How exercise effects the immune system

Everyone gets sick, it’s tough to know what to do about it. Do you exercise when you’re sick? or not? There is a difference between “working out” and “physically moving the body.” When we’re healthy, our bodies can easily adapt to the stress of a hard workout,  one where you’re breathing heavily, sweating, and working hard. Over time, this progressive adaptation is precisely what makes us fitter and stronger….But when we’re sick, the stress of a tough workout can be more than our immune systems can handle.In general, consistent, moderate exercise and resistance training can STRENGTHEN the immune system. So, train hard and heavy while you’re healthy. BUT single high intensity or long duration exercise sessions can interfere with immune function. So take it easy when you’re feeling sick.  In conclusion, there’s no reason to dive for your bed the minute you feel a cold coming on. Unless you’re severely out of shape, non-strenuous movement, such as walking and low intensity bike riding, shouldn’t hurt you, it might even help.
