How Sleep Affects Overall Functioning

We’ve all been there. Waking up after a poor nights sleep and having to go through the motions of a normal day. It happens to the best of us and it can make our weeks a lot more difficult than they already are. As much as we feel the short-term effects, we often do not think much of the long-term effects of not getting enough sleep. Lack of sleep during extended periods of our life can contribute to some serious health, psychological, and physical problems. In fact, there is overwhelming evidence that lack of sleep is a great predictor of death. According to sleep neuroscientist and sleep researcher, Dr. Matthew Walker, Every disease that is killing us in the developed world, now has a causal link to insufficient sleep. This includes cancer, Alzheimer’s disease, stroke, cardiovascular disease, diabetes, depression, anxiety, and suicidality.

On a day-to-day basis, it is also known that lack of sleep impairs our cognitive abilities, such as sustaining concentration on tasks, learning new information, and making good decisions. Regarding operating a motor vehicle, if you are only getting 6 hours of sleep, you’re 33% more likely to get into a road traffic accident. That’s a higher percentage than if you were legally inebriated.

People who receive adequate sleep are working on an advantage. Sleep improves mental and physical energy, creativity, coming up with novel solutions, improves intelligence and emotional intelligence, and can have a positive impact on our mood by improving symptoms of anxiety and depression. Lastly, they call it beauty sleep for a reason! When we don’t receive enough ZZZ’s, it can take a toll on our appearance, leading to dull skin, fine lines, and bags under our eyes. It is crucial for your overall health and well-being to receive a sufficient amount of sleep. In today’s day and age, we can feel pressure to limit our sleep in order to be more productive. However, not getting enough sleep can actually make us far less productive and unhealthy in the short and long run. So start prioritizing sleep- your future self will thank you for it!
