Teens who sleep late may find it difficult to control their emotions

Teens who are night owls and lack sleep may have problems managing their impulses and emotions.

Teens who want to stay up late and sleep in or who feel drowsy during the day may have a harder time with behaviour and reasoning than their peers who simply fail to get enough rest at night, a study suggests.

Even though the study found more than one in five adolescents get less than seven hours of sleep on school nights, the amount of sleep kids got didn’t influence what’s known as self-regulation, or the ability to manage things like memory, behaviour, emotions and impulses, the study found.
