This technique is adapted from author Jonathan Goldman. He says that simple, self-created vocal sounds such as elongated vowels like “ah”, “oh” or even an “mmm” humming sound can have profound and positive effects on your physical, mental and emotional states.
For example, Goldman says these sounds can:
1. Calm your nervous system, lower blood pressure and heart rate, and can reduce levels of stress-related hormones such as cortisol.
2. Increase melatonin, a hormone which helps us sleep at night.
3. Release endorphins—those self-created “feel good” brain chemicals.
Feeling stress or anxiety? Take a nice deep breath and sound forth with an “ah” a few times….or just hum for a minute or two. No one will hear you but you’ll feel a lot more relaxed almost instantly.
