Hot Yoga: Heated Classes Explained

Styles of yoga 3 illustrations Updated 2 Nov 2026

Hot yoga is any yoga class held in a room heated well above normal temperature, often between about 32 and 40 degrees Celsius, sometimes with added humidity. The heat makes muscles feel looser, raises the heart rate and makes you sweat heavily, which many people enjoy as an intense workout.

It also brings real risks, from dehydration to heat illness. This page explains what happens in a hot yoga class, the poses commonly used, possible benefits, who should avoid it, and how to stay safe if you try it.

Room heat: About 32 to 40 degrees Celsius
Class length: 60 to 90 minutes
Style: Fixed sequences or heated flow classes
Main risk: Dehydration and heat illness
Avoid if: Pregnant, heart disease, uncontrolled BP
Bring: Water, towel, electrolyte drink

What is hot yoga?

Hot yoga is not one style but a setting. Some schools teach a fixed series of around 26 poses and two breathing exercises in a room near 40 degrees. Others run heated vinyasa or power yoga classes at slightly lower temperatures. In all of them, the heat adds intensity: you sweat more, your heart works harder, and stretches feel easier, which can tempt people to push too far.

Possible benefits

Studies of heated yoga show improvements in flexibility, balance and some fitness measures, similar to those from yoga at normal temperatures. Many people enjoy the cleansing feeling of sweating and the challenge. However, research has not shown clear extra benefits from the heat itself compared with regular yoga, and the heat adds risk.

Risks of hot yoga

Dehydration from heavy sweating.
Heat exhaustion or heat stroke: dizziness, nausea, headache, confusion.
Overstretching: warm muscles stretch further, but joints and ligaments can be strained.
Low blood pressure and fainting, especially when standing up quickly.

Who should avoid hot yoga

Avoid heated classes in pregnancy, with heart disease, uncontrolled high or low blood pressure, diabetes with poor control, epilepsy, a history of heat illness, or if you are unwell. Older adults and anyone on medicines that affect sweating or heart rate should ask a doctor first. In India's hot months, ordinary room temperature practice already gives plenty of warmth.

Tips if you try it

Drink water through the day before class; avoid a heavy meal.
Bring water, a towel and an electrolyte drink.
Take it easy in your first few classes; rest whenever you need.
Leave the room at any sign of dizziness, nausea or headache.
Do not stretch further than you would in a normal room.

For something calmer, try hatha yoga or browse the different styles.

Wear light, breathable clothing and take a cool shower afterwards rather than an ice cold one.

Practise on an empty stomach, move slowly into each position and stop at any sharp pain. If you have an injury, a health condition or are pregnant, check with a doctor or an experienced teacher first.
