does lack of exercise cause lack of sleep?

I say yes. My niece actually took sleeping pills because she could never fall asleep. She did NOTHING all day though. She'd lay on the couch or in bed and watch TV or talk on the phone. The family finally convinced her to get out and move around and she now sleeps just fine. Think about it, sleeping is the time when your body rests and recuperates. If you have nothing to rest or recuperate from, your body need to rest.

of course it is!  Any exercise is better than no exercise.  A good workout a couple hours before bedtime might help you sleep better too!

The best advice I can give you is to talk to your doctor about the problems you are having in your sleep patterns. Not being able to sleep can be a sign of a more serious underlying problem, mental or physical. \n\nYour doctor will know best how to treat your problem. He / she may prescribe you some short-term sleep aid medications to get you back on track or send you for further testing / further treatment. \n\nLosing sleep is a serious problem so don't let it go untreated or unnoticed for too long. Your rest level effects your entire existence and your state of mind. \n\nGood luck and best wishes...

exercise helps even if it is just walking... do not get too much sleep. Depression thrives when you get too little or too much.  Sleep is when your hormones in your brain regenerate...to much sleep to much hormone and vice versa.\ntry to find your trigger.

You need to sleep as much as possible since it is the only thing that you can't do too much. You can exercise too much, drink too much water etc. But you do not control sleep. If you do not need it, you can't do it. You can lie there but it will not happen. So sleep as long as it takes till you cannot sleep anymore.\n\nSee "fat loss tips" on below site for more on what sleep does for you.

Hmm, forgetfulness and low memory retention doesn't have to be due to restlessness in your sleep or sleeplessness.  Memory issues could be a sign of other medical conditions and you should see a neurologist to discuss and get a complete work up.  If it is sleeplessness you should have a sleep study done and see exactly what is causing the problem.  Sometimes sleeplessness is caused by underlying hormonal issues or depression or a chemical imbalance or not getting enough oxygen when you sleep..  Not have restful sleep is dangerous and can lead to other medical problems.  Get help before things become unmanageable.  People often wait to long to seek medical help and could have prevented certain medical conditions if they had sought help earlier rather than later... never hurts just to have things checked on.

It's best not to exercise within the few hours before you go to bed, because you'll be too keyed up to sleep. Exercise during the day and you'll be more rested at night.

Sure if you don't get enough sleep or you sleep too much, it will certainly have an effect on your health. \n\nNot getting enough sleep can make someone experiance symptoms associated with mental illness. It can also wear your body down so your immune system isn't as strong.\n\nI wouldn't think that changing your schedule would make much difference if you still got the same amount of sleep. There might be a period of time where you body adjust to the new schedule but it will get use to it eventually.

There are various factors that can lead to sleep deprivation. It may include hormonal control, beverages such as alchohol, caffeine, emotional status, weight (overweight have problems sleeping), external factors such as noise, grief, dreams and many others.

Lack of sleep can cause some extreme physiological and psychological changes, and lacking REM sleep (the stage in which dreaming occurs) can lead to such symptoms as personality changes, incresed anxiety and irritability, and impaired concentration.  This may not qualify as going crazy, but I'm sure such interruptions in a person's sleep schedule can make them feel as if they are going crazy.

when we do a lot of exercise,our body demands more energy.but the oxygen supply is not sufficient and hence in lack of oxygen,anaerobic respiration occurs in our muscles,which leads to the formation of lactic acid.this lactic acid causes "muscle fatigue",and our muscles starts paining after a vigorous exercise.

Sleep deprivation is a common condition that afflicts 47 million American adults, or almost a quarter of the adult population. Symptoms can interfere with memory, energy levels, mental abilities, and emotional mood. A study conducted by the University of Chicago Medical Center in 1999 indicates that the condition drastically affects the body's ability to metabolize glucose, leading to symptoms that mimic early-stage diabetes.\n\nSo why do we sleep? This is a question that has baffled scientists for centuries and the answer is, no one is really sure. Some believe that sleep gives the body a chance to recuperate from the day's activities but in reality, the amount of energy saved by sleeping for even eight hours is miniscule - about 50 kCal, the same amount of energy in a piece of toast.\n\nWe have to sleep because it is essential to maintaining normal levels of cognitive skills such as speech, memory, innovative and flexible thinking. In other words, sleep plays a significant role in brain development.  The brain's frontal cortex relies on sleep to function effectively. Again, insufficient rest adversely affects the frontal cortex's ability to control speech, access memory, and solve problems. The effect on physical energy is also startling: otherwise healthy people quickly show symptoms of age and early diabetes as glucose metabolism falls by up to forty percent. These physical reactions disappear when the test subject is allowed to rest properly. \n\nExhaustion, fatigue and lack of physical energy are common sleep deprivation symptoms. Exhaustion and fatigue affect our emotional moods, causing pessimism, sadness, stress and anger. The National Sleep Foundation (NSF) has suggested that social problems such as road rage may be caused, in part, by a national epidemic of sleepiness.

if you dont sleep enough, youll gain weight, you need a good amount of sleep in a good rhythm (about 8 hours are perfect for adults, children and teenagers need more)

If I didn't require sleep, I would rarely sleep at all.  I could work more hours, accomplish more things if I didn't have to sleep.  However, there is a time when life can get overwhelming and a good sleep to dream is a way to destress.  In that case, I would sleep occasionally for relaxing and dreaming.

Most human beings can go for 16 to 20 hours without sleep. After 20 hours, the first symptoms are usually listfulness, a noticable kinetic energy depletion in the extremities, lack of mental focus on complex activities, and irritability. A tendency for the eyes to droop and the head to become limp briefly are also indications. Operating heavy machinery (like driving) without sufficient sleep should definitely be avoided.\n\nMood swings tend to increase after a full 24 hour period without sleep is reached, and even the simplest of activities can become cumbersome. If the mind refuses to allow the body to rest beyond this period, the subject can display zombie-like characteristics. While, dementia, hallucinations, and increased levels of crankiness and irritability occur as a sleep-deprived person approaches over 48 hours without sleep.\n\nIt is believed sleep deprivation for more than 72 hours straight can lead to schizophrenia and irreversable brain damage. Although the scientific results are still inconclusive. \n\nThe record for the longest period without sleep is 18 days, 21 hours, 40 minutes during a rocking chair marathon. The record holder reported hallucinations, paranoia, blurred vision, slurred speech and memory and concentration lapses.\n\n- It's impossible to tell if someone is really awake without close medical supervision. People can take cat naps with their eyes open without even being aware of it.\n\n- Anything less than five minutes to fall asleep at night means you're sleep deprived. The ideal is between 10 and 15 minutes, meaning you're still tired enough to sleep deeply, but not so exhausted you feel sleepy by day.\n\n- A new baby typically results in 400-750 hours lost sleep for parents in the first year\n\n- One of the best predictors of insomnia later in life is the development of bad habits from having sleep disturbed by young children.\n\n- The continuous brain recordings that led to the discovery of REM (rapid eye-movement) sleep were not done until 1953, partly because the scientists involved were concerned about wasting paper.\n\n- REM sleep occurs in bursts totalling about 2 hours a night, usually beginning about 90 minutes after falling asleep.\n\n- Dreams, once thought to occur only during REM sleep, also occur (but to a lesser extent) in non-REM sleep phases. It's possible there may not be a single moment of our sleep when we are actually dreamless.\n\n- REM dreams are characterised by bizarre plots, but non-REM dreams are repetitive and thought-like, with little imagery - obsessively returning to a suspicion you left your mobile phone somewhere, for example.\n\n- Certain types of eye movements during REM sleep correspond to specific movements in dreams, suggesting at least part of the dreaming process is analagous to watching a film\n\n- No-one knows for sure if other species dream but some do have sleep cycles similar to humans.\n\n- Elephants sleep standing up during non-REM sleep, but lie down for REM sleep.\n\n- Some scientists believe we dream to fix experiences in long-term memory, that is, we dream about things worth remembering. Others reckon we dream about things worth forgetting - to eliminate overlapping memories that would otherwise clog up our brains.\n\n- Dreams may not serve any purpose at all but be merely a meaningless byproduct of two evolutionary adaptations - sleep and consciousness.\n\n- REM sleep may help developing brains mature. Premature babies have 75 per cent REM sleep, 10 per cent more than full-term bubs. Similarly, a newborn kitten puppy rat or hampster experiences only REM sleep, while a newborn guinea pig (which is much more developed at birth) has almost no REM sleep at all.\n\n- Scientists have not been able to explain a 1998 study showing a bright light shone on the backs of human knees can reset the brain's sleep-wake clock.\n\n- British Ministry of Defence researchers have been able to reset soldiers' body clocks so they can go without
