Sleep patterns around the world have been disrupted as screen time increases and sleep routines change with COVID-19 self-isolation requirements, reports Science Daily.
Negative mood is not unusual in adolescence, but lack of sleep can affect mental health, causing anhedonia (or loss of pleasure), anxiety, anger and significantly increasing the risk of depression, a global study of more than 350,000 teens shows.
The results just published in Sleep Medicine Reviews connects less sleep with a 55% increased chance of mood deficits and double the risk of reduced positive mood.
From Asia, to Australia, New Zealand, Europe and North America, sleep clearly was a modifiable risk factor that can improve or depress mood in adolescents, says Flinders University sleep researcher Dr Michelle Short.
