I’ve recently gotten into yoga and have noticed that the next morning, I’ll sometimes wake-up with an itching sensation that feels like it’s coming from inside my muscle tissue. I didn’t know whether that was cause for concern, so I started doing a little internet research find out.
What I discovered is that an itching sensation isn’t necessarily a bad thing and that if your itching only happens when you exercise, you likely won’t have any other symptoms.
People complain of itchy muscles especially in warm weather or if it’s been a while since they last exercised. Exercising, especially cardio workouts like running, increase your blood flow and send a lot of oxygen to your muscles. The theory is that the blood vessels in your muscles are stretching beyond what they’re used to, and this wakes up the nerves around them.
And since the nerve signals that communicate pain can sometimes be closely linked with the nerve signals for itch, itching muscles could also be a way that your body is processing stress from working out.
So next time you workout and your muscle fibers start to itch, that’s probably a good sign. Just remember to keep stretching and not to push your muscles to the point of strains or tears.
