How does sleep deprivation cause a lack of energy?

In terms of physiology and biochemistry, why does a lack of sleep cause a lack of energy?

Yes the body and brain need time to rest and recuperate, but how exactly is this related to energy?

I lost my short term memory and thinking abilities from prolonged sleep deprivation. What can I do to restore my brain’s original state? Did I already do damage to my cognitive functions? It is irreversable?

About two weeks ago, I began having heavy problems with sleeping. It has dropped from the usual 6-7 hours first to 5, and now I barely even manage to get 3 hours! Last night I first felt asleep for 1 hour, then I woke up in the middle of the night, I felt like my brain won’t let me sleep, and I felt nervous, so I tossed and turned for about 2 hours in order to get another 2 hours of sleep. I feel extremely bad, I am sweating a lot, I feel like my balance is a bit messed up, and sometimes have mild muscle contractions. It all came out of the blue, for no reason at all. I wasn’t under any stress

Is this sFI possibly? Or just a normal insomnia? I am 20 years old, and I heard there were some cases of this in their 20s.

Shouldn’t the neurotransmitter melotonin cause me to be more sleepy during the night? Is my brain messed up?

Im a 15 year old male and for a period of about of month my sleep patterns were screwed up due to anxiety and thinking. For some of the days I was laying in my bed with my eyes closed but I couldn’t fall asleep at all and I was aware. Other days I may have gotten only a few hours of sleep. Since then I’ve been doing better and I’ve been getting a full night’s sleep every day but now I keep worrying if the lack of sleep I went through may have permanantly affected my brain.

Looking up sleep apnea it says "brief periods of recurrent cessation of breathing during sleep that is caused especially by obstruction of the airway or a disturbance in the BRAIN’s respiratory center". I had never heard of the brain’s respiratory center or anything remotely similar. What does it mean? How does it help humans (and probably animals)?

I would appreciate any information since a family member hospitalized for aggravated COPD, and CHF among others (pneumonia especially) keeps having trouble sleeping and her breathing is worse than yesterday.

My Son has a deep sleep disorder which means he spends most of his sleep cycle in very deep sleep. This reduces the amount of oxygen to his brain, gives his body a great relax and boost of energy but does not rest his brain, so he is mentally tired and finds it difficult to concentratete and to control all the extra energy his body has. Does any one have experience with dealing with this?

Can sleep deprivation help in a weird way?

Sleep deprivation has been known to cause hallucinations, and basically make, said person, go insane..after 70hrs without sleep a person’s brain will shut itself down in attempts to "recharge" itself, while the person is still awake, making it difficult for someone to distinguish what’s real and what’s not. So the question is, would pushing yourself to the edge of insanity bring some "enlightenment" to a person if they were to attempt it? A better understanding of what being "insane" is really like, possibly?

I’m talking about depression and schizophrenia mainly. It’s been documented that people who are deprived of sleep for long periods of time will show symptoms of psychosis, and people with depression tend to sleep in longer and feel fewer symptoms when they are well-rested. Could the conscious behavior of the mentally ill be symptoms of prolonged improper sleep, as if only a part of their brain had chronic insomnia and was the source of the malfunction?

sleep deprivation?




what occurs in the brain during sleep deprivation? Some years ago I was unable to sleep for more than a couple of hours at a time, actually due to excitement and after about a week of this I became near hallucinatory and felt depressed and horrible.

Yeah, so last summer I got into the habit of getting drunk and taking benzos practically every day. Usually xanax or klonopin, but sometimes valium and ativan. imovane sometimes, too, but that’s not a benzo. I don’t think that I feel any weaker than I used to, but I’m wondering if about five months of abuse could have some detrimental effect on my heart or brain.
