Much has been made in recent years of the damage which over exposure to sunlight can cause to the human body. The sun has been held responsible, with good reason, for conditions such as skin cancer, and too much sun can also cause the skin to age more quickly than it should. There is a balance to be struck though, and the sun can also do the human body a tremendous amount of good.
One major boost that your body can receive from you being out in the sun is a tonic to its production of Vitamin D. Conditions such as rickets can be the end result of the human body having too little Vitamin D, which is often as a result of not spending enough time in the sun. Some types of asthma and some varieties of cancer can also be caused by a lack of Vitamin D in the body.
The sun's rays act directly to initiate production of Vitamin D3, with UVB rays reacting with skin-based cholesterol to help the liver and kidneys manufacture the vitamin. This necessary process cannot happen unless we expose our bodies directly to light from the sun. Glass blocks out UVB rays, so sunbathing through a window does not have the same effect.
This means that taking a balanced approach to being in the sun can be very good for you. If you aim to be out for between a quarter and a half of an hour for four days a week, then you will be getting about as much as you need. Exposure to sun through glass does not have the same effect, because the glass blocks UVB rays.
The body also has its own natural protection mechanisms, which will protect people from overdosing on Vitamin D. It is also a good idea not to wash with soap too soon after coming in from the sun. This will wash off the skin's oils which are so important at the start of the Vitamin D production process.
There are other potential benefits to the skin being exposed to direct sunlight too, with recent research from Edinburgh University suggesting that exposure to sun may well help with circulatory conditions. Sunlight might help with illnesses caused by high blood pressure, as well as heart attack and stroke. This might well be so effective, the researchers claim, as to outweigh risks of skin cancers.
The active ingredient in the process of helping with conditions to do with the blood circulation systems of the body is the compound Nitric Oxide. This looks like it acts to lower blood pressure, though the authors of the study admit more research is necessary before it can be established beyond doubt. BBC statistics indicate that illnesses such as heart attacks and strokes usually kill 80 times more people than skin cancer on an annual basis.
So make sure that you get yourself out in the sun at least a few times a week this summer. It can help in at least two major way with your health. Speak to a medical professional if you have any problems with exposure to sunlight, or a more specific condition.
