This is just a reminder to all the newbies out there who may not be aware that the window to make vitamin D naturally in the skin is fast approaching, so as many Iowa farmers say "Make Hay While the Sun Shines"-- in other words get outdoors everyday for at least 20 minutes in short sleeves or sleeveless shirts and shorts if possible. Cover your face if you want to and don't forget to take out eye contacts so the full spectrum sunlight can come through your eyes. Note: anyone with Seasonal Affective disorder (SAD) will need to make sure you do this. Do Not Look Directly into the Sun, just get a good dose of sunlight.
Per Dr. Micheal Holick, exposed skin can make about 10,000 IU's of the precursor to vitamin D in the skin (variations in skin tone) dark skin needs more time in order to make the same amount of precursor vitamin D.
For those of you afraid of sun exposure without sunscreen-- do 10 minutes and gradually increase to 20 minutes later in the day when the sun rays are not so strong.
