Have you ever woken up feeling like your body got hit by a train overnight? Even though you feel fine otherwise, the mysterious aches from head to toe seem to come out of nowhere, and of course, they beg the question, why is my body sore? Sure, sometimes it's clear enough that the boxing class you took yesterday simply kicked your butt (and the rest of your body for that matter), but other times, the reasons behind the aches and pains just aren't all that obvious.
First of all, don't let yourself get carried away. Waking up feeling super sore and not knowing why doesn't necessarily mean you're dying, nor does it automatically mean you're going to lose control of all your major muscle groups. (These are definitely both things I have needlessly worried about when my body's felt sore for no apparent reason.)
There are tons of factors that could potentially be at play when you're feeling achey all over, and some of them might not be what you initially expect to be the cause. So, take a deep breath, remind yourself that everything will be OK, and consider one of these potential causes if you can't figure out why the hell you're so freaking sore.
And then maybe take a long, hot bubble bath, and treat yourself to a massage.
