Have you been feeling sad, depressed, indifferent? Well, perhaps there is a reason for your sense of underwhelming.
Regular exposure to sunlight makes us more active, happy, and alert. The less sunlight we are now seeing in the winter months, for those of us living in the Northern hemisphere, the more likely we are to develop Seasonal Affective Disorder (SAD). Symptoms of SAD can include mood swings, anxiety, sleep problems, or in the most extreme example, even suicidal thoughts.
Our body develops Vitamin D when exposed to sunlight. A lack of Vitamin D can lead, not only to depression, but also to bone pain, muscle weakness, cognitive impairment in older adults, asthma in younger children and even cancer.
So if you are not getting enough exposure to sunlight, make sure you get your Vitamin D in other ways, either as a supplement or in foods. Foods which provide Vitamin D are: cheese, egg yolks, shitake mushrooms and cod liver oil, fatty fish; such as tuna, mackerel, and salmon.
Often foods like some dairy products, orange juice, soy milk, and cereals are fortified with vitamin D.
So make sure you are getting your Vitamin D.
