You should strive to get at least six hours of restful slumber each and every night. An optimal amount of sleep for most people is seven hours. Adequate sleep is essential for your health and wellbeing. An increase in the release of stress hormones (e.g., cortisol, epinephrine, norepinephrine) related to the "fight or flight" response can speed up the heart rate and raise blood pressure. This scenario, if allowed to continue over time, could take a serious toll on one's health. Lack of sleep (i.e., less than six hours per night) can have many health consequences caused by the increased release of cortisol including:
If you don't get at least five hours of sleep per night, you will be 50% more likely to gain bodyweight. Hence, getting enough sleep (i.e., 7 to 8 hours) has been attributed to maintaining or even losing body weight. If you find it difficult to get continuous, uninterrupted sleep at night, seriously consider getting in a nap during the day (recommended in the mid-afternoon when metabolic rate has slowed down somewhat). Naps can be very effective in helping you to recharge (energize) but be sure to keep those naps brief--within the range of ten minutes. A longer nap will most likely make you feel sluggish. If you feel you need to nap for longer periods of time or for several times daily, consider this an indication that you are sleep-deprived. In this case, you may need to make some changes in your lifestyle to ensure you get adequate sleep during the night.
Sleeping too much also appears to not be very healthy. Research has indicated that sleeping more than eight hours per night may increase the risk of angina and coronary artery disease.
