	People have circadian rhythms linked to the natural light/dark cycle of the day. These control patterns of alertness and sleep as well as other factors such as body temperature and the release of various hormones. Light and dark patterns act as the most important signal to entrain (synchronise) the circadian clock to the solar cycle and cause waking and sleeping to occur at consistent times.

Light at night time can alter the body clock, suppressing melatonin production and keeping people awake at night, and making them more sleepy during the day.

	Circadian lighting varies in colour and intensity during the day. The aim is to improve alertness during working hours using bright light, but to switch to lower brightness, warmer coloured light before it is time to relax.
