Cold Plunge, Saunas, and Red Light Therapy: Recovery Tools or Wellness Hype?

Cold plunges, saunas, and red light therapy are popular recovery tools—but they are not magic buttons.

For physical therapists, the best use of these modalities is not selling certainty. It is helping patients ask better questions:

• What are you trying to recover from?

• Is this safe for your health history?

• Is it helping you move, sleep, train, or feel better?

• Is it replacing something more important, like progressive loading, sleep, nutrition, or medical care?
