Step outside on a sunny day. Your skin warms up. Energy rises. Mood lifts. Now imagine hiding indoors all day, slathered in sunscreen, fearing every ray. That is the modern story. The sun is the enemy. Avoid it or get cancer. We believe that is one of the biggest lies sold by skincare brands and big pharma. Data shows avoiding sun is often more dangerous than getting it. Melanoma rates are highest in cloudy places. Our ancestors were outside all day. They stayed strong. We stay inside. And we pay the price.
This post calls out the sun avoidance myth. We look at melanoma facts, why cloudy places have higher rates, how our ancestors lived under the sun without fear, what UV actually does in the body, vitamin D3’s role, and a simple way to get sun safely today. No fluff. Just data and real patterns. If you are tired of being scared of the sun, keep reading.
The Sun Avoidance Lie: How We Got Scared of the Best Thing for Us
1970s. Ozone hole scare. Skin cancer rates are rising. Dermatologists said, “Stay out of the sun.” Wear sunscreen. Cover up. That message stuck. Sunscreen sales hit $11 billion in 2023. But cancer rates kept climbing. We believe the real problem is not sun. It is the indoor lifestyle.
EPA data: Americans spend 93% of their time indoors. Teens average 7–9 hours of screen time plus school. That leaves less than 1 hour outside daily. Hunter-gatherers were outside 10+ hours a day. Their vitamin D levels averaged 46 ng/mL (Luxwolda 2012). Modern Americans? 24 ng/mL (CDC 2023). We believe low sun exposure is the hidden epidemic. Not the sun itself.
Melanoma Facts: Highest Rates in Cloudiest Places
Melanoma is the deadliest skin cancer. Everyone says the sun causes it. Data says otherwise. Melanoma rates are highest in cloudy, northern countries. UK: 16 per 100,000 (Cancer Research UK 2023). Norway: 25 per 100,000 (Nordic Cancer Registries 2022). These places have little sun. Sunny equatorial Africa: under 1 per 100,000 (Global Cancer Observatory 2022).
2014 International Journal of Cancer study: indoor workers had a 27% higher melanoma risk than outdoor workers. 2020 British Journal of Dermatology: Melanoma on the trunk (less sun-exposed) increased more than on sun-exposed sites since the 1970s. We believe this flips the story. Steady sun builds protective tan and vitamin D. Weekend burns cause damage. Office life = burn on vacation. That is the risk.
Hunter-Gatherers: Outside All Day, Every Day
Hunter-gatherers did not have offices or Netflix. They were outside from sunrise to sunset. Hadza in Tanzania walk 6 hours daily (Pontzer 2012 PLOS One). San in Botswana hunt and gather 7–9 hours (Lee 1968). Skin exposed constantly. No sunscreen. No hats 24/7. They built a gradual tan. No burns. No melanoma epidemics in ancient records.
We believe this constant exposure is what the body is built for. Their vitamin D levels stayed high. Mood stayed stable. The immune system stayed strong. We hide indoors. We burn on weekends. We wonder why we feel tired and sick.
What UV Actually Does in Your Body
UV rays are not just “cancer causers.” They trigger real processes.
- UVB makes vitamin D3 in skin (Holick 2007 NEJM)
- UVA releases nitric oxide from skin stores → lowers blood pressure for 1+ hour (Liu 2014 J Investigative Dermatology)
- UV increases serotonin and endorphins → better mood (2006 Psychopharmacology)
- UV kills bacteria on skin (2018 Scientific Reports: 90% reduction in Staphylococcus aureus)
Ancestors got this every day. We get it from screens. No wonder depression rates are up 3x since 1980 (WHO 2023).
Vitamin D3: The Sun Hormone We Are Deficient In
Vitamin D3 is a hormone made in your skin from UVB. It regulates 2000 genes. Low levels are everywhere. CDC 2023: average American teen below 20 ng/mL. Hunter-gatherers: 46 ng/mL (Luxwolda 2012).
- Low D3 doubles fracture risk (Bischoff-Ferrari 2009 JAMA)
- Low D3 raises depression risk 2x (Anglin 2013 British Journal of Psychiatry)
- Low D3 linked to weaker muscles in teens (2010 Osteoporosis International)
- High D3 associated with lower risk of 12 cancers (2021 PLOS One meta-analysis)
We believe low D3 from sun avoidance is a massive modern mistake. Ancestors got D3 free from the sun. We get it from pills or deficiency.
Sun Avoidance: The Real Danger
Sun avoidance campaigns say “slip, slop, slap.” Data says otherwise. 2016 Swedish study (Journal of Internal Medicine): The highest sun exposure group had half the death rate from all causes vs. the lowest. Cardiovascular death dropped 60%. Overall, cancer did not rise.
Outdoor workers have lower melanoma than indoor workers (2014 Int J Cancer). We believe consistent sun builds protection. Burns from intermittent exposure are the problem. Avoidance fuels deficiency. Deficiency fuels disease. The lie is killing us slowly.
How to Get Sun Safely Today
No need to bake for hours. Build exposure smartly. These are the steps many people use.
- Morning walks: 15–30 min at sunrise (low UV, sets rhythm)
- Arms and legs first: expose more skin gradually
- Midday: 10–20 min for max D3 (shade if burning)
- Test D3: Aim 40–60 ng/mL (blood test 2×/year)
- Eat D3 foods: liver, fatty fish, egg yolks
Quick Comparison: Sun Exposure vs Avoidance
| Approach | Vitamin D | Melanoma Risk | All-Cause Death |
|---|---|---|---|
| High Avoidance | Low (<20 ng/mL) | Higher in indoor workers | 2x higher (Swedish 2016) |
| Moderate Sun | 40–60 ng/mL | Lower in outdoor workers | 50% lower |
| Intermittent Burns | Varies | Higher | Not studied directly |
| Hunter-Gatherer | 46 ng/mL | Low | Baseline healthy |
What We Think
We believe the “sun is dangerous” story is one of the biggest lies in modern health. Avoiding sun creates deficiency, low mood, weak immunity, and higher overall risk. Hunter-gatherers were outside all day. They stayed strong, connected, alive. We hide indoors, slather chemicals, and wonder why we feel sick. We believe moderate sun is essential. Avoidance is the real danger. Start small. Feel the difference.

FAQ
How much sun is safe?
15–30 minutes midday for most skin types builds vitamin D without burns. Darker skin needs longer. Start slow.
Does sunscreen block vitamin D?
SPF 30 blocks 97% of UVB. Daily use lowers D3 production. We believe it is fine for long exposure, not every day indoors-to-outdoors.
Why do cloudy places have higher melanoma?
Less consistent sun means less protective tan. People burn on rare sunny days. Steady exposure builds protection.
