A new study from The Ohio State University College of Public Health found that preschoolers who are regularly tucked into bed by 8 p.m. are far less likely to become obese teenagers than young children who go to sleep later in the evening. Bedtimes after 9 p.m. appeared to double the likelihood of obesity later in life.
Preschoolers who go to bed by 8 p.m. are half as likely to become obese teenagers as those who turn in late, according to a study from The Ohio State University College of Public Health. Establishing an early bedtime routine can also have positive benefits on behavior and cognitive development.
Research reveals that king penguins can distinguish between dangerous and benign sounds while sleeping on the beach. They react with alarm to predator calls, but not to unfamiliar sounds like a dog's growl.
