3 Reasons Your Body Needs Restful Sleep

To help keep your body healthy, you know there are many things to do each day. From eating a balanced diet to getting regular exercise to drinking enough water, the list of things to do is long. 

One of the most important things you can do to stay healthy is get plenty of restful sleep. In fact, being deprived of good quality sleep can have lasting negative effects on your overall health and well-being. 

At Northwest Pulmonary and Sleep Medicine in Algonquin, Illinois, Dennis Kellar, MD, Madhu Gundavaram, MD, and our expert team know how important restful sleep is, and we’re here to help you get better sleep with our comprehensive sleep medicine services. 

Most adults need at least seven hours of restful sleep each night. If you don’t get the sleep you need, your risk for developing many diseases and medical conditions increases. 

To help you understand why it’s so important to make good sleep a priority, we’ve gathered our top three reasons why your body needs restful sleep each night.

Reason 1: Sleep is essential for brain function

Sleep plays a key role in keeping your brain functioning the way it’s designed to function. While you rest, your brain is hard at work creating new neural pathways to help you retain information and learn. 

Sleep also enhances your ability to solve problems, pay attention, make decisions, and even be creative. When you don’t get enough sleep, you may suffer from impaired judgment, difficulty concentrating, trouble learning, memory problems, and slower reaction timing. 

The National Sleep Foundation explains that most adults require 7-9 hours of sleep each night. Very young children (0-5) require substantially more sleep, usually 10-17 hours, and school-age and teenage children require 9-11 hours each night. 

Reason 2: Sleep keeps your immune system and heart healthy 

Just like your brain needs sleep to function at its best, so does your body. In fact, restful sleep is imperative for a healthy immune system and heart. While you sleep, your body performs important repairs, regenerating and recovering from the stresses of the day. 

When you don’t get enough restful sleep, your body experiences impaired immune function. Research shows that without enough sleep, you’re nearly three times more likely to develop a viral infection, such as the common cold or influenza, than those who sleep for eight or more hours each night. 

Likewise, sleep quality and duration have a big impact on your heart health. People who don’t get enough high-quality sleep regularly have a significantly greater risk of suffering from heart disease and stroke. 

Poor sleep hygiene is also linked to many other health conditions, including Type 2 diabetes, inflammation, and weight gain.

Reason 3: Lack of sleep is linked to mental health disorders

The majority of people who struggle with depression also struggle with sleep quality. In fact, the risk of developing mental health issues increases when you don’t get enough restful sleep each night. 

For example, a recent study evaluated the link between sleep and suicide and found that sleep deprivation and a lack of restful sleep played a contributing role in many cases.
