What is sleep
Sleep is an important part of your daily routine. You spend about a third of your time sleeping . Quality sleep and adequate availability at the right time, are essential for survival such as food and water. Without sleep , you cannot create or direct pathways in your brain that allow you to learn and create new memories and help to concentrate and respond quickly. Nerve cells
(Neurons) Sleep is important for a number of brain functions, including communicating with one another. In fact, your brain and body are noticeably active while you sleep. Recent research has found that sleep plays a role as a housekeeper in your brain that removes toxins from your brain so that you feel healthy while awake.
Everyone needs sleep , but its biological purpose remains a mystery. Sleep affects almost every type of tissue and system in the body. From the brain, heart and lungs to the role of sleep in metabolism, immunity, mood and immune system. Studies show that chronic sleepiness, or poor sleep quality, increases the risk of many other disorders, including cardiovascular disease, diabetes, depression, and obesity. Sleep is a complex and dynamic process in which scientists are now beginning to understand that sleep affects your day-to-day work. By reading this article you will find out the essentials of sleep and what happens to the brain during sleep .
The internal structure of sleep
Several structures in the brain are involved with sleep . Inside the brain called the hypothalamus , there is a group of peanut-shaped nerve cells that affect sleep and stress and act as a control center. The hypothalamus includes the suprachiasmatic nucleus (SCN) - a cluster of thousands of cells that receives information about the intensity of light directly from the eye and controls your behavioral rhythm.
Some SCN sufferers sleep involuntarily all day long because they cannot match their circadian rhythms with a light-dark cycle. Most blind people have some ability to understand the light and their sleep is able to correct that awakening cycle. The brain stem, which is located at the base of the brain, interacts with the hypothalamus to control the condition between our waking and sleeping. (This includes structures called the pons, medulla, and midbrain on the brain stem .) The cells that sleep inside the hypothalamus and brain stem produce a chemical called GABA, which stimulates the activity of the hypothalamus and brain stem.
The brain stem (especially the pons and medulla) sleep REMIt also plays a special role; It sends signals to the brain to relax the muscles needed for body posture and limbs, so that we do not make our dreams unfulfilled. The thalamus acts as a relay of information about sensory to cerebral cortex (brain covering that interprets and processes information from short to long-term memory). During most stages of sleep, the thalamus calms you down, giving you a tune in to the outside world. But during REM sleep, the thalamus is active and sends cortex, images, sounds and other sensations that fulfill our dreams. The pineal gland, which is located between the two hemispheres of the brain, receives signals from the SCN and increases the production of the hormone melatonin, forcing you to sleep in the absence of light.
People who have lost their eyesight and cannot use natural light to adjust their natural wake-up cycles can stabilize their sleep patterns by taking small amounts of melatonin at the same time each day. Scientists believe that over time the peaks and valleys of the melatonin are important for the body's circadian rhythm to coincide with the outward cycle of light and darkness.
The basal forebrain near the front and bottom of the brain also promotes sleep and wakefulness, while a portion of the midbrain, on the other hand, acts as an exciting system. Adenosine (a chemical byproduct for cellular energy use) from cells in the basal forebrain and possibly other regions accelerates your cycle of degeneration. Caffeine blocks the activity of adenosine in your brain and fights against sleep apnea. The amygdala, a nut-shaped structure that engages in your sensitivity, becomes increasingly active during REM sleep.
Sleep phase
There are two main stages of sleep : rapid eye movement (REM) sleep and non-REM sleep (which have three separate phases). Each is associated with specific brain waves and neuronal activity.
Usually you pass the REM and NONE REM periods every night. However
Increasingly longer, deeper RM periods occur in the morning.
Stage 1 - The change in sleep from waking is R-RM sleep. During these brief periods of relatively light sleep (lasting several minutes), your heartbeat, breathing and eye movement slow down, and your muscles sometimes relax. The waves in your brain begin to slow down from the awakening pattern of their day.
The second paryaya non-araiema sleep to light sleep, deep sleep period before entering. In this way your body temperature drops and eye movement stops. The activity of the brain waves is slow. You are more involved in this cycle of recurring sleep cycles than other sleep stages.
Third Stage - Non-REM stage is a period of deep sleep that wakes you up in the morning. This happens for a long time in the first half of the night. During this time your heartbeat and breathing remain at their lowest level. Then your muscles relax and you may find it difficult to wake up. The brain waves slow down.
The REM stage occurs about 90 minutes after sleep . When your eyes are closed, your eyes move quickly from the back of the eyelid to the other side. Combined frequency results in the brain's activity in the wake. Your breathing becomes fast and irregular, and your heart beat rate and blood pressure increase almost to the point of waking. Most of your dream REM trailers happen during sleep.
Although sometimes dreams can be made at non-RAM level. At this stage, the muscles of your arms and legs are temporarily paralyzed, which prevents you from achieving your dreams. As you grow older, you sleep less time in REM sleep. Both non-REM and REM sleep are required for memory consolidation.
Sleep mechanism
Two internal biological processes - Circadian Rhythm and Homeostasis work together while you are awake and asleep. Circadian Rhythm carries out a variety of functions including body temperature, metabolism and hormone secretion. These control your sleep time and help you sleep at night and make you more inclined to wake up in the morning without alarm. Your body's biological clock, which controls about 20 hours a day, controls most of the Circadian Rhythm . Circadian Rhythm synchronizes with environmental signals (light, temperature) to be aware of the actual time of day. But they persist even in the absence of a signal. Sleep-awake Homeostasis monitors your sleep needs.
Homeostasis sleep drive reminds the body to sleep after a certain period of time and controls the intensity of sleep. This sleep drive gets stronger with every hour you wake up and gives you longer and deeper sleep after a period of sleep deprivation.
Factors that affect your sleep-wake-up needs include treatment conditions, medicine, stress, sleep environment, and your diet. Light exposure has the biggest impact. The cells specialized in the retinas of your eye process light and tell the brain the difference between day and night, which can delay or delay our sleep-wake cycle.
Light exposure can prevent us from falling asleep or while sleeping. Night shift workers often have trouble falling asleep after going to bed and have trouble staying awake during work hours as they disrupt natural circadian rhythm and sleep cycle. In the case of the jet lag, the Circadian Rhythm moves away from compatibility over time when people move to a different time zone, creating a discrepancy between their internal clock and the actual clock.
How many hours do you need to sleep ?
Your sleep needs and your sleep patterns vary with your age. Sleep time can be different for everyone of the same age. Children initially sleep for 3 to 4 hours every day, which increases growth and development (especially in the brain). School-age children and adolescents need 7 hours of sleep each night. Most adults need 3-5 hours of sleep a night but after the age of 5 the night sleep is less and lighter. Generally, people are getting less sleep than they need to because of long work hours and twenty-four hours of relaxation and other activities. Many people think that they can get enough of their sleep deprivation on vacation, but that is not the case. We need to remember that regular sleep is not an option for adequate sleep.
What is a dream Why do people dream?
We all dream about sleeping . You spend about 2 hours every night dreaming , but most of you don't remember the dream . The exact purpose of this is not yet known, but dreaming helps you process your emotions. The events of the day often invade your thoughts during sleep. People with stress or anxiety are more likely to have nightmares. Dreams can be vital to any stage of sleep, but usually REM is most evident in sleep apnea. Some people dream of color, others in black and white colors only sbapnagulii can remember.
Can't sleep? What should be done for a good sleep?
Getting enough sleep is good for your health. Here are some tips to improve your sleep :
Set a schedule - Get in bed and get up at the same time every day.
Practice various exercises 20 to 30 minutes a day but a few hours before bed.
Avoid caffeine and nicotine at the end of the day and alcoholic drinks before bed.
Get comfortable before going to bed - try a hot bath or some other relaxing routine.
Make a room for sleep - Avoid bright lights and loud noises, keep the room at a comfortable temperature and do not watch TV or computer in your bedroom. Do not lie in bed while awake.
If you can't sleep, do something else like reading or listening to music until you feel tired. Contact a doctor if you have trouble sleeping or feeling uncomfortable during the day. Most sleep disorders can be effectively treated
What is the disease if not sleep?
Through research, I hope scientists will learn more about the effectiveness and control of sleep. The main focus of the study is to understand the risks associated with prolonged sleep deprivation and the relationship between sleep and disease. People who suffer from chronic sleep deprivation are more likely to be overweight, have a higher risk of stroke and cardiovascular disease, infections, and some types of cancer. Sleep disturbances are common with age-related neurological disorders such as Alzheimer's disease and Parkinson's disease.
There is a lot of mystery about the connection between sleep and these health problems. Does lack of sleep cause certain disorders, or do certain diseases cause sleep deprivation? These questions and many more questions about sleep represent the frontiers of sleep research.
