Why do we sleep? To clean our brains, say US scientists Scientists say they may have found the reason why we need to sleep. Photograph: Corbis Scientists in the US claim to have a new explanation for why we sleep: in the hours spent slumbering, a rubbish disposal service swings into action that cleans up waste in the brain. Through a series of experiments on mice, the researchers showed that during sleep, cerebral spinal fluid is pumped around the brain, and flushes out waste products like a biological dishwasher.

This Is Why We Sleep What It\'s Like to Go to Sleep at 9 Every Night Larger synapses remained unaltered in the mice, which led the researchers to believe they held more important memories. During sleep, we are much less preoccupied by the external world … and the brain can sample [or assess] all our synapses, and renormalize them in a smart way, study co-author Dr. Chiara Cirelli told Live Science. This shrinking-to-forget process may just be one function of sleep, and it may not be be the direct reason humans and animals do it.

The HuntleyâBrinkley Report Huntley-Brinkley Report. The Huntley-Brinkley Report (sometimes known as The Texaco Huntley-Brinkley Report for one of its early sponsors) was NBC's flagship evening news program from October 29, 1956 to July 31, 1970. It was anchored by Chet Huntley in New York City, and David Brinkley in Washington, D.C.

- Looking at the contribution of sleep disorders to unrefreshing sleep is the role of a sleep study in evaluating the symptom of unrefreshing sleep. Unrefreshing sleep, whilst common, usually has an underlying cause. By identifying and treating that cause, daytime function can be improved.

Sleep Study for a Child They can wear matching pajamas, order take-out food, and stay up as late as they like. This helps take the pressure off the child falling asleep since the sleep study is to find out what happens during sleep. The children typically sleep better than the parents do. I also tell children the same rules apply in the sleep clinic as in their home; if they're able to jump on the bed at home they can do it here.

Sleep, Learning, and Memory Research suggests that sleep helps learning and memory in two distinct ways. First, a sleep-deprived person cannot focus attention optimally and therefore cannot learn efficiently. Second, sleep itself has a role in the consolidation of memory, which is essential for learning new information.

- Sleep studies are tests that measure how well you sleep and how your body responds to sleep problems. These tests can help your doctor find out whether you have a sleep disorder and how severe it is. Sleep studies are important because untreated sleep disorders can raise your risk for heart disease, high blood pressure, stroke, and other medical conditions. Sleep disorders also have been linked to an increased risk of injury, such as falling (in the elderly) and car accidents.

Is sleep that important? During REM sleep our eyes twitch, our limbs and facial muscles may move and we dream. (You can read more specifics about sleep in our article How Sleep Works .). One sleep theory is that ou­r brain goes over the information it received that day and decides what should stick around and where it should go. Think of your brain as a computer desktop. During the night, anything we learned that day is filed away in the proper folders, or moved to the recycle bin. Behavioral research supports this notion, but sleep is so mysterious and different for each person that it's tough to get conclusive results.

Why do we sleep? We also know that during sleep, the brain orchestrates the manufacture of many different types of molecules — proteins, steroids, cholesterol, lipid rafts, human growth hormone, and many more.

Home Sleep Testing - Everything You Need To Know This is typically done in a sleep lab, requiring the patient to spend the night in-lab, while the polysomnography (PSG) equipment records his/her physiological data. However, today with technological advancements a polysomnograpy can be performed at home and is called home sleep testing (HST) or a home sleep study. The patient self-administers the home sleep test, and is able to spend the night in the patient’s own bed in familiar surroundings (reducing first night effect).

Understanding The Sleep Study Arousal  The stimulation of the brain, causing the subject to go from deep to a lighter level of sleep. This can be easily detected during a sleep study as a change in sleep stage. Arousal can be due to low blood oxygen, high blood carbon dioxide, jerky leg movements, or environmental factors such as loud noises.

- The gold standard used to scientifically evaluate a person's sleep is a thorough sleep lab test, called polysomnography. Compared with this test, the accelerometer-based fitness trackers are easy to trick, Montgomery-Downs said.

Sleep, Learning, and Memory Research has also focused on sleep and its role in procedural memory —the remembering how to do something (for example, riding a bicycle or playing the piano). REM sleep seems to plays a critical role in the consolidation of procedural memory.

Why Do We Sleep, Anyway? Yet, despite decades of research and many discoveries about other aspects of sleep, the question of why we sleep has been difficult to answer. The lack of a clear answer to this challenging question does not mean that this research has been a waste of time.

Sleep Medicine Sleep Medicine The University of Chicago is the longtime leader in the field of sleep disorders. The world’s very first sleep laboratory, in fact, was established at the University of Chicago, in the late 1920’s.

How Does a Sleep Study Work? Often these disorders cannot be identified with a normal office visit—your doctor needs to gather more conclusive evidence while you're asleep. A sleep study is a non-invasive, overnight exam that allows doctors to monitor you while you sleep to see what's happening in your brain and body. For this test, you will go to a sleep lab that is set up for overnight stays—usually in a hospital or sleep center.

Sleep, Learning, and Memory Another area that researchers study is the impact that a lack of adequate sleep has on learning and memory. When we are sleep deprived, our focus, attention, and vigilance drift, making it more difficult to receive information.

A BRIEF HISTORY OF SLEEP RESEARCH Modern Sleep Research. Today, sleep research comprises many different areas: narcolepsy research; sleep and cardio-respiratory research; and studies of pain and sleep, circadian rhythms, shift work and its effects on sleep, sleep deprivation, sleep and aging, and infant sleep, to name a few.

Sleep and Memory Sleep and Memory. During sleep, your brain is taking your memories, reactivating and looking at them again, and storing them in a more efficient and effective form.Dr. The Takeaway. Only 11 percent of American college students sleep well, and 40 percent of students feel well rested only two days per week. Inadequate sleep appears to affect the brain's ability to consolidate both factual information and procedural memories about how to do various physical tasks.

Sleep your way to more muscle As we sleep, energy consumption is lowered, allowing us to use the high-quality food we eat during the day to more efficiently build muscle. Growth hormone is naturally released, improving muscular recovery and regeneration. Also, as we sleep the brain recharges. This is important for building muscle because a rested brain is a motivated and focused brain. In simple terms, when you sleep, you recover, and when you recover you replace, repair, and rebuild—all of which are needed for optimal progress..

The Science of Circadian Rhythms and Their Impact on Sleep Circadian rhythms may be the most difficult concept to understand in the world of sleep medicine. There is a lot of confusing language, and it relies on science that is not easily approached. Fortunately, a basic understanding of the science of circadian rhythms can be obtained and may help to explain some cases of insomnia and daytime sleepiness. As the World Turns. The Earth’s 23 hour and 56 minute daily rotation provides predictable rhythms of light and temperature, food, and predator activity.

Preparing for a Sleep Study Sometimes you may need to stay after your sleep study to take a daytime nap study. This study is called a Multiple Sleep Latency Test (MSLT). It is used to see how quickly you fall asleep in quiet situations during the day. The MSLT is the standard tool used to evaluate people who are thought to have narcolepsy.

- What To Expect During a Sleep Study. Sleep studies are painless. The polysomnogram (PSG), multiple sleep latency test (MSLT), and maintenance of wakefulness test (MWT) usually are done at a sleep center. The room the sleep study is done in may look like a hotel room.
