Natural Patterns of Sleep
According to the National Sleep Foundation , research shows that most adults need 7 to 9 hours of sleep each night. But other findings suggest that the type of sleep we get is more important than the duration of our sleep. When we sleep, our body goes through five specific stages as noted by he National Institute of Neurological Disorders and Stroke. Each stage cumulates to REM rapid eye movement sleep, and then restarts, completing one cycle.
The first stage through REM takes about 90 minutes to complete, and adults typically need to complete at least four or five sleep cycles per night, or 6 to 9 total hours of sleep. Stage 1. Stage 1 of the sleep cycle is considered light sleep. When in stage 1, sleepers drift in and out of sleep, easily awakened. Physically, sleepers eyes and muscle activity slows down, but may experience muscle contractions.
Hypnic myoclonia is the proper term for this, and is often described as a falling sensation sleepers get when sleeping. When awakened during stage 1 sleep, most people are unable to remember simple things. Stage 2. In stage 2, your body drifts deeper into sleep as your eyes stop moving and your brain activity slows.
However, your brain will still have occasional bursts of sleep spindles, or small bursts of rapid brain waves. Stage 3. Your brain starts producing delta waves almost exclusively, and muscle and eye activity crawl to a stop. For children and some adults, stage 4 is where most sleepwalking, bedwetting, and night terrors occur. REM Sleep. Stage 4, or REM sleep, notices another physical change to the sleeper. Their breathing becomes faster, shallow, and irregular, followed by their eyes moving rapidly in various directions.
Your body slips into a short-term paralysis and your heart rate and blood pressure rises. For males, this often results in penile erections.
REM sleep is where dreams occur. Sleepers who awake during REM sleep usually have a better recollection of their dreams than if awakened during another stage.
Most sleepers will experience REM sleep about 70 to 90 minutes after they fall asleep. REM sleep also lengthens during sleep. As sleep cycles progress, the first few cycles spend longer in stage 3, whereas the last few sleep cycles see a bigger increase in stages 1, 2, and REM sleep. What It Means.

Brain Basics: Understanding Sleep

Until the s, most people thought of sleep as a passive, dormant part of our daily lives. Fast forward 70 years and we now know that our brains are very active during sleep. Moreover, sleep affects our daily functioning and our physical and mental health in many ways that we are just beginning to understand. Nerve-signaling chemicals called neurotransmitters control whether we are asleep or awake by acting on different groups of nerve cells, or neurons, in the brain. Neurons in the brainstem, which connects the brain with the spinal cord, produce neurotransmitters such as serotonin and norepinephrine that keep some parts of the brain active while we are awake. Other neurons at the base of the brain begin signaling when we fall asleep. Research also suggests that a chemical called adenosine builds up in our blood while we are awake and causes drowsiness.
Deep vs. Light Sleep: How Much Do You Really Need?
Slow wave sleep, also called deep sleep, is an important stage in the sleep cycle that enables proper brain function and memory. While most adults are aware that they should aim for between 7 and 9 hours of sleep each night, the science of sleep is quite complex. The two main categories of sleep are called rapid eye movement REM sleep and non-REM sleep, and each has important stages. There may be some ways to get both better sleep and more deep sleep each night, allowing a person to wake up feeling more rested and refreshed. The first stage of the sleep cycle is a transition period during which the body and brain shift from a state of wakefulness to one of sleep.

Most of us require between 90 to minutes of REM sleep each night, but it can be an elusive sleep stage to reach sometimes. Why is that? Having a few alcoholic beverages in the evening may be contributing to your lack of REM. Nicotine is another known culprit for suppressing this stage of rest according to a study. Not getting regular physical activity could be another reason for interrupted REM sleep, as one study found that the REM cycle was positively affected among subjects who worked out on a consistent basis.
What to know about deep sleep
According to the National Sleep Foundation , research shows that most adults need 7 to 9 hours of sleep each night. But other findings suggest that the type of sleep we get is more important than the duration of our sleep. When we sleep, our body goes through five specific stages as noted by he National Institute of Neurological Disorders and Stroke.

The first stage through REM takes about 90 minutes to complete, and adults typically need to complete at least four or five sleep cycles per night, or 6 to 9 total hours of sleep.
Our bodies require sleep in order to maintain proper function and health. In fact, we are programmed to sleep each night as a means of restoring our bodies and minds. Two interacting systems—the internal biological clock and the sleep-wake homeostat—largely determine the timing of our transitions from wakefulness to sleep and vice versa. These two factors also explain why, under normal conditions, we typically stay awake during the day and sleep at night.
Health and Wellness
How much sleep do we need and why is sleep important? Most doctors would tell us that the amount of sleep one needs varies from person to person. We should feel refreshed and alert upon awakening and not need a day time nap to get us through the day. Sleep needs change from birth to old age.
Your brain is very active during REM sleep and it is when the most vivid dreams occur. As a precautionary measure, your brain also sends signals to immobilize your arms and legs in order to prevent you from acting out your dreams. REM sleep and deep sleep also referred to as slow wave sleep are very different stages of sleep. It precedes REM sleep in a normal sleep cycle, and unlike REM your heart and respiratory rate decrease during deep sleep.
Now more than ever, we can quantify exactly how good or bad our sleep patterns are. Each morning you can review your heart rate, breath rate and sleep graphs with information about how much light, deep and REM sleep you had the night before. But all that data only makes sense if you know what you're aiming for and what it all means. Here's how to decode your sleep cycles so you can make the most of your shut-eye.
The average person spends around a third of their life asleep. In this time, our bodies are able to replenish energy stores and make repairs, while our minds organise and store the memories of the day before. The amount of sleep you need depends on your age, sex, health and other elements, and sleep cycles change as we grow older. This is divided into three stages, with each becoming progressively deeper. NREM3 becomes deeper, and if woken up, we can feel disorientated. Following on from this is rapid eye movement sleep REM , the stage at which we dream.
