The central star of the solar system, the sun, consists of chemical elements particularly hydrogen and helium. The sun is endowed with a powerful magnetic field and thermal radiation. It has tremendous benefits of producing supply of Vitamin D which will greatly help our bodies in responding to immune system and bone health. Although most vitamins may be obtained from nutritious foods and vegetables, Vitamin D may be acquired through photosynthesis activated by radiation of type B ultraviolet or (UVB). The production of vitamin D relies on the UVB photons being emitted by the sun to the skin. This natural process varies since every person wears different set of clothing, applies sunscreen creams and holds varying levels of melanin aside from body fat. The sunlight generates an estimated average of 20,000 IU (international units) in tanned people while black colored skin individuals may obtain approximately 10,000 IU. Fair skinned individuals get the most IU about 50,000.
Vitamin D is highly significant to one’s health. It largely contributes to the formation of strong bones by calcium absorption. Latest research presented that vitamin D may deter some types of cancer including colon, prostate and breast by helping the liver eliminate toxins. It may also be a natural remedy for jaundice or yellowish skin discoloration due to hyperbilirubinemia. Exposure to sunlight helps prevent people from experiencing osteoporosis and diminishing the incidence of getting back pains. The sun offers a wide range of benefits due to its natural production of vitamin D. Devoid of sufficient vitamin D in children results to rickets which is the most common childhood disease characterized by softening and weakening of the bones causing deformity. Additional studies from Boston Health Care Clinic have shown that the said vitamin also aids in neuromuscular transmission and metabolism. Sunlight also serves as an antiseptic in which its powerful rays destroy fungi, bacteria and viruses that may appear on your skin’s upper layer. In relation to this, sun exposure helps people avoid acquiring athletes’ foot, eczema, acne, psoriasis and boils. Healthy blood circulation and production of white blood cells for better immune system are considered pleasant advantages of sun exposure.
According to the research of anatomy department of UCLA Medical School, overexposure to sunlight may cause ocular problems particularly blindness and impaired vision. A winglike, non-cancerous growth on the conjunctiva of the eye which is popularly known as pterygium happens to be another kind of optical problem triggered by too much ultraviolet exposure and dust. Snowblindness or photokeratitis is another ocular problem caused by the sunlight. Redness, hazy vision, pain and headaches are some of photokeratitis’ symptoms. Sunburn and skin cancer are the most prevalent risks of sunlight exposure. Other studies showed that cataract may also result from overexposure. In general, sunlight may provide advantages and disadvantages to a person’s health conditions.
