What are 5 interesting facts about sleep?

Sleep is a necessary aspect of our lives that often goes overlooked. We spend about a 1/3rd of our lives sleeping. Yet many of us don’t fully understand the intricacies of this vital function. It is during this restorative period that our bodies replenish and repair. This allows us to wake up refreshed and ready to tackle the day ahead. But beyond its restorative properties, sleep is rich with fascinating facts that may surprise you. In this blog post, we will explore 5 interesting facts about sleep. These facts will not only surprise you but also provide valuable insights into the importance of a good night’s rest.

interesting facts about sleep

1. Deprivation of sleep affects your brain like being drunk

Have you ever pulled an all-nighter and noticed how your thinking becomes foggy and your reactions slow down? That’s because lack of sleep affects your cognitive abilities, impairing your brain in a similar way to alcohol. Studies have shown that being awake for 24 hours straight can have the same effect on your cognitive performance as having a blood alcohol concentration of 0.10%, which is above the legal limit in many countries. Furthermore, sleep deprivation affects your memory and learning abilities. During sleep, your brain consolidates information, forming connections that enhance your memory and learning capacity. If you don’t get enough sleep, your brain’s ability to encode and retain information is compromised. This leads to difficulties in remembering and learning new things.

2. Dreams are essential for emotional regulation

Dreams have puzzled humanity for centuries. While their exact purpose remains a mystery, researchers suggest that dreams play a crucial role in emotional regulation. One theory suggests that our brain uses dreams to process and make sense of emotions experienced throughout the day.

During Rapid Eye Movement (REM) sleep, when most dreaming occurs, your brain activity increases, and your body becomes temporarily paralyzed. This state allows your brain to simulate emotional scenarios, facilitating the regulation of emotions. By analyzing emotional experiences during dreams, your brain may create connections and memories. This helps in emotional processing when you’re awake.

3. Your sleep position can impact your health

We all have our preferred sleep positions, whether it’s sleeping on our backs, stomachs, or sides. Interestingly, these positions can affect our health in various ways. Sleeping on your back is generally considered the best position for spinal alignment. It also helps prevent back and neck pain. It also minimizes the risk of developing wrinkles, as your face doesn’t press against the pillow. However, this position can worsen symptoms of sleep apnea and snoring. This is because the tongue and soft tissues in the throat obstruct the airway while sleeping on back.

Sleeping on your stomach, while comfortable for some, can put a strain on your neck and spine. It can also lead to facial wrinkles, as your face presses against the pillow throughout the night. If you’re a stomach sleeper, try using a thin pillow or no pillow at all. This will reduce the strain on your neck. Sleeping on your side, particularly on your left side, is beneficial for digestion. It also reduces the risk of acid reflux and promotes proper circulation. It is generally recommended for pregnant women, as it improves blood flow to the uterus.

4. The optimal sleep duration varies with age

While the ideal amount of sleep for adults generally falls between 7 and 9 hours per night, the optimal sleep duration varies with age. Children and teenagers require more sleep due to the demands of growth and development.

Newborn babies sleep for about 14 to 17 hours a day, gradually decreasing as they grow older. School-age children need 9 to 11 hours of sleep, while teenagers should aim for 8 to 10 hours. As we reach adulthood, the recommended sleep duration ranges between 7 to 9 hours, depending on individual needs and lifestyle factors.

It’s important to note that the quality of sleep is just as critical as the duration. Deep, restorative sleep is crucial for overall health and well-being, regardless of age.

5. Sleep deprivation is linked to weight gain and obesity

If you’re trying to maintain a healthy weight or lose a few pounds, getting enough sleep should be part of your strategy. Research has shown that sleep deprivation can contribute to weight gain and increase the risk of obesity.

When you’re sleep-deprived, your body craves high-calorie, carbohydrate-rich foods. This is because sleep deprivation disrupts the balance of hormones that regulate hunger and satiety, leading to increased appetite.

Furthermore, lack of sleep affects your body’s ability to process and metabolize glucose. This increases the risk of developing insulin resistance and diabetes. It can also impair your physical performance, making it harder to exercise and burn calories effectively.


Sleep is a vital aspect of our lives that affects our physical and mental well-being in numerous ways. From its impact on cognitive function and memory consolidation to its role in emotional regulation, sleep plays a crucial role in our overall health. The way we sleep, the duration of sleep we need, and the consequences of sleep deprivation are all factors that should be considered when aiming for optimal health. By prioritizing sleep and adopting healthy sleep habits, we can ensure that we reap the benefits of a good night’s rest and lead healthier, more fulfilling lives. So tonight, let’s turn off those screens, create a peaceful sleep environment, and give our bodies and minds the rest they deserve.
