Does sunshine make us happier and healthier?
In many parts of the world,there’s a deeply ingrained（根深蒂固的）belief that sunny days make us feel more cheerful.
It seems like common sense.but scientific evidence is not surprisingly equivocal（模棱两可的、不明确的）.Researchers reported that people surveyed on sunnier days felt more satisfied with life than people surveyed on cloudier days.
But,an earlier and large influential paper involving over 1000 volunteers found no evidence that people enjoyed more positive moods(although they did tend to feel less tired)
Flipping things around（扭转乾坤），even the idea that many of us are more prune to depression in the gloomier the winter months is controversial.
In short,the evidence of the mood-enhancing effects of sunshine is not as robust（坚固的、强壮的） as you think.
When it comes to sunshine and health,the scientific evidence is clearer.Sunlight exposure is beneficial in many ways.because it allows the body to create vitamin D,which can reduce the risk of cancer and lower blood pressure.
