Insomnia is a sleeping disorder that is characterized by problems with falling asleep, maintaining sleep and early waking. This sleep problem must have occurred for at least 3 nights per week and cause major distress to the person. It must also affect the person’s day time functioning.
The prevalence of insomnia is quite high in Nigeria. In one research family clinic at Ile Ife, about 49% had insomnia. In one study, between 52% and 73% of the adult population had insomnia over one year period. And in some communities in the southwest, 26% of the elderly had insomnia.
Even though sleeping tablets are not available over the counter in Nigeria, somehow, some still get it. Sometimes they visit doctors who give them medication prescriptions for these sleeping tablets. The unfortunate aspect is that most people do not know that taking these medications for long, can cause them harm. And death can also ensure.
There are safe ways to treat insomnia. In medicine it is better to treat cause, than to treat symptoms.
Stages and cycles of sleep.
The act of sleeping is not as straight as it looks. Sleep occurs in stages. Each stage has its own important functions.

Dosing off stage. It is light sleep and it is easy to wake up the person at this stage of sleep. The breathing, heart rate, and the eye movements slow down. The muscles in the body begin to relax. The brain activities also begin to slow down.
The eye movements stop altogether at this stage. All the organs slow down and body temperature begins to drop.
This stage of NREM sleep is called delta sleep. It is deep sleep. Breathing and heart rate reach to their lowest levels. And because the muscles are so much relaxed at this stage, it is difficult to wake the person. This stage of sleep is very important because it is a restorative sleep. It helps the body repair itself. It also helps in thinking and creativity, as well as in memory.
The Rapid Eye Movement (REM):
Here, the eyeballs move very fast from one side to another. And brain activities speed up.
The activities of other organs also increase, like breathing and heart rate. The blood pressure also increases.
