When looking for Sleep Help An all important Sleep Help tip is to select a time of night when you disconnect from work. Few things stimulate the mind like work can. In our amazing age of technology it is increasingly difficult to fully unplug from work. However, this is vital to your health and greatly affects the quality of your sleep. It goes without saying that caffeinated foods and beverages should be shunned before it is time to go to sleep. However, few people realize that caffeine takes approximately six to eight hours to completely get out of your system. That being said, if you are experiencing trouble falling asleep you should do much more than decline an after dinner cup of coffee.
