Where’s your scientific report that says sunlight significantly reduces lung cancer? We shouldn’t have people making such claims on HN without providing references. She was also home having dinner with her family by 6:30pm.

  This seems key: “ Following sun exposure advice that is very restrictive in countries with low solar intensity might in fact be harmful to women's health.” Thanks for the link. Now we know with certainty that lack of sunlight wasn’t a cause.

    I think you have misinterpreted that sentence. It is saying that too little sun exposure is harmful to health in women. See also this study which found the same for men in Norway: https://www.sciencedirect.com/science/article/abs/pii/S016950020600609X https://www.sciencedirect.com/science/article/abs/pii/S01695...

      Yes, we agree. Very restrictive exposure in countries with low solar intensity “ Susan lived in Northern California. How’s the solar intensity where she lived? “ sun exposure advice that is very restrictive in countries with low solar intensity might in fact be harmful to women's health

        Oslo is about half the UV of SF, so you would need to spend half as much time in the sun for the same benefit. If you are not outside much during the day, its still a risk factor no matter where you live. This would apply to most office workers.

        “ Research on a link between vitamin D and cancer is mixed. Some studies have shown a link between low vitamin D levels in the body and a higher risk of getting cancer or dying from cancer. However, it’s not clear if taking vitamin D or having certain vitamin D levels might help prevent cancer. It’s also not clear if vitamin D can help control the growth and spread of cancer. More research is needed to know what role vitamin D does or does not play in helping to prevent or control cancer.” https://amp.cancer.org/cancer/risk-prevention/sun-and-uv/sun-safety-and-vitamin-d.html https://amp.cancer.org/cancer/risk-prevention/sun-and-uv/sun...

        Yes indeed, it is sunlight that has the most evidence. Sun also releases nitric oxide in the skin, which reduces blood pressure, and high bp is associated with increased lung cancer hazard ratio, even for nonsmokers. https://pubmed.ncbi.nlm.nih.gov/12936899/ https://pubmed.ncbi.nlm.nih.gov/12936899/ https://www.nature.com/articles/s41598-022-13399-4 https://www.nature.com/articles/s41598-022-13399-4
