People with depression often have hypersomnia, or excessive sleep, but still feel tired during the day. why might this be?

a. they tend to have less deep sleep and their rem sleep is less stable.
b. they tend to have no deep sleep, though their rem sleep is more stable.
c. they tend to have more deep sleep and their rem sleep is less stable.

i think it's they tend to have more deep sleep and their Rem sleep is less stable.

because you are not supposed to sleep more than your normal sleep time so if you over sleep you will still be tired if you get to less of a sleep then you are going to be still a little tired just not as much if you were to over sleep

i need the a b or c but mental disorders include repetitiveness,unable to listen, wanting to kill people, thinking that you are perfect, sexuality toward the wrong age types younger than you like a child bad reputations cutting yourself abuse! these are sad but these are true! the titles for some of these are ptsd and adhd. you need to go to jail or get an expert counselor if you face any of these problems or if you have indeed been involved!
