Most people don't realize they oversleep when they have a condition called hypersomnia and that's due in part to recurring episodes of excessive daytime sleeping and prolonged nighttime sleep. This is different from the average person taking that midday nap when they do it at sometimes the most inappropriate times like at work, during meals, or even in conversation with people.

Hypersomniacs are also diagnosed with narcolepsy, which can be quite dangerous because some individuals are behind the wheel of cars or even cooking in their home and aren't aware that they fell asleep. Some hypersomniacs and narcoleptics can fall asleep and then wake up and resume where they left off in conversations with people. Usually daytime naps usually provide no relief or symptoms to the problem(s) and will result in the individual(s) having increased difficulty in waking from a long extended period of sleeping, disorientation, anxiety, decreased energy, increased fatigue, restlessness, slow thinking, slow speech, loss of appetite, hallucinations, and problems with memory functions.

Some individuals also experience losing the ability to function in normal family, social, occupational, and other settings familiar to that person.

Hypersomnia can be triggered by sleep apnea or narcolepsy, where it can lead to dysfunction of the autonomic nerve system, which can be brought on, by acute alcohol and/or drug abuse. In some cases rare or not it can also be triggered from physical problems such as tumors, head trauma or injuries to the nervous system. Specific medications or withdrawal of medications and/or drugs may contribute to someone having hypersomnia. Medical conditions such as multiple sclerosis, depression, encephalitis, epilepsy, and obesity can contribute to hypersomnia as well.

It's also been noted that those who have hypersomnia are also genetically dispositioned to this problem whereas in others there's no known or documented cause. Hypersomnia typically affects adolescents and young adults in their 20s and 30s. Although the most common causes of this disorder differs in the age brackets. Information can be located on the National Institute of Neurological Disorders and Strokes website if you're seeking a more thorough clinical explanation to this problem. This isn't a substitute for medical advice from a licensed physician so it's ideal to educate yourself, but leave the diagnosing and treatment to a doctor so that you condition can be monitored closely.

People who are not seeing a doctor when they identify problems that are not normal for them to experience are misdiagnosing too many issues with sleep. Persons who are severely obese can also have a difficult time losing the weight because of the fact that lack of sleep can increase the body's metabolic rate, which can trigger excessive hunger in those who are trying to lose weight.

This is why so many people who are obese are eating more than they should because a lot of them sleep so much that they wake up wanting to eat when they should be sleeping like normal people do and not up at all hours of the night wanting to eat. This is why it's harder for people who are obese to lose weight when they sleep too much and not training their body to rest instead of wanting to eat food.
