Heat wave threatens: Be careful of circulatory problems and exhaustion!
Summer is just around the corner, and with it a significant change in the weather in Germany brings not only rising temperatures, but also health challenges. From the coming weekend, peak values of up to 33 degrees Celsius are expected, meaning that warm, humid air masses will flow into Germany from southern regions. According to FNP, Ascension Day and Bridge Day could invite you to go out with pleasant temperatures, but from Saturday night onwards the increasing humidity will have a negative impact on your health risks involved.
Seniors, small children, pregnant women and people with chronic illnesses are particularly at risk. According to an analysis by AOK, the consequences of extreme heat, including circulatory problems, headaches and exhaustion, can be serious. Circulatory problems often arise because the body has difficulty maintaining body temperature at a healthy level. In extreme heat, the blood vessels dilate, which can lead to a drop in blood pressure. The symptoms are varied and range from nausea to dizziness to skin rashes.
Health risks in hot weather
Health authorities point out that heat-related deaths are often not directly attributable to the heat. According to RKI, the statistics of heat-related mortality are determined by comparing deaths in hot and cool summer weeks. While hot days are rarely considered the sole cause of death, when combined with pre-existing conditions such as heart or lung disease, they can have fatal consequences. From an average weekly temperature of 20°C, the mortality rate increases, especially among older people.
The coming days will bring a significant change in the overall weather situation. To protect your health, experts recommend avoiding outdoor physical activity and ensuring you drink enough fluids. Windows should also be closed during the day and ventilated early in the morning or evening. Blinds can help keep interiors cool. Pets also need special protection from overheating.
Overall, it is important to find out about the dangers of heat waves in order to take preventative measures and protect your own health and that of other people and animals.
