Techniques
For me there are a few simple techniques that I use and I'll talk a little about each one below:
Darkness
For me, there's one thing I can't do without when it comes to sleep and that's darkness. I'm a bit of an owl in that I like total coal-black darkness in order to fall asleep. This means no hall lights, blinds / curtains cut and closing doors to rooms which permit light from outside in.
Quiet
I like real quiet when I go to bed, the dead space is like a blanket and wraps around your mind and body, sending me to sleep. To remedy any noises from outside, I don't go to sleep early and if there is an occasional ambient noise, I focus on the silence and apply a pillow to my ears.
Airflow
It has been proved through countless sleep studies that a good flow of cold (not freezing) air through your bedroom can help put your body to sleep and help you relax. I always have my window open a crack. This cold air is hard to come by in summer so I just switch out a duvet for simple sheets and this helps attain the desired coolness.
Sheets
As mentioned above, I use a bed covering appropriate to the season. In the height of summer, I use a couple of thin comfy cotton sheets to drape over myself to keep the chill off. In the winter, I snuggle under a thick duvet of many tog.
I hope these tips help you get some good rest yourself
