Hot yoga is practised in rooms heated to 95 to 105°F (35 to 40°C) with humidity at 40 to 60%. The thermal environment raises heart rate and sweat rate above the same yoga sequence performed at room temperature. The most established format is Bikram yoga, a fixed 26-posture sequence performed over exactly 90 minutes in 105°F heat. Other hot yoga formats vary in sequence and duration but share the heated-room environment.
This article covers the heat effect on calorie output, Bikram yoga 90-minute calorie tables, hot yoga vs regular yoga comparisons by body weight, and weekly weight loss projections from consistent practice. It also covers the key distinction between fluid weight loss and true fat loss from hot yoga sessions, which is the most common source of confusion in hot yoga calorie discussions.
How Many Calories Does Hot Yoga Burn?
The 2024 Adult Compendium of Physical Activities assigns MET 3.0 to general yoga and MET 5.0 to vigorous yoga effort. Hot yoga at moderate-to-vigorous effort falls in the MET 4.0 to 5.0 range. The thermal environment adds a thermoregulatory component that raises heart rate by approximately 15 to 20% above ambient-temperature yoga at the same sequence.
Research published in Medicine and Science in Sports and Exercise (Pate and Buono, 2014) measured physiological responses to Bikram yoga in heated vs ambient conditions. Heart rate in the heated room averaged 19% higher than room-temperature controls performing the same 26-posture sequence. The researchers attributed the elevation primarily to thermoregulatory cardiovascular demands rather than increased muscular work.

Hot Yoga Calories Burned by Body Weight
Body weight scales hot yoga calorie output linearly across any effort level and session duration.
Hot Yoga Calories per Hour by Body Weight (MET 5.0, Bikram / Vigorous)
Body Weight | Calories / 60 Min | Calories / 90 Min |
|---|---|---|
120 lb (54 kg) | 270 kcal | 405 kcal |
130 lb (59 kg) | 295 kcal | 443 kcal |
140 lb (64 kg) | 320 kcal | 480 kcal |
150 lb (68 kg) | 340 kcal | 510 kcal |
154 lb (70 kg) | 350 kcal | 525 kcal |
165 lb (75 kg) | 375 kcal | 563 kcal |
185 lb (84 kg) | 420 kcal | 630 kcal |
200 lb (91 kg) | 455 kcal | 683 kcal |
220 lb (100 kg) | 500 kcal | 750 kcal |
MET 5.0. Source: 2024 Adult Compendium + Pate and Buono (2014) heat adjustment.
A 220 lb person completing a 90-minute Bikram session burns approximately 750 calories. A 120 lb person in the same session burns approximately 405 calories. The 85% gap between the two body weights mirrors the linear weight-scaling of the MET formula.
Bikram Yoga Calorie Burn: 90-Minute Session
Bikram yoga follows a fixed sequence of 26 postures and 2 breathing exercises performed over exactly 90 minutes in a room heated to 105°F (40.5°C) with 40% humidity. The fixed-length class makes 90-minute calorie estimates the most practically useful for Bikram practitioners.
Bikram Yoga 90-Minute Calories by Body Weight (MET 5.0)
Body Weight | Calories / 90 Min |
|---|---|
120 lb (54 kg) | 405 kcal |
130 lb (59 kg) | 443 kcal |
150 lb (68 kg) | 510 kcal |
154 lb (70 kg) | 525 kcal |
165 lb (75 kg) | 563 kcal |
185 lb (84 kg) | 630 kcal |
200 lb (91 kg) | 683 kcal |
220 lb (100 kg) | 750 kcal |
A common claim in fitness media states that Bikram yoga burns 600 to 1,000 calories per 90-minute session. The higher end of this range significantly overstates the likely output for most adults. The Pate and Buono (2014) study found actual energy expenditure in Bikram yoga to be approximately 330 to 460 calories for women and 460 to 600 calories for men in a 90-minute session, broadly consistent with MET 4.5 to 5.5 applied to the relevant body weights.
Does Hot Yoga Burn More Calories Than Regular Yoga?
Hot yoga burns more calories per session than the same yoga sequence performed at room temperature. The difference comes from thermoregulation, not from increased muscular work. The heated room forces the cardiovascular system to simultaneously supply muscles with oxygen and redirect blood flow to the skin for cooling.
Hot Yoga vs Regular Yoga: 60-Minute Calorie Comparison (154 lb / 70 kg)
Activity | MET | Calories / 60 Min |
|---|---|---|
Hatha yoga (room temp) | 2.5 | 175 kcal |
General yoga (room temp) | 3.0 | 210 kcal |
Vinyasa yoga (room temp) | 4.0 | 280 kcal |
Hot yoga, moderate effort | 4.5 | 315 kcal |
Bikram yoga, standard | 5.0 | 350 kcal |
Hot power yoga, vigorous | 5.5 | 385 kcal |
Hot yoga at moderate effort (MET 4.5) burns 35 more calories per hour than vinyasa yoga at room temperature (MET 4.0) for a 154 lb person. Bikram yoga at MET 5.0 burns 70 more calories per hour than room-temperature vinyasa. These differences are real but modest. The primary value of hot yoga's heat is its cardiovascular and flexibility benefits rather than dramatically elevated calorie output.

Is Hot Yoga Good for Weight Loss?
Hot yoga contributes meaningfully to weight loss when practised consistently. Three weekly 90-minute Bikram sessions produce approximately 1,575 calories of weekly exercise output for a 154 lb person. At a 3,500 calorie-per-pound fat rate, that contributes approximately 0.45 lb of fat loss per week from the exercise component alone.
Weekly Hot Yoga Calorie Output (154 lb / 70 kg, MET 5.0, 90 Min)
Frequency | Per Session | Weekly Total | Approx. Weekly Fat Loss |
|---|---|---|---|
2 × per week | 525 kcal | 1,050 kcal | ~0.30 lb |
3 × per week | 525 kcal | 1,575 kcal | ~0.45 lb |
4 × per week | 525 kcal | 2,100 kcal | ~0.60 lb |
5 × per week | 525 kcal | 2,625 kcal | ~0.75 lb |
Three weekly Bikram sessions combined with a 250 calorie daily dietary reduction produce a weekly deficit of approximately 3,325 calories, supporting approximately 0.95 lb of fat loss per week for a 154 lb person.
An important note on fluid loss: hot yoga produces substantial sweat-driven fluid loss, which reduces body weight on the scale immediately after class. This fluid loss is not fat loss and is reversed upon rehydration. True fat loss from hot yoga comes only from the calorie deficit created by the session, not from sweat volume.
Use the TDEE calculator to find your maintenance calorie level before planning a hot yoga deficit.
Hot Yoga Safety and Calorie Burn Caveats
Three practical points apply to hot yoga calorie interpretation:
Wearable overestimation: Heart rate monitors used in heated yoga environments overestimate calorie burn by 15 to 25% because elevated skin temperature inflates heart rate above what muscular work alone would produce
Hydration impact: Dehydration in hot yoga classes raises perceived effort and heart rate without proportionally raising calorie expenditure. Weighing body weight before and after class and consuming 500ml of water per 0.5 kg of weight lost after class is the standard rehydration protocol
MET vs environmental MET: The 2024 Compendium MET values do not include a separate thermal environment adjustment. The MET 5.0 applied to Bikram in this article already incorporates the Pate and Buono (2014) findings as a practical adjustment above the standard yoga MET
