Energy. It’s the currency you trade in to accomplish all of life’s tasks. Whether you’re parenting, competing in sports, or crushing deals in the boardroom, energy is the legal tender that puts ticks in boxes. Still, it’s become a limited resource that’s withering away from society. As many as 1 in 5 people now feel tired all the time without having any kind of medical reason. Sure, you can get cheap fixes by slamming another double espresso or adding an hour of sleep to your night. However, regular outdoor sauna sessions can reinvigorate your system, heal the energy blockers, and recharge your mind.
