What is weather?
Life on Earth depends on solar radiation as an energy source and has adapted biologically to the day/night rhythm as well as to the seasons. The sun enables photosynthesis, without which there would be no life. It causes cloud formation, ocean currents, winds, precipitation and air pressure fluctuations, which we summarize under the term weather, without normally thinking about their manifold biological effects.
The type, quality and quantity of our plant food directly depends on the seasons and climates, as well as their amount of vitamins, antioxidants, minerals, phytochemicals and valuable trace elements.
In the course of evolution, the metabolisms of animals and humans is very closely linked to these vital substances of plants, or are existentially dependent on them. Without chlorophyll and related substances that convert sunlight into chemical energy, there would be no life on Earth. The broad spectrum of sunlight ranges from warming infrared radiation, to the range of rainbow colors visible to us, to the ultraviolet range.
This spectrum changes during the day due to the position of the sun and the different thickness of the atmosphere that scatters the short-wave light, which is why the sky appears blue. This cyclic color change represents a kind of biological clock for all living beings that align their activity accordingly.
The weather therefore has a great influence on our biological functions.
