Are you Getting Enough Sleep?
Sleep is an altered state of consciousness in which we have limited interactions with our environment and are relatively quiet and still (depending on the stage of sleep). In contrast to our quiet physical state, the brain is very active during sleep and performs many important functions. Sleep is essential to all processes in the body, influencing our physical and mental functioning the next day, our ability to fight disease and build immunity, our metabolism, and our risk of chronic disease. Sleep is truly interdisciplinary because it affects all aspects of health.

How to Know If You’re Getting Enough Sleep
To find out if you’re getting enough sleep at night, ask yourself:
Do you feel healthy and satisfied with your current sleep schedule?
Do you feel like you’re getting enough sleep to be productive?
Do you ever feel sleepy during the day?
Do you rely on caffeine to get through the day?
Is your sleep schedule consistent enough, even on the weekends?
How to Get the Sleep You Need?
Healthy habits can help you sleep better and longer.
Give yourself time to sleep. A busy schedule can make it difficult to get a good night’s sleep.
Keep a sleep schedule. Go to bed and wake up at the same time every day, even on the weekends.
Create a sleep sanctuary. Keep your bedroom dark, quiet, and at a comfortable temperature. Use it only for sleeping, sex, and quiet activities like reading. Don’t bring electronic screens like TVs or cell phones.
Establish a bedtime routine. Avoid bright lights, heavy meals, caffeine, and alcohol before bed. Try things that help you relax, like a warm bath.
Exercise. Exercise for about 30 minutes a day, at least 5 hours before bed.
Take a nap if needed. Try to stay within 30 minutes so you don’t wake up groggy or disrupt your sleep schedule.
Don’t force it. If you find yourself awake in bed, get up and do something quiet, like reading, until you feel sleepy. Journaling can help quiet nagging thoughts.
Talk to your doctor. A medical condition could be causing your sleep problems.
