    Exposure to sunlight prevents diseases

    KABUL (PAN): President Hamid Karzai's advisor on health said on Sunday that sunlight helps prevent certain diseases such as cancer, osteoporosis, heart problems and brain stroke.

    In an exclusive interview with Pajhwok Afghan News, Dr. Faizullah Kakar said a new research conducted by World Health Organisation experts showed that sunlight had vitamin D-3, preventing hardening of arteries, joint pains and depression.

    Based on a recent survey, a person needed 1,000 (25 micrograms) to 2,000 International Units (IU) of vitamin-D daily. The vitamin is received from sunlight, food, or capsules.

    "Sunlight is the best source of vitamin D-3. People must take a sunbath for 15 to 20 minutes between 10:00am and 2:00pm. We should not take a shower for an hour after a sunbath," Kakar added.

    He said those unable to take sunbaths should take 1000-IU capsules for a month. A person has 33 to 49 monograms of vitamin-D-3. People should test their blood to determine if their vitamin-D-3 levels are normal.

    Kakar said sunshine changes cholesterol into vitamin-D. "As life progresses, people work for eight hours under closed doors, and use transport to travel which is not good for health," the advisor said.
