Too much intense excercise could be bad for your immunity, according to the Washington Post. One study, following runners at the 1987 L.A. Marathon, found that those who completed the marathon got sick at a rate of 5.9 percent higher than those who didn't finish. Study head David Nieman says that excessive exercise likely drains the body of glycogen, the body's main energy source. “Your brain registers the lack of glycogen, and then you get the negative immune response,” he says. Another study followed the Finnish team at the 2018 Winter Olympics, and found 45 percent of its members got a cold during the 21-day observation period that surrounded the games.
“Regular exercise boosts immunity, very hard efforts temporarily lower immunity, and chronic overtraining lowers immunity in more enduring ways,” says Brad Stulberg, a performance coach. “I recommend getting out every day and engaging in a moderate level of activity, but don’t take it to a point where you are chronically tired.”
