Summer temperatures can be great for outdoor leisure activities, but can take a real toll on our bodies if we engage in more vigorous physical activity. This is especially true for individuals with cardiovascular medical conditions such as Coronary Artery Disease (CAD), as the combination of physical exertion with the body’s diminished thermoregulatory capability can have adverse effects on overall health.

Be especially careful

1. Overweight individual

Overweight individuals are more vulnerable to cardiovascular complications, therefore they should be extra careful in the heat.

A car can reach 40 ºC when temperatures are only around 15 ºC. Heat exhaustion can take place when the outside temperature is as low as 13 ºC.

3. Elderly & Children

Elderly and children are especially prone to heat exhaustion because their bodies can’t adjust to sudden changes in temperature so well.
