Despite the Kingdom being among the top countries in the world in terms of exposure to sunlight, Saudis ironically suffer from a severe lack of vitamin D, of which the sun is a natural source.
This was revealed by Nasser bin Mohammed Al-Daggrey, supervisor of Prince Miteb bin Abdullah Center for Research in Biomarkers for Osteoporosis. The average sunlight in the Kingdom is an estimated 2,200 kWh per square meter, due to its location on the earth’s sunbelt.
Al-Daggrey said the importance of vitamin D lies in its ability to absorb calcium and phosphorus, which are nutrients that play a prominent role in protecting human bones and the strength of muscles, as well help fight diseases such as colon cancer, breast cancer, heart disease, Type I diabetes, and the common flu.
Many Saudis suffer from severe vitamin D deficiency due to lack of exposure to the sun on a daily basis. Prolonged stay indoors or in places away from sunlight, the use of shades on vehicle windshields and consuming junk food low in nutrients all contribute to this deficiency.
Al-Daggrey said vitamin D deficiency in humans is identified through various symptoms such as pain in the muscles and bones, especially in the lower back, chronic headaches, or neck pain. Other psychological symptoms that signal deficiency include depression, fatigue, increased muscle aches, sleep disorder, poor attention and concentration, memory impairment, a feeling of fear, high irritability and sexual dysfunction.
He pointed out that the best time for sun exposure to maximize vitamin D absorption is between 9 a.m. and 3 p.m. during the winter, and between 8 a.m. and 10 a.m., and 2 p.m. and 4 p.m. during the summer. The recommended period for exposure to the sun is half-an-hour, three to four days a week, he said.
