Sauna vs Infrared vs Hot Bath… guess who wins?

Wait… a bath might be just as (or even MORE) beneficial than a sauna?!

Sauna vs Infrared vs Hot Bath… guess who wins?

A new study compared all three for heat therapy benefits—and the surprise wasn’t subtle.

Hot baths came out on top.

Not only did they raise core body temperature the most, they were the only method that boosted natural killer (NK) cell activity—your immune system’s front-line defenders.

Traditional sauna and infrared still have benefits…but if your goal is deep heat + immune activation, the humble hot bath might be the MVP.

Simple. Accessible. Powerful.

Sometimes the old-school way wins.
