Between work, kids, busy schedules, and trying to get things done, some people just do not get enough sleep. How much sleep do you need? There's no magic number. Some people can function on 4 hours of sleep and others need at least 8 hours.
The National Sleep Foundation states that, "Each one of us has a unique sleep requirement. Our sleep need depends upon genetic and physiological factors and also varies by age, sex, and previous sleep amounts. However, a simple definition of sufficient sleep is a sleep duration that is followed by a spontaneous awakening and leaves one feeling refreshed and alert for the day."
Lack of sleep can cause health issues such as possible increases in heart rate and blood pressure, increases risk for coronary artery disease, impairs glucose tolerance, increases hunger and appetite, and increases risk of hypertension (diabetes and weight gain) just to name a few. In addition to health issues, lack of sleep can jeopardize your safety and the safety of those around you.
Harvard Medical School Division of Sleep states that lack of adequate sleep affects mood, motivation, judgment, and our perception of events. The bottom line is that lack of sleep impedes learning and memory and it can affect your health.
It's important to let your body heal, refresh, and recharge.
