When the weather becomes very hot, the body has to work harder to maintain a normal temperature. This can lead to dehydration because you sweat more.
At the same time, the body loses essential salts. According to Diastyl, as cited by Dagens.dk, it may therefore be necessary to drink extra fluids and, in some cases, replenish electrolytes.
The risk is particularly high for people with cardiovascular disease, but healthy individuals can also be affected if they become overheated or dehydrated.
Small choices make a difference
According to Diastyl, cardiologist Aleš Linhart recommends avoiding strenuous exercise during the hottest part of the day.

A walk early in the morning or later in the evening is a better option.
Alcohol can further dehydrate the body, while energy drinks high in caffeine may place additional strain on the body.
For this reason, the combination of alcohol and energy drinks is especially discouraged.
If you use air conditioning, the difference between the outdoor and indoor temperatures should not be too great.

Pay attention to the warning signs
People who take medication for high blood pressure or heart failure should be especially cautious during hot weather.
If treatment needs to be adjusted, it should always be be done in consultation with a doctor, Diastyl says.
If a person becomes dizzy, feels unwell, or appears confused in the heat, they should be moved to a cooler place and given fluids.
If severe symptoms develop or the person loses consciousness, emergency services should be called immediately.
