Video Friday: Summer vacation may be over, but the summer sun is still here! Here’s how and why you should take advantage of the sun.

In the video featured today, Dr. Christiane Northrup, MD, reminds us about why we all need to get enough sunlight. It is vital to our health. While ancient cultures used the sun to heal all kinds of illnesses and to maintain health, today we are told by many health authorities to stay out of the sun. Negative messages about the sun and skin cancer, even tanning, have scared people into staying indoors or covering up at all times when going outdoors, to the point where the body is unable to reap the benefits of sunshine and UV exposure.

Listen in to hear about the key benefits of sunshine that many people are likely lacking, and how to get the most while avoiding over exposure.

Why Everyone Needs Sunlight

Here is a quick summary of what this video discusses, along with additional information and details from GrassrootsHealth:

  • Ancient cultures used sunlight for healing. The sun was mentioned in ‘medication recipes’ and for certain medical preparations, disinfection, and photochemical reactions. Sunlight was used to control germs on skin and in the environment. In fact, scientific proof of the healing effects of the sun was first recorded by Greek physicians, starting with Hippocrates, around 460-370 BC.


  • The sun is meant to be our main source of vitamin D. Our bodies naturally produce vitamin D from the sun under the right circumstances, such as the time of year or day, amount of clothing or sunscreen we are wearing, and other conditions. Given the chance, the body produces enough vitamin D from sunshine to reach recommended levels of 40-60 ng/ml (100-150 nmol/L).




  • Avoiding sun is as detrimental to health as smoking. A study among 30,000 Swedish women by Lindqvist et al. found that “smokers in the highest sun exposure group were at a similar risk as non-smokers avoiding sun exposure, indicating avoidance of sun exposure to be a risk factor of the same magnitude as smoking.



  • Are you using sunshine to get your vitamin D? How much do you need? Everyone needs different amounts of sunshine to make enough vitamin D without burning, and may need additional vitamin D from food and supplements to reach the scientists’ recommended level of 40-60 ng/ml (100-150 nmol/L). Testing your level and retesting after starting a new supplement dose or sunshine routine is necessary to ensure levels are achieved and maintained.



  • Don’t avoid the sun… Get healthy sun exposure to benefit your health!
