This is great advice if your chronotype (innate circadian rhythm for your wake-sleep cycles) is that of the ‘early riser’/lion.

If you are a ‘9–5er’/bear, ‘night owl’/wolf, or ‘insomniac’/dolphin… it’s a bad idea. Sleep kryptonite!

As vulnerable pack animals that did most things by day, but needed to sleep safely at night, humans evolved a range of sleep patterns that made sure some portion of the tribe/band was always awake.

Check out “The Power Of When” (Dr. M Breus) to see what type you are and how to optimize your patterns and routines to fit your type.

It’s changed my sleep/life :-)
