Doctor explains Heatstroke (Sun Stroke) | Causes, Symptoms, Treatment

In this video, I delve into a critical health topic that can escalate quickly if not addressed: heat stroke. This condition, also known as sunstroke, is a medical emergency that occurs when your body overheats, reaching a core temperature of 104 degrees Fahrenheit (40 degrees Celsius) or higher. Understanding heat stroke is essential not only for your well-being but also for the safety of your loved ones, especially during the sweltering summer months.

Heat stroke is the most severe form of heat-related illness. Before it manifests, individuals may experience heat cramps or heat exhaustion, but heat stroke signifies a failure of the body’s temperature control system. If not treated promptly, it can lead to serious complications or even be life-threatening. So, what causes heat stroke? There are two primary types: classic (or non-exertional) heat stroke and exertional heat stroke. Classic heat stroke typically affects older adults or those with pre-existing health conditions, often occurring after prolonged exposure to high temperatures, especially during heat waves. On the other hand, exertional heat stroke usually affects younger, healthy individuals engaged in intense physical activity in hot weather—think athletes, outdoor workers, or military personnel.

Several factors can increase the risk of heat stroke. Wearing heavy clothing that traps heat, consuming alcohol, and failing to hydrate adequately can all contribute to overheating. It’s crucial to be aware of these risk factors, especially as temperatures rise.

Recognizing the symptoms of heat stroke is vital. Key signs include:

• A very high body temperature (104°F or 40°C or higher)
• Changes in mental state, such as confusion, irritability, or slurred speech
• Unusual sweating patterns—hot and dry skin in classic heat stroke, while exertional heat stroke may present with heavy sweating
• Flushed red skin
• Nausea or vomiting
• Rapid breathing and a racing heart rate
• A throbbing headache

These symptoms require immediate medical attention. While not all may indicate heat stroke, they should be evaluated by a healthcare professional. It’s also important to note that skin changes may not be as apparent in individuals with darker skin tones.

If you suspect someone is experiencing heat stroke, don’t hesitate—call emergency services right away. While waiting for help, you can take steps to cool the person down. Move them to a shaded or air-conditioned area, remove excess clothing, and use any available means to lower their body temperature. This could include a cool bath, spraying them with water, fanning them, or applying cold packs to key areas like the neck, groin, and underarms. The goal is to reduce their body temperature as quickly as possible, as every minute counts.

Certain groups are more vulnerable to heat stroke. Babies and young children have immature temperature regulation systems, while adults over 65 may struggle to adapt to heat. Physical activity in hot weather, especially for those unaccustomed to the climate, increases risk. Other factors include lack of air conditioning, certain medications (like diuretics or beta blockers), and pre-existing health conditions such as heart disease or obesity.

The good news is that heat stroke is largely preventable. Here are some effective strategies to protect yourself and your loved ones:

1. Wear lightweight, loose-fitting clothing made from natural fabrics like cotton or linen.
2. Use sunscreen and seek shade to prevent sunburn, which can hinder your body’s ability to cool down.
3. Stay hydrated by drinking water regularly, even if you don’t feel thirsty.
4. Avoid outdoor activities during the hottest parts of the day, typically between 11 a.m. and 3 p.m.
5. Never leave anyone in a parked car, especially children, as even a few minutes can be deadly.
6. If starting a new exercise routine or traveling to a hot climate, acclimatize gradually to the heat.
