Key points
- Hot yoga is defined by the heated room: styles, sequences, and temperatures vary significantly by studio.
- Bikram is 26 postures at 40°C for 90 minutes; hot vinyasa is a flowing class with a changing sequence.
- Hydrate well before class: many teachers limit mid-class drinking to designated breaks, so follow the studio's protocol.
- Talk to your GP first if you have cardiovascular issues, high blood pressure, or take medication that affects heat tolerance.
Why heat?
Proponents say a heated room loosens muscles for deeper stretching and produces a cardiovascular effect similar to mild aerobic exercise. The research on whether the heat specifically improves flexibility beyond a non-heated class is mixed, and strong claims about detoxification through sweating are not supported by physiology. Sweat removes water, salts, and trace minerals, not toxins.
What the heat reliably does is make the class feel harder. Your heart rate runs higher than it would from the same moves at room temperature, and you will sweat a lot more. That experience is the appeal for a lot of people who choose hot yoga. If you like that intensity, it is genuinely useful. If you run hot, find heat distressing, or have any cardiovascular concern, it adds a layer of risk that warrants a conversation with your GP first.
The main styles
Hot yoga is not a single style. The heated room is the format, and several distinct practices take place inside it.
<table> <thead> <tr> <th>Style</th> <th>Temperature</th> <th>Length</th> <th>Sequence</th> <th>Best for</th> </tr> </thead> <tbody> <tr> <td>Bikram</td> <td>40°C / 40% humidity</td> <td>90 min</td> <td>26 postures (24 asanas + 2 breathing)</td> <td>People who want structure and benchmarking</td> </tr> <tr> <td>Hot vinyasa</td> <td>32 to 37°C (varies)</td> <td>60 to 75 min</td> <td>Changing, teacher-designed flow</td> <td>People who prefer variety in a heated environment</td> </tr> <tr> <td>Hot yin</td> <td>28 to 35°C (milder)</td> <td>60 to 75 min</td> <td>Long-held floor poses</td> <td>Flexibility and relaxation with gentle warmth</td> </tr> <tr> <td>Infrared hot yoga</td> <td>35 to 38°C</td> <td>60 min</td> <td>Varies by studio</td> <td>People who find traditional heat too heavy</td> </tr> </tbody> </table>The temperature at each studio can vary from its marketing. If you are sensitive to heat, ask the specific room temperature before you book. Curious about the unheated versions? The vinyasa yoga guide and the yin yoga guide cover those styles at room temperature.
What a class feels like
You will probably sweat more than you expect. A lot of first-timers are caught off guard by how much, and by the way the heat throws off their balance and wears them down faster. Poses that feel easy at room temperature become genuinely taxing.
The standard advice is to spend your first class just acclimatising. Lie down on your mat if you need to. Step out of the room if you feel dizzy or nauseous. These are sensible precautions, not signs of failure.
Bring a full water bottle and a towel. Most studios require a towel over the mat because the sweat volume makes grip impractical without one. Some teachers ask you not to drink water until a designated break, which is a traditional approach, so follow the studio's protocol.
Who it suits and who should check first
Hot yoga suits people who enjoy intensity, warmth, and a physical challenge. It is also worth trying if you are someone who is always cold and struggles to warm up in a normal class.
Some people should check with a GP or physiotherapist before attending. Cardiovascular conditions, high blood pressure, pregnancy, epilepsy, heat intolerance, and medications that affect sweating or blood pressure are all reasons to seek personalised advice first. healthdirect, Australia's national health service, notes that people with high blood pressure or heart problems should talk to their GP before attempting hot yoga or Bikram yoga.
If you are healthy and want to try it, an intro offer at a reputable studio is the lowest-risk way in. And if you have never done yoga at all, the first yoga class guide makes the case for starting in an unheated class before adding the heat.
What it costs in Australia
Heated yoga tends to price slightly higher than unheated styles because the studio pays to run the heating. Casual hot yoga classes in Australia typically run $25 to $40. Two-week unlimited intro offers commonly sit around $50 to $80.
Class packs of 5 or 10 usually save around 15 to 25% compared to casual pricing. Unlimited memberships for heated yoga studios often run $200 to $300 a month.

Hot Yoga: common questions
- Is hot yoga safe for beginners?
It can be, with a few precautions. Arrive well hydrated, do not eat heavily before class, bring a towel, and give yourself permission to rest or leave the room if you feel unwell. Tell the instructor it is your first class. If you have any cardiovascular condition, high blood pressure, or are pregnant, check with your GP first.
- What is the difference between Bikram and hot yoga?
Bikram is a specific style of hot yoga: 26 fixed postures and 2 breathing exercises in a 40°C room for exactly 90 minutes. Hot yoga is the broader category: any yoga class in a heated room. A hot vinyasa class is also hot yoga, but it is nothing like Bikram.
- Will I lose weight doing hot yoga?
The sweating you do in a hot yoga class is water loss, not fat loss. Your weight on the scale will drop after class and return when you rehydrate. Hot yoga does burn more calories than the same poses at room temperature because your heart is working harder, but the extra burn is not much more than you would get from moderate aerobic exercise. Weight change is driven by overall activity and nutrition, not by one class type.
