Adults generally need 7 or more hours of sleep a night for good health. Regularly getting less is linked with problems in mood, concentration, weight, blood sugar and heart health.
Most sleep problems improve with consistent habits. When they don't, cognitive behavioural therapy for insomnia (CBT-I) is the recommended first treatment for chronic insomnia.
