Complementary and Alternative Medicine Therapies in relation to Self-Reported Better Sleep across Racial and Ethnic Groups in the United States
Using data from the 2012 National Health Interview Survey, this study found that while several Complementary and Alternative Medicine therapies like massage and yoga are associated with perceived better sleep across racial and ethnic groups, the effectiveness of other therapies such as chiropractic manipulation and herbal supplements varies significantly by race and ethnicity.

Sleep is a fundamental pillar of health, yet for millions of people, it remains elusive. Poor sleep is not just a matter of feeling tired; it is linked to serious physical and mental health challenges, including heart disease, diabetes, and depression. While doctors often prescribe medication or behavioral therapy to help people rest, these solutions are not always accessible or affordable for everyone. Consequently, many people turn to Complementary and Alternative Medicine, or CAM. These are health practices that exist outside of conventional Western medicine, ranging from herbal supplements and massage to meditation and yoga. Because these practices are often rooted in specific cultural traditions, researchers have long wondered if they work differently for people from different racial and ethnic backgrounds. Do a meditation practice that helps one group sleep soundly work just as well for another? Or do cultural differences change how effective these remedies feel?
To answer these questions, a team of researchers analyzed data from a massive, nationally representative survey of American adults conducted in 2012. They focused on nearly 9,300 people who had used at least one alternative therapy in the past year. The researchers asked a simple but crucial question: did the therapy that the participant considered most important to their health also help them sleep better? By looking at the answers across different racial and ethnic groups—including Non-Hispanic White, Black, Asian, Hispanic, and American Indian/Alaska Native adults—the team could see if the benefits of these therapies were universal or if they varied depending on who was using them.
The study revealed a clear pattern for several popular therapies. Practices that focus on the mind and body, such as massage, meditation, and movement techniques like yoga, Tai Chi, and Qigong, were consistently linked to better sleep across all racial and ethnic groups. Whether a participant was White, Black, Asian, or Hispanic, those who prioritized these therapies reported a higher likelihood of sleeping better. This suggests that the mechanisms behind these practices—perhaps reducing stress, relaxing muscles, or calming the mind—work similarly for people from diverse backgrounds.
However, the story changed when the researchers looked at other types of therapies. For chiropractic or osteopathic manipulation, which involves physical adjustments to the spine and joints, the results depended entirely on race. Among Non-Hispanic White adults, prioritizing this therapy was associated with a higher chance of reporting better sleep. In contrast, among Asian adults, prioritizing the same therapy was linked to a lower chance of reporting better sleep. For other groups, such as Black and Hispanic adults, the therapy showed no clear link to sleep improvement. Similarly, the use of herbal supplements told a different story. While herbal supplements were the most commonly used therapy overall, prioritizing them was associated with a lower likelihood of reporting better sleep. This negative association was strongest among Non-Hispanic White adults, who were significantly less likely to report sleep improvements from herbs compared to other groups.
The researchers also examined the use of traditional healers, a practice notably more common among American Indian/Alaska Native participants. While this group reported the highest overall rate of feeling that their most important therapy helped them sleep, the study could not definitively link traditional healers to better sleep outcomes due to the small number of participants in this category. The data was too limited to draw firm conclusions for this specific group, highlighting the need for more research that includes diverse populations in sufficient numbers.
Ultimately, the findings suggest that while some holistic approaches to sleep are broadly effective, others are not. The idea that alternative medicine works the same way for everyone is not supported by the data. Instead, the effectiveness of a therapy appears to depend on both the type of practice and the cultural context of the person using it. For mind-body practices, the path to better sleep seems to be a shared human experience. For physical manipulations and herbal remedies, the experience is far more complex and varies significantly across racial and ethnic lines. This does not mean these therapies are ineffective, but rather that their role in sleep health is nuanced. It underscores the importance of considering a person's cultural background and specific health beliefs when discussing sleep solutions, ensuring that the path to rest is tailored to the individual rather than assuming a one-size-fits-all approach.
