Scientists say that putting clocks back in winter byending Daylight Saving Time (DST) and putting their clocks back by an hour is bad for health, wastes energy and increases pollution. They say that leaving clocks alone as winter approaches would allow an extra hour of daylight in the afternoon and could boost levels of vitamin D as well as encourage people to exercise more.
Britain and Russia politicians are being asked to consider parliamentary bills suggesting it's time for a change. "It must be rare to find a means of vastly improving the health and well-being of nearly everyone in the population -- and at no cost," said Mayer Hillman of the Policy Studies Institute in Britain, where a bill on DST is coming up for consideration in parliament soon. "And here we have it."
A study published earlier this year found that advancing clocks by an hour in the winter would lead to energy savings of at least 0.3 percent of daily demand in Britain. Elizabeth Garnsey, one of the study's authors and an expert in innovative studies at Cambridge University, said this was equivalent to saving 450,000 metric tons of CO2 during winter alone.
