I recently stopped using a sleep mask and blackout curtains and went from needing 9 hours of sleep to needing 7.5 hours of sleep without a noticeable drop in productivity. Consider experimenting with stuff like this.
This is convincing me to buy a sleep mask and blackout curtains. One man’s modus ponens is another man’s modus tollens as they say.
Are you talking about measured sleep time or time in bed?

Less melatonin production during night makes it easy to get up?
I notice the same effect for blackout curtains. I required 8h15m of sleep with no blackout curtains, and require 9h of sleep with blackout curtains.
