Light Exposure during Sleep may Increase Insulin Resistance

Chronic overnight light exposure could have long-term effects on metabolic function. According to preliminary results from a new study, nighttime light exposure during sleep may affect metabolic function. The aim of this study was to test the hypothesis that light exposure at night during sleep adversely impacts metabolic outcomes.
 
“Our preliminary findings show that a single night of light exposure during sleep acutely impacts measures of insulin resistance,” said lead author Ivy Cheung Mason, PhD, who was a postdoctoral fellow at Northwestern University Feinberg School of Medicine when this study was conducted. “Light exposure overnight during sleep has been shown to disrupt sleep, but these data indicate that it may also have the potential to influence metabolism.”

Signs of Faster Aging Process identified through Gene Research

Gene Ageing main

An international group of researchers examined expression of genes in blood samples from 15,000 people.

New research has shed light on the molecular changes that occur in our bodies as we age. In the largest study of its kind, an international group of researchers, including experts from the University of Exeter’s Medical School, examined expression of genes in blood samples from 15,000 people across the world.

They found 1,450 genes that are linked to aging, and also uncovered a link between these genes and factors such as diet, smoking and exercise. Whilst the underlying causes of human aging are largely unknown, growing old increases the risk of diseases such as cancer, heart disease, and stroke — 3 of the leading causes of death.

The research team specifically looked for changes in gen...
