How often do you feel sleepy during the week? A day? A couple of days? The whole week? You are not alone. The National Sleep Foundation found that 44% of US adults felt sleepy 2-4 days/week and 28% felt sleepy 5-7 days/week (National Sleep Foundation Sleep in America Poll March 2020), often leading to headaches, irritability, and malaise.1 Not getting enough sleep could also have effects on memory, immune status, weight, and long-term health.
Sleep is a critical component of a person’s overall health and well-being, enabling the body to repair and restore physically and mentally, and to be fit for the upcoming day. A good night’s sleep improves concentration, performance, and productivity, and enhances the immune system. Adults typically require 7-9 hours of sleep nightly, with some individual variation. The amount of sleep needed is largely age dependent. For example, children need more sleep to help their bodies grow and develop, and older adults, aged 65 and over, require less.
The reality is a large group of American adults are not getting the sleep they need despite the expert recommendations. Humans are the only mammal that willingly delay sleep! Many people undervalue and deprioritize sleep for fitness and nutrition, work, and other interests. Other factors also impact sleep, such as diet, alcohol and caffeine consumption, use of electronic devices, exercise, or even your bedroom environment.
While it is important to get the recommended amount of sleep nightly, sleep quality – how well you sleep – is also critical to your health. Some signs that you need to improve your sleep quality include feeling groggy, taking more than 30 minutes to fall asleep after getting into bed, regularly waking up more than one time nightly or staying awake more than 20 minutes after waking up in the middle of the night.
