Human health

Climate change has considerable public health implications. In this NCCS focus area (‘priority theme’), the Federal Office of Public Health (FOPH) is working with the Federal Office for the Environment (FOEN) to compile knowledge bases and formulate preventive measures to protect the public from the health-related effects of increasing heat stress.  

According to climate scenarios, the kind of hot summers seen in 2003, 2015 and 2018 will be increasingly frequent, intense and longer-lasting in the future. The effects of heat on people’s health are varied and complex, and can result in death: in the hot summer of 2003, around 1,000 more people (+6.9%) died than is usual at that time of year; the estimated figure for 2015 was 800 (+5.4%). In summer 2018, the overall mortality rate was only 1.2% higher than normal; during the August heatwave north of the Alps, however, it was 3.4% higher. 

The elderly and chronically ill are most likely to die of heat stress. Deaths are particularly likely to occur when daytime temperatures exceed 30 degrees Celsius and the night-time temperatures do not fall below 20. There are also more emergency admissions to hospital when the weather is hot. 

As yet, there has been little investigation of the effects of extreme temperatures on people’s wellbeing, quality of life and performance in Switzerland.

Goals

The particular goals of the “human health” NCCS priority theme are as follows:

  • The Confederation will have up-to-date knowledge bases covering the effects of climate change on human health and focusing particularly on heat.
  • The Confederation will make knowledge-based information and materials concerning effective prevention measures available to the public, professionals and authorities.

Highlights

Knowledge bases 

As part of the priority theme, research is being done at the Swiss Tropical and Public Health Institute (Swiss TPH) into the effects of heat on health:

 

A summary of the «2018 summer heatwave» report can be found here on pages 30-39. (in German)

Information material for members of the public and professionals

Following the hot summer of 2003, the FOPH and FOEN compiled information material. This information creates awareness of the dangers associated with heatwaves and gives people tips on how to protect themselves during one. The material, which is intended both for professionals and for members of the public, was updated in 2016. Flyers and posters can be ordered free of charge (in German, French and Italian) from the www.hitzewelle.ch website.

Toolbox of measures for the authorities

In 2017 the Swiss TPH produced a toolbox of measures to help cantonal authorities deal with heatwaves – and in particular to draw up a heatwave action plan.

 

Cantonal measures can help reduce heat-related mortality:

 

Partners

The Federal Office of Public Health (FOPH) manages this area of focus in cooperation with the Federal Office for the Environment (FOEN). The basic scientific work is conducted by the Swiss Tropical and Public Health Institute (Swiss TPH) on behalf of the FOPH and FOEN.
