High temperatures affect health: direct heat can weaken people, indirectly worsening their health through altered plant life and pollen season. Or mosquitoes and ticks spread – and with them pathogens.

What is a “heat wave” and how does it affect your health?

A heat wave occurs when the temperature is above 30 ° C for several days and does not drop below 20 ° C at night. This climatic situation can pose a health risk. For elderly or (chronically) ill people, pregnant women or infants, it can even be life-threatening. It can lead to cardiovascular and respiratory diseases. The reason for this is impaired heat regulation. You then sweat less and feel a diminished thirst.

Heat and mortality

In its technical risk report 2015, the Federal Office for Civil Protection (BABS) classified heat waves as one of Switzerland’s biggest threats.

Since 2005, together with the Federal Office for the Environment (FOEN), we have provided information on heat waves and behavioral recommendations. With them, we want to raise the awareness of those at risk, relatives, nurses, physicians and other stakeholders.

In the hot summer of 2003, Switzerland recorded an additional heat-related mortality of 975 people (7%). In particular, people over the age of 65 were affected. By comparison, around 70,000 people throughout Europe died from the prolonged heat.

High temperatures and ozone

High temperatures also increase ozone levels. These also affect the health, for example, when the respiratory tract is irritated or inflamed.

Information about Ozone observation can be found on the website of MeteoSwiss.

Influence on plant life and pollen season

Climate change is also affecting the plant world: Imported non-native plants (neophytes) are increasing. These can burden allergics increasing. Ambrosia is one such example. She has highly allergenic pollen. Because she can flower from mid-July to early October, she extends the allergy season by several weeks.

Climate change favors disease transmission

Long-lasting, high temperatures also favor an excessive mosquito and tick increase. They can carry pathogens that cause infectious diseases. For more information, see Vector transmitted diseases, Vector-borne diseases are infectious diseases in which so-called vectors, e.g. B. mosquitoes or ticks that transmit pathogens to humans.

Climate change also favors the emergence of existing or emerging infectious diseases, for example dengue or Chikungunya fever and the spread of through Ticks of transmitted encephalitis
