Hot yoga has a loyal following and a fair number of skeptics, often in equal measure. Here's the honest breakdown of how it actually differs from a regular class, so you can decide which one suits your body and your goals.
What Makes Hot Yoga "Hot"
Hot yoga is practised in a studio heated to somewhere between 32°C and 40°C, frequently with raised humidity as well. Bikram yoga, one of the original hot yoga styles, follows a fixed sequence of 26 poses in a room heated to around 40°C. Other styles, sometimes just called "hot vinyasa" or "hot power yoga," apply heat to a more varied, flowing sequence.
Regular yoga classes are held at normal room temperature, with no added heat or humidity — the intensity comes purely from the poses and pace, not the environment.
Hot Yoga vs. Regular Yoga: How the Experience Differs
The most obvious difference is how much you sweat — hot yoga classes are intense in a way regular yoga simply isn't, purely because of the heat. Many people find the warmth helps muscles loosen more easily, making certain stretches feel more accessible. Others find the heat genuinely uncomfortable and prefer a cooler room where they can focus purely on the poses.
A 2025 systematic review covering 43 studies and over 900 participants found that hot yoga reliably raises body temperature and heart rate during a session, but doesn't necessarily increase the actual energetic demand compared to non-heated yoga — in other words, the heat makes a session feel harder without it always being a tougher workout in physiological terms. The same review noted that much of the existing research has methodological limitations, so it's worth treating specific health claims about hot yoga with some caution. You can read the review via PubMed.
Hot yoga also demands more attention to hydration. It's common advice to drink extra water in the hours before a hot class and to bring a water bottle and a towel, since sweating is significantly heavier than in a standard class.
- Hot yoga: heated room (32–40°C), heavier sweating, more hydration needed
- Regular yoga: room temperature, more accessible for heat-sensitive people
- Hot yoga can feel more intense and physically demanding overall
- Regular yoga is usually the better starting point for complete beginners
Who Should (and Shouldn't) Try Hot Yoga
Hot yoga isn't recommended for people who are pregnant, who have certain cardiovascular conditions, or who are prone to dehydration or heat exhaustion. If you're generally healthy and curious about the format, it's worth trying — but ease in gradually rather than committing to a long heated session on your very first attempt.
If you haven't been to any yoga class yet, our guide to your first class is worth reading first — it covers what to expect generally, before adding heat into the mix.
"Neither hot nor regular yoga is objectively 'better' — the right choice depends entirely on how your body responds to heat and what you want from the practice."
Trying Hot and Regular Yoga Before Deciding
If you're undecided, the simplest approach is to try a regular class first to learn the basics comfortably, then try a hot class once you're confident with the poses. Comparing the two directly, rather than reading about them, is the most reliable way to know which suits you. If style differences beyond heat also interest you, our guide to yoga styles covers the rest of the landscape.

A Plain-English Guide to Yoga StylesFrequently Asked Questions
Most hot yoga studios are heated to somewhere between 32°C and 40°C, often with added humidity. The exact temperature varies by studio and style, so it's worth asking before your first class if you're heat-sensitive.
Hot yoga tends to burn somewhat more calories due to the added cardiovascular demand of exercising in heat, but the difference is modest, and most of the immediate weight change you feel afterward is water loss through sweat, not fat loss.
Hot yoga isn't recommended for people who are pregnant, have certain heart conditions, or are prone to dehydration or heat-related illness. If you're unsure, check with a doctor before trying a heated class.
Most instructors recommend starting with regular yoga first, so you can learn proper form and breathing without the added challenge of heat. Once comfortable with the basics, hot yoga is a reasonable next step if it appeals to you.
