Sleep deprivation studies have found that just about all people at one time or another will suffer from insomnia. For some of them this condition will only last a day or two, while for others it can last for months or even years. This type of sleeping disorder causes a lack of sleep, restless sleep, irritability psychological issues and trouble concentrating.

Insomnia symptoms include having trouble falling asleep or staying asleep, and waking up in the middle of the night. These folks then feel tired during the day, and having trouble concentrating on the tasks at hand.

There have been a number of sleep deprivation studies performed over the years. A study performed in 1976 looked at those who were sleep deprived over a period of five nights, and found that a lack of sleep really started to take its toll after night number three. This is when people started to get confused, they became irritable, and their attention span was seriously shortened. By the fourth night, people reported their head was too small for their body, and by the fifth night, people suffered mental disturbances, a condition known as sleep deprivation psychosis.

Sleep deprivation studies have also been carried out on animals, including rats and other animals that are very small. It was discovered that animals suffer more severe effects of sleep loss than human beings do. Animals were more inclined to bite people and/or attack other creatures.
