What makes us sleep at night?
The sleep-wake cycle consists of 8 hours of nocturnal sleep and 16 hours of daytime wakefulness in humans. This is controlled by a combination of two things. Sleep homeostasis and circadian rhythms.
The circadian rhythms is the cyclical changes like fluctuations in body temperature, hormone levels and sleep that occur over a 24 hour period driven by the brains biological clock. This rhythm is affected by light and darkness. Basically this keeps us awake while the sun is out, but prompts us to sleep once it becomes dark. (Source)
