Our distant ancestors were in the sun to hunt and gather; their survival depended on it. These ancestors did not have air-conditioning or other modern comforts to draw them indoors. 

Many of us could stay inside all day where the temperature is cooler. It sure is nice to have the option, but we might choose to be out more if it were hot and stuffy inside.

Modern-day research shows that being outdoors for extended periods has many physical and mental health benefits. Sunshine can make you feel lighter, move more, sleep better, and have more energy.

Let's talk about getting healthy sun exposure this summer.

 

Benefits & Risks 

Healthy sun exposure may impact our longevity! One study found that sunshine could “reduce blood pressure, cut the risk of heart attack and stroke - and even prolong life.” The study noted that the benefits of sun exposure may outweigh the risks. This is because heart disease and strokes linked to high blood pressure cause about 80 times more deaths than those from skin cancer. 

Even more compelling is that according to Dr. Ruscio, sun exposure leads to the formation of the active form of vitamin D, which improves DNA repair and may PROTECT the skin from cancer. Other studies suggest that sun exposure demonstrates a significant REDUCTION in all causes of mortality. 

 

Guidelines for Exposure 

It is crucial to understand the nuance involved here. I do not want you reading this and thinking you can start spending all day at the pool without the proper precautions. Chris Kresser suggests the following guidelines.

• Notice how long it takes for your skin to turn pink outside without sunscreen.
• Get out in the sun 2-3 times a week for half the time it takes for your skin to turn pink
• Use shade, light clothing, and a wide-brimmed hat if you will be outside longer.
• Remember that the time of day, latitude, and season impact the sun’s intensity (tropics vs. the Midwest).
• Establish a baseline tan in the spring or early summer. 
• Use wisdom on vacation (consider the sun's intensity and if you have a baseline tan).
• Important Note: Babies under 6 months don’t have much melanin (opt for limited sun exposure in the morning and late afternoon rather than at noon).

 

Easy Ways to Get Sun

Getting sun can become a part of your daily routine; it doesn't need to take extra time or effort. 

• Eat breakfast outside on the deck.
• Have a picnic for lunch or dinner.
• Move outside in nature rather than at the gym.
• Go to the park instead of the coffee shop with friends.
• Take calls outside (you can even walk while talking).

 

What About Sunscreen

Kresser believes that most sunscreens on the market are not safe. They contain chemical ingredients like fragrances, parabens, alcohol, chemical solvents, and petroleum oils that break down when exposed to sunlight. (Babies are especially susceptible to the toxic effects of many common sunscreen ingredients, so use light clothes and shade instead.) 

 

Let me know if you would like to discuss this the next time you come in. I love talking about the lessons we can learn from our ancestors' ways of life.

P.S. My family uses a locally made natural sunscreen from “A Dirty Hoe.” It is a natural mineral-based product that does not contain the chemicals and preservatives found in most commercial sunscreens.
