Alpha Waves and Sleep Music

"Alpha waves make you sleepy" gets it backwards.
The music still works, though.

Alpha Waves Are Not Sleep Waves

Alpha waves show up when you are relaxed with your eyes closed.

Once you actually fall asleep, they fade, and slower waves take over.

So alpha waves mark the calm state just before sleep. They are not the brain waves of sleep itself.

About "Alpha Wave Music"

Alpha waves are a result of being calm, not a cause of it.

Which means "this track generates alpha waves, so it will make you sleepy" has the causation the wrong way round.

It is also worth knowing that "alpha wave music" is not a regulated term. Anyone can put it on a thumbnail.

But Music Does Work

The label may be meaningless, but listening to music before bed has real evidence behind it.

Reviews that pool many studies find that people who listen to music at bedtime report sleeping better.

What is doing the work is not the alpha waves. It is simply that music calms you down.

So ignore the label and pick something you actually like.

What Kind of Music?

  • A slow tempo
  • No vocals
  • Little variation in volume or intensity
  • Classical, ambient, nature sounds

Lyrics give your brain something to follow. Best avoided at bedtime.

Thirty to forty-five minutes is about right, at a low volume.

Things to Watch Out For

Do not leave it playing all night. Once you are asleep it becomes a stimulus rather than a comfort, so set a timer.

Sleeping with earphones in is not great for your ears either.

In the end it comes down to taste. A track that is supposed to work will not calm you down if you do not enjoy it.
