Getting enough sleep is one of the most important things you can do for your health—not to mention your productivity and creativity. Not only does your brain need quality sleep in order to “clean” and balance itself, but it’s also during slumber that the heart and blood vessels repair, the immune system strengthens and hormones are balanced.

What Are Sleep Disorders?

Circadian Rhythm Disorders

Typically, people sleep at night -- thanks not only to the conventions of the 9-to-5 workday, but also to the close interaction between our natural sleep and alertness rhythms, which are driven by an internal "clock."

This clock is a small part of the brain called the suprachiasmatic nucleus of the hypothalamus. It sits just above the nerves leaving the back of our eyes. Light and exercise "reset" the clock and can move it forward or backward. Abnormalities related to this clock are called circadian rhythm disorders ("circa" means "about," and "dies" means "day").

Circadian rhythm disorders include jet lag, adjustments to shift work, delayed sleep phase syndrome (you fall asleep and wake up too late), and advanced sleep phase syndrome (you fall asleep and wake up too early).


People who have insomnia don't feel as if they get enough sleep at night. They may have trouble falling asleep or may wake up frequently during the night or early in the morning. Insomnia is a problem if it affects your daytime activities. Insomnia has many possible causes, including stressanxietydepression, poor sleep habits, circadian rhythm disorders (such as jet lag), and taking certain medications.


Many adults snore. The noise is produced when the air you inhale rattles over the relaxed tissues of the throat. Snoring can be a problem simply because of the noise it causes. It may also be a marker of a more serious sleep problem called sleep apnea.

Sleep Apnea

Sleep apnea occurs when the upper airway becomes completely or partially blocked, interrupting regular breathing for short periods of time which then wakes you up. It can cause severe daytime sleepiness. If left untreated, severe sleep apnea may be associated with high blood pressure and the risk of stroke and heart attack.

Pregnancy and Sleep

Women often experience sleepless nights and daytime fatigue in the first and third trimesters of their pregnancy. During the first trimester, frequent trips to the bathroom and morning sickness may disrupt sleep. Later in pregnancy, vivid dreams and physical discomfort may prevent deep sleep. After delivery, the new baby's care or the mother's postpartum depression may interrupt sleep. 

Types of prescription sleeping pills

Prescription sleeping pills may help you fall asleep easier or stay asleep longer — or both. The risks and benefits of various prescription sleeping pills can differ. There are many prescription sleeping pills that causes dependence. It also could cause side effects as listed below.

Side effects of prescription sleeping pills

Always ask your doctor about potential side effects before deciding which sleeping pills to consider taking. Depending on the type, prescription sleeping pills may include side effects such as:

  • Dizziness or lightheadedness, which may lead to falls

  • Headache

  • Gastrointestinal problems, such as diarrhea and nausea

  • Prolonged drowsiness, more so with drugs that help you stay asleep
