I've found that writing by hand helps to get me to sleep. However, I can't do that these days because I have to hold my nipple in my baby's mouth, so I've been singing to my baby instead.
Looking at the blue light from electronics can prevent your body from producing melatonin. Using a red or amber light in the bedroom can help, too. Personally, I use a lamp with three of these:
LED Flame Effect Light Bulb, 4 Modes Flame Lights Bulbs, E26 Base Fire Light Bulbs with Gravity Sensor, Christmas and Halloween Flickering Light Bulb for Indoor/Outdoor/Home/Party Decor (4 Pack) - - Amazon.com

I've also used red fairy lights in the past, but I don't currently have those set up:
JMEXSUSS Christmas String Lights Red, 91.5ft 250 LED Green Wire Waterproof Fairy String Lights with 8 Lighting Modes, LED Lights Christmas Decorations - - Amazon.com

STUDY! Such a simple solution.
Yes, I did this back when I was in university, but that's all behind me now! It is particularly helpful for memorization. I hate memorization, and I would up taking a viticulture and enology class that was supposed to be one of my fun classes but turned out to be mostly memorization. I'd look at my notes before bed and just repeat the information in my head until I went to sleep. I don't remember much of it today, though. That's the problem with memorization. It doesn't really last the same way that concepts do.
I've been trying to talk my husband into doing it, but he has a habit of playing games and coming to bed at 3am instead.
