In
Canada, summer weather can be fleeting. I tend to soak
up as much sunshine as I can in those few precious months. Exposure to
sunshine triggers the production of vitamin D, which is essential for bone
strength and regulating calcium levels. New research shows vitamin D may
even
slow cellular aging
. In addition, sunlight increases the brain's production of serotonin, a
hormone linked to improved mood and feelings of well-being, which is why a
lack of sun can contribute to seasonal affective disorder. While a
moderate dose of sunshine is beneficial, it is important to balance it
with sun protection to avoid the risks associated with too much UV
radiation.
