In adolescence, sleep habits profoundly affect brain development, possibly shaping cognitive functions. Prioritizing healthy sleep,including limiting evening social media use,can bolster brain health and cognitive abilities.
teh Critical Role of Sleep in Adolescent Brains
Sleep is especially crucial for brain development during childhood and adolescence. A joint study by the University of Cambridge and Fudan university in Shanghai, involving over 3,200 teenagers tracked with wearable devices, revealed that late bedtimes and insufficient sleep can hinder brain growth. This can manifest as weaker brain connectivity, smaller brain volumes, and diminished cognitive performance.
Hyperconnection and It’s Consequences
Often, poor sleep habits stem from what experts call bad “sleep hygiene,”
frequently linked to excessive screen time. Many teens spend time on social media in bed, which negatively impacts both the duration and quality of their sleep.
According to the Pew Research Center, about half of teenagers recognize that social media can harm their peers’ mental health. These issues were discussed at the joint national conference of the Italian Society of Neuro Psychopharmacology (SINPF) and the Italian Society of Neuropsychiatry of Childhood and Adolescence (Sinpia) in Cagliari, entitled “Clinical Psychopharmacology in the transition age.”
The conference aimed to “stimulate the connection between specialists with different training (pharmacologists, neurologists, childhood neuropsychiatrists, psychiatrists, addiction doctors) in order to create shared knowledge necessary to improve clinical intervention in a delicate and complex phase of each person’s life, the adolescence
according to the presidents of the conference, Matteo balestrieri, Claudio Mencacci, and Elisa Fazzi.
The Link Between Sleep and Cognitive Performance
“The study has shown that teenagers who go to bed before and sleep longer are those who get better cognitive performances
explains Sara Carucci,associated professor of infantile neuropsychiatry at the university of Cagliari. She also noted that brain scans of teenagers who stayed up late showed weaker connections among key brain areas and smaller brain volumes, notably in areas crucial for memory, such as the hippocampus. These factors contribute to lower scores on cognitive tests.
addressing Hyperconnection Problems
One potential solution is to avoid using smartphones and tablets in the evening, especially for social media. Giovanni Migliase, psychiatrist Director SC mental Health Lomellina Asst of Pavia, emphasizes that disconnecting from social networks, especially in the evening
is crucial. He also noted that a recent American research study involving boys from 13 to 17 years of age has noted 48% believing that social networks have a negative effect on their peers.5, on the other hand, admits that they also negatively affect them.
Prof. Carucci adds that poor sleep hygiene and hyperconnection often coincide with other unhealthy habits, such as insufficient physical activity, poor diet, and substance use. These factors further impair neurobiological development and increase the risk of anxiety, depression, and suicidal tendencies. The more negative lifestyles are combined, the worse the consequences in late adolescence and adulthood.
