How often have you asked someone how they are doing and they respond by saying, “busy”? We live in a time when being busy is cool. Busy means making time for work, errands, family obligations, and of course binging on your favorite Netflix show. And oftentimes, what is sacrificed is your sleep and, in turn, your health. So if busy is cool, is bad health cool too? You may be wondering why sleep is good for your health. There are many ways in which sleep deprivation plays a role in your mental and physical health.
Sleep is a vital part of living. Just like eating, drinking and breathing. So why are we so quick to give up sleep when the thought of giving up food, drinks or breathing has you gasping for air?
Sleep Deprivation
To understand sleep deprivation, it will first help to understand how sleep works. There are two types of sleep—rapid eye movement (REM) and non-REM. When you dream at night, you are typically in REM sleep.
REM is characterized by rapid, low-voltage brain waves, irregular breathing, and irregular heart rate. While non-REM, also a form of a deep sleep, occurs when the heart rate, breath, and blood pressure are slow and low. During non-REM, the brain waves will be slow and high-voltage. At night, we experience 3 to 5 periods of REM sleep that occur in intervals of 1 to 2 hours apart. These periods of REM can last anywhere from 5 minutes to 1 hour.
When we talk about being sleep deprived, we are referring to you not going through enough REM and non-REM sleep cycles. This ultimately affects your ability to function at your optimal point throughout the day and is explains why sleep is good for your health-both mentally and physically.

The better you sleep at night, the better you feel. But aside from the physical effects, there are benefits to your mental and emotional well-being that justify why sleep is good for your health.
1. Brain Function
When you get a good night’s sleep, you are able to perform better at work/school. Your cognitive ability and your ability to learn/absorb knowledge significantly increases. Also, when you are well-rested, you have a stronger ability to focus and make decisions—whether strategic or creative. In turn, sleep can help to advance you in your career, education, or personal life.
2. Emotional Well-Being
We now know that a lack of sleep can affect your brain function and your capacity to make decisions. This can ultimately impact your ability to control your emotions and behaviors. Sleep deprivation has been linked to out-bursts, depression, lack of motivation, stress, anger, and other negative emotional behaviors.
3. Physical Health
Aside from feeling sluggish, sleep deprivation negatively impacts your physical health over time. Sleep is a time for your body to heal and repair itself. When you are not getting enough hours of sleep each night, your risk of developing diabetes, heart disease, high blood pressure, and obesity increases greatly.
