Insomnia may be temporary and stem from a simple cause, such as jet lag. Sleepwalkers can perform a range of activities - some potentially dangerous, like leaving the house - while they continue to sleep.
Night terrors are often more frightening for parents than for their child. Sometimes children who have night terrors remember a frightening image, but often they remember nothing. A night terror can be dramatic: Your child may wake up screaming, but unable to explain the fear. Often, there is no clear cause.īoth night terrors and sleepwalking arise during NREM sleep and occur most often in children between the ages of 3 and 5 years old. They can be caused by stress, anxiety, and some drugs. Nightmares are frightening dreams that arise during REM sleep. Restless legs syndrome is a common problem among middle-aged and older adults. This can delay sleep onset and cause brief awakening during sleep. They feel an urge to move their legs and feet to get temporary relief, often with excessive, rhythmic, or cyclic leg movements during sleep. In people who have restless legs syndrome, discomfort in the legs and feet peaks during the evening and night. Instead, they experience constant sleepiness during the day. Though dramatic and uncontrolled "sleep attacks" have been the best-known feature of narcolepsy, in reality many patients do not have sleep attacks. There is sometimes a genetic component, but most patients have no family history of the problem. Narcolepsy is a brain disorder that causes excessive daytime sleepiness. After delivery, the new baby's care or the mother's postpartum depression may interrupt sleep. Later in pregnancy, vivid dreams and physical discomfort may prevent deep sleep.
During the first trimester, frequent trips to the bathroom and morning sickness may disrupt sleep. Women often experience sleepless nights and daytime fatigue in the first and third trimesters of their pregnancy. If left untreated, severe sleep apnea may be associated with high blood pressure and the risk of stroke and heart attack. 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 may also be a marker of a more serious sleep problem called sleep apnea.
Snoring can be a problem simply because of the noise it causes. The noise is produced when the air you inhale rattles over the relaxed tissues of the throat. Insomnia has many possible causes, including stress, anxiety, depression, poor sleep habits, circadian rhythm disorders (such as jet lag), and taking certain medications. Insomnia is a problem if it affects your daytime activities. They may have trouble falling asleep or may wake up frequently during the night or early in the morning. People who have insomnia don't feel as if they get enough sleep at night. Abnormalities related to this clock are called circadian rhythm disorders ("circa" means "about," and "dies" means "day").Ĭircadian 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). Light and exercise "reset" the clock and can move it forward or backward. It sits just above the nerves leaving the back of our eyes. This clock is a small part of the brain called the suprachiasmatic nucleus of the hypothalamus. 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." Sleepiness puts you at greater risk for car wrecks and other accidents. When you're repeatedly interrupted and can't cycle normally through these types and stages of sleep, you may feel tired, fatigued, and have trouble concentrating and paying attention while you're awake. Stage 1 of NREM sleep is the lightest, while stage 4 is the deepest.
