All of us need either sunlight or supplements to provide us with Vitamin D, but sunscreen use and other factors can impact our levels. So how can we be sure we are getting enough?
Vitamin D can only be produced by the body when ultraviolet rays from sunlight are absorbed into the skin. Once inside the body, it promotes calcium absorption, which is important for bone density, growth, and strength. Conversely, a lack of this essential vitamin may cause your body to re-absorb calcium from your bones, which make them thin and brittle. While it’s not naturally present in many foods, Vitamin D can be taken as a supplement.
Impacts of Sunscreen on Creation
While the use of sunscreen can impact the creation of Vitamin D in the summer, sunscreen use is critical in protecting us from sunburn and the formation of melanoma and other skin cancers. The good news is a recent study showed that on a weeklong, high-sun vacation, we’re able to produce enough even with regular use of sunscreen.
Exposure to Ultraviolet Rays Varies
Geographic location, season, weather, and pollution can impact your exposure to ultraviolet rays (source). Sunlight exposure and absorption are also affected by your occupation, leisure, and exercise activities. Exposure also varies by day and even the time of day. So plan ahead when making your daily activity plans.
Supplements As An Option
Many people take Vitamin D supplements, but Mixfit’s customized nutrient delivery system provides a more comprehensive and personalized method of ensuring that you’re getting the nutrients you need each day, including Vitamin D. Mixfit’s capability to personalize this combination of vitamins and nutrients is already being developed further, taking factors including weather and pollution into account when providing the daily nutrient mix.
Wearable Technology Can Help Measure Vitamin D
While wearable technology helps us track our physical activity — such as steps taken, heart rate, and sleep cycles and estimates calories burned — future wearables will also track sunlight exposure, aiding in awareness of Vitamin D production and sun safety on an individual level.
