Sleep for many is a way to restart their day and to get the much-needed rest they deserve after a long day’s work. What most don’t realize though is that not all types of sleep are the same and a simple nap won’t cut it if you really want to give your brain the chance to recover.

The best type of sleep for a fully recovered and rested brain and body is of course deep sleep, but what is it really and what are the benefits of deep sleep?

What is Deep Sleep?

Before we can start talking about the benefits you gain from deep sleep it is also good to understand what this stage of sleep this is. Deep sleep is also known as Stage 3 of the sleep cycle, when the body is completely detached from its surroundings.

This is the stage where the brain does most of its repairing and prepares you for the next day. People who wake up in the middle of a deep sleep are usually very groggy and disoriented, although many will fall right back asleep.

What are the Benefits of Deep Sleep?

Now that you are a little familiar with Stage 3 of the sleep cycle it’s time to learn why this stage of the sleep cycle is important.

Helps You Maintain a Healthy Heart

Deep sleep slows down the heart rate and gives the muscles a chance to repair themselves. Having a healthy sleep schedule ensures you reach Stage 3 of the sleep cycle and allows your heart to repair itself accordingly.

Lowers Blood Pressure

People who do not reach the deep sleep stage can trigger the production of adrenaline and cortisol in their bodies which are responsible for increasing blood pressure. Getting to the deep sleep stage relaxes the body and slows the heart beat which results in a lowered blood pressure.

Give the Immune System a Boost

The main purpose of sleep is to repair the cells in the body and to help it recover quickly from everyday wear and tear. When you reach the deep sleep stage the body naturally produces antibodies and immune cells that help in fighting off diseases.

Improves Brain Health, Memory, and Creativity

The main organ affected by the lack of sleep is the brain. Without proper sleep, the brain cannot produce new brain cells to replace those that have been damaged.

Getting enough sleep helps the brain recover and it also helps improve your memory and creativity. This is why people who are stressed at work need a break because it helps them rejuvenate their brain cells to allow them to work more effectively the following day.

Helps Maintain a Healthy Weight and Prevents Obesity

Those who lack sleep tend to become overweight because the brain requires more energy to function normally. This leads to unhealthy food cravings that are high in sugar and salt, a bad combination for someone who is watching their weight.

Another reason why weight gain is normal for people who lack sleep is due to the overproduction of ghrelin, the hunger promoting hormone, and the decreased production of leptin, which stimulates satiety. Without proper sleep, these hormones are not regulated which results in over-eating and weight gain.

Decreases Stress and Depression

Sleep deprivation can cause someone to regularly feel stressed and depressed. This is because the soothing effects of deep sleep are not felt by the brain and the body which triggers stress and depression in many people.

Prevents Diabetes

Although there are many factors that can cause diabetes, one proven factor is the lack of proper sleep. This is because people who do not reach the deep sleep stage tend to develop a metabolic disorder which causes diabetes.

If this is not addressed in its early stages this can lead to diabetes in later years. When you get enough sleep your body increases its insulin production which helps in lowering blood sugar, making deep sleep integral in maintaining a healthy body.


There are a lot of health benefits of deep sleep. Not only will you reap the benefits in the long run, but you will also feel refreshed after getting a good night’s rest. Relax, unwind, and get some sleep tonight. Your brain and body will thank you for it.
