Shorter sleep and later bedtimes are linked to potentially harmful functional changes to parts of the brain important for coping with stress and controlling negative emotions, our recently published research found. And children in families with low economic resources are particularly at risk.

To better understand how socioeconomic disadvantage affects sleep health and brain development in children, we recruited 94 5- to 9-year-old children from socioeconomically diverse families living in New York. About 30% of the participating families had incomes below the U.S. poverty threshold.

We asked parents to report on their child's sleep environment, the consistency of their family routines, and their child's bedtime and wake-up time. We also had children complete a magnetic resonance imaging scan of their brains to analyze the size of a brain region called the amygdala and the strength of its connections with other regions of the brain.

We found that children in families with low economic resources were getting less sleep at night and going to sleep later compared with children in families with higher economic resources.

1. 😔poor kids get it coming and going.

2. schools need to start later. hs shd start at noon.

i had a kid w a non-24 clock. it was a nightmare. he ended up dropping out jr yr, we let him cuz he was about to break. took him a lonnnggg time to recover.
the gifted school my youngest went to (where most had a long commute) took a vote on this, and they didnt move it. 1# reason was that kids looked after sibs or had jobs. outrageous.

the schools that have done it have seen discipline problems drop, attendance go up, test scores go up.
1 way to fix it is to loop the 1st & 2nd periods. some kids r larks. they can get there at the normal time. kids who cant can take those classes at end of day. yes, it costs money. it’s worth it.
