Infrared Sauna in Peterborough: Why Fall and Winter Are Its Real Season
Back in June we made the case for using an infrared sauna in summer, which is a slightly harder sell. Heat therapy when it's already 30 degrees is only for the bold.
This is the easy one.
By the middle of October in Peterborough, it's dark before you finish work. The mornings are feeling crisper. Whatever you were doing outside all summer has wrapped up, and the motivation to replace it with something indoors takes a few weeks to show up, if it shows up at all. This is the stretch of the year when a lot of us just start to go into hibernation mode: less movement, less daylight, less energy.
An infrared sauna is one of the simpler things you can put back into the fall season.
Here's what it actually does, how often is worth it, and what it costs to use it regularly rather than occasionally.
Fall Is When an Infrared Sauna Routine Makes Sense
Our sauna at Flow Spa in Peterborough is a two-person far infrared unit with ceramic heaters. It runs around 155°F, which is meaningfully cooler than a traditional Finnish sauna at 185°F and up. Infrared warms you directly rather than heating the air around you, so you work up a sweat and get a deep, steady heat that most people find comfortable to sit in for a full half hour.
In July, thirty minutes of that is a mental toughness challenge. In November, it becomes the best your body has felt all week.
That difference matters more than it sounds. The recovery modality you'll actually use is the one that feels good to walk into. Fall and winter are when the sauna stops being a discipline and starts being the thing you look forward to, which is exactly when a healthy habit has a chance of sticking.
What the Heat Is Doing
Most of the research on sauna benefits comes down to hyperthermia, which is the effect of heat on the body, and it’s why the findings apply to far infrared saunas like ours as well as traditional ones.
The scientifically supported effects:
Circulation. Heat brings blood to the surface and gets things moving. Many people notice this most in cold hands and feet through the winter.
Recovery and thermoregulation. Sauna use has been shown to support athletic recovery and performance, which is part of why it sits in our sports recovery room next to the cold plunge.
Muscle and joint ease. The heat helps tight, cold, guarded muscles let go, which is a common complaint from about November onward.
A genuine pause. Thirty minutes where you put your phone away is doing something on its own, separate from the heat.
Plenty of our regulars tell us the sauna helps them get through the darker months, and warmth and routine are legitimately useful things in winter. But an infrared sauna is not a treatment for seasonal depression, and if the winter is genuinely flattening you, that deserves proper support. We have psychotherapy at Flow Spa for exactly that reason, and it pairs well with the rest of what we do.
The Frequency Question
One sauna session feels good for an evening.
Regular sessions are a different experience to how your fall and winter will feel. Most of the research showing meaningful benefit involves consistent use over time, not a single visit, and anecdotally that matches what we see: the clients who get the most out of the sauna are the ones who come weekly or better through the winter, not the ones who come for a one-off session.
Which raises the real problem. At $32 a session, once a week for four months is around $550. That's the point where most people decide they'll go occasionally instead, and see little gain from a few interspersed sauna sessions.
What Regular Infrared Sauna Use Costs in Peterborough
So here's the practical version, with the real numbers.
If you're going a couple of times a month, the sauna packages are the simplest option: 4 x 30-minute sessions for $80, used within 40 days. That's $20 a session instead of $32. There's also a 4-session sauna and cold plunge package for $110, and a couple's version at $120.
If you want to go weekly or more, the Unlimited Membership is $150 a month and covers unlimited daily credits for any length of float, any sauna or contrast option, and Normatec. You can book each service daily, even coming back at different times of the day. So if you want to sauna every day, or multiple times per week, this new Unlimited Membership was designed for you.
The math is straightforward. Five sauna sessions a month gets you past what you'd pay at the drop-in rate, and five sessions is roughly once a week plus one. Everything after that is included, along with floats, contrast therapy, and Normatec, which is where it turns into a full recovery system to feel your best.
Two things worth knowing before you decide:
If you're realistically going twice a month, the $80 four-pack is better value than the membership. We'd rather tell you that than sell you something you won't use.
The Unlimited is also available as a one-month package that doesn't renew. That's a good way to take a single month, say the worst stretch of January, and go as often as you want without committing to anything ongoing.
Memberships need to be activated by our staff on Jane, so get in touch and we'll set it up.
Fall Is Also When Contrast Therapy Heats Up
If you've been curious about the cold plunge, going into winter is a good time to start, because the sauna makes the cold approachable in a way that a standalone plunge never quite is.
The full contrast room gives you an hour with the infrared sauna, hot tub, and cold plunge for $47 solo or $57 for two people. A 30-minute sauna and cold plunge combination is $42. If you're new to it, we walk through the how-long-and-how-many-rounds question in Contrast Therapy 101.
There's also a nice seasonal argument for it: getting deliberately cold in a controlled way, then getting warm again, is a reasonable thing to practise in a Peterborough winter, which is going to do it to you involuntarily for the next five months either way. Adapting to better handle the cold makes the winters feel easier on you. I find that I don’t have to bundle up as much when I’ve been consistent with cold plunging or doing contrast therapy and that I can handle going outside with lighter layers.
Fitting This Into Your Actual Week
A few practical notes, because this is the part that turns interest into action.
A sauna session is 30 minutes. Budget about 45 with changing and a shower after. It fits in a lunch break or before dinner.
Wear whatever's comfortable, or nothing; it's a private room. Most people sit on towel. We have everything you need on site.
Hydrate before, not just after. By the end of the thirty minutes you'll sweat more than you expect in a dry infrared heat.
Evening sessions suit winter well. Many people find the drop in body temperature afterward helps them wind down for sleep.
You can add a sauna to a float for $22, which is a good combination when the cold has made you tight and wired at the same time.
FAQs About Our Infrared Sauna
How much does an infrared sauna session cost in Peterborough?
At Flow Spa, a 30-minute individual session is $32 and a couple's session is $44. Packages bring that down to $20 a session, and the Unlimited Membership at $150 a month covers unlimited sauna, float, contrast, and Normatec. Full details are on our pricing page.
How often should I use an infrared sauna?
Most people find once or twice a week is a sustainable rhythm, and the research on sauna benefits generally involves regular use over time rather than one-off sessions. Start with once a week through the fall and see how you feel before adding more.
Is an infrared sauna different from a regular sauna?
Yes. A far infrared sauna warms your body directly using light and ceramic heaters at around 155°F, rather than heating the air to 185°F or higher. Most people find it more comfortable to sit in for longer, and the health effects associated with sauna use come from the heat itself, so they apply to both.
Can I use the sauna and cold plunge together?
Absolutely, and that combination is available as contrast therapy or skip the hot tub and just book the sauna and cold plunge. You can book a 30-minute sauna and cold plunge for $42, or the full contrast room for an hour at $47.
Will the sauna help with seasonal low mood?
Many of our regulars tell us it helps them through the darker months, and warmth, routine, and a half hour away from screens are all reasonable things to have in winter. It isn't a treatment for seasonal depression though. If the winter is hitting you hard, please talk to someone; our psychotherapy team is here for that.
Is the sauna private?
Yes. It's a two-person unit in a private room, so you're either on your own or with whoever you booked it with.
Stay Structured This Winter
You don't need a whole new routine for the cold months. One warm half hour a week, somewhere you don't have to think, is usually enough structure to your routine to keep the season from flattening your motivation.
Book an infrared sauna session to see for yourself, or take a look at the membership options if you already know you'd rather make it a habit than a treat.
