The main difference between hot yoga and regular yoga is the temperature and humidity level in the room. Hot yoga classes at Altea Active take place in a studio with a temperature of 105 degrees (40 degrees Celsius) and 40% humidity. Regular yoga classes take plan in our Fusion studio, which is at room temperature. Hot yoga classes are generally more intense, due to the heat and humidity. It’s important to drink plenty of water in hot yoga classes to stay hydrated.
