The tragic death of a 49-year-old man from a sudden brain hemorrhage has once again raised public concern about health risks during extreme heat. Despite appearing healthy and active, the man collapsed at home after engaging in a series of activities that, while seemingly harmless, became dangerous under scorching weather conditions. Doctors are now urging the public to take serious precautions, especially during summer months, to prevent similar incidents.

According to medical reports, the man had returned from a morning jog, a routine he had followed for years. However, that day, temperatures had soared past 38°C (100°F). After his jog, he immediately took a cold shower and consumed a large glass of iced water. Within minutes, he complained of a severe headache, dizziness, and nausea. He was rushed to the hospital, where doctors diagnosed him with a brain hemorrhage caused by a sudden spike and then drop in blood pressure, triggered by rapid cooling and dehydration. Despite emergency treatment, he passed away within hours.

This incident may sound rare, but doctors say such cases are becoming increasingly common in areas experiencing extreme heat. Dr. Suriwat Namsiri, a neurologist based in Bangkok, explains that "our bodies are under intense stress during heatwaves. The heart works harder to cool the body, blood vessels dilate, and if you're dehydrated or suddenly exposed to cold, it can cause blood pressure to fluctuate rapidly. This can result in strokes or hemorrhages."

So what are the activities that people should avoid when temperatures soar?

1. Sudden Cold Exposure After Heat

Jumping into a cold shower, pool, or blasting air conditioning right after being outside in extreme heat may feel refreshing, but it shocks the body. This can lead to vasoconstriction—blood vessels tightening rapidly—which increases the risk of a stroke or heart attack.

2. Intense Physical Exercise in the Heat

While exercise is generally beneficial, doing it outdoors under high temperatures can lead to heatstroke, dehydration, and increased blood viscosity. This makes it harder for the heart to pump blood and raises the risk of brain hemorrhage, especially in people over 40.

3. Skipping Hydration

Many people underestimate how much water the body loses through sweat during hot days. Drinking water only when you feel thirsty is not enough. Doctors recommend drinking small amounts regularly, avoiding alcohol and caffeine, which contribute to dehydration.

4. Taking a Nap Immediately After Being in the Sun

After being exposed to direct sunlight for long periods, going inside and lying down immediately can cause blood pressure to drop too quickly. Rest is important, but the body needs time to cool down gradually.

The man's death serves as a painful reminder that our bodies are not invincible, especially under environmental stress. While we cannot control the weather, we can control how we respond to it. Dr. Suriwat advises people to listen to their bodies, avoid extreme behavior, and prioritize hydration and gradual cooling during hot days.

In conclusion, heat may seem like just a seasonal inconvenience, but when combined with the wrong habits, it can become a silent killer. Let this tragic story be a wake-up call. During hot weather, stay safe, stay cool—but above all, be cautious. Life is precious, and prevention is often our best defense.
