There's been a bit of a vitamin D revelation in the media recently, with it being heralded as a cure for depression, preventing cancer, bolstering the immune system, strengthening the body's skeletal/muscular structure and protecting the brain; the list goes on.
The most efficient means for vitamin D adsorption into the human body is through exposure to the UVB rays present within sunlight. The danger of becoming deficient in the 'sunshine vitamin' is far greater during the darker winter months, when daylight hours are greatly reduced. For this reason, many people take supplements and find alternative 'sun' sources between the months of September and April.
Here are three key ways to keep yourself out of the vitamin D deficiency danger zone this winter.
As always, getting a good range of minerals and vitamins through your diet is fundamental to your overall health. In the case of vitamin D, oily fish, milk, eggs and liver are particularly good sources. Mushrooms are a great vegan option and if they are exposed to UVB light, the vitamin D potency is increased by a considerable amount.
While supplements are rarely as effective as natural sources, sun exposure in this case, they can help to alleviate deficiencies where necessary. Taking a vitamin D supplement during the winter, when sunlight exposure is minimal or non existent, can make a big difference to your health.
Find a light source
The effect of the sun's light being adsorbed through your retina and skin can be replicated to a certain degree. There are a wide range of lamps for combating SAD available on the market; from ones that sit on your desk, to ones that you wear close to your eyes. It's important to research these products before you use them, as they vary in quality and effectiveness.
