It’s a Scorcher!

We await the glorious days of summer to allow us to bask in the heat of beautiful days. We have become increasingly aware of sun safety and the use of sunscreen to prevent skin cancer. However we often overlook the importance of caution in the heat. Climate change has resulted in a great number of extreme heat days. 

Prolonged exposure to heat, particularly when engaged in sport, can lead to heat exhaustion and heat stroke. Heat exhaustion is associated with cool clammy skin, dizziness, fatigue, headaches, muscle cramps and weakness. Immediate response would involve moving to a cooler place, perhaps in the shade, stopping physical activity, and drinking fluids, including sports drinks or oral rehydration liquids. If dizziness or feeling faint persists, it is important to seek medical attention immediately.

Heat stroke occurs when the humidity is elevated and we are not able to maintain our body temperature as our ability to sweat is impaired by the high humidity. The body’s temperature is elevated. This can cause damaging effects to the central nervous system, leading to confusion, delirium and decreased level of consciousness. It is important to seek medical attention immediately as appropriate cooling and hydration are required.

This summer, watch the weather for both heat warnings and for the humidex. Avoid being outdoors during heat warning times. In particular, limit times for running or sport to times when the humidity and temperature are more tolerable. Keep hydrated with a variety of fluids. If you are out on a hot day, keep sports drinks with you to get valuable electrolytes along with fluids. 

Enjoy the summer but don’t get scorched!!
