Ever wondered if your favorite accessories can handle the heat? To navigate the do’s and don’ts of sauna essentials, we turned to Andrei Blui Newman, founder of Casa Blui, a luxury home wellness company specializing in custom saunas, luxury spas, and cold plunges. With Casio developing a sauna-proof watch and Oura declaring its smart rings sauna-safe, the spotlight is on how we accessorize our sauna sessions. But not all items play nice with high heat and humidity.

Andrei shares his ultimate guide to what belongs in the sauna—and what you should leave at the door.
Hot Picks for Sauna Success:
Turkish Towel
“Turkish towels are the best towels for saunas because they’re thin and easy to carry but also highly absorbent and quick-drying,” Andrei explains. Lightweight and luxurious, they’re a must-have for maximizing comfort during your sauna session.
Large, Non-Glass Water Bottle
“Hydration is key,” says Andrei. “Staying hydrated before, during, and after your session helps regulate body temperature and prevents dehydration.” A durable water bottle made from stainless steel or titanium is ideal for withstanding sauna temperatures.
Dedicated Sauna Sandals
“For private saunas, go barefoot to maximize skin exposure. For shared spaces, choose non-slip mesh or EVA foam sandals for hygiene,” advises Andrei. These lightweight and heat-resistant options ensure comfort and safety.

Things to Leave Behind:
Your Phone
“Electronics and humidity don’t mix,” Andrei warns. “Saunas can also overheat smartphones, causing them to malfunction.” To stay present and protect your devices, keep them out of the sauna.
Metal Jewelry
“Hot metal equals skin burns,” Andrei explains. Instead, opt for silicone rings and bracelets, which are heat-safe and stylish alternatives.
Glass Water Bottles
“Glass in a sauna is a hazard,” he emphasizes. Stick to durable materials like stainless steel or titanium for a safer and healthier hydration experience.
Health Benefits of Saunas:
Beyond relaxation, saunas offer an impressive range of health benefits:
- Detoxification: Sweating helps flush toxins from your body, improving overall health.
- Improved Circulation: The heat boosts blood flow, promoting cardiovascular health.
- Stress Relief: Sauna sessions stimulate endorphin release, helping to reduce anxiety and improve mood.
- Skin Health: Heat and humidity open pores, aiding in deep cleansing and glowing skin.
- Muscle Recovery: Saunas can alleviate muscle soreness and speed up recovery after workouts.
