Summarize the following:
Okay, this isn’t exactly staying up all night, but taking a nap for even a few minutes can improve performance and minimize signs of sleepiness. Even a little shut eye can help you stay up for the rest of the night.  One study found that people did better with just a 26-minute nap. So shut your eyes for just a little bit, and you should find it easier to make it through the entire night and next day. The key here is to take a short nap because otherwise you could end up in a deep sleep, which is very hard to wake out of. You could also sleep a little bit longer the night before you know you will be up all night. The body will “bank” the sleep, and it will be easier to get through the stretch of sleeplessness without it. Your body clock is actually aware of changes in light and darkness, and you will feel more awake in the light. The body clock is linked physically to the eyes.  If you’re super tired the next day, go outside. The sunlight will also function to wake your body up more. The darkness causes the body to produce melatonin, which is the sleep hormone. People’s instinct is often to turn down the lights at night, but that’s probably going to make you more sleepy as the body perceives it’s time to call it a night. Turning the lights higher than normal will trick the body. The brain is going to be more alert after you move a bit. If you don’t have time to exercise, you could just engage in a conversation, wash the dishes – do something to focus your body on a new action for a time.  Changing an activity also might wake the body up more. The body will become more alert to compensate for the new activity. The body feels less tired when you’re busy because it will focus on the task instead of the lack of sleep. Mental activities also may help you stay awake by keeping your focus on something other than the fact you're tired. So try playing a game. Some mental activities, like reading a book, may make you more sleepy, though, especially if you do them while lying down. You could listen to a talking radio show though. The body temperature naturally lowers during sleep, so people sleep better when it’s colder. However, a hot room is probably going to make you feel drowsy.  Other ways to trick the body into feeling more wakeful include taking a cold shower and getting dressed up for your day. In addition to turning down the room temperature, you could also open a window. The breeze should help you stay awake, in addition to the lower temperature (if it's cool outside).

Summary:
Take a short nap during the night or right before it starts. Make sure the lights are on and bright. Stay busy, and move. Cool down the room.
