The sun’s rays have positive effects on people: they encourage metabolic processes, lift our mood and help us relax. However, the sun’s ultra-violet rays can be damaging in both the short and long term. Today, more and more people suffer from skin problems brought on by sunlight. Between 50 and 70 percent of skin cancer cases result from excessive exposure to sunlight.

Switzerland ranks among the top ten countries in terms of incidence rates for skin cancer (WCRF, 2020). Every year 22 new cases of melanoma are diagnosed in Switzerland for every 100 000 people. Cases of non-melanoma skin cancer are even higher: around 50 per 100 000 people.

Mountains and lakes on our doorstep give ample opportunities for outdoor pursuits, and sunshine exposure and the associated risks are particularly high at this latitude.

Studies show that people are often not aware of the risks posed by natural and artificial ultra-violet light or of effective prevention measures.

CERN’s Medical Service has invited the Ligue Genevoise contre le Cancer (LGC) to host a prevention campaign that will take place on 27 June from 10.00 a.m. to 3.00 p.m. in the foyer of the Main Building (outside Restaurant 1). At the stand, you’ll find out more about the impact of the sun on our health and what you can do to protect yourself from its harmful effects.
