Spring! The Sun is back for more than 12 hours daily! The sun crossed the equator at 0529 CDT. Vitamin D? Not so fast. This is Iowa and we are still too far north.
Your skin can make Vitamin D when exposed to strong enough sunlight. Strong enough sunlight happens when the sun is high enough in the sky that its UV rays are not blocked by the atmosphere. This happens at mid-day all year round in the tropics.
Iowa needs to wait another couple of weeks for our first moments of Vitamin D from the sun. Mid-day is around 1:10 to 1:25 pm CDT, depending on location. Southern Iowa will get enough sunlight several days before northern Iowa. Late June we will have 4-5 hours of opportunity.
Unfortunately, Vitamin D, Sunburn and Skin Cancer are often a package deal. You can encourage them all, or block them all with Sun-block.
Your safest move is to protect yourself from sunburn and skin cancer, and take your vitamin D3 tablets or gel-caps. A 25-hydroxy Vitamin D blood test will show if you have achieved the ideal range of 40-80 ng/ml.
You need to take control, but this is one area where naturally can have a significant downside.

Most cities in North-East Iowa tied or set records for the most days with Below Zero temperatures this winter. We are really ready for spring! Even yardwork picking up fallen sticks and branches is a Blue Zone experience.
Not all of the ice and snow drifts are gone yet. But the male birds are on solar time, and they are singing up a storm as they stake their claim to enough territory to sustain a family this summer.
My staff is watching the Decorah, IA, eagle-cam which shows the first chick has hatched. This is smart pair of birds. They built their nest a short flight from the Iowa Trout Hatchery. This is their seventh year of easy fishing.
Connecting with the natural world is always a Blue Zone. Spring is “green things springing from the dead earth”. Enjoy.

Yesterday was a Blue Zone Day. I had stayed overnight in Minneapolis after speaking there on Friday. Grandson RJ was waiting for Papa J first thing Saturday morning. We went to the park, where we hunted for pine cones for him to throw, and robins for him to chase on the vacant soccer fields. Then I walked, while he ran, to the playground at the other end of the park. Last year, at only 2, he could do some of the ladders and slides. Now he is king of all ladders and slides!
