One of the primary reasons why airplane cabins are kept cool is due to the altitude at which planes fly. The air temperature at cruising altitude can be as low as -70 degrees Fahrenheit, which means that the cabin must be kept at a low temperature to ensure that passengers and crew members are comfortable.

Time your sleep and drinks Assuming you're adjusted to the time zone the flight departs from, daytime flights will make sleep on board much harder, whereas nighttime flights make sleep easier. All humans have a circadian (24-hour) time-keeping system, which programs us for sleep at night and wakefulness during the day.

Whether flying at night or during the day, pilots need to see some kind of horizon. They use this to determine the airplane's attitude. At night pilots will turn their gaze from outside to inside and use the artificial horizon. The artificial horizon is normally a simply globe split into two hemispheres.

Planes have headlights so that pilots can see what is in front of them. Unfortunately, they are only effective during takeoffs and landings. Even with the slight illumination offered by the headlights, only darkness is visible when looking out the front window of a cockpit.

Nighttime or morning flights are statistically better for turbulence, compared to those in the day. Although turbulence can't be completely avoided at night, winds are often weaker and thermal convection turbulence is less, making the chances of encountering turbulence reduced.
