Research suggests that COVID-19 lockdowns have a detrimental impact on the diet, sleep, and physical activity habits of children with obesity. Compared to pre-pandemic behaviors, these children consumed more junk food, watched more TV, and slept an extra half hour per day.
New studies reveal that low noradrenaline activity during sleep allows us to block sensory responses, while high noradrenaline levels may lead to hyperarousal. Researchers also found that anesthesia disrupts communication between cortical regions, leading to loss of consciousness.
A study found that sleep-wake disturbances, including insomnia and sleep-disordered breathing, are associated with a higher risk of recurrent events in stroke survivors. Assessing and improving sleep patterns could improve long-term outcomes for these patients.
A study of fruit fly sensory neurons has identified a 'thermometer' circuit that relays cold temperature information to the brain, inhibiting morning wakefulness. This finding sheds light on why humans struggle to wake up in winter and may have implications for understanding human sleep regulation.
