Elevating legs against a wall for 10-15 minutes before sleep while relaxing or meditating may be beneficial for sleep.

“Before I go to sleep, I will lay on my back with my feet up. Oh, it feels good in the middle of the day. Like that for 10 minutes. There are actually studies done showing that this sort of blood recirculation, lymphatic drainage be very relaxing. [...] I will lay with my feet up on the wall for 10 minutes before I go to sleep. And I will just do deep breathing. I'll do box breathing. Four in, hold for four, exhale for four, wait for four. Or I will do four 78 breathing, inhale for four, hold for seven, exhale for eight. I'll do deep breathing. I'll just relax. I'm sort of trying to meditate while my feet are up on the wall. It helps me relax and I'm allowing the blood and the lymph to kind of drain back.”
