The ideal ambient temperature for practicing yoga can vary depending on the type of yoga and personal preference, but a general recommendation is a room temperature between 68 to 72 degrees Fahrenheit (20 to 22 degrees Celsius). This temperature range is believed to help maintain a comfortable level of warmth without overheating, allowing for optimal muscle flexibility and preventing the body from becoming too cool during slower, more meditative practices.

Hot yoga or Bikram yoga practices typically require higher room temperatures of around 105 degrees Fahrenheit (40 degrees Celsius), with substantial humidity to promote profuse sweating which proponents believe aids in detoxification and flexibility. However, such extreme temperatures are not suitable for everyone and can pose health risks like heat exhaustion or dehydration.

Cooler temperatures might be more appropriate for restorative types of yoga, where movements are slower and poses are held for longer periods, potentially requiring extra layers of clothing or usage of blankets to stay warm.

Ultimately, the best ambient temperature for practicing yoga is one that feels most comfortable for your body. Listening to your own needs and adjusting the environment accordingly will help maximize the benefits of your yoga experience.
