Insomnia or chronic sleeplessness is considered a serious problem and can cause health problems due to lack of sleep. But too much sleep can be harmful as well. There are many people who need more than the average 7 to 8 hours of sleep daily and can feel sleepy even during the day time. Such need for excessive sleepiness disturbs both professional as well as personal life. In a nutshell, excessive sleeping tendency is also considered a major health condition that needs to be treated. In medical term this condition is called as hypersomnia or hypersomnolence.
Medically, hypersomnolence is expressed as a condition that involves feeling of excessive daytime sleepiness or EDS. This is also called by many as excessive daytime somnolence. It’s quite possible to confuse feeling of sleepiness with this condition. But the two feelings are quite different. Feeling sleepy due to less sleep in the night or tiredness or vigorous work is a different thing and hypersomnolence is a totally different condition. This condition is marked by chronic sleepiness and the person affected by this condition falls asleep anytime in the day irrespective of the place or work he is doing. Even though the patient gets naps in small breaks, he still feels sleepy more often and it becomes difficult for him to stay awake for longer time. Mostly after waking up the patients of hypersomnolence tend to feel confused and disoriented. Such condition makes a negative impact on the emotional as well as physiological balance of an individual.
Hypersomnia or hypersomnolence can be divided broadly in two types:
These two types are almost similar but differ in the instances of breaks in the sleeping pattern. The number of times the patient goes off to sleep defines whether he is suffering from idiopathic or recurrent hypersomnia. In both these conditions the motor reflexes of the patient are very sluggish and slow and mentally too they are almost all the time half asleep and less alert. Due to this they are absentminded and unstable and feel washed out very quickly.
The symptoms of hypersomnolence include:
Although hypersomnolence and insomnia are conditions both related to sleeping conditions they are not directly related. People suffering from insomnia have also been found to be suffering from hypersomnolence but vice versa condition is not possible. But in both the cases there can be some similarity in their symptoms. In both insomnia and hypersomnolence, a patient is disturbed both mentally as well as physically that can lead to emotional problems and stress. Memory impairment is also another common symptom in both these sleeping conditions.
