I'm confused. On your 8h sleep video you said it was experimental and not really recommended because it was too long, and the ideal length would be around 90 min and then let the brain to their thing. Now you're saying that 3hs isn't recommended for being too short and 7hs to 9hs are the recommended. Can you clarify this a little? I'm very curious. I tried the power nap and it was incredible!
The "too short" and "too long" refers to the total sleep amount (whether using beats or not).
Even though I've provided many hours of sleep tracks (if people want to use them), I personally don't go longer than 90 minutes. But I'm weird like that. ;)
