I've used various apps with Apple Watch for sleep analysis.

Not familiar with Whoop. I'll check it out

I also love 8 hours of sleep and aim for it.

Your philosophy makes sense.

I'd say you have conceded to over-hype and poor science.

I'm convinced the major parameter for most individuals to monitor regarding sleep is how they feel the next day.

Clearly, there are individuals with very severe sleep apnea who benefit from CPAP.

But there are no studies showing increasing your sleep time from 4 to 8 hours improves your life or health span or reduces your chances of heart disease
