Is exercise good for the immune system? For most, the benefit of exercise is simple – weight loss and building muscle. But the benefits of exercise go beyond the surface. Studies have shown that regular exercise can improve one’s immune system and overall well-being.
Can running weaken your immune system? Running 10 miles or more or running to exhaustion can actually temporarily weaken the immune system. This impairment of immune function generally lasts only for a few hours, although for some people, it may take several days, especially for those with an already weakened immune system.
