Convincing people that sleep is a problem worth caring about is half the battle.
There are many resources available that get into the practical/tactical aspect of improving sleep. But if you don't believe sleep is a problem yet, you won't seek those out.
The Huberman Lab has put out a number of good resources for this [0] including a podcast episode speaking with Matt Walker, PhD, sleep researcher and author of Why we Sleep [1] (also a good read).
I've been a night owl for most of my life, and only more recently did I fully realize how connected this behavior was to traumatic situations growing up. When I started going down the rabbit hole on how to improve sleep, it was encouraging to find the emergence of a ton of practical non-pharmaceutical resources (I did try sleep aids for awhile, but couldn't deal with the side effects).
The hard part is that it does require willingness to implement real changes. They're not pleasant at first, but I went from an average 3AM-10AM sleep cycle to 10PM-6AM, and I've realized that all the things I told myself over the years about needing to be up all night were simply untrue.
I started this journey by setting a goal for myself to see/photograph a sunrise. I now regularly take pre-dawn walks and have seen more sunrises in the past few weeks than I had during the prior 30+ years of my life.
It's worth the effort.
