Why Your Body Temperature and Environment Matter More Than You Think

I just got back from a trip to the U.S., where a huge winter storm swept through half the country. Some days, the highs were still well below freezing. When it's the middle of winter, and there's a cold front, I like to either:

• do an intense Vinyasa Flow class to build internal heat, or

• lay around and be as comfy and cozy (and lazy!) as possible

Here was my latest yoga outfit - see if you can guess which kind of practice I picked:

• thick sweater

• gloves

• warm hat

• two pairs of socks

• And the biggest, thickest sweatpants I own.

Not the sexiest yoga outfit, that's for sure. And not practical at all for a Hatha or Vinyasa Flow. But for my Restorative Yoga practice, it was exactly right. And yes, it's the middle of winter, but my summer Restorative outfit isn't that much different, to be honest.

When it comes to Restorative Yoga, environmental design - including what you wear - is a really important part of the setup, especially when your town is hit by subarctic temperatures. When your body and nervous system feel warm, safe and comfy, your body can get into parasympathetic mode; the rest-and-digest state yoga helps us achieve. Discomfort, environmental triggers, and cold ramp up our fight-or-flight mode and trigger tension as a protective mechanism. Physiologically, your body can't relax when it feels uneasy or cold.

So although you generally don't need much for your yoga practice, when it comes to Restorative Yoga, you need not just a mountain of props, but a mountain of warm clothes, too - especially in winter. Beyond the poses themselves, dressing warm and setting your room up in a way that supports deep release is a necessity for a successful practice.

The Science of Warmth: How Temperature Affects Your Practice

Why You Need To Be Warm

Cold muscles tense up to generate heat. When your muscles tense, your sympathetic nervous system (fight-flight-freeze...literally :)) ramps up. This is a survival response that your body can't override through willpower, unless you're Wim Hof. So even if you really try to relax your muscles when you're cold, they won't stop contracting, as their job is to create heat when the body is cold.

In active yoga styles like Vinyasa Flow or in a strong Hatha class, movement generates internal heat, so muscles can easily relax in passive poses like Savasana.

In Restorative, any muscular tension - even just the slight tension created by muscles that are cold - defeats the purpose of the practice, which is to get into the parasympathetic state.

Practical Temperature Solutions

Layer your clothing aggressively. Wear fuzzy sweaters, long sleeves, and multiple pairs of socks. What feels slightly too warm at the beginning will feel right after ten minutes of stillness.

Grab two extra blankets in the winter, especially, and use your blankets strategically. Instead of just using them to prop up joints, place one blanket under your body and one over it during longer holds, no matter the pose. The blanket underneath provides cushioning and warmth from below, and the blanket on top prevents heat loss. Alternatively, practicing on carpeting or a thick rug works, too.

Adjust room temperature a few minutes before your practice begins. I have the European-style heating knobs for each room in my house, and I turn them up one level about 20 minutes before my Restorative practice. You might adjust your thermostat if you have whole-house heating, but if you'd rather save energy, you might try plugging in a warming humidifier in a closed room, instead - some of them can up the room temperature by almost 10 degrees! The key is to have a nice toasty practice space, if possible, as waiting until you're cold is too late - your muscles will be tense and you'll probably be stuck in a sympathetic state.

If you're teaching Restorative classes, set the studio temperature three to five degrees warmer than you would for active classes.

Gathering Your Props

Essential Props and Creative Alternatives

The standard Restorative toolkit includes two blocks, one strap, two bolsters (if possible), and two blankets. But you don't need to buy expensive yoga props to practice effectively at home.

When I teach Restorative online, I tell students to gather whatever they have - pillows, blankets, towels, kleenex boxes, animals, boyfriends, girlfriends, etc. We'll figure out a way to use it.

Bolsters can be firm couch cushions, bed pillows, or rolled sleeping bags. Blocks can be hardcover books or sturdy boxes. Straps can be belts, ties, or resistance bands. Blankets can be towels, throws, or comforters.

The principle matters more than the equipment. Support and comfort are the goals.

Beyond Props: Other Environmental Factors

Lighting Considerations

Have you ever heard that animals often give birth at night? Or that they seek out dark caves or the darkness of thick foliage to give birth? It's because giving birth goes faster and works better in the rest and digest state. Bright light, and especially synthetic indoor lighting, signals the nervous system to be on-guard and alert. Dimming or turn off harsh lights will help you get into your parasympathetic state. If you want to have some light (if darkness puts you immediately to sleep!), natural light is ideal, but avoid direct sunlight that creates heat spots on the body. Candles or salt lamps provide gentle ambient light that supports relaxation.

For evening practice, warm-toned lighting - yellow or orange - is preferable to cool-toned blue or white.

Sound and Silence

After touch, sound is the second sense we develop in the womb. As an embryo, the sound of gentle fluid dynamics and your mother's heartbeat played a huge role in your earliest experiences. Even now as an adult, the sound of a heartbeat, or white noise (similar to the sounds in the womb) have a relaxing effect for most people. Unexpected sounds, on the other hand, trigger the startle response which brings the nervous system into fight or flight. Create a quiet environment or use consistent background sound to allow yourself to go deep into relaxation.

Nature sounds or gentle music can mask unpredictable environmental noise. Silence is also powerful but only if it's truly quiet, as struggling to ignore sounds prevents us from releasing. If you hear cars, sirens, construction, or your roommate watching a movie in the next room, masking those sounds with calming music will really help you settle in to your practice and relax.

I always encourage my 200 hour YTT students to only play neutral, instrumental music when they teach Restorative Yoga, rather than popular music with words. There are a few reasons for this:

• First, words trigger us to think - we process what is being said. This prevents us from going from our normal state of alertness into deep relaxation.

• Secondly, we might have a negative reaction to the lyrics or the song itself - especially if it's a song we know and dislike. This will definitely prevent us from relaxing, triggers our fight or flight response, and even causes us to frown and grimace (I love that there is research on this :)). I went to a Restorative class one time where the teacher played slow R&B with lyrics. I would've liked the music in a different setting - a coffee shop or restaurant, for example - but it prevented me from getting into a deeper state of awareness.

So, especially if you're teaching, be really mindful of your music choices. That being said, it's fair to say that you will probably never have a day when every single person in the room is 100% happy with the music you play.

And one more note on teaching Restorative Yoga - you may want to warn students before using singing bowls or other sounds during deep relaxation. And to be honest, I usually forget to do this before I start class! So I do my best to very quietly introduce the singing bowls each time I use them (typically to bring students out of a pose).

Using Scent

The smell of sandalwood never fails to take me back to wonderful times I've had in India. Palo Santo reminds me of incredible trips I've taken to South America. Scent can often create positive emotions and help you relax.

However, scent can also have negative effects. Strong scents, even pleasant ones, can be distracting or triggering when you practice Restorative yoga. As an example, I have a lovely lavender eye mask I got as a gift one time from a student. And even though I absolutely love(!) the smell of lavender, it's too much for me during practice, as the smell is really strong so close to my nose.

For your home Restorative practice, you might want to use essential oils or a bit of incense to create some olfactory magic for your time on the mat.

As a teacher, I used to burn incense in every class I taught, and had oils at the front of the room for students to use if they wanted.

But just a word of warning about scent if you're a yoga teacher who uses it in class - more people are allergic to scent than you might think. My mom became allergic to any and all scents - natural and synthetic - after going through chemotherapy. There will be others who are allergic to anything artificial, like candle scent or incense. And others might not be allergic to it, but might not like the same scents as you do.

My advice, even though I personally love using scent in small ways when I practice at home, is to use scent sparingly. And if you really want to make sure no one has a negative reaction to scent in your class, don't use it at all. (I still love to light up some Palo Santo during Savasana, especially with the windows cracked for a few minutes for air circulation - then it's not too overwhelming).

Seasonal Adaptations for Year-Round Practice

Winter Practice Adjustments

Increase layers significantly. What feels too warm at the start will feel right after a couple minutes of stillness.

Preheat the practice space fifteen to twenty minutes before beginning. Use heavier blankets like fleece or wool instead of cotton if you can. Consider heated blankets or heating pads for longer holds for an extra luxurious winter practice!

Practice on thick rugs or blankets rather than a cold floor.

Notice Your Environment First, So You Can Forget It Later

Building Environmental Awareness in Winter

Pay attention in the first minutes of your practice, and teach students to notice: Am I tensing because I'm cold? Am I lifting any body parts off the floor to try and stay warm?

Each point of tension indicates a need for adjustment - either adding a layer of clothing, creating a different prop placement, or taking a full-on position change to allow for full relaxation.

Comfort as a Practice, Not an Afterthought

Creating a supportive environment is not separate from the Restorative Yoga practice. It's actually a huge part of the practice.

The nervous system reacts to cold and environmental stressors like bright lights and loud music in the same was as it reacts to danger. It has a hard time distinguishing between the two, and both trigger protective tension throughout the body and mind - the opposite of what we want from our practice.

Intentional environmental design communicates safety to our nervous system, allowing the profound benefits of this passive practice of long-held poses to shine through.

Whether teaching or practicing at home, remember: genuine warmth and comfort is the foundation of genuine release. Happy practicing!!
