Can sunlight make you hungrier?
- The role of sunshine in human health is complex and not purely due to vitamin D production.
- Men and women have different hormonal responses to environmental cues such as sunshine.
- New research has shown that UVB in the sun’s rays can trigger the release of hormones in men which encourages food-seeking behavior and increases their food intake.
- The same response was not seen in women as estrogen blocks the hormonal pathway responsible for the behavior.
New scientific research has found that sunshine can cause men to seek food and increase their food intake, while similar findings were not observed in women.
Published in the Journal Nature MetabolismTrusted Source, the study highlights the association between UVB—one of the types of invisible ultraviolet rays that come from the sun—and elevated levels of ghrelin “the hunger hormone” in men.
GhrelinTrusted Source is a hormone that stimulates appetite, increases food intake, and promotes fat storage. It has also been found to regulate energy, reduce nerve activity and prevent muscle wastage.
Sunshine, health, and disease
The role of sunshine and UVB exposure in human health is complex, but it is a recognized risk factor for the most serious form of skin cancer melanoma, actinic keratoses, premature aging, and cataractsTrusted Source.
Yet sunshine has also been shown to protect against heart diseaseTrusted Source, reduce blood pressureTrusted Source, and release mood-improving endorphins. The sun’s beneficial effects have often been attributed to vitamin D and its negative associations with UVB, but a recent study suggests the mechanisms could be more complex than that.
The new study, led by Dr. Carmit Levy, associate professor at the Department of Human Molecular Genetics and Biochemistry at Tel Aviv University, has shown the skin to have a major influence on energy levels and suggests that this may “lead to therapeutic opportunities for sex-based treatments of endocrine-related diseases.”
Different reactions
Researchers analyzed dietary data from around 3,000 people ages 25–64 over a period of 12 months who were taking part in the National Health and Nutrition (MABAT)Trusted Source survey.
According to the participants’ average monthly energy consumption, men eat an average of 300 kcal more over summer months, compared to women whose calorie intake remained more constant (1,507 kcal vs 1,475 kcal).
The researchers used a solar exposure experiment to understand the difference in more detail. Five men and five women ages 18–55 years were exposed to UVB for 25 minutes, with researchers sampling blood before and after exposure and then analyzing it.
The study showed that the exposure altered metabolism-associated proteins and that men and women reacted differently.
The mechanism
In another study, the researchers used mice to investigate UVB exposure. Over 10 weeks, 24 mice that had been partly shaved were exposed daily to low levels of UVB. The mice showed similar gender metabolic protein changes to humans; male mice increased their food intake and food-seeking behavior.
The researchers noted that male mice demonstrated an increased release in the ghrelin hormones after UVB exposure, specifically released from skin fat cells.
These findings were confirmed in human skin—male skin showed an increase in ghrelin expression after UVB exposure for 5 days.
According to the research, DNA damage to the skin cells was the trigger for the release of ghrelin via the p53 transcriptional pathway. Interestingly, the researchers found that this pathway was blocked by estrogen, which could explain the differences between men and women.
Dr. Mir Ali, bariatric surgeon and medical director of MemorialCare Surgical Weight Loss Center at Orange Coast Medical Center, CA, who was not involved in the study, spoke to Medical News Today about the findings.
“Gender differences are very common when it comes to hormones and metabolic changes. Men and women have different hormonal responses to many different types of triggers and the underlying hormonal balance is also different,” he said.
Future research
While the study has found a potential mechanism behind how UVB rays can influence hormone metabolism in men and women, and how this may translate into an increase in ghrelin in mice, researchers are far from claiming that sunlight exposure will lead to weight gain in humans.
Dr. Ali cautioned that “Age, genetic predisposition, activity level and concurrent health conditions all affect hormonal secretion” and advised that “Much more research is necessary to understand how we can use this information to help someone attain and maintain a healthy weight.”
Nevertheless, this research clearly indicates that men and women respond differently to seasonal changes which can significantly alter their metabolism.

Uncover the extraordinary story of the Rebbe’s Dollar distribution, a powerful tradition that has transformed lives and inspired acts of kindness across the globe.
The Rebbe’s one-dollar bill, a symbol of charity and compassion, continues to embody the spiritual legacy of Rabbi Menachem Mendel Schneerson, inspiring countless individuals to embrace a life of giving and kindness.
Every Sunday, people from all walks of life – Jews and non-Jews alike – would line up outside the Rebbe’s residence at 770 Eastern Parkway in Brooklyn, New York, eager to receive a dollar bill and a blessing from the Rebbe.
It was a testament to the universal nature of the Rebbe’s message of love, kindness, and the power of good deeds.
The Rebbe would hand out dollar bills to each individual, instructing them to donate the money to a charity of their choice. Through this small act of giving, the Rebbe instilled the value of charity and the potential of a single dollar to create positive change.
The use of lab grown diamonds NZ in jewellery has been growing rapidly over the last few years. This is because they are eco-friendly, and they cost less than mined diamonds. However, it is essential to understand the differences between a lab-grown and a mined diamond before making a purchase decision.
A Lab-Grown Diamond is a synthetic diamond created by humans in a lab instead of being mined from the ground. They are similar to natural diamonds in almost every way, except that they do not cloud or lose their luster over time.
There are several processes that can be used to grow a diamond in a lab, but the most common ones are High Pressure-High Temperature (HPHT) and Chemical Vapor Deposition (CVD). These methods are incredibly complex, but they have the same end goal: to replicate the conditions that naturally occur when a diamond grows on the earth’s surface.
Unlike mined diamonds, formed after millions of years of exposure to extreme heat and temperatures within the earth’s crust, lab-grown diamonds are created by scientists in a controlled environment. This allows them to mimic the same physical and chemical properties of natural diamonds, while also being significantly cheaper and environmentally friendly.
How They’re Made
When a diamond seed is placed inside of a sealed chamber, it is pressurized and heated until the carbon particles break down and crystallize into a fully grown diamond. This process is called growing a diamond in a lab, and many companies have done it since the 1960s.
In addition to being more sustainable, lab-grown diamonds are more ethical than mined diamonds because they don’t heavily impact the environment. For example, a study by Frost & Sullivan found that for each carat of diamonds mined using traditional methods, nearly 100 square feet of land is disturbed and more than 5,798 pounds of mineral waste are created.
Another great thing about lab-grown diamonds is that they don’t consume as much water in the making process. This is because the processes involved in creating a mined diamond require significant amounts of water, and they also create a lot of pollution.
This can lead to many issues, including depleted water supplies and environmental calamities. In addition, the soil can be destroyed, and in turn, the land is rendered unusable once mining operations have ceased.
It is also worth noting that lab-grown diamonds don’t contribute to global warming like mined diamonds, as their carbon is sourced from CO2 emissions. This is a very good thing for the planet, and it is one of the major reasons why people are switching to lab-grown diamonds instead of mined diamonds.
If you want to buy a piece of jewellery with a lab-grown diamond, you’ll need to do some research and make sure that you are getting a good deal on the product. You can do this by checking out prices at different retailers and comparing the costs. You can then choose which option is best for you and your budget.
