Common sleeping disorders often begin unnoticed. We might just be having signs of some minor problems but we don’t think too much of it. Then we may begin to have difficulty falling or staying asleep but think this is only a “passing phase”. Little do we know, we are already experiencing, what doctors would diagnose as insomnia, a sleep disorder that results to sleepiness at other times of the day. Insomnia is the most well-known sleep disorder but it is still undiagnosed in thousands of people. It causes slow reactions in our nervous system and poor mental concentration. These factors might just lead to accidents and lesser productivity throughout the day. Stress is also considered one of the major reasons why one out of three adults experiences some degree of insomnia at one time or another.
