Is drowsiness genetic?

While sleep disorders, as well as genetics research, there is some early evidence that suggests that drowsiness can be to some extent genetic. Research conducted in pairs of twins indicated a high level of correlation with regard to lack of sleep or feelings of fatigue and tired. Recent research has also found that a genetic variant that can be responsible for many people who cannot feel rest after sleeping, regardless of the time spent. There are also many environmental factors that can affect drowsiness and genetic factors usually deal with excessive tiredness despite the time spent sleep. Excessive drowsiness is often associated with the inability to feel fully rested and often fall asleep throughout the day, no matter how much time a person can spend by bedtime. As a understanding of human -religiousness, some connections and genetics were found during the end of the 20th and early 21st century.

One famous research study dealt with pairs of twins to see if there is a high correlation between each twins and feelings of drowsiness. The study found that it seemed that there was a trend in which there were feelings of fatigue or tired during the day more common in one twin if the other twin experienced such feelings. This suggests that there could be a genetic cause of these feelings and that someone can experience tired no matter how much sleep they receive because of genetic predisposition.

Newer research has found a genetic variant that can cause such drowsiness. In particular, one gene seems to indicate whether a person will be more likely to feel sleepy than someone else, regardless of the amount of the Sleep that this person has received. It is assumed that about 25% wide public may have this genetic variant, although these people do not necessarily experience such feelings of drowsiness, but have only potential. ResearchIt is that these individuals often sleep slightly and can often awaken throughout the sleep.

Excessive drowsiness is usually described as feelings of tired or tired that exist while up, no matter how much sleep one gets. If someone sleeps only four hours a day for three days in a row, then he is likely to feel sleepy because of these environmental causes. However, someone who feels sleepy after three or four days of nine hours of sleep every night may have a sleep disorder.
