How to prevent the health risks of a heat wave
Prolonged heat increases the risk of dehydration and heat exhaustion, and in the worst cases, can lead to heat stroke. Heat can also worsen existing heart and respiratory conditions. The elderly, children, people with chronic illnesses, those who do physical labor, and people who live alone are particularly vulnerable to the effects of heat.
Preparing for heat waves comes down to basic everyday precautions: drinking enough water, staying in the shade or in cool places, and avoiding hard physical exertion during the hottest part of the day. Wearing light clothing, protecting yourself from the sun, and eating regularly help you cope. It is also important to look out for loved ones, especially those in high-risk groups.
It’s a good idea to air out your home especially at night and early in the morning, when the outside air is cooler, and to keep windows and curtains closed during the hottest part of the day. Direct sunlight should be blocked using, for example, blinds, curtains, or external sunshades. You can lower your body temperature by taking cool showers, chilling your sheets in the freezer, or spending time in the cooler rooms of your home.
In addition, it’s a good idea to reduce the use of non-cooling electrical appliances and household devices during the hottest parts of the day, as they generate additional heat indoors.
