What should you wear in an infrared sauna?

The best things to wear

• A swimsuit. Easy, quick-drying, and ready for the shower and cold plunge after.
• Loose cotton shorts and a tank or sports bra. Cotton breathes and soaks up sweat.
• Just a towel. In a private cabin, this is the most common choice and the most effective, because nothing blocks the light.
• Bare feet. Flip-flops to the door, then off.

What to leave in the locker

• Jewelry, watches, rings and piercings you can remove. Metal heats up fast and can get uncomfortably hot against the skin.
• Glasses and contacts if they bother you in heat; most people are fine with contacts for 30 minutes.
• Lotion, oils, makeup and perfume. They sit on the skin, block sweat and can feel sticky under heat. Come clean, moisturize after.
• Tight synthetic gear: compression tights, polyester leggings, sports tops that trap heat. They hold sweat against you and blunt the infrared.
• Your phone, if you can bear it. Heat is hard on batteries and the session is better without it.

What to bring

• Water. Drink a full glass before and bring a bottle in. You will sweat more than you expect.
• A second towel to sit on and one to dry off. We supply towels; bring your own if you prefer.
• A hair tie. Hair up keeps your neck cool and your towel dry.
• A change of clothes if you are heading out afterward. Loose and comfortable; your skin keeps sweating for a few minutes.

After the session

Sit for two or three minutes before standing, rinse or wipe down, and put on dry clothes. If you booked the cold plunge, take a quick rinse and head to the tub while you are still warm.
