According to the National Center for Complementary and Integrative Health (NCCIH) – a part of the National Institutes of Health (NIH) – around 21 million adults in the United States practice yoga, making it one of the most commonly used complementary health practices in the country.
The popularity of yoga is perhaps unsurprising, given the wealth of health benefits the practice has been associated with. These include reduced stress, anxiety, depression, and blood pressure, as well as improvements in back pain and overall physical fitness.
While previous research has suggested that yoga may also benefit people with asthma, the researchers of this latest review note that other studies have found limited or no benefits.
“Such information may confuse people with asthma when they are deciding whether or not to devote time and resources to the practice of yoga,” say the researchers, including lead author Dr. Zuyao Yang, of the Jockey Club School of Public Health and Primary Care at the Chinese University of Hong Kong.
