what did you dream about
what is the oldest dream you can remember
6:39 oneone: astronauts can't sleep due to a gravity disturbance our bodies are designed to function with gravity flushing toxins out of the body and pumping blood in the correct direction and getting the right amount of signals through the blood/brain barrier
6:40 - Floki: gravity doesn't pump blood
6:40 - Mr_Sir: i immediately thought that too when i read the article
6:40 - Luna Prey: then how do they sleep on the iss
6:40 - ret: Our eyes are always the same size from birth, but our nose and ears never stop growing.
6:40 oneone: but blood uses gravity with bigger blood vessels
6:40 - ret: In Utah, it is illegal to swear in front of a dead person.
6:40 oneone: they only manage to sleep for 5 hours on iss
6:40 oneone: i am just mentioning why they can't get anymore
6:41 - ret: we need more useless facts
6:41 oneone: their brain is functioning without the correct signals passing through the blood-brain barrier due to there being no gravity for control of how much blood gets there
6:42 oneone: the body uses more vitamins to try and function when there is toxins in the blood
6:44 oneone: if there is no gravity for assistance of flushing toxins out such as water is stored in the legs we lay down and legs shifting positions causes gravity to help the blood pump that extra water to flush stuff out
6:44 oneone: anyways
6:44 oneone: that would be a likely reason why they can't get enough sleep because their body is stressed compensating from no gravity
From the "Did you know that psychopaths don't dream" thread:
I used to dream when I was much younger. But now I exhibit symptoms of what you've described above (Waking throughout the night and feeling exhausted after a full night's rest). 8 hours of sleep feels like 2 hours of sleep, and 2 hours of sleep feels like 2 hours of sleep, so I generally just sleep 2 hours to avoid wasting valuable time in unconsciousness. I do not dream anymore (I guess an argument can be made that I simply can't remember the dreams), at least, visually. I recall "hearing" incoherent sounds, ones that aren't really imaginable, during my sleep. Maybe, once or twice, have I actually heard a coherent sound in the past many years. A friend of mine told me I seemed like I was a narcoleptic, but narcoleptics are noted as VERY vivid, and constant dreamers. I fall DEEP into sleep VERY quickly, compared to the people around me (I slept through my house being on fire, shortly after I fell asleep AND the Fire Department putting the fire out), much like a narcoleptic. I have fallen asleep mid-day, in the middle of holding things, for example. But this has been a somewhat recent development. And, these sleep attacks can also be due to the sleep deprivation associated with my insomnia. However, insomnia does not explain the quick sleep cycles.
I recall having a few vivid dreams when I was much younger, but most of the time, if I remember correctly (I usually don't), they mostly consisted of a single image or sound (Only that image/sound for the entire night. As in, that would be the ONLY thing I would experience, for that moment, and the rest of the night would be completely devoid of dream activity.).
yes to low vitamin B
that is what causes most sleep problems
and untill you start regularlly taking it
then you can't claim you don't need it
even if you don't lack it..it's still helpfull -.-
there is also drugs that help you sleep which have s side effect of vivid dreams
