Essentials of Sunlight

In this cancer-phobic society that we live in today, many things that are known to cause cancer get a bad name. The experts will tell you that all the people that flock to the beaches for the sunshine only get a sunburn and the risk of skin cancer. But is this all that our Sun’s light is good for? A closer look at what sunlight does for us is an incredible eye-opener to the wisdom of the creator and the incredible world around us.

An important thing to note is that the Sun’s light can indeed have some bad effects on us. Being exposed to ultraviolet light can be harmful. But even though the Sun produces radiation, the level of radiation is stopped by the Earth’s atmosphere; although not as much as at the time of the original creation as our atmosphere has decayed over the past 6,000 years. Even so, the Sun’s radiation is not nearly as harmful as that of your router or cell phone.

One important factor that we all know the Sun for is photosynthesis. When we breath, our lungs take in the oxygen that is in our air. This carbon dioxide is then taken by plants and converted into oxygen through a process called photosynthesis. sunlight is an important part of this cycle. Without sunlight, we wouldn’t have sufficient oxygen to breath!

But plants aren’t the only ones who get benefited from sunlight. Sunlight is important for the human body as well. Remember the sun vitamin or vitamin D that we were always told about? You may not know how important this is for your survival. When we eat fat, some of the cholesterol goes to the brain and heart (which is good for both but I don’t have time for that right now; Maybe some other article) while some of it stays in your blood stream. Then when sunlight hits your skin this cholesterol is converted into Vitamin D. From there it is taken to the liver and converted into Calcidiol and then biologically activated into calcitriol in the kidney and helps with bone growth and health. Vitamin D has also been known to help with immune functions and emotional stability.

So in the end, what have we learned? Don’t stay inside; you will die. Despite the fact that we are living in a fallen creation, we still see traces of the original perfect creation all around us. Our creation is filled with many amazing things that without which we couldn’t survive. Sunlight is just another example of how our universe could only have come from an intelligent creator.
