Gentle stretches, walking, and periodically standing up at your desk can help stabilize your spine and prevent muscle imbalances. And despite how hard it is to imagine doing Downward-Facing Dog with a bad back, yoga can work in your favor, too. A 2013 review of studies found strong evidence it can help beat lower back pain.

Traditional wisdom says that NSAID pain relievers only damage your gut lining if you take them every day for a long time, but recent research disagrees. High-level athletes with stress-related intestinal damage tried taking ibuprofen to improve muscle soreness and recovery. Ibuprofen ended up damaging their gut lining even further after just a couple weeks; it increased inflammation and made their original pain issues worse. In fact, a single dose of aspirin can significantly increase your intestinal permeability.
