Sauna Before Bed: How Heat Improves Your Sleep
A sauna before bed helps you sleep because the drop in your core temperature after you leave the heat is one of your body's strongest signals to fall asleep. Core-temperature drop is the natural cooling your body does as it winds down for the night. A warm sauna, then a cool room, exaggerates that shift and helps you drift off faster.
Why heat before sleep actually works
Your body runs on a daily temperature rhythm. It peaks in the late afternoon and starts falling in the evening. That fall is tied to the release of melatonin and the feeling of drowsiness. When your core temperature drops, your brain reads it as a cue that it is time to sleep.
A sauna session works with that rhythm instead of against it. Our saunas run around 190 to 200°F with real loyly (steam from water poured over hot stones). While you sit in the heat, your core temperature rises and your blood vessels open near the skin to shed warmth. When you step out into a cooler room, your body dumps that heat fast. Your core temperature falls below where it started, and that steeper drop is what tells your brain to power down.
In plain terms: heat up, cool down, sleep. The cooling is the point. The sauna is just the tool that makes the cooling more dramatic.
Where the cold plunge fits
Contrast therapy is the practice of alternating hot and cold. At Loyly, that means moving between the sauna and an individual cold plunge. Our plunges come in four temperatures (41°F, 46°F, 51°F, 56°F), with no chlorine and no bromine. We keep them clean with continuous UV-C sanitation, automated ozone injection, 50-micron filtration, and water changed daily.
A cold plunge in the evening is a lever, not a rule. Cold is stimulating for many people, so if you plunge, keep it short and finish your session in the sauna or a warm rinse so your body still gets the gradual cool-down afterward. If cold wakes you up too much at night, skip it and stick to heat. Warmer plunges (51°F and 56°F) are a gentler way to include cold without a big jolt. You can read more about picking a temperature in our cold plunge temperature guide.
How to time an evening sauna for sleep
The goal is to finish with enough time for your body to cool before you lie down. Here is a simple order of operations for a wind-down session.
- Arrive with time to spare. There are no appointments and no time limits, so you set the pace. Give yourself at least an hour.
- Warm up in the sauna. Sit until you feel genuinely warm and loose. This is the part that raises your core temperature.
- Cool down deliberately. Step out, sit in the cooler air, and let your body shed heat. Add a short, gentle plunge here if it agrees with you.
- Repeat if you like. One to three rounds is plenty. Let your last round end with cooling, not heating.
- Leave 60 to 90 minutes before bed. That gap lets your core temperature settle into its downward slide right as you want to sleep.
If you want the quiet version, use the silent sauna. Every location has both a social sauna and an enforced silent sauna, so you can choose calm over conversation on a night you are trying to wind down. See our sauna etiquette guide for how each room works.
Our hours make evening sauna easy
You do not need a reservation. Walk in during operating hours and stay as long as you want. Here are the hours across all three locations.
| Days | Hours |
|---|---|
| Monday to Thursday | 6:00 am to 9:00 pm |
| Friday to Saturday | 6:00 am to 10:00 pm |
| Sunday | 8:00 am to 2:00 pm |
Weeknights close at 9:00 pm, and weekend nights run until 10:00 pm. That gives you room to come in after work or after dinner and still make it home for that cool-down window before bed. Find the location nearest you on our locations page: Orem, Downtown Salt Lake City, and Fort Union in Midvale.
Making it a habit
Sleep responds to routine. Doing the same wind-down at roughly the same time trains your body to expect sleep. That is where unlimited visits help. If you plan to build an evening sauna habit, a membership costs less per visit than paying a $30 day pass each time.
| Pass | Price | Best for |
|---|---|---|
| Lo Pass | $45/month | One home location, unlimited evening visits |
| Vetta Pass | $60/month | One location plus towel service and store discounts |
| Fjord Pass | $95/month | Every location plus towel service and discounts |
All passes include unlimited visits, unlimited time, and no appointments. Compare them in our membership guide or see full pricing on the memberships page.
One note: consistency beats intensity. A short, regular evening session you actually keep doing will help your sleep more than a marathon session once a month. For a sense of how often to go, read how often you should do contrast therapy.
Frequently asked questions
How long before bed should I sauna?
Aim to finish your session about 60 to 90 minutes before you lie down. That gap gives your core temperature time to fall, which is the drop that signals sleep. Ending with cooling rather than heat helps the process along.
Will a cold plunge before bed keep me awake?
It can for some people, because cold is stimulating. If you want to plunge in the evening, keep it short, consider a warmer tub (51°F or 56°F), and finish your session with a warm-then-cool wind-down. If cold leaves you wired, skip it and stick to sauna heat.
Do I need a reservation for an evening session?
No. There are no reservations, no appointments, and no time limits. Walk in during operating hours and stay as long as you want. Weeknights close at 9:00 pm and weekend nights close at 10:00 pm.
Is the sauna too hot right before sleep?
The heat itself is not the issue, since our saunas run around 190 to 200°F and the goal is the cool-down that follows. What matters is leaving time to cool afterward. If you feel overheated at bedtime, extend your cool-down and lengthen the gap before you sleep.
