Quesitons dealing with the brain and sleep.?

Question

Okay, my questions are:
1. Is there a possibility for someone to not have a circadian rythm, and only sleep when physically exhausted?
2. Is it normal for someone to be able to sleep 12-14 hours every night if allowed and not have a sleeping disorder?
3. What should someone do if after they wake up, they always feel tired still, even after sleeping for 12 or more hours?
4. And is it possible to have a problem with your hypothalumus, or another part of the brain if you start to sweat, and lose apetite when you do something simple such as sweeping a floor, or even brushing your teeth?

Answer 1

1. There are a class of sleep disorders called "phase disorders" that give people unusual sleep patterns, making them stay up very late until they drop or wake up in the middle of the night. There are also people who genetically require very little sleep overall, though this can be dangerous in later life as it can lead to a syndrome called "Fatal Insomnia."
2. Sleeping that long is not such a good sign. Could be a sleep disorder...OR it is a symptom of another health problem, like depression or even dietary problems.
3. This is very much a symptom of narcolepsy. People often have the wrong idea about this disorder. Only some people collapse randomly, more often they're just constantly drowsy.
4. Have not heard of this problem, other than hyperhydrosis (excessive sweating). This could be a blood sugar or blood pressure problem too.

Answer 2

Some endocrine disorders (aka "hormone problems" or "glandular problems") are associated with fatigue, sweating, and appetite changes.

If these symptoms are present and problematic, and not just a mild curiosity for you, you should talk to your/a doctor about it. There are some really simple tests (bloodwork) s/he can do. At the very least this will help rule out what it isn't.

Answer 3

1. Every one has one... everyones differant
2. You can sleep for that long. I feel that after 6hours of sleep I get "too much" - BUT THATS ME, WERE DIFFERANT -
3. Talk to your doctor - you might feel wierd about talking to your doctor about strange things, but think about it... he is a doctor, he hears strange things all the time (I used to work in a Hospital - holy crap -)
4. Again, back to my answere for number 3, these questions could all be answered by a doctor. They might need to run some tests but I wouldnt worry about that till the doctor says something is wrong. Good Luck.

Answer 4

1. no because without circadian rythm you'd be dead
2. yes .. in very rare cases a person can sleep even 16-18 hours per day
3. should go to a doctor
4. may be... go to a doctor and find out!
