What Is “Weightless”?
Released in 2011 by the British ambient band Marconi Union, “Weightless” is an 8-minute soundscape meticulously composed in collaboration with sound therapists from the British Academy of Sound Therapy and Radox Spa. It uses gentle synths, piano, slow harmonies, and natural audio to create a deeply calming listening experience.
Time magazine even labeled “Weightless” as **“the world’s most relaxing song.”**
What Makes It So Relaxing?

the world’s most relaxing song
A 2014 study by Mindlab International found that listening to “Weightless” reduced anxiety by up to 65%, slowed heart rate, and significantly lowered blood pressure by up to 35%—more effective than any other tested tune.
The song’s tempo starts at around 60 BPM—matching a typical resting heart rate—and gradually slows to about 50 BPM, a technique called entrainment, which helps synchronize the listener’s physiological state with the music’s pace.
When & Why to Listen
- To reduce anxiety before exams, presentations, or stressful moments.
- As a sleep aid, especially for those with insomnia or racing thoughts.
- For mindful breaks, deep focus, and stress reduction throughout your day.
