Hot yoga is really popular as an alternative to regular temperature yoga classes. Hot yoga is a studio-based yoga practice in a super-heated room (42 degrees celcius - imagine Egypt in the summer then pour in extra humidity) where the aim is to work through a physical yoga practice and sweat a ton, then lie down and bask in the heat as you recover from the effort. It's intense and many people love it.
Why super heat a yoga class?
The claims about benefits of hot yoga practice are many:
- Detoxes the body
- Sweating is good for you
- Improved flexibility
... and so on.
The science may not back this up, but those who love it feel the results and swear by it. Those who don't love it, probably never go back.
I fall into the latter camp and find the claims to be subjective but if it benefits you and you enjoy it, then keep doing it.
As with all physical yoga practices, be cautious not to over stretch and be particularly careful with your joints, that they stay within a safe and comfortable range of motion. I have had many injured hot yoga practitioners come with knee, elbow and shoulder injuries from hot yoga classes so go carefully. Sometimes when the heat is on and the practice is intense, it is hard to listen to the inner voice advising you to ease off. Hot yoga can get competitive and that makes it harder to draw back from a pose when necessary. So applying your own sensible body-awareness skills to your practice is paramount when the heat intensity is turned up.
Is it more beneficial than not-hot yoga?
I'm biased, as I've been practicing yoga for 20 years and find an ambient room or even a cool space a wonderful way to practice. I can engage fully in my yoga practice when I'm able to turn the attention inwards rather than feeling overly hot or sweaty. I tend to heat up during my practice anyway, even if just taking a breathing (pranayama) practice.
I recently came across an interesting thesis which undertook a study comparing hot yoga practitioners alongside regular temperature Hatha yoga practitioners. The aim was to measure the effects of yoga practice on physiological and psychological fitness in young men and women over an 8-week period. Health metrics that were monitored include BMI, blood pressure, flexibility, peak oxygen consumption, back depression, anxiety and depression metrics.
Hot yoga participants worked at a significantly higher cardiovascular intensity and spent more time at a higher heart rate throughout the classes. But even with this, over the 8-week period, both hot yoga and Hatha yoga groups saw the same improvements in body composition and flexibility and also in anxiety and depression scores. So the outcome observations suggest that there are real, significant health benefits to engaging in both forms of yoga practice but there was no final measure on any additional psychological or physiological benefits gained by hot yoga training.
So by all means, do hot yoga practice if you love it and feel no ill effects from it, but from what we can tell, the health benefits are not greater doing it in a hot and sweaty room.

Home yoga practice?
I'm a big advocate of home yoga practice. Little and often can often bring about the most benefit - it is free to everyone and has an intimacy to it that you rarely get in the classroom. Ask any of my students who get a free home yoga practice handout at the end of each term to go and try at home. So learning your yoga practice skills in a group class or with personal yoga tuition and then starting to apply those skills in your home practice is a wonderful way to practice yoga. I've written about home yoga practice before here.
One of the limiting factors to hot yoga practice is that you have to go to the studio regularly to do this, and the costs add up. (Don't get me started on Mr Bikram, the hot yoga business mogul and his exuberant love of money and Rolls Royces - as a business model he turned hot yoga into a money spinner). Of course the communities that develop around group classes are wonderful and valuable, but the tie in to the studio and the costs involved can become problematic.
What about subtlety in yoga practice?
Beyond the intense physicality of the hot yoga class, also remember there is an inner essence to yoga practice. The internal connection through body, breath and mental focusing that go beyond the measurable health metrics outlined in the comparative study. I'm not sure the subtlety of my pranayama or meditation practice would be possible in an intensely heated environment yet the crown of my yoga practice can often be found here (thus my bias to comfortable temperature practice). My inner meditative focus might be externally drawn to feeling overly hot or to the physical sensations of sweating. But I get that some folks need the intensity of a very physical practice to keep them focused out of their busy minds.
I guess my final thought is that usually any yoga practice is better than no practice - so ultimately do whatever is likely to motivate you and do what you you will enjoy.
