Neither: Typically when you sleep the eyes are closed so it doesn't much matter if the air in the room is hot or cold. Eyes can drift open at night in some people, which can allow them to dry out overnight. Over-the-counter artificial tear ointments at bedtime are helpful to keep the eyes lubricated at night in these cases. Nonetheless, you need to see your eye doctor to determine the cause of your red eye.
