If I go to bed early will my body feel better?

Yes lot people are feeling that need to get more sleep , my cousin went to bed early tonight cause she said , she was feeling tired plus our older cat whose age 22 is not doing so good, my cousin is always waking up during the night to check on the cat , the cats name is cotton she is all White , my cousins been with her for many years so she's taking this hard . We may need to have her put down so will have to see what goes on here , i feel bad for Cotton but if you feel the need to get more sleep than most certain do it ?
