As we age, our body goes through several changes and so does our sleep. Unfortunately as the body gets older it becomes more and more difficult to obtain a good night's sleep.
Sleep becomes more troublesome as people get older.
First of all, it often takes longer to fall asleep and once slumber finally is achieved, there are more awakenings throughout the night. On average, older individuals tend to get a little less sleep than their younger counterparts. Not only that, but the quality of an elderly person's sleep is different too. One major difference is that there is less deep sleep as one ages. More awakenings and lighter sleep lead to daytime sleepiness.
