Light Up Your Life

Seasonal affective disorder, or SAD is what happens when people who don't get enough sunlight during the winter feel depressed.
So does extra light make you happier?
It does, says the journal Psychiatry and Clinical Neuroscience. And you don't need a whole lot to make the difference.
Researchers at Sapporo Hanazono Hospital in Japan studied the effects of one hour of bright light every morning on a group of elderly women.
After two days, the women reported improvements in alertness, mood, motivation, happiness, refreshment, concentration and appetite.
After four days, there were also improvements in sleep patterns and anxiety.
By the end of the month, they reported higher electric bills!
