Can sleep at altitude prevent sudden hiker deaths?

NEW YORK, May 17: Men who die of a sudden cardiac event are less likely to do so on the first day of mountain activities if they sleep at higher elevations the night before, according to a new study. ‘The recommendations now are if you’re an active, healthy person above about 8,000 or 9,000 feet, you should spend some time acclimatizing before you’re active. You should have a day of rest or more,’ said Bruce Johnson, a professor at the Mayo Clinic in Rochester, Minnesota. (AGENCIES)
