Window good for your soul

LONDON: Sitting by a window at work may lower your blood pressure and make you more alert.

A trial by Cornell University in the US studied 30 nurses, some of whom had windows by their workstations. These nurses had slightly lower blood pressure, felt less sleepy in the morning, communicated better, laughed more and drank less coffee during a shift. The researchers concluded that being exposed to natural daylight had a positive effect on the body clock, based on differences they observed in body temperature, which plays a part in regulating internal rhythms.

This may account for the other positive changes, such as improved blood pressure. – Daily Mail
