Sunny Season Falls Short: Vitamin D Deficiency Persists Even in Summer, Study Finds

Newcastle University researchers analyzed 299 people and found vitamin D insufficiency remains common even in summer, especially among adults 65+ and individuals with darker skin. Factors include older skin less able to produce vitamin D, higher melanin blocking UVB, and northern latitude limits on summer sun. The findings suggest sun exposure alone may not boost vitamin D for high-risk groups and year-round supplementation is important, though guidelines vary and the study has caveats (all participants started with low levels and supplement users were excluded; funded by BetterYou).

Reddit user warns Melanotan II users: it darkens skin slowly, offers no sun protection, and carries serious health risks

A Reddit user who says he has injected Melanotan II for about 17 years warns that the peptide is not an instant UV shield and should not be exposed to sun too soon after starting. He describes a two-week loading period to see any darkening, reiterating that Melanotan II stimulates melanin but does not protect skin from UV damage. The drug remains untested and illegal to sell in many countries, with potential side effects including nausea, drowsiness, vomiting, loss of appetite, and, in severe cases, skin cancer or kidney issues. Experts caution that unregulated formulations can be dangerous, and highlight the health risks associated with long-term, unsupervised use.

Mole Check 101: ABCDE Signs That Could Signal Skin Cancer

Heat waves raise sunburn and skin cancer risk, so doctors advise using the ABCDE checklist to spot melanoma early: A for asymmetry, B for irregular borders, C for color variation, D for diameter over 6mm, and E for evolution (changes over time). If a mole looks suspicious or changes, consult a clinician promptly since early diagnosis improves outcomes. Those at higher risk—pale-skinned individuals, tanning bed users, or those with a family history—should be especially vigilant, and self-referral options may be available for cancer care.

Sunlight, Not Fear: A New Case for More Sun Exposure

Sunlight, Not Fear: A New Case for More Sun Exposure

Health writer Rowan Jacobsen argues in his new book that regular, safe sun exposure can promote longevity and mood, challenging the era of sun-avoidance and SPF-only skin protection. He points to studies suggesting sunscreen use hasn’t reduced skin cancer risk and notes concerns about certain chemicals in sun products, while vitamin D supplements offer little benefit for those with adequate sun exposure. The recommended approach is modest daily sun with sunscreen only when needed (no higher than SPF 30), avoiding burns, and seeking sun to support blood pressure and immune function; more sun is advised for darker skin and in darker seasons.

Sunshine Isn’t Enough: Vitamin D Deficiency Persists Year-Round for Some Groups

Newcastle University researchers find that vitamin D levels remain low year-round in adults 65+ and people from minoritized ethnic backgrounds in northern Britain, even during sunny months. The study, involving about 300 participants, shows summer sun does not reliably raise vitamin D for these groups, highlighting a potential public-health blind spot and the need for year-round strategies—such as routine clinician discussions and targeted supplementation—to prevent long-term deficiency.

Experts Warn Many Are Lacking Essential Vitamin

Vitamin D deficiency is common and can cause symptoms like fatigue, bone pain, and muscle weakness. It plays a crucial role in bone health, immune function, heart health, and mood regulation. The best sources are sunlight, fatty fish, and fortified foods, but supplements may be necessary, especially for those with limited sun exposure. Consulting a healthcare professional is recommended to determine appropriate intake.

Signs and Causes of Vitamin D Deficiency You Should Know

Despite living in a sunny region, many people, including Israelis, may still be vitamin D deficient due to sunscreen use, indoor lifestyles, and other factors. Vitamin D is essential for bone health, immune function, and potentially slowing aging, but its production is hindered by sun protection measures. Regular testing and advanced supplement delivery methods like liposomal technology can help maintain optimal levels, which are crucial for overall health and longevity.

Essential Vitamin D: Sun, Food, and Health Risks

Getting 10 to 30 minutes of sun exposure several times a week can help your body produce enough vitamin D, which is vital for bone, cardiovascular, immune, and muscle health. While foods and supplements can help, sunlight remains the best source, but it's important to wear sunscreen and consult a doctor before taking supplements due to potential medication interactions.

Common Skin Cancer Myths Debunked

Skin cancer is the most common cancer in the U.S., with excessive sun exposure being the primary cause, but other factors like genetics and viruses also contribute. It can develop in sun-protected areas and in people with certain risk factors. Prevention includes daily use of broad-spectrum SPF 30+ sunscreen, protective clothing, avoiding indoor tanning, and regular skin self-exams to catch early signs. Early detection and treatment are crucial, especially for melanoma, the deadliest form.

Expert Insights on Vitamin D: Supplements, Sunlight, and Deficiency Risks

Despite increased sunlight in summer, many people still need vitamin D supplements due to factors like skin pigmentation, age, and lifestyle. Experts recommend continuing supplementation based on individual needs, which can be determined through blood tests, to avoid deficiency or toxicity.
