Mistakes That Cause Heat Stroke: During the summer season, heat stroke becomes a serious health issue that can sometimes prove fatal. People often believe that heat stroke is caused solely by prolonged exposure to intense sunlight, but the reality is far more complex.
A lack of awareness and failure to take precautions can take a toll on the body during summer. It is important to understand that heat stroke can result not just from the sun, but also from several of our own poor habits. In this article, we will first outline the symptoms of heat stroke and then explain the specific causes behind it.

First, Know the Symptoms
Recognizing the symptoms of heat stroke immediately is crucial, as the condition can be life-threatening. Key signs include high fever, headache, dizziness, nausea or vomiting, hot and dry skin, cessation of sweating, rapid heartbeat, weakness, and feelings of confusion or irritability.
In severe cases, a person may lose consciousness, and their nervous system and organs can suffer serious damage. If any of these symptoms appear, immediately move the person to a cool place, give them water, try to cool their body down, and seek urgent medical attention.
Causes of Heat Stroke Beyond Sun Exposure
1. Dehydration
In summer, when the body loses excessive fluid through sweating and we do not drink enough water, dehydration occurs. This disrupts the body's temperature balance, potentially leading to issues like dizziness, weakness, and headaches. Prolonged dehydration significantly increases the risk of heat stroke.
2. Poor Dietary Choices
Consuming excessive amounts of spicy, fried, or heavy food increases internal body heat. Digesting such food requires more energy, which can raise body temperature and heighten the risk of heat stroke. It is safer to consume light and fresh food during the summer months.
3. Prolonged exposure to heat
Staying in direct sunlight or in a very hot, enclosed space for an extended period causes the body temperature to rise rapidly. If the body does not get a chance to cool down, it can lead to heat stroke, a condition that can sometimes be severe.
4. Wearing tight and synthetic clothing
Tight and synthetic clothes trap sweat instead of absorbing it. This prevents body heat from escaping, causing the body to overheat. Wearing loose-fitting cotton clothing is the best choice during summer.

5. Lack of rest and excessive exercise
Working continuously without rest or engaging in excessive exercise during hot weather can cause the body to overheat. A lack of adequate rest reduces the body's ability to tolerate heat, thereby increasing the risk of heat stroke.
