I've long thought that always getting plenty of sleep is what allowed me to be as academically successful as I have been. Here's an excellent and brief article about what helped, and didn't help, one author get better sleep:
Over a week later, I’m happy to report my sleep schedule is back on track, and I’m logging 7 to 8 hours per night. I think it’s a combination of all of the strategies above, but I believe that following a relaxing bedtime routine and keeping my phone away from my bed delivered the most benefits. Plus, they’re totally doable and don’t require any big purchases. There have been a couple times when I woke up during the night, but overall, I feel way more rested today than I did one week ago—and I only had one cup of coffee.
Hey students: well rested, well tested.
