What is the gland that courses sleeping?

the suprachiasmatic nuclei of the hypothalamus is responsible for circadian rhythms (basically our internal clocks).  the clock in the pons is responsible for basic rest-activity cycle and cycles of REM sleep and slow-wave sleep.

It replaces the neurotransmitter in your brain responsible for making you tired. It's the same chemical that is replenished when you sleep, so caffiene makes your body think you've slept when you haven't. If you take too much of it, it can be toxic - and habit forming.

you drink lot of water before going to sleep you will automatically wake up. self hypnotherapy will solve your problem.

The pituitary gland secretes hormones regulating a wide variety of bodily activities, including trophic hormones that stimulate other endocrine glands.

Do not engage in any type of exercise 2 hrs prior to going to bed.  Try a glass of milk- it contains a protein that helps you sleep. Avoid caffeine:teas,coffee,sodas etc.. Comfortable pijamas,idealroom temp,reading a book,aviod a great movie or show it will keep u stimulated.  Good luck!

The answer is (b) noradrenaline.  The adrenal medulla is the inner portion of the adrenal gland. The adrenal medulla secretes the stress hormones noradrenaline and adrenaline.

Biologists believe that during waking hours there are chemical changes (like harmful substances) and physical changes (wear and tear on cells) that are corrected when we sleep. Different stages of sleep are believed to have different functions. For example, REM sleep (when we dream) is believed to be when we consolidate learning and make memories. Slow wave sleep (the times when we are really quiet and not dreaming) is when restoraton is believed to take place. \n\nAs somebody said earlier, if we dont sleep we eventually die. Sleep deprived Rats became uncoordinated, lost weight due to climbing metabollc rates and appeared to starve to death though they were fed. Their immune functon was also compromised but cause of death was not really clear. \n\nMoreover, If you dont sleep you get haggard and ugly, its hard to concentrate, your family will eventually hate you for being a grouch and you will lose your job for making mistakes and telling off your boss. (if you dont kill yourself while driving to work first.) Everything is better with sleep :)

Any strenuous activity right before attempting to sleep will hamper that. Sleep is based on heartrate. I'm a caffeine addict, but I've found that caffeine can be flushed out of the system by drinking water, unlike alcohol. As well, if you place the bed in a room you are never in throughout the day, this makes it a more peaceful environment...Oh, and the room should be temperate.

G'day abouterachess,\n\nThank you for your question.\n\nDolphins sleep with half their brain switched on and with one eye open. They breathe normally as they are above water. They cannot breather until they are conscious.They decide to take naps at various times of the day and their body shuts down. They sleep for eight hours a day on and off. They have very little if any REM sleep associated with dreaming.\n\nThey have various options for sleeping namely:\n\na) swimming slowly and surfacing every now and then for a breath; or\n\nb) rest at the surface with their blowhole exposed; or\n\nc) sleeping at the bottom in shallow water and rising now and again to breathe.\n\nI have attached sources for your reference.\n\nRegards

Well, sleep is a period of regeneration.  Sleep deprivation, leads to decrease of brain metabolic activity, weakening of the immune system (i.e. drop in white blood cell count).  And in children the growth hormone is released during sleep.  Generally during sleep the rate of production in cells increases and their rate of protein breakdown decreases. \nInterestingly i can't remember where i read this, but the amount of sleep required for a species depends on their metabolic rate, and the metabolic rate increase as the size of the animal decreases.  So a mouse needs around 18 hours of sleep to regenerate properly, whereas an elephant needs around 3. But don't quote me on those numbers.

Pituitary gland\n\nThe most important of the endocrine glands (glands that release hormones directly into the bloodstream), the pituitary is located at the base of the brain. Sometimes referred to as the "master gland," it regulates and controls the activities of other endocrine glands and many body processes including growth and reproductive function. Also called the hypophysis.

The nasolacrimal duct.  The lacrimal gland is the gland above your eye that produces tears.  The tear duct causes the tears to exit next to the eye.  The nasolacrimal duct connects the lacrimal gland and the nose, so some of the secretions of this gland are taken to the nose.

Our body actually responds to it getting dark outside and releases a chemical called melatonin.  Melatonin is what gives you the sleepy feeling.  By the way if you have a hard time falling asleep, Melatonin is available at any vitamin and supplement store.  Its actually used alot for children with autism, to help them relax enough to fall asleep.

To answer this question you need to understand the sleeping stages.\nMany people think of their sleeping bodies as if they were cars parked for the night--motionless, engines off, headlights dimmed. But sleep is an amazingly complex state of being. As we sleep, muscles tense and relax. Pulse, temperature and blood pressure rise and fall. Chemicals crucial for well-being course through the blood stream. The brain, like a Hollywood director, conjures up fantastic stories, complete with a plot, characters and action. \n\nYou don't simply "fall" asleep. You descend slowly through different levels. As you close your eyes and drift off, you enter the first stage of what is called quiet sleep. Your brain produces irregular, rapid waves, and muscle tension decreases. You breathe smoothly, and mundane thoughts float through your mind. If roused, you might jerk awake quickly and deny that you'd slept at all. \n\nIn stage 2 of quiet sleep, your brain waves become larger, punctuated by occasional sudden bursts of electrical activity. You've definitely crossed the border between wakefulness and sleep. If someone lifted your eyelids gently, you wouldn't waken; your eyes no longer respond to stimuli. \n\nAs you descend into stage 3, your brain waves become slower and bigger. In this state of deep slumber, your bodily functions slow down even more. Finally stepping into stage 4, you reach deepest sleep, the most profound state of unconsciousness. On an EEG (electroencephalogram), your brain waves would appear extremely large and slow. You are so "dead to the world" that a thunderstorm might not wake you. \n\nThis step-by-step journey into oblivion usually takes more than an hour. Then you begin to climb upward, moving rapidly through the same sleep stages as before, not all the way to full wakefulness but in active sleep. Because the pupils dart back and forth, this stage is called Rapid Eye Movement or REM sleep. (The four stages of quiet sleep are often referred to as non-REM or NREM sleep.) \n\nDuring REM, your brain waves resemble those of waking rather than of quiet sleep. The large muscles of your torso, arms and legs are paralyzed, although your fingers and toes may twitch. You breathe quickly and slowly, the flow of blood through your brain accelerates. REM sleep is the time of vivid dreaming, and if wakened, you'd probably recall a fragment of a fantasy. \n\nAfter about ten minutes in REM sleep, you descend the sleep staircase again. The entire cycle of REM and NREM stages takes roughly 90 minutes. Early in the night, the periods spent in the deepest stages of quiet sleep are longer. In the second half of the night, REM sleep predominates. By morning, you go around the sleep circuit four or five times. \n\nThis pattern changes gradually throughout life. From infancy to adulthood, REM periods dwindle to less than a quarter of a night's sleep. By their thirties, men spend less time in the very deep stages of NREM sleep. Women begin to sleep less deeply in their fifties. By age 65, both sexes spend half as much time in deep sleep as they did when they were 25. The lighter sleep stages increase later in life, and REM shrinks to about a fifth of total sleep time.

There are a lot of considerations, like the amount of 'deep sleep' or REM (rapid eye movement) time.  It turns out that things like blood pressure and melatonin (hormone related to sleep) follow the diuranal cycle.  Yes, the sleep should ideally be at night.  That is how the human animal evolved on the planet earth.

warm milk and a coupla biscuits normally do it\n\nWarm milk helps production of melatonin.. the hormone that gets you to sleep.\n\nThe biscuits mix in with it as your stomach never likes to go to bed fully empty!
