Heat Therapy as the Days Get Shorter
By mid-October the sun sets around 6:15 p.m. in New York, Chicago, and Seattle. That leaves a long stretch of evening, and the couch has a strong claim on it.
Here's our case for giving an hour of it to heat instead. This is how we'd spend a weeknight in October. Shift the times to fit yours.
5:45 p.m. Start it from the car
If you have a Plunge sauna, start the session in the Plunge app on your way home and it'll be hot when you walk in. Newer to heat? Our personal sauna practice guide suggests 165 to 175°F, two or three times a week. No sauna at all? A hot bath covers a lot of what follows. Harvard cardiologist Adolph Hutter suggests 100 to 105°F water, eased into slowly.
6:30 p.m. The first round
Open the door and the cedar hits first. Sit down, let out a long breath, and let the heat get to work. Within a few minutes your blood vessels widen, your blood pressure dips, and your heart picks up the pace, pumping close to twice as much blood per minute. You get something like the heart rate of an easy walk without leaving the bench.
Five to 12 minutes is plenty for a first round.
The numbers, briefly
Harvard Health's roundup of hot baths, saunas, and heart health covers two big studies. Finns who used a sauna four to seven times a week had lower blood pressure and a lower risk of heart disease and stroke. In a Japanese study of more than 30,000 people, near-daily hot baths were linked to a 28% lower risk of cardiovascular disease. Both are observational, and the pattern holds across two very different bathing cultures.
6:45 p.m. Cool down
Step out, drink some water, and let your heart rate settle. If you're a contrast person, this is the plunge moment. If not, a lukewarm shower or a few minutes on the porch in the October air does the job.
7:00 p.m. Another round, or call it
Ladle a little water on the stones, listen to the hiss, and decide. Frequency seems to matter more than duration, so a session you'll happily repeat on Thursday beats one that flattens you. Forbes Health's roundup of sauna benefits adds a few reasons people keep coming back, including lower stress hormones. In one small survey, 83.5% of regular sauna users said they slept better.
9:30 p.m. Lights out
By now your body has shed the heat, and that drop in core temperature is one of the cues for sleep. Many people find they're ready for bed earlier, and a lot less wired than after a night of scrolling. If you feel buzzy instead, move the session earlier next time.
The night you feel a cold coming on
Our post on whether the sauna is good for a cold notes that warm, humid air can ease congestion for a while. Forbes quotes a physician who says to skip the sauna when you're unwell. Here's where we land. With a mild head cold, no fever, and normal energy, a shorter, cooler session may feel great. With a fever, aches, or anything flu-like, stay on the couch. You've earned the couch.
A word for your heart
Heat asks a lot of it. If you have unstable angina, poorly controlled blood pressure, or a serious heart condition, or you're pregnant, get your doctor's OK first. Skip the sauna after a drink, and keep any single round to 15 or 20 minutes.
Tomorrow
Pick one night this week and put the sauna on your calendar like a meeting, 6:30 to 7:15. If you have a Plunge sauna, set up the session in the app now, so the only decision left is which towel.
