Are Saunas the Next Big Performance-Enhancing “Drug”?

For the most part, people don’t like to get hot.

The massive indoor climate control systems and pleasantly chilled water fountains found in most gyms speak to this fact. There are some exceptions — Bikram yoga, for example — but they’re few and far between.

But here’s the surprise: increasing your core temperature for short bursts is not only healthful, it can also dramatically improve performance.

This is true whether it’s done in conjunction with your existing workout or as an entirely separate activity. I’m going to explain how heat acclimation through sauna use (and likely any other non-aerobic activity that increases core body temperature) can promote physiological adaptations that result in increased endurance, easier acquisition of muscle mass, and a general increased capacity for stress tolerance. I will refer to this concept of deliberately acclimating yourself to heat, independent of working out, as “hyperthermic conditioning.”

I’m also going to explain the positive effects of heat acclimation on the brain, including the growth of new brain cells, improvement in focus, learning and memory, and ameliorating depression and anxiety. In addition, you’ll learn how modulation of core temperature might even be largely responsible for “runner’s high” via an interaction between the dynorphin/beta-endorphin opioid systems.
