Resumen de Children who sleep less may age faster
A lack of sleep doesn't just turn children into a grumpy handful, it may also accelerate their cellular aging--a process that could have long-term health effects. Sarah James and Daniel Notterman at Princeton University and their team dug into a database. It included information on average sleep duration collected from 1567 9-year-old children from cities across the US. The team extracted DNA from saliva samples from the children, and examined the length of their telomeres. They found that telomeres were shorter in children who slept less.
