Summer Sauna Secrets
Turning Up the Heat in July: Why You Should Sauna This Summer
(And How to Do It on Your Own Terms)
It sounds entirely counterintuitive. Why on earth would you want to willingly step into a box that’s 170–180°F when it's already a scorching 100°F outside?
Your first instinct in July is probably to dive straight into a cold plunge or hide in the AC. But turning down the heat on your sauna routine during the summer means missing out on some of the best cellular and mental resets of the year.
Let's talk about why summer sauna sessions hit different, debunk some of the rigid "rules" floating around the internet, and look at how to build an intuitive, low-tox practice that actually honors your body.
The Summer Secret: External Heat vs. Internal Heat
Getting hot from sitting out in the sun is completely different from heating your body up from the inside out. Ambient summer heat causes superficial sweating—it's your body's baseline mechanism to keep you from overheating.
A proper sauna session, however, triggers a deep, core-temperature rise. This internal heat dilation yields massive health benefits that a hot day in Texas simply can't replicate:
Deep Cellular Detox: It forces a heavy, purifying sweat that flushes out deep-seated waste from your pores.
Heat Shock Proteins: It stimulates these special proteins, which act like a cleanup crew to repair damaged cellular structures and protect against muscle loss.
A Cardio Workout: Your heart rate elevates, blood flow surges, and your cardiovascular system gets a workout—all while you're sitting completely still.
So don't put your routine on pause just because it's July. Turn up the heat, get sweaty, and follow it up with a cold shower or plunge for the ultimate summer contrast therapy reset.
Traditional vs. Infrared: Why the "True Heat" Wins
When looking into upgrades or figuring out the best way to sweat, you have to weigh the options between infrared cabins and traditional heat. There is a lot of marketing buzz around infrared saunas right now, but if you want a true, traditional Finnish experience, nothing beats a regular heat source like a wood-fired or electric stove.
Infrared saunas compete by using light waves to heat your body directly from the inside out, rather than heating the air around you. Because of this, they run much cooler—usually around 130°F to 140°F—which is great for people who can't tolerate breathing in heavy, hot air.
Traditional saunas, however, heat the ambient air to intense temperatures between 175°F and 210°F. According to podcasters like Dr. Andrew Huberman, most clinical studies showcasing the massive cardiovascular and longevity benefits of sauna were actually done using traditional, high-heat Finnish setups. Traditional heat creates a true thermal load on the body, triggering an immediate cardiovascular workout that infrared struggles to replicate in the same timeframe.
Keep the Red Light Separate
You might also see infrared cabins boasting built-in red light therapy, but it is actually best to keep your red light separate from a good sweat session. Red light therapy works best on clean, cool, dry skin. When you are pouring sweat, the moisture layer on your skin can refract and scatter the light waves, preventing them from penetrating properly. Keep your red light sessions as a separate ritual, and let your sauna time be about pure, raw heat.
Ditch the "Sauna Police" (Listen to Your Body)
If you spend five minutes on health Twitter or wellness podcasts, you’ll find endless "experts" screaming about the exact math of sauna therapy. They’ll tell you that if you aren't doing precisely 20 minutes at 174.5 four times a week, you're doing it wrong.
Sure, there is great science out there. But truthfully? I am here to help guide you on how to listen to your own body, not a stopwatch. Some days your nervous system is primed for a long, hot, deep sweat. Other days, your body is tired, and 10 minutes is all it wants. Both are a win. Don't let rigid optimization ruin a practice meant to bring you back to center. Drop the data obsession, step inside, and tune into how you feel.
When it comes to the actual session, you don’t need to obsess over a thermometer to know if you are doing it right. Let's look at this intuitively: honestly, if you are sweating heavily and you feel like your heart is pumping—almost like you are getting some solid cardiovascular work—that is great. You are in the sweet spot.
Instead of watching the clock perfectly, you can gauge truly when you are ready to come out by listening to your body, though there is a fascinating scientific scale to how the benefits stack the longer you are under deliberate heat stress.
In the first five to ten minutes, your body triggers a mild stress response that actually paves the way for a massive release of endorphins afterward, giving you that blissful sauna high and a sharp drop in mental stress. By the twelve to fifteen-minute mark, your blood vessels dilate, your heart rate spikes, and you achieve that true cardiovascular workout that mimics a moderate jog, flushing your system and improving circulation. If you can safely push to twenty minutes, the intense heat stress triggers a massive spike in growth hormone, which is incredible for muscle recovery, cellular repair, and metabolism.
The Digital Detox: A True Mental Sanctuary
Beyond the physiological gains, the sauna has become my ultimate mental sanctuary for one simple reason: it is a forced space without phones. In a world where we are constantly bombarded by notifications, emails, and dopamine loops, the sauna is a strict electronics-free zone (unless you want your phone to overheat and fry!). When you step inside, it is just you, your thoughts, your breathing, and maybe some soft, meditative music playing in the background. It provides the literal and figurative space to breathe, ground yourself, and set intentions for the day or week ahead. It’s as much a brain reset as it is a body reset.
A Quick Cyclical Note: I also absolutely love saunaing during my menstrual cycle. There is something so incredibly cozy and comforting about the deep warmth. Plus, from a purely functional standpoint, it does wonders for relieving cramps, releasing water retention, and melting away that stubborn hormonal bloating.
The Low-Tox Sauna Wardrobe: What to Wear (and Avoid)
When you heat your body up to extreme temperatures, your pores open completely wide. Your skin becomes a massive sponge. This is why what you wear inside the sauna matters just as much as the temperature itself.
Most people throw on a standard synthetic bathing suit or gym clothes, but here is why you want to ditch them:
1. Say No to Polyester and Plastics
Standard activewear and modern bathing suits are loaded with polyester, nylon, and synthetic materials. When subjected to high heat, these synthetic fibers can off-gas and leach microplastics or chemical dyes directly onto your hot, open pores. You are trying to detoxify, not absorb melted plastic.
2. The Organic Robe or Turkish Cotton Towel Alternative
Instead, opt for a simple cotton robe or towel or a high-quality, organic Turkish cotton robe like I have here. Going wrapped in raw, natural fibers allows your body to breathe fully and feel free. Even better? The cotton acts as a barrier, instantly soaking up the toxin-laden sweat your body is working so hard to remove, rather than letting it pool on your skin and reabsorb.
Tip: If you’re heading straight to the sauna after the gym, try to plan your sessions for days you’re wearing natural fibers. For a great, non-toxic workout brand, check out Allwear and use code BAE20 for a discount!
3. The Secret Weapon: The Wool Sauna Hat
If you've ever seen someone wearing a funny-looking felt hat in a sauna and wondered why, they're ahead of the game. A traditional wool or thick cotton sauna hat is a game-changer.
Temperature Balance: Your head heats up much faster than the rest of your body. The hat acts as an insulator, keeping your head at a balanced temperature so you don't feel dizzy or have to "throw in the towel" early before your core gets its full sweat.
Hair Protection: Extreme heat can severely bake, dry out, and damage your hair strands. The hat protects your crown and keeps your hair healthy and hydrated.
Timing: When is the Best Time to Sweat?
You might have heard podcasters like Andrew Huberman dive deep into the circadian science of temperature. Scientifically speaking, the evening is an incredible time to sauna. While the intense heat drastically spikes your growth hormone levels, the magic for sleep happens right after: to fall asleep, your core body temperature needs to drop by about 1 to 2 degrees. When you step out of a hot sauna, your body triggers a rapid, internal cooling mechanism that brings your temperature down, perfectly setting the stage for deep, restful sleep.
But again—let's look at the bigger picture. If your schedule only allows for a mid-day session or a morning sweat to kickstart your circulation, do it anyway. A morning sweat is wonderful for mental clarity and waking up the nervous system. Don't skip a healthy habit just because the timing isn't "perfect."
Affordable Consistency: My Journey from Blankets to Tents
At the end of the day, consistency is everything. The best wellness routine is the one you actually show up for. Going to high-end wellness clinics or commercial spas can get incredibly pricey, and those costs add up fast if you're trying to make this a frequent habit.
To keep things consistent at home, I used a Bon Charge sauna blanket for four years. It absolutely did the job, and I loved it for a long time! But I had been eyeing an upgrade for a while—something that offered a true, immersive, full-body experience without costing tens of thousands of dollars. I wanted to move away from laying down in a blanket that felt a bit too temporary, and find a setup where I could actually move around. Then enter SweatTent. While it’s not exactly a traditional wooden cabin, it gave me exactly what I was looking for: a high-heat, freestanding space where I could sit, stretch, and breathe.
Here is why I'm obsessed with this portable powerhouse:
Zero VOCs & Non-Toxic Construction: Unlike cheap Amazon knock-offs that smell like burning chemical plastic when they heat up, the SweatTent is built with high-quality, non-toxic, insulated Oxford 210D fabrics. It is fully tested up to its peak 200°F temperature to ensure absolutely zero off-gassing or volatile organic compounds (VOCs) are released into the air while you're breathing deep in that high heat.
Zero EMFs: Because it uses a traditional, heavy-duty stainless steel wood-burning stove rather than an electrical grid, you get an all-natural sweat with absolutely zero EMF exposure.
Insane Heat Output: This thing isn't playing around. It pops up in minutes and can hit a roaring 200°F in under half an hour. You can use it as a completely dry sauna, or pour water over the included sauna rocks for that authentic, heavy Scandinavian steam.
It gives you the raw power and luxury of a commercial Finnish sauna right in your backyard, at a fraction of the cost of a permanent wooden build. If you want to check it out, you can explore the Sauna Tent HERE and use my code LINDSAY10 to save a bit of cash!
Final Thoughts
Saunaing in the summer isn't crazy—it's highly effective. Just remember to keep it clean, keep it simple, and keep it intuitive. Wrap yourself in some pure cotton, pop on a sauna hat, leave your phone inside the house, and listen to your internal gauge. Your body (and your mind) will thank you!
