Temperatures of up to 36 degrees a day, even at night, it is currently cooling only to about 20 degrees: In Germany, it remains hot the coming days. Doing sports in this weather can be too much even for professionals. On Tuesday, 28-year-old Karim Bellarabi of Bayer Leverkusen collapsed in a friendly match - and had to spend the night in the hospital.
Coach Heiko Herrlich suspected that Bellarabi may have had too little to drink. "But in the heat of course it's extreme, even if you're not playing, it's a brutal burden on the organism," Herrlich said after the game.
If sport is risky even for professionals in the current heat - how should recreational athletes keep it?
Caution is especially important in sports that put a heavier burden on the circulation, says Tim Meyer from the Institute of Sports and Preventive Medicine at the University of Saarland: "These include endurance sports such as running but also cycling" and team sports.
