The Mysterious Benefits of Deep Sleep There are psychological benefits of deep sleep: By rapidly reducing sleep need, this stage of sleep is an especially refreshing part of the sleep cycle, unless you are wakened out of it, in which case you will feel very sluggish and may experience sleep drunkenness, during which it is unsafe to drive.

- Scientists believe that peaks and valleys of melatonin over time are important for matching the body’s circadian rhythm to the external cycle of light and darkness. The basal forebrain, near the front and bottom of the brain, also promotes sleep and wakefulness, while part of the midbrain acts as an arousal system. Release of adenosine (a chemical by-product of cellular energy consumption) from cells in the basal forebrain and probably other regions supports your sleep drive.

What Is Light Sleep vs. Heavy Sleep, and How Can You Get What You Need? Light and Deep Sleep. During sleep, you alternate between cycles of REM (rapid eye movement) and NREM (non-rapid eye movement) that repeat about every 90 minutes. You spend about 75 percent of the night in NREM sleep, which consists of four stages of increasing relaxation. Stage one, or the phase between being awake and asleep, is considered light sleep. Deeper sleep begins in stage two, as your breathing and heart rate become regular and your body temperature drops.

- Deep sleep is when the body restores itself, and alcohol can interfere with this, explains Dr John Shneerson, head of the sleep centre at Papworth Hospital in Cambridge. As the alcohol starts to wear off, your body can come out of deep sleep and back into REM sleep, which is much easier to wake from. That's why you often wake up after just a few hours sleep when you've been drinking..

Why a Good Nightâs Sleep is GREAT for weight loss You burn more calories when you are in a deep sleep than when you are just lying reading in bed or tossing and turning. Nighttime calorie burn is dependent on REM or rapid eye movement sleep. When you are in REM sleep, your brain is highly active; sometime more active than when you are awake.

Feel-Good Brain Chemical's Role in Sleep The researchers therefore thought this protein may be important in the circadian rhythm — your body's daily cycle of proteins that regulate daily patterns of feeding, sleeping, body temperature and other functions. During the night, the pineal gland produces a hormone called melatonin that makes you sleepy.

Deep Oscillation Therapy DEEP OSCILLATION helps stimulate local immunity. During treatment inflammation mediators are released, and the body's own local defensive functions increased, therefore the therapy has a highly significant anti-inflammatory effect. It helps to speed up and improve the body’s natural wound-healing processes.

Sleep monitors explained: Rest longer and feel better Stages 3 and 4 – These are 'deep sleep'. It is very hard to wake up from deep sleep because this is when there is the lowest amount of activity in your body. It is also the part of sleep where your body rebuilds itself, restores energy and hormones are released.

- Sleep is important to a number of brain functions, including how nerve cells (neurons) communicate with each other. In fact, your brain and body stay remarkably active while you sleep. Recent findings suggest that sleep plays a housekeeping role that removes toxins in your brain that build up while you are awake.

Sweet Dreams: How Sugar Impacts Your Sleep But digging into those cookies or that bowl of ice cream means that you’re pumping lots of added sugar into your body—something that can negatively impact the quality of your sleep. In fact, the more sugar that you eat during the day, the more often you’re going to wake up in the middle of the night. Even if you don’t fully wake up, the sugar in your system can pull you out of a deep sleep, making you feel exhausted the next day. On top of that, consuming too much sugar during the day can lead to an energy crash. Eating lots of sugar reduces the activity of what are called orexin cells.

Exploring The Function Of Sleep Their hypothesis is that sleep allows the brain to regroup after a hard day of learning by giving the synapses, which increase in strength during the day, a chance to damp down to baseline levels. This is important because the brain uses up to 80 percent of its energy to sustain synaptic activity.

How Deep Relaxation Affects Brain Chemistry How Deep Relaxation Affects Brain Chemistry. Deep relaxation and meditation have long been known to help with anxiety disorders and major depression.

One of the vital roles of sleep is to help us solidify and consolidate memories. As we go about our day, our brains take in an incredible amount of information.
