Are you getting enough sleep?

When was the last time you woke up bright-eyed after a solid night’s rest?

The National Sleep Foundation came out with sleep recommendation numbers Monday, suggesting that adults should get an average of seven to nine hours of shut-eye.

The recommendations don’t vary too widely from past years’– people need less sleep as they get older. And the biggest takeaways are those that you’re probably already familiar with — that too little sleep and too much sleep can hurt a person’s health.

Here’s a breakdown of those numbers:

• Newborns, 0-3 months: 14-17 hours
• Infants, 4-11 months: 12-15 hours
• Toddlers, 1-2 years: 11-14 hours
• Preschoolers, 3-5 years: 10-13 hours
• School-age, 6-13 years: 9-11 hours
• Teenagers, 14-17 years: 8-10 hours
• Young adults, 18-25 years: 7-9 hours
• Adults, 26-64 years: 7-9 hours
• Older adults, 65 and older: 7-8 hours

If only nap time was implemented in the workforce. George Costanza was onto something.
