    In general, 7 1/2 to 8 1/2 hours of sleep at night are enough for most people. If you're getting that much sleep and are still tired, however, it's probably time to evaluate the quality of your sleep. Consider these questions:

    • Is your sleep/wake schedule consistent with a set bedtime and awakening time everyday?  
    • Do you have good sleep hygiene? 
    • Do you have an undiagnosed sleep disorder that needs to be treated?  

    If you aren't getting enough quality sleep, you'll typically become tired around 4:00 p.m. Your body's daily rhythm does this naturally around 6 a.m. and 4 p.m., which (not coincidentally) is the time most car crashes occur as people fall asleep at the wheel.

    One way to check if you are getting quality sleep is to have a family member or someone you trust keep watch while you're sleeping.

    Go to bed first. After an hour or so, your friend should also go to bed, but in a place he or she can keep an eye on you and hear you. You may want to put bells on the doors to the bedroom and bathroom, so you make noise if you get up.

    What did you learn? Do you snore? Do you talk in your sleep? Do you thrash around? Do you get up in the night? How often? Even if you experience only some of these symptoms and you're fatigued during the day, call your doctor and ask for a professional sleep study.

    Nearly 10% of people in the United States experience chronic insomnia. If you don’t feel refreshed after a typical night’s sleep and are sluggish during the day, you’re probably not getting sufficient sleep, says Frisca Yan-Go, MD, a neurologist in UCLA’s Sleep Disorders Center.

    If you awake feeling refreshed and ready to meet the day each morning and you do not experience any daytime sleepiness (without the use of substances to keep you awake i.e., caffeine),  you are likely experiencing enough sleep.

    Individual requirements for sleep vary but ideally, 7-8 hours a night is recommended. Signs of not having enough sleep include daytime tiredness, poor concentration, and mood changes. Napping during the day can also be a sign that night-time sleep is insufficient. Often times, these symptoms can be masked with caffeinated drinks or eventual habituation that their symptoms are the norm. Improving sleep hygiene by optimizing night time and sleep habits can improve the quality and quantity of sleep. Frequent awakenings at night can be a sign of a more serious health problem and a consultation with your physician would be recommended.
