Both lack or excess of sleep can lead to health risks like hypertension, obesity, diabetes and depression among children and teenagers, warns a research team led by an Indian-origin scientist. The findings showed that insufficient hours of sleep could increase the risk of accidents and injuries and also lead to self-harm, suicidal thoughts or suicide attempts among teenagers. “Sleep is essential for a healthy life, and it is important to promote healthy sleep habits in early childhood,” said Shalini Paruthi from the American Academy of Sleep Medicine, Springfields, Illinois. A good sleep pattern can lead to better health outcome like improved attention, behaviour, learning, memory, emotional regulation, quality of life and mental and physical health.
