Opinion | Exercise Is Good for You, Even if You Have a Mild Case of Covid - The Wall Street Journal
The American College of Sports Medicine has suggested people under 50 who experience mild or no symptoms to rest for at least seven to 10 days after testing positive.
Their recommendation appears to be motivated by the concern that even a mild Covid-19 infection may damage the heart and potentially cause sudden death during physical exertion.
There’s little evidence to support this recommendation.
