Sunlight linked with lower Covid-19 deaths

Sunnier areas are associated with fewer deaths from Covid-19, an observational study suggests. Increased exposure to the sun’s rays – specifically UVA – could act as a simple public health intervention if further research establishes it causes a reduction in mortality rates, experts say. The study found that people living in areas with the highest […]

Fit Matters Most When Double Masking to Protect Yourself from COVID-19

A study published in JAMA Internal Medicine shows that wearing two face coverings can nearly double the effectiveness of filtering out SARS-CoV-2-sized particles, preventing them from reaching the wearer’s nose and mouth and causing COVID-19. The reason for the enhanced filtration isn’t so much adding layers of cloth, but eliminating any gaps or poor-fitting areas […]

Research identifies gender bias in estimation of patients’ pain

The three phenotypes are described in a paper published this week in the open-access journal PLOS ONE. Most patients included in the study (613 patients, or 60 percent) presented with what the researchers dubbed “phenotype […]

A new study from the University of Central Florida suggests that masks and a good ventilation system are more important than social distancing for reducing the airborne spread of COVID-19 in classrooms. The research, […]

Sugar not so nice for your child’s brain development

Children are the highest consumers of added sugar, even as high-sugar diets have been linked to health effects like obesity and heart disease and even impaired memory function. However, less is known about how high sugar consumption during childhood affects the development of the brain, specifically a region known to be critically important for learning […]

Evidence supports Covid hearing loss link

Hearing loss and other auditory problems are strongly associated with Covid-19 according to a systematic review of research evidence led by University of Manchester and NIHR Manchester Biomedical Research Centre (BRC) scientists. Professor Kevin Munro and PhD researcher Ibrahim Almufarrij found 56 studies that identified an association between COVID-19 and auditory and vestibular problems. They […]

Cardiorespiratory fitness improves grades at school

By confirming the link between children’s cardiorespiratory fitness and their school results, researchers at the UNIGE underline the importance of physical education classes at school. Recent studies indicate a link between children’s cardiorespiratory fitness and their school performance: the more athletic they are, the better their marks in the main subjects – French and mathematics.
