Does sunlight protect against obesity and diabetes?

Is sunlight useful for man?

Some doctors, mainly dermatologists, recommend protecting our skin from the sun’s rays to reduce the risk of skin cancer.

But other medical professionals note that exposure to the sun improves the overall condition of the human body.

The last statement is supported by the results of a new study, which show that moderate exposure to sunlight helps prevent the progression of obesity and the incurable disease diabetes.

Does exposure to the sun prevent the occurrence of cancer and diabetes?

Scientists conducted their study on mice that were fed a high-fat diet. The research team, led by Dr. Shelley Goldman, published the results of the study in the journal Diabetes.

It is common knowledge that exposure to sunlight, and more specifically ultraviolet radiation, is among the leading causes of skin cancer.

And public health organizations, such as the US Centers for Disease Control and Prevention, recommend prophylactically staying in the shade, using sunscreen and wearing protective clothing.

But could these measures be the reason why we do not take advantage of the beneficial effects of sunlight on our health?

Sun exposure is the main way to obtain vitamin D for the body, and its deficiency has been found to adversely affect health.

Recent studies have linked vitamin D deficiency to a number of neurodegenerative diseases, cancer and even premature death.

In the past year, the results of a study by Dr. Richard Weller and his colleagues from the University of Edinburgh, UK, were also published, which showed that moderate exposure to the sun is very beneficial for the heart, as this benefit outweighs the risk of skin cancer.

Dr. Goldman conducted the current study with Dr. Weller, investigating how exposure to UV rays affects weight gain and the development of diabetes in mice.

The scientists reached their final findings after feeding mice a high-fat diet to induce obesity and diabetes. The rodents are subsequently exposed to moderate ultraviolet radiation.

However, at this time no data has been published on how long the mice were exposed to UV light.

However, the scientists reported that the mice showed a significant delay in obesity and showed fewer signs of pre-diabetes in terms of insulin sensitivity and blood sugar levels.

It was later found that these positive effects were not due to vitamin D, but to a compound called nitric oxide, which is released from the skin and enters the bloodstream after exposure to the sun.

The scientists came to this conclusion because they applied a cream containing nitric oxide to the skin of one part of the mice and used vitamin D on the other.

The rodents that were smeared with the cream showed the same effects of delaying the progression of obesity and diabetes, while this was not observed in the other group.

According to Dr. Goldman, the discovery is important because it shows that along with a healthy diet and exercise, moderate exposure to sunlight will help prevent childhood obesity, which has become a serious problem in the past decade. a problem for Bulgaria as well.

However, the findings of Dr. Goldman and her team should be viewed with caution, because they were based on a study of mice, which are nocturnal animals and whose skin rarely exposed to sunlight.
