This dangerous daily habit affects the proper development of brain in kids

Sleep is as important for growing brains as food and water, yet it’s the first thing sacrificed in our busy lives. Recent research published in Proceedings of the National Academy of Sciences in 2024 highlights the critical role sleep plays in

, particularly in young children.
The study found that sleep deprivation affects children’s developing brains’ actual growth and health in addition to making them drained. Here are some long-term effects of sleep deprivation.

The importance of sleep in synapse formation

During childhood, the brain develops quickly, and sleep serves as essential for creating and preserving synapses, or neural connections. Memory, learning, and cognition all rely on the brain’s neurones, which grow and strengthen as we sleep. According to the study, sleep deprivation affected

synapse formation

in young animals, suggesting that a similar effect could occur in children. When children lack sleep, their brains may miss out on developing these important pathways, potentially harming their ability to absorb and remember knowledge.

Sleep disruption and cognitive deficits

Researchers discovered that young animals are more sensitive to sleep deprivation than adults, resulting in memory weaknesses such as difficulties recognising new things and learning new activities. In children, these cognitive effects may manifest as academic issues or difficulties with problem solving. Chronic sleep loss could put kids at a disadvantage academically, as they struggle with attention, memory, and focus—all necessary for effective learning.

Impact on emotional regulation and behaviour

Lack of sleep has an impact on both learning and emotional control. According to the study, youngsters find it more difficult to control their emotions after a restless night’s sleep because their developing brains are less able to adjust to sleep deprivation. This could help to explain why children who don’t get enough sleep frequently show mood swings, anxiety, and irritability. Their relationships and social development may be impacted over time by more severe behavioural problems brought on by this inability to control their emotions.

Potential link to neurodevelopmental disorders

Researchers have also observed links between sleep problems and neurodevelopmental disorders, such as autism spectrum disorder (ASD) and schizophrenia. In the study, sleep-deprived juvenile animals exhibited molecular changes similar to those seen in ASD, suggesting that inadequate sleep during critical development phases could heighten susceptibility to certain neurodevelopmental risks. Though more research is needed, these findings indicate that sleep could play a role in a child’s risk for certain mental health conditions, particularly if there is already a genetic predisposition.

Building good sleep habits for long-term brain health

Since developing brains are more vulnerable to sleep disruption, parents need to prioritize their child’s sleep schedule. Healthy sleep habits, such as regular bedtimes, and a calm environment can help ensure children get the restorative sleep they need. Creating these habits early on not only supports brain health now but also lays the groundwork for a lifelong commitment to better sleep.
