The effect of sleep duration on somatic growth is not completely known. One study recorded growth, height, and weight, as correlated to parent-reported time in bed in 305 children over a period of nine years (age 1–10). It was found that "the variation of sleep duration among children does not seem to have an effect on growth."
As sleep time decreased over time from the 1950s to 2000s from about 8.5 hours to 6.5 hours, there has been an increase in the prevalence of obesity from about 10% to about 23%. [2] Weight gain itself may also lead to a lack of sleep as obesity can negatively affect quality of sleep, as well as increase risk of sleeping disorders such as sleep ...
By the time infants reach the age of two, their brain size has reached 90 percent of an adult-sized brain; [84] a majority of this brain growth has occurred during the period of life with the highest rate of sleep. The hours that children spend asleep influence their ability to perform on cognitive tasks.
Significant cognitive impairments, such as shorter attention spans, slower reaction times, and mistakes in patient care tasks during night shifts, were found in a study of nurses working rotating hours. Longer workdays than twelve hours intensify these impacts, increasing the risk of workplace accidents and jeopardizing patient safety.

This isn’t the first time that better sleep has been linked with a lower risk of dementia: A study published in October even found that people with sleep apnea are more likely to develop dementia.
Over time, this can cause a decline in cognitive abilities, memory, and even emotional regulation. Certain lifestyle factors can speed up an aging brain, and our genetics also play a role ...
A comparison of data collected from the Bureau of Labor Statistics' American Time Use Survey from 1965 to 1985 and 1998–2001 has been used to show that the median amount of sleep, napping, and resting done by the average adult American has changed by less than 0.7%, from a median of 482 minutes per day from 1965 through 1985 to 479 minutes ...
