstroke and dizziness. It is advisable to take antihypertensive medications such as amlodipine besylate tablets, felodipine sustained-release tablets, or levamlodipine besylate tablets as directed by a physician. Stay well hydrated when going outdoors and wear lightweight, breathable clothing to reduce the risk of heatstroke.
5. Diabetes
Unstable blood glucose control increases the body's energy demands under heat stress. This can disrupt fluid and electrolyte balance, raising the risk of heatstroke. Follow medical advice to take glucose-lowering medications such as glipizide sustained-release tablets, metformin sustained-release tablets, or glyburide tablets to manage blood sugar. Avoid going outside during hot weather to help reduce symptom severity.
In hot weather, individuals should drink plenty of water, eat light and easily digestible foods, and consume more fresh vegetables and fruits appropriately. If signs of heatstroke occur, prompt medical consultation and treatment are necessary.
