A good night’s sleep could reduce hyperactivity and bad behaviour among children, a Finnish study reports. It has been suggested that some children who lack sleep do not appear tired, but instead behave badly. Of the 280 examined in the Pediatrics study, those who slept for fewer than eight hours were the most hyperactive. Experts said adequate sleep could improve behaviour in healthy children and reduce symptoms of attention deficit hyperactivity disorder (ADHD).
