The importance of daylight for our bodies

Daylight is vital and has a significant influence on our health and wellbeing. It controls our biorhythm, our hormone balance, our mood and our sleep. We often only realise how important daylight really is to us when we lack it. If we receive too little natural light and sunlight, the risk of health problems and mood disorders increases. Not only is daylight essential for humans, but the animal and plant world also needs light. It is the energy source for all organisms. Without light, for example, plants could not photosynthesise and produce oxygen. Animals would not be able to develop a stable day-night rhythm without the natural change of daylight and darkness. Without sunlight and natural daylight, no life on earth would be possible.
