If you missed an entire night's worth of sleep how would you probably act and feel the next day?

Studies have shown that individuals deprived of sleep for 24 hours, brain activity decreases significantly (up to 6% for the whole brain and up to 11% for specific areas). In humans, sleep deprivation also results in a decrease in core body temperature, a decrease in immune system function as measured by white cell count and activity, and a decrease in the release of growth hormone. Sleep deprivation has also been linked to increased heart rate variability.

Keep in mind that everyone requires a different amount of time to sleep per day, so reaction to sleep deprivation may vary person to person.
