Winters in several regions like Europe, the United States, Canada and some parts of the Middle East start by putting an end to Daylight Saving Time (DST). This is putting their clocks an hour back. Which happens somewhere around the end of October or the start of November. Thus it is brighter when majority of the people get up to start a fresh day.
This conclusively leads the afternoons to darken up quicker, limiting the outdoor activities of us humans thus harming our health and the environment thus making us lethargic.
To increase our outdoor activities and the intake of vitamin D the clocks, should not be put an hour behind as winters start.
Mayer Hillman from the Policy Studies Institute in Britain stated that it is almost impossible to find a source that benefits the health of humans without a cost. Also, that the sun is a very good source of vitamin D which is completely free of cost.
Vitamin D deficiency leads towards rickets thus being very dangerous. Approximately half of the population of the world has low levels of vitamin D.
A study by Hillman was organized in Scotland from which it was concluded that going from Central European Time to Greenwich Mean Time in the winters and increasing 2 hours in the summers gives 200 extra hours of daylight in a year.
Moving clocks an hour ahead in the winters can lead of an energy saving of around 0.3 percent of Britain on daily bases. This was the conclusion of a study which was published prior this year.
Elizabeth Garnsey, from Cambridge University who is an expert at innovative studies stated that this is comparable to the storage of about 450,000 metric tons of Carbon Dioxide during only the winters.
