health benefits of sunlight
Everyone has heard of the many health benefits of sunlight. From promoting plant growth and improved plant productivity to maintaining human health and the visual quality of eyes, sunshine is vital for life on earth. There is also growing evidence to support the notion that too much exposure to UV rays from the sun may lead to skin cancer. Although there are no absolute signs pointing to the correlation between the two, more eye doctors and researchers are suggesting their patients to wear protective eye gear like sunglasses and other products designed to filter out UV rays. As far as long term damage to human eyes, the results are not entirely clear but the potential is certainly there.
In order to better understand the possible association between ultraviolet ray exposure and cancer or disease of the eyes, one needs to look at the vitamin D. Vitamin D is extremely important in terms of regulating the body’s metabolism and it helps maintain the health of bones and teeth. Vitamin D is produced naturally by our bodies and we can get enough through sunlight. The latest research suggests that excessive vitamin D can actually increase the risk of cancer in a way similar to excessive exposure to UV rays. Basically, what happens is that the body uses vitamin D to produce an excess of a certain kind of chemical called calcitriol. This chemical has been linked with various types of cancers including those of the prostate and breast.
It is not just the risk involved in overexposure to the sun that makes us sad. The health benefits of sunlight mean that the average person can safely participate in healthy activities without fear of harming his or her vision. For instance, people who Participate in indoor water park activities or go tanning lot or indoor tanning salon are much less likely to develop macular degeneration than people who stay home and avoid the risks involved. Of course, the more time you spend indoors the fewer risks you will be exposed to. The number of hours you spend in the sun also varies depending on your location – people who live in the desert or far north will see very little vitamin D in the air.
So what are the other health benefits of sunlight? As we have seen, the main benefit is the protection of our eyes and the protection of our skin from damage. It is not just the protection of our eyes that is gained – the skin and the immune system are also benefited. One of the additional benefits is the improvement in mental health and mood. It has long been known that the sun causes a release of certain hormones in the blood and these hormones are linked to our mood.
better immunity against bacteria and viruses
Some of the other health benefits include reduced risk of certain cancers and heart disease, as well as a stronger immune system. Other studies have shown that exposure to sunlight may reduce the occurrence of depression and certain types of cancer. Other health benefits include reduced stress, higher energy levels and better immunity against bacteria and viruses.
It is important to note that although all of these health benefits are great, there are some downsides to this form of treatment. For instance, exposure to the UV rays for an extended period may damage the eyes and cause retinal degeneration. Some people may develop skin conditions such as acne or eczema. Also, if you suffer from vitamin D deficiency or other deficiencies, you should take it into consideration before proceeding with this type of treatment. If you think you would benefit, why not give it a try today?
