The idea that humming helps the vagus nerve and heart rate variability has spread online.
The claim appears in lifestyle stories and wellness guides across Asia (Times of India).

In Thailand’s vibrant health scene, from upscale Bangkok spas to local clinics in Chiang Mai, a short daily hum has gone viral as a quick fix for heart and brain function. New research in PLOS ONE suggests the reality is more nuanced. While five minutes of humming may not instantly sharpen minds, it reveals meaningful physiological effects that Thai families can consider within a broader wellness toolkit.

Leading with impact, researchers tested whether brief humming sessions could boost cognitive performance. Across hundreds of participants, results showed that isolated humming did not consistently improve short-term memory or quick thinking. In some cases, verbal recall and reaction times declined under controlled lab conditions. The takeaway: humming is not a magic cognitive boost.

Five minutes of daily humming, promoted through viral social media posts and lifestyle magazines, promises instant improvements to both heart and brain function. However, groundbreaking research published in PLOS ONE reveals a more nuanced reality that challenges these sweeping claims while uncovering genuinely intriguing physiological effects that deserve Thai families’ thoughtful consideration.
