Finding the sleep 'sweet spot' could help you live longer, study suggests

Researchers found that both insufficient and excessive sleep are linked to signs of biological aging and increased health risks. The findings indicate that maintaining this 'sweet spot' in sleep duration could contribute to a longer, healthier life.
