It is about the number of complete sleep cycles you go through over the night. Sleep cycles are repeated four to five times over the course of the night. Therefore, if you happen to finish four cycles after about six hours you may feel more relaxed than waking up after 8 hours but in the middle of a REM cycle.

The sleep cycle: A sleep cycle lasts about 90 minutes, and during that time we move through five stages of sleep. The first four stages make up our non-rapid eye movement (NREM) sleep, and the fifth stage is when rapid eye movement (REM) sleep occurs.

The first sleep cycle is often the shortest, ranging from 70-100 minutes, while later cycles tend to fall between 90 and 120 minutes. In addition, the composition of each cycle — how much time is spent in each sleep stage — changes as the night goes along.

Understanding Sleep Cycles Cycle 1: During light sleep you’ll dip into stage one and transition into stage two. Then you’ll move quickly into deep sleep, where you’ll stay for a while before going into 10 minutes or so of REM.

RBD can be treated with medication. However, it often occurs with other sleep problems or conditions, which may require additional treatment. If diagnosed, you should be monitored by your doctor. REM sleep behavior disorder may indicate a neurodegenerative disease or may be induced by some medications.

Diagnosis of RBD involves a clinical interview in which history of dream enactment behaviors is elicited and a subsequent overnight polysomnography (PSG) evaluation to assess for REM sleep without atonia (RWA) and/or observe motor behaviors during REM sleep.

Acute onset RBD is almost always induced or exacerbated by medications (especially Tri-Cyclic Antidepressants, Selective Serotonin Reuptake Inhibitors, Mono-Amine Oxidase Inhibitors, Serotonin Norepinephrine Reuptake Inhibitors,26 Mirtazapine, Selegiline, and Biperiden) or during withdrawal of alcohol, barbiturates.

Examples of treatment options for REM sleep behavior disorder include: Melatonin. Your doctor may prescribe a dietary supplement called melatonin, which may help reduce or eliminate your symptoms. Melatonin may be as effective as clonazepam and is usually well-tolerated with few side effects.

A typical starting dose of melatonin for RBD is 3 mg at bedtime, increased in 3 mg increments until behaviors subside (table 2). Most patients find relief with doses between 6 and 18 mg.

Why RBD occurs Sleepwalking is almost never involved in RBD. And after waking, the person may remember their dreams. RBD can precede the symptoms of Parkinson’s disease by many years.

Most people cannot detect the scent of Parkinson’s, but some who have a heightened sense of smell report a distinctive, musky odour on patients.

Sleep terrors are episodes of screaming, intense fear and flailing while still asleep. Also known as night terrors, sleep terrors often are paired with sleepwalking. Like sleepwalking, sleep terrors are considered a parasomnia — an undesired occurrence during sleep.

There are many reasons for tossing and turning at night, including poor sleep hygiene, an unbalanced diet, and even underlying medical conditions. Practicing good sleep hygiene, such as turning off electronics and keeping a consistent sleep schedule, can help you stop tossing and turning so much at night.

In summary Hypnic jerks and twitches are completely normal and quite common. They usually don’t indicate an underlying health issue and are simply a muscle contraction during sleep that ranges from mild to intense.

How to Stop Tossing and Turning All Night Long

1. Don’t stay in bed tossing and turning.
2. As soon as you’re sleepy, get back in bed.
3. When you get out of bed during the night, do a mind dump.
4. Avoid poor sleep behaviors.
5. Go to sleep when you’re sleepy and keep a regular wakeup time.
6. Get exposure to sunlight during the day, if you can.
7. Avoid bright lights near bedtime.

The average person moves about 13 times an hour during sleep. But some people barely budge, and others may move more than 100 times per hour.

Sleep-related groaning, also called catathrenia, causes you to groan vocally while you sleep. Sleep-related groaning is a long-lasting disorder that often occurs nightly. The groaning sound is usually quite loud. Your breathing becomes unusually slow during a groaning episode.

Sleep paralysis is a feeling of being conscious but unable to move. It occurs when a person passes between stages of wakefulness and sleep. During these transitions, you may be unable to move or speak for a few seconds up to a few minutes. Some people may also feel pressure or a sense of choking.

Articles On Dreaming When you get your ZZZs, you cycle between REM and non-REM sleep. REM stands for rapid eye movement. During REM sleep, your eyes move around rapidly in a range of directions, but don’t send any visual information to your brain. That doesn’t happen during non-REM sleep.
