Exploring the Myths and Realities of Hot Yoga and Toxin Release

Can knowing about the health benefits of hot yoga help individuals decide if it is right for them?

Hot Yoga

The body has a system for ridding itself of what it can’t use or doesn’t need, called toxins. Individuals may have heard that they can sweat out toxins by doing various hot yoga styles. Hot yoga, practiced in a heated room, has become popular. The standard room temperature is around 105 degrees Fahrenheit with 40% humidity. (Mayo Clinic 2020) Because of the temperatures, hot yoga is not for everyone, and those with heart problems or dizziness are recommended to stick with regular classes. However, the detoxification medical benefits may not be there, or there is still insufficient research to confirm.

Body Detoxification

Broken down by the liver, the toxins in the blood or bile are filtered in the kidneys or intestines and removed in urine or stool. (Boyer J. L. 2013) Sweat is not part of the removal equation. The function of sweat is to cool the body down when it becomes overheated. This can happen during strenuous activity, when overdressed, or in summer. Sweat comprises primarily water with trace amounts of urea, lactic acid, and minerals. (Baker L. B. 2019) Except for water, none of the products in sweat are excreted in large enough quantities to alter or improve metabolic function. The sodium excreted in sweat is quickly re-absorbed through the skin’s epithelial sodium channels, which does little to alter the sodium levels in the blood. (Hanukoglu I. et al., 2017)

Environmental Toxins

The body is exposed to all sorts of toxins daily, including pollution and pesticides in the air, preservatives in our foods, and detergents and cosmetics on our skin. (Hunt P. 2011) Sweat-based exercise to remove these toxins is still unfounded.

Sweating In Hot Yoga

Many think that sweating in a hot yoga class will cleanse the alcohol or unhealthy foods. Yoga won’t help sweat these things out, but the practice still provides benefits that help burn some fat from the calories consumed. Exercising helps burn fat regardless of the temperature of the surroundings. (Swift, D. L. et al., 2014) The benefits include:

• Increased circulation to deliver more oxygenated blood to the muscles.
• Improved muscle tone and flexibility.
• Stress relief.

Instead of sweating out the toxins, minimize exposure by eating a healthy, balanced diet, using natural products, and reading the labels of products placed on or in the body.
