Problem of sun exposure 7.1. But it breaks the other rules for vitamins because it's produced in the human body, it's absent from all natural foods except fish and egg yolks, and even when it's obtained from foods, it must be transformed by the body before it can do any good. 6 MED/h, exposing to sunlight for 25 min with 25 per cent BSA exposure, three times a week for six weeks led to an increase of mean 25(OH)D levels of participants from 59 nmol/l at the baseline to 84 nmol/l in elderly 81. But because blood calcium is critical for neuromuscular and cardiac function, the body does not allow levels to fall.
If your baby is younger than 6 months old and still has small areas of skin (like the face) exposed, apply a tiny amount of SPF 30 sunscreen on those areas. Other Helpful Report an Error Submit.
