Over 40% of Americans don’t get enough vitamin D, which is essential for optimal health. The sun activates vitamin D synthesis, and without it, we’re at risk for things like depression and even death. In other words, you can consider humans to be solar-charged.
Of course, you can get too much sun. Even if you apply enough sunscreen, you can be at risk for skin and eye diseases.
That’s no bueno, so you need some shelter to hide out sometimes. A wonderful solution for your yard would be a market patio umbrella.
