when we sleep our brains dont shut down but slow down.  we rejuvinate our brain causing us to think more clearly and be more preductive in just about everything we do.  It can effect the body in the long run.  Our muscles dont get the proper rest they require.  here are two links.  the first goes into great detail about what it does to the brain and the second is sleep deprivation fron diccovery.com

After you eat, a large portion of your blood goes to your stomach to aid in digestion. This can reduce the volume of blood going to your extremities and skin, making you feel colder.\n\nNot everyone gets cold after eating - it depends on the individual's circulatory system.

Reversing your day might seem fine at the begining but later on you'll start feeling tired and exhausted. Sleeping during the night is essential because it recovers your body completly and sleeping during the day doesnt have the same effect as it has during the night. I aslo know that growth hormones are secreted during your sleep at night, so if you dont get a good nights sleep your horomone secretions will be mixed so it will have a negative affect on you metabolism.

I think if you have a really hot or really cold bath it can make your heart beat faster so its not so easy to get to sleep. I always have really hot baths and i find this! But a warm bath is good for relaxing before bed.

Unfotunately, those new digital home thermometers are not very accurate.  But, if you stick with the old fashioned glass and mercury ones you will have better luck.  As far as your question goes, everyone's temperature varies.  From person to person and from hour to hour.  Depending on your health, your mood, your time of the month and the time of the day your temperature can vary.  Normal is 98.6 degrees Farenheit.  But, mine varies from 97.5 to 100.0 when I am totally healthy.  And yes, your temperature can drop when you are sick just like it usually rises when you are sick.  Hope that helps.

The heat you feel while having a hot flash (disgusting things!) is real.  During menopause, your body produces decreasing amounts of estrogen.  Because of this, the hypothalamus, which regulates the production of hormones, sends out GnRH (gonadotropin releasing hormone) in an effort to increase estrogen production.  GnRH also causes LH (lutenizing hormone) to be released.  One of the functions of LH is to dilate blood vessels.  This dilation results in increased body heat.  So, yes, it can register on a thermometer.\n\nIf you're underweight, you will feel it more.  Drinking a lot of water can help you maintain an even temperature.

There are several reasons body temperature can change quickly.  Hormonal upsets like hot flashes, lupus, illness/virus/infection/fever, thyroid malfunction all are causes.  Weather and exercise can also change temperature in the body.  Heatstroke and shock and make temperatures drop too.\n\nI would say, and I'm not a doctor, that you need to have a physical with a complete blood workup to test for thyroid, white blood count, lupus, and then go from there to see what the doctor thinks.

What's your body temp?

If this is concerning when you are sick--your temperature is rising.  And believe it or not--when your temperature breaks--or comes down, you will kick the covers off--you are too warm.  And if you are asleep when the temperature breaks, you will wake up wet with sweat.  Why, not sure, just mother nature (but I'm sure there is a medical explanation)  And if this is a prolonged high fever, you should not pile a bunch of covers on to keep warm.  This will just drive the temperature higher and help hold the heat in.

Its fine provided you keep your body temperature at an even level,and make sure you are secure and safe.Many doctors reccomend sleeping without underwear to let that area breathe!Its especially beneficial to use cotton sheets and allow your skin to get oxygen!As long as you keep warm enough in the winter and cool enough in the summer its fine! You want to make sure you are either alone or with someone you trust...and make sure your not too cold or in poor health or any medicial condition that gives you low body temperature.

Animal studies have shown that sleep is necessary for survival. The normal life span of rats is 2-3 years. However, rats deprived of sleep live for only about 3 weeks. They also develop abnormally low body temperatures and sores on their tails and paws. The sores probably develop because of impairment of the rats’ immune systems. \n\n\n\nIn humans, it has been demonstrated that the metabolic activity of the brain decreases significantly after 24 hours of sustained wakefulness. Sleep deprivation results in a decrease in body temperature, a decrease in immune system function as measured by white blood cell count (the soldiers of the body), and a decrease in the release of growth hormone. Sleep deprivation can also cause increased heart rate variability.\n\nFor our nervous systems to work properly, sleep is needed. Sleep deprivation makes a person drowsy and unable to concentrate the next day. It also leads to impairment of memory and physical performance and reduced ability to carry out mathematical calculations. If sleep deprivation continues, hallucinations and mood swings may develop.\n\nRelease of growth hormone in children and young adults takes place during deep sleep. Most cells of the body show increased production and reduced breakdown of proteins during deep sleep. Sleep helps humans maintain optimal emotional and social functioning while we are awake by giving rest during sleep to the parts of the brain that control emotions and social interactions.

No the body needs sleep in order to recoup. You can die without letting your body rest. If you get tired enough you'll pass out anyway..you will no longer have control over it

human's body temperature is 37 degrees celsius. below it you feel cold and above it you feel hot. Usually if you're above 37 you have a fever, but they asked if you have a fever then why you chill. Simply because the inner body temperature is above 37 and the outside body temperaute (which is usually the skin)below the inner body heat. So that's the reason why we chill.

Yes, it actually begins to slow 2-3 hours before bed time, as your body is preparing for sleep. And if you exercise first thing when you get up in the morning it will give it a boost all day long.

Yes, my hubby heard on the radio that it does.  I also feel that when you are asleep you cannot be eating.  The longer people stay awake the more they eat.  The less people sleep the fatter they get.  Americans have slept less and less and they have become more and more obese.  During sleep your body conducts a lot of healing and recovery activities.  With no sleep it can't repair the damage.  I don't know the exact mechanism why it helps you lose weight, but it came from a reputable source (NPR)
