Answer to Question 2
Try to expose your face to the sun or be outdoors for 5 minutes in cold weather. If this person can get out for 5 minutes, 3 times a day, they will get enough exposure to the sun. If the weather is warm, try to get outside for at least 15 minutes a day. If one is going to be in the sun for an extended period of time, they should apply sunscreen with an sun protection factor (SPF) of at least 15.
