Five readings on sound and the body.

• 01 What relaxing actually is Deep rest is not a mood. It is a change of state, visible in the heartbeat, and sound is one of the shortest routes into it. Relaxing
• 02 Recovering, on purpose What twelve weeks of low frequency sound did for pain and disability in one small trial, and what sleep research does and does not support. Recovering
• 03 Releasing anxiety, and what the trials show Music therapy carries the strongest evidence in this field. Receptive listening outperformed playing, and duration mattered more than most people expect. Releasing anxiety
• 04 Resetting the nervous system Heart rate variability, vagal tone, and the cortisol claim we will not make. A close read of four studies, including one null result. Resetting
• 05 Stories of sound frequencies Forty hertz in a clinic. A quarter of a hertz in an afternoon nap. Sixteen to one hundred and sixty through the hands and feet. Four numbers, four studies. Frequencies

Every piece cites named studies with working links. Where a claim has no study behind it, we write it as experience, not as science. This is wellness content, not medical advice.
