Sleep Too Much?

As college students, we often complain that we have not gotten enough sleep on any given night. We drink copious amounts of caffeine in order to stay awake and finish that paper. Many times, we compensate for a lack of sleep at night by taking naps after (and sometimes during) our classes. This behavior might be recognized as "normal" by many teenagers and young people. However, many college-aged people suffer from sleep disorders. The most commonly recognized among these is insomnia, or the inability to obtain an adequate amount of sleep. But often overlooked and potentially harmful is hypersomnia. Although we rarely identify it as a negative condition, many of us actually get too much sleep.

Hypersomnia is defined as excessive daytime sleepiness and/or nighttime sleep. Humans sleep for an average of eight hours a night. Those with hypersomnia may find themselves sleeping for over ten hours at a time. (2) The most common symptoms are napping at inappropriate times, difficulty waking up, anxiety, irritability, restlessness and fatigue. Some more serious symptoms may include hallucination, loss of appetite, memory loss, or the inability to hear, see, taste, or smell things accurately. The disorder can have a profound effect on one's ability to cope in social situations. (1) There is a range of possible causes for the condition, but the primary cause is described as abnormalities that occur during sleep or abnormalities of specific sleep functions. (2)

Those with hypersomnia are generally diagnosed in one of four categories by a polysomnogram, which monitors a patient during one night of rest. (2)

Post-traumatic Hypersomnia is caused by trauma to the central nervous system, such as a head injury or a traumatic accident. This kind of hypersomnia may last for a span of a few days or an entire lifetime following such an incident.

Recurrent Hypersomnia consists of episodic periods of extended sleep followed by periods of normal sleep. The length of these episodes varies. Recurrent hypersomnia is caused by dysfunction of the hypothalamus.

Idiopathic Hypersomnia has no known cause and is the diagnosis most closely associated with the sleep disorder narcolepsy.

Normal Hypersomnia is seen in people who are commonly referred to as "long sleepers," those who require more than ten hours of sleep per night as a result of genetic predisposition. (2)

Hypersomnia shares some common symptoms with other sleep disorders: narcolepsy and sleep apnea. Narcolepsy consists of episodic "sleep attacks" during the daytime regardless of one's nighttime sleep. It resembles hypersomnia in the respect that many experience onset during teenage and young adult years. Sleep apnea is a condition which causes intermittent shortness of breath during sleep. It affects people of all ages but bears a resemblance to hypersomnia in that it is caused by an abnormality of respiratory function during sleep. Like normal hypersomnia, it also tends to...
