Yes, Angie, I think the day length would be - if a problem at all - a minor one compared with, for example, . . .
(1) lack of sunlight. Mars is farther away from the Sun, and it's not as though you'd get much sunlight through a space suit.
(2) lack of oxygen. A serious problem not being able to breathe except in enclosed spaces where oxygen could be generated.
(3) dangerous radiation. Mars doesn't have a magnetic field to deflect dangerous particles in the solar wind.
I don't think I have qualities that would help me live on Mars. Except that I wouldn't mind having the extra 37 minutes in a day. Don't think I'd spend them sleeping.
