A new study published in the journal Sleep has found that infants who experience irregular bursts of sleep have significant growth spurts in their body length. The study suggests that longer sleep corresponds to greater growth, and that increased sleep episodes increase the probability of a growth spurt by up to 43%.
A study found that teen drivers in Virginia Beach, Va., had a 41% higher crash rate compared to Chesapeake, Va., where classes started later. This is attributed to sleep loss and daytime sleepiness caused by early school start times.

Researchers found that participants who experienced severe sleep restriction showed persistent impairments in attention and reaction times after a single night of extended sleep.
A new study has found that male infants are easier to arouse from sleep than female infants at 2-4 weeks of age, but this difference resolves by 2-3 months. The study suggests that the increased risk of sudden infant death syndrome (SIDS) in males may not be due to differences in arousability.
