As dawn breaks the first light triggers our internal body clock to wake up to the start of a new day.
Bright morning light and having breakfast fuel our body to begin the day's activities.
Cool white daylight encourages us to pursue outside activities such as a walk in the park.
When the sun is at the highest point in the sky we prepare to eat a healthy lunch with fresh vegetables.
Natural light levels change to a warm light and we recharge our batteries by enjoying lunch.
The warm sunlight counteracts the post lunch dip and motivates us to work outdoor in the garden.
During a sunny afternoon we can relax in the company of friends and enjoy a leisurely game of cards.
Good levels of daylight enable us to actively pursue our favourite hobby.
The early evening light creates a pleasant atmosphere to have dinner with a loved one.
When the last light of the day fades and artificial lighting is switched on, we contact family and friends.
The light levels in the evening can be set to create a cosy environment to sit and watch TV.
Good reading lighting improves contrast and colour to comfortably read your favourite book or magazine.
Turning off the lighting at the end of the day creates a dark environment for the body to relax and unwind in preparation for a good night sleep.
