Can an Infrared Sauna Help You Sleep? Temperature, Timing, and Tips

After a busy day, switching off can feel harder than staying busy. A quiet sauna session offers a chance to pause, enjoy the warmth, and create space between the day’s demands and bedtime.

An infrared sauna may support relaxation and better sleep for some people, but researchers have not established an ideal sauna temperature for sleep. For beginners, around 110°F (43°C) for 5–10 minutes is a general starting point—not a proven sleep treatment. Follow your sauna’s instructions and your individual heat tolerance.

Why Might Sauna Help You Sleep?

Warming up may help your body prepare to cool down

Your body’s temperature regulation is closely connected to sleep. As bedtime approaches, releasing heat through the skin helps your core temperature decline.

A 2019 systematic review found that warm baths or showers taken 1–2 hours before bed were associated with faster sleep onset and improvements in some measures of sleep quality. Researchers linked these effects to increased heat loss after warming. Review in Sleep Medicine Reviews

That offers a plausible explanation for why an evening sauna might help some people settle down. However, baths and infrared saunas deliver heat differently. Bath research does not establish a proven infrared sauna temperature, duration, or sleep benefit.

A sauna creates time to unwind

Warmth, quiet, and a break from everyday distractions can make a sauna session an appealing evening ritual.

In the 2019 Global Sauna Survey, 83.5% of 482 respondents reported sleep benefits after sauna use. Relaxation and stress reduction were also common reasons for using saunas. Because this was a survey of sauna users, it cannot prove that sauna caused better sleep or that everyone will experience the same result. Global Sauna Survey

Think of sauna as a possible addition to your wind-down routine, with results that depend on how you respond.

What Infrared Sauna Temperature Should You Use Before Bed?

There is no scientifically established “best infrared sauna temperature for sleep.” A comfortable, moderate session is a more useful starting goal than reaching the highest setting.

Cleveland Clinic describes typical infrared sauna temperatures as approximately 110–135°F (43–57°C) and recommends that beginners start around 110°F (43°C) for 5–10 minutes. These are general sauna-use guidelines, not a sleep-specific prescription. Infrared sauna temperature and duration guidance

For a WizziSauna evening routine, check the instructions for your specific model and begin conservatively. You do not need to increase the heat simply because a higher setting is available.

For example, the WizziSauna SH01 product specifications list a maximum temperature of 158°F (70°C). That product capability should not be interpreted as a recommended bedtime setting.

When Should You Use an Infrared Sauna Before Bed?

Allow time afterward to cool down comfortably before getting into bed.

Finishing about 1–2 hours before bedtime is a reasonable timing option to try, extrapolated from warm-bath research. It is not a validated infrared sauna sleep protocol. If an evening session leaves you feeling alert or overheated, try an earlier session or reconsider whether sauna fits your bedtime routine. Research on warming before bedtime

Avoid treating the clock as a strict rule. How you feel afterward matters.

Keep the ritual easy to repeat:

1. Choose your time. Leave room between your session and bedtime.

2. Follow your model’s instructions. Use a comfortable setting and start with a short session.

3. Make space to relax. Set work aside and enjoy a few quiet minutes.

4. Cool down afterward. Give yourself time to feel comfortable before bed.

5. Notice your response. Record the setting, session length, and how you slept. Look for a consistent pattern before deciding whether it helps.
