THE FUNCTION OF THE SUN FOR BODY HEALTH<\/a><\/h3>
\n\n Often shunned and can be dangerous for health, actually sun exposure is not always bad. Ultraviolet (UV) rays are electromagnetic radiation that comes from the sun. UV rays can be divided into 3: \n\n - UVA rays: have the longest wavelengths, but the energy and frequency they carry are lower than other UV rays. As much as 95% of UV rays that reach the earth's surface are UVA rays \n\n - UVB rays: have short waves. As much as 5% of UV rays that reach the earth's surface are UVB rays \n\n - UVC rays: have the highest frequency and the shortest waves, so they are dangerous. However, these rays react with ozone in the atmosphere so they do not reach the earth's surface \n\n When thinking about the sun and the UV rays it produces, the first thought that comes to mind is the risks posed by UV rays. But basking in the sun at the right time for enough time can provide benefits for our health. \n\n \n\n The functions of sunlight for our health include: \n\n 1. The formation of vitamin D \n\n Vitamin D is formed when the skin is exposed to sunlight, then UVB rays will react with cholesterol in skin cells resulting in a reaction for the formation of vitamin D. This vitamin D functions in maintaining the health of our bones \n\n 2. Better Sleep Quality \n\n When a person is exposed to sunlight, the hormone melatonin production appears more quickly. Where the hormone melatonin helps regulate circadian rhythms and improves one's sleep quality. \n\n 3. More Stable Mood \n\n Sunlight that enters the eyes will stimulate the brain to produce the hormone serotonin. Serotonin hormone functions to regulate emotions so that a person feels calmer, more positive and focused. \n\n 4. Children's Eye Health \n\n Exposure to sunlight at a child's age can reduce the risk of children experiencing blurry eyes. Taking the time to do outdoor activities increases exposure to natural light which can stimulate the production of the hormone dopamine. One of these hormones is found in the eye which helps the growth of the eyeball normally \n\n \n\n How long is enough time to bask in the sun? The answer is different for everyone. It also depends on age, diet, medical history, skin color, and area of residence.In general, sunbathing before 10.00 or after 16.00 about 30 minutes enough time to get benefits and not cause other health problems, but someone can consult a doctor when is the right time for sunbathing \n<\/p><\/div><\/div><\/div>

LET’S UNDERSTAND ABOUT THE ROLE OF VITAMIN D AND CALCIUM IN ADULTS<\/a><\/h3>
In Indonesia the incidence of vitamin D and calcium deficiency in the blood The incidence of vitamin D deficiency in Indonesia is still quite high, especially among workers in buildings. Vitamin D deficiency is a condition that is quite dangerous because it can interfere with the absorption of calcium in the body so that it can cause bone fragility. This should be avoided, because fragile bones can be at risk of causing fractures so that it will interfere with a person's quality of life. \n\n \n\n The Role of Vitamin D and Calcium in the Body \n\n The role of vitamin D for the body, among others, is to help the absorption of calcium, the process of cell growth, bone formation, and can reduce the inflammatory process that occurs due to a disease. In addition to vitamin D, calcium is also one of the nutrients needed by the body. Calcium plays a major role in the formation and metabolism of bones. Without enough calcium, bones can become brittle. In addition, calcium also plays an important role in the healing process of fractures. \n\n \n\n Some Food Sources to Get Vitamin D and Calcium \n\n Vitamin D is a fat-soluble (liposoluble) vitamin. Vitamin D circulates in the blood circulation in 2 forms, namely: vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Sources of vitamin D include ultraviolet light, fish liver oil, egg yolks, and milk. Calcium is a mineral that plays a role in the growth and maintenance of bones and teeth. Calcium can be obtained from various types of food and beverages such as: sardines, salmon, green vegetables, and milk and its processed products. Another source of calcium can be obtained from calcium supplements. Calcium supplements can be given if calcium levels are below normal or calcium requirements increase due to certain conditions or diseases. \n\n Vitamin D and Calcium are essential nutrients needed by everyone, especially the elderly because of the various benefits obtained from consuming vitamin D and calcium. Consuming vitamin D and calcium is also a form of preventing fractures caused by bone loss due to old age. In addition to maintaining the body's needs for vitamin D and calcium, it is important to always exercise regularly. maintain food intake so that it is always nutritious in order to maintain health. \n<\/p><\/div><\/div><\/div>
