Why You Shouldn’t Play it Cool When it Comes to Heatstroke

This serious and life-threatening condition occurs when the body’s temperature regulation system is overwhelmed by heat.

The recent deaths of two children in Kelantan from heatstroke has prompted the health ministry to send out warnings, driving home the fact that Malaysia’s high temperatures cannot be taken lightly.

A serious medical condition that requires immediate attention, heatstroke occurs when the body’s temperature regulation system is overcome by heat. Symptoms may include:

• A high body temperature above 40°C;
• Rapid heartbeat;
• Rapid or laboured breathing;
• Headache, dizziness or lightheadedness;
• confusion or disorientation;
• Nausea or vomiting;
• Seizures; and/or
• Loss of consciousness.

Emotional sensations such as anxiety and agitation, and a sense of being overwhelmed can also occur due to the body’s response to high temperatures. Failure to treat heatstroke could lead to organ damage or be fatal.

That said, it can sometimes be difficult to differentiate between someone who is simply hot and sweaty, and someone who is experiencing heat exhaustion.

With the latter, one’s body temperature typically rises above 40°C. The skin might feel dry and hot, causing sweating to stop altogether.

In contrast, those who are merely exerted usually continue to perspire, and are unlikely to experience the symptoms above.
