Going to bed late and never getting enough sleep can damage brain development – ​​and poorer children are more in danger

Shorter sleep and later bedtime are related to potentially harmful Functional changes Our recently published study found that the brain cells are connected to the parts of the brain essential for managing stress and controlling negative emotions. Children from families with low financial resources are particularly in danger.

We are Neuroscientist who’re keen about reducing Socioeconomic differences in child development. To higher understand how socioeconomic drawback affects children's sleep health and brain development, we recruited 94 5- to 9-year-old children from socioeconomically diverse families in New York City. Approximately 30% of participating families had incomes below the U.S. poverty line.

We asked parents to inform us about their child's sleep environment, the consistency of their family routines, and their child's bedtime and wake-up times. We also had the youngsters undergo magnetic resonance imaging of their brains to research the dimensions of a brain region. called amygdala and the strength of its connections with other regions of the brain. The amygdala plays a crucial role in processing emotions and the quantity of negative emotions an individual experiences. Adversities experienced early in life can influence the functioning of the amygdala.

We found that children from families with low economic resources got less sleep at night and went to bed later than children from families with higher economic resources. In turn, shorter sleep and later bedtime were related to Reduction of the amygdala And weaker connections between the amygdala and other brain regions that process emotions. This connection between socioeconomic drawback, sleep duration and timing, and the dimensions and connectivity of the amygdala has been present in children as young as 5 years old.

Our results suggest that each the quantity and timing of sleep are essential for the function of brain regions involved in emotion processing.

However, there are probably Several aspects Association between socioeconomic drawback and poor sleep quality, e.g. not with the ability to afford a cushty bed, overcrowding, neighbourhood noise, excessive light and warmth.

What's next

Most sleep research has focused on teenagers who particularly in danger for sleep disordersHowever, our results suggest that the consequences of the environment on sleep patterns and habits begin much earlier.

To be best, interventions to enhance sleep may have to start before adolescence. Strengthening the economic resources of families in need may additionally be critical to promoting children's sleep health, brain development, and emotional well-being.
