With the boom of the fitness injury, more and more people are finding it’s just as – if not more! – important to emphasize recovery as it is to focus on those healthy gains.

Anna Kaiser told us the infrared sauna is her number one self-care treatment for active women. “It decreases inflammation, increases muscular recovery, decreases recovery time, and is a really nice way to decompress without dehyrdating yourself," she told POPSUGAR. "It’s heating from the inside out – you give your bones and joints and tissue a release."
