Avoid caffeine:
It keeps you awake and that's now what you want for a good nights sleep. We all know that.
Read a fiction book:
It takes you to a whole new world if you really get into it. And then take some time to ponder over the book as you fall asleep. I find as I read more and more, regardless of the book, I get more tired at night and so find it easier to fall asleep. Different for others?
Have the room slightly cooler:
I prefer this to a hot room. I prefer to turn off the heat and allow the coolness to circulate in and out of the windows. If I get cold, I wear warmer clothes. It also saves on the bills as you are not going to require the heat all night long.
Sleep in silence:
I find sleeping with no music or TV on more easy and restful. I guess others are different, but sleep with no distractions is best for a clearer mind.
Avoid alcohol before bedtime:
It's a depressant; although it may make it easier to fall asleep, it causes you to wake up during the night. As alcohol is digested your body goes into withdrawal from the alcohol, causing nighttime awakenings and often nightmares for some people.
