Even adults need 7-9 hours of sleep a night.
1. Dependence on stimulants is a losing game, as your body needs more to get the same effect. There's no medals for drinking 8 cups of coffee a day.
2. An occasional cold happens. But if it seems like you are ALWAYS sick, it's a sign your immune system is compromised and your inflammatory response is on high alert.
3. When you don't get enough shut-eye, neurotransmitters production and hormone regulation suffer. Voila! Cranky Pants
4. Highly studied and highly underrated. Sleep better - lose weight faster (or at all). There seems to be something magical about 9 hours a night.
Don't Despair. Better sleep takes practice! What would happen if you added just one more minute of sleep per night, every night for the next two months?
