Infrared saunas offer a gentler, more accessible entry point into heat therapy by using light to warm your body directly rather than heating the air around you. To get started safely, the golden rule is to prioritize hydration and limit your first few sessions to 10–15 minutes at a moderate temperature. Unlike traditional steam saunas, the goal here isn't to endure extreme heat, but to allow the infrared waves to penetrate your tissues at a pace your body can handle. If you are brand new to this practice, checking out our start-here guide can help you frame your overall wellness goals.
Setting the Right Temperature and Timing
For your first few sessions, resist the urge to crank the heater to its maximum setting. While many infrared saunas can reach 150°F (65°C) or higher, beginners often find the most benefit—and the least discomfort—at lower ranges.
Recommended Temperature
Start between 110°F and 125°F. This range allows your cardiovascular system to adapt to the heat without causing immediate stress. As you become more experienced, you might choose to increase this, but remember that the biological effects of infrared occur even at lower ambient temperatures.
How Long Should You Stay In?
Begin with 10 to 15 minutes. Even if you feel like you can go longer, your body needs time to learn how to thermoregulate in this specific environment. Once you are comfortable and aren't experiencing lightheadedness, you can gradually add 5 minutes to each subsequent session until you reach a standard 30-minute routine.
What to Wear and Bring Inside
The more skin exposed to the infrared emitters, the more effective the session will be. Most users prefer a light towel or very loose-fitting cotton shorts. Avoid synthetic fabrics that don't breathe well, as they can trap heat and sweat against your skin uncomfortably.
Always bring a dedicated "sweat towel" to sit on. This protects the wood of the sauna from moisture and oils, which is a key part of sauna maintenance and hygiene. You may also want a smaller hand towel to wipe your face during the session.
The Importance of Hydration
Sweating is the primary mechanism of an infrared sauna, and you will lose more fluid than you might realize. Dehydration is the most common cause of the "sauna hangover" (headaches or fatigue) that beginners sometimes report.
- Before: Drink at least 8–16 ounces of water or an electrolyte-rich beverage.
- During: Sip water if you feel thirsty, though many prefer to wait until after.
- After: Replenish with another 16 ounces of water and consider adding minerals like magnesium and potassium to your post-sauna meal.
Safety and Listening to Your Body
While infrared saunas are generally considered safe for healthy individuals, they do put a temporary strain on the heart and circulatory system. It is vital to follow basic sauna safety protocols to ensure a positive experience. If at any point you feel dizzy, nauseous, or develop a throbbing headache, exit the sauna immediately and cool down slowly.
Before starting any new heat therapy regimen, please review our medical disclaimer and consult with a healthcare professional, especially if you have underlying heart conditions, are pregnant, or are taking medications that affect your ability to sweat.
Beginner FAQ
Do I need to shower before or after?
A quick rinse before helps remove lotions or oils that might block pores. A lukewarm shower after is highly recommended to wash away the salt and toxins released through your sweat.
How often should a beginner use the sauna?
Start with 2 to 3 times per week. This gives your body plenty of time to recover and allows you to monitor how the heat affects your sleep and energy levels the following day.
Can I use my phone inside?
It is generally discouraged. The heat can damage sensitive electronics and batteries. Furthermore, the sauna is an excellent time for a digital detox to maximize the relaxation response.
