If you’re groggy in the morning despite getting enough rest, you may have to change your sleep habits.

The National Sleep Foundation recommends:

• Gradually move your bedtime back by 15 minutes each night until you reach a desired time. Set an alarm to remind you when it’s time to go to bed.
• In the late evening, avoid bright light. That means no TV, no cell phone, tablet and other screens. Turn off bright lights, and keep the room dim to prep your body for bed.
• As soon as you wake, open the blinds to let in natural sunlight. If it’s still dark, turn on the lights.
• Avoid the urge to sleep later on weekends. If you do want to sleep later, keep it to no more than an hour.
