Why is it that when I get less sleep I feel more awake during the day, but when I get more than a full nights.

There is such a thing as too much sleep.  Your body is remarkably good at self-regulating most of the time, but some times your "sleep barometer" gets thrown off for any number of reasons -- like cold/flu, minor depression, drinking too much alcohol, use of prescription/illegal drugs, the list goes on and on.  Best thing to do is to try and listen to your body.  If your body is telling you that you've had enough rest, then drag yourself out of bed (even if it feels like you're getting up too early).  If you're not feeling well or if you're just plain worn out for whatever reason, stay in bed and don't try to do too much or you'll get sicker or even more worn out.  Might take a little while, but you'll get used to listening to your body soon enough.

Me too! I don't know what causes it, but mornings are something that are rarely seen, but nights are great and energy filled.

Oh, yes, this is fun one.  What is happening is that sometimes when you are falling asleep, as your heart rate lowers and your muscles relax and your breathing slows, your brain thinks, just for a split second, that you are dying (you can see the similarities).  As a "check," your brain sends a test signal to your major muscle groups, causing them to spasm and you to jolt awake.  It is more likely to happen if your brain doesn't "think" you should be sleeping- like sitting up at a desk, for example, or if your internal stress levels are high at the end of the day.  I know it sounds crazy, but it really is a defense mechanism.  If you really were in danger, your body would not react to the test signal, and your brain would go into "fight or flight" mode to try and save your life.

lack of oxygen in the brain. it's a signal that you're mind and body are tired and you need to sleep to recharge.

during rem [rapid eye movement] sleep your brains nuerological transmissions are greater then when your awake,simpley put,it was / is an unresolved issue that your brain is trying to remedy!you have also been through a rather stressfull situation,moving quickley,etc.you could either contact him to get closure,or write down how you feel and answer your thoughts to yourself in writing,this may seem weird however this will help your active rem brain find resoulution with this matter! im from tennessee,i hope this helps you!!!

Lack of sleep is one cause.

a change in weather creates a difference in the hormonal secretion thereby affecting the mood.eg.in summer if the power goes off...the mind gets agitated.and in the winter u feel more sleepy.

Yes, I have the same problem. I don't sleep as much as I should, send me an email to hear about it.

Because when you need sleep is when you need more oxygen intake, and by yawning that brings in more oxygen.

Because you probably have a messed up sleeping schedule like me. You go to sleep late, wake up super early then take a nap somewhere in between which starts the cycle all over the next day.<yawn> <<<Did that help?

if you're falling asleep at 5am and waking up at 6 or 7 then yes, it's insomnia.  I know because I have it. BUT if you're falling asleep at 5am and getting a normal amount of sleep then your sleep pattern is messed up.  You'll have to force yourself to get up around 8am and you'll fall asleep earlier that night.

Late nights do cause weight gain.  As you get little sleep, you metabolism slows down, so you burn fewer calories.  Also, when people are awake, they tend to eat more.  There are many other factors.  Do yourself a favor, get some sleep.

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 suspect that what you mean is that the relative humidity is sometimes greater at night than it is during the daytime. This is because the air is warmer usually during the day, so it can hold more moisture.

Becuz since you don't feel sleepy at night ,, you try to stay up awake as much as you can,, so you fall asleep for a few hours then you have to go to work,, so you'll feel tired and sleepy becuz you didnt get enough sleep,, that's why you have to try sleeping earlier even tho you hate it,, so you'd have energy when you go to work :-)

It depends on what time of the day it is. if it is in the evening before I go to bed it relaxes me and I sleep good. If it is during the day it gives me a lift to get going and doing things. I really like it before I fall asleep. I sleep very well when that is the last thing I do before I go to bed.

you probably have allot less stress so you can sleep better at night and have a more positive attitude, which makes you feel sexier and younger. congrats!
