Sunshine

Notes based on Tony Buzan's Book of Genius published by Random House 1994

Light somehow reaches into the brain and stimulates our thoughts and emotions. We need a daily ration of light. Ultraviolet radiation in sunlight enables the skin to synthesise Vitamin D.

A common problem in countries with high altitudes, eg Canada or Scandinavia, is Seasonal Affected Depression or SAD for short. This causes depression due to the reduced hours of daylight in the winter months.

Light somehow reaches into the brain and stimulates our thoughts and emotions. Studies reveal that our bodies need to be exposed to full-spectrum light (i.e. sunlight) - not just the few parts of the spectrum radiated by most lamps - if we are to feel energetic and to perform at our best.

We need a daily ration of sunlight. If you are working inside all day, then you should spend part (or all) of your lunch break in the sun.

Ultraviolet light enables the skin to synthesise Vitamin D. Mood and performance suffer when a person's doses of light are either too little or too irregular.

The timing of our light doses is important too. That's why sunrise and sunset have an influence on human behaviour, in particular for night shift workers, and jet travellers (jet lag).

Get out of doors early and late in the day and open curtains to let the sunshine flood in. Melatonin levels go down, and spirits and performance go up.
