Lots of great reccomendations here, highly reccomend looking into a sleep study or rework schedule like other folks are reccomending. Aside from that keeping a regimented schedule is always helpful, especially with reducing screen and bright light use near periods of rest.

Besides physiological stuff, reducing stress helps, learning what helps you personally sleep and wake up better and integrating that into you habits can help tons. I’ve found being able to even spend a short few minutes to properly reflect on the day can help change my mindset makes a difference.
