How COVID-19 lockdown has altered sleep in the US and Europe

Two new studies show that relaxed school and work schedules and more time spent at home has led people to sleep more on average with less ‘social jetlag’ as indicated by a reduced shift in sleep timing and duration on work days versus free days. But, at the same time, one of the studies also finds that the pandemic has taken a toll when it comes to self-reported sleep quality. Source

Sleep, death and … the gut?

A new study finds a causal link between sleep deprivation and death. In sleep-deprived fruit flies, death is preceded by the accumulation of molecules known as reactive oxidative species in the gut. When fruit flies were given antioxidant compounds that neutralize ROS, sleep-deprived flies remained active and had normal lifespans. The findings may one day inform new approaches to counteract the harmful effects of insufficient sleep in humans. Source
