When I can’t sleep, I turn around and sleep “upside down” - moving my pillows to where my feet were beforehand, and my feet to where my head was beforehand - and I stick with that for a week or so. It gives me a week or so without insomnia and then wears off, so I have to turn myself back around for the next 7-12 day period.
Admittedly this could just be a me thing, but let’s put our faith in this method and let the power of placebo effect take hold. Boom, minor bouts of sleeplessness are cured.
What are your own examples of this?
If you can’t find a comfortable temperature when you’re sleeping under blankets, just stick one foot, and maybe part of your lower leg, out from under of the blankets. It acts like a radiator, and will release much of your excess heat.
A kid showed this to me at a childhood slumber party, and it’s been a useful tip ever since.
