Moving your body regularly can take your mind off of any worries or fears. For instance, yoga is a very mindful practice (as should any form of exercise be!). This means that it’s hard to focus on anything else when you’re trying to pay attention to where your body is in space, as well as moving with your breath.
The same goes for any intense activity. It’s tricky to focus on anything else when you’re trying to perform 10 or so burpees. It’s also encouraged, during weightlifting or strength training, to actually focus on the muscle you’re contracting, as this can activate more muscle fibers during the movement itself.
The takeaway here? Everyone should be performing regular exercise. In fact, when we’re in good shape, the body is more resilient to stress as there is less inflammation interfering with our body’s regular processes.
