We don’t always think about how light impacts our physical and mental health every day. It’s just… there. But like good quality air, water and food, we need the right kind of light at the right time of day (light nutrition) to be happy, healthy and productive all year round.

When we don’t meet our light nutrition needs, problems such as sleep disruption, Vitamin D deficiency, Seasonal Affective Disorder (SAD) and the Winter Blues can negatively impact our health, work and relationships.

Light nutrition for individuals.

How much light we need, the type we need and at what time of day is what we mean by light nutrition’. It’s individual to you, so we encourage you to live your light ideal to build and protect your own and your family’s physical and mental health all year round.

Some factors that can influence your individual light ideal:

Your chronotype

Whether you’re an early bird or a night owl, or somewhere in-between

Your environment

The natural and artificial light you’re exposed to where you spend your time

Your geography

Where in the world you are and its weather patterns

Your seasonality

How sensitive you are to changing seasons

Your demographics

Your gender, age and race
