- Finding the sleep 'sweet spot' could help you live longer, study suggests
A new study published in Nature found that sleeping too little or too long is associated with signs of accelerated biological aging and increased mortality risk. The research of 500,000 people identified an optimal sleep duration of 6.4-7.8 hours, with both short and long sleep linked to higher biological age markers across multiple body systems.
