Sleeping while exposed to any type of light whatsoever — even dim light — is linked to an increase in the likelihood of obesity, diabetes, and hypertension (high blood pressure) in older adults, according to a new study.

The study has been conducted by the Northwestern University Feinberg School of Medicine in Chicago.

“Whether it be from one’s smartphone, leaving a TV on overnight, or light pollution in a big city, we live among an abundant number amount of artificial sources of light that are available 24 hours of a day,” said Dr Minjee Kim, a corresponding author of the study.

“It appears that even a tiny amount of light has a noticeable effect on our body’s response,” Kim told Medical News Today.

While this particular study scrutnised the negative effects on adults, Medical News Today reported that previous studies have shown that not sleeping in darkness affects all age groups.

Kim explained that in young and healthy adults, who were experimented in a sleep lab overnight, increased heartrate and blood glucose was found.

New Langya virus infects 35 people in China

A new virus, which can be transmitted to humans from animals, has infected 35 people in Shandong and Henan provinces, according to a study by scientists from China, Singapore and Australia published in the New England Journal of Medicine.

So far, there has been no evidence of human-to-human transmission.

The Henipavirus (also called Langya henipavirus or LayV) was first detected in late 2018 but was only formally identified by scientists last week, the Guardian reported.

It was discovered  thanks to an early detection system for feverish people with a recent history of exposure to animals, Bloomberg reported.

The virus was found after throat swabs were taken from the patients who were mostly farmers.

The virus is entirely novel, meaning it has not infected humans before.

But two viruses from the same family had been identified previously – the Hendra virus and Nipah virus. Both can cause severe and sometimes fatal illnesses. There are no vaccines or treatments, The Sun reported.

So far, the cases have not been fatal or very serious, so there is no need for panic, said Professor Wang Linfa from the Emerging Infectious Diseases Programme at Duke-NUS Medical School in Singapore who was involved in the study.

He added that it is still a cause for alarm as many viruses that exist in nature have unpredictable results when they infect humans.

Italy launched its vaccination campaign against monkeypox on Monday, as case numbers increased at a time when health authorities are reporting vaccine shortages worldwide, Reuters reported.

Italy has reported 545 cases of monkeypox, according to the health ministry. Its vaccination campaign started more than a month after other countries that have seen higher numbers of cases, including the United States, Britain and Spain.

The first doses will be given at the Spallanzani hospital in Rome, the hospital said in a statement.

The vaccine used will be Jynneos (MVA-BN), a smallpox vaccine made by Bavarian Nordic and approved by the European Medicines Agency for protection against monkeypox, the hospital said.

On Thursday, vaccinations will also begin in Italy’s financial capital, Milan.

Monkeypox is spread chiefly by close contact, causes pus-filled sores and flu-like symptoms, and is rarely fatal. There have now been 26,500 cases worldwide outside the countries where it usually spreads, according to a Reuters tracker.

In July, the World Health Organization declared monkeypox a “public health emergency of international concern”, its highest alert level.

The first case in Italy was recorded on May 20, 2022. There are no current plans for mass vaccinations.
