Benefits of Getting Enough Sleep and Ways to Improve Sleep Habits

Just like eating nutritious foods, drinking water, and exercising regularly, getting enough quality sleep is one of the most important factors in maintaining a healthy body. While the exact reason why humans need to sleep is still unknown, sleep experts have concluded that there are many benefits to getting enough sleep on a regular basis.

In this article, Portico & Bridge will share with you 8 benefits of getting enough sleep and tips on how to improve your sleep habits. Let’s take a look together.

TOP 8 Benefits of Getting Enough Sleep

During sleep, the body carries out a number of restorative processes that affect almost every part of the body. Therefore, a good night’s sleep or lack of sleep can have both mental and physical effects on the body.

Improved mood

Sleep restores the body and improves energy levels, so waking up well-rested can have a positive impact on a person’s mood. Conversely, people who don’t get enough sleep are at higher risk of mental exhaustion. Chronic sleep deprivation can lead to anxiety, depression, and irritability. However, practicing good sleep hygiene and getting enough sleep can resolve these symptoms.

Better memory

When you are sleep deprived, you may have difficulty grasping and remembering details. This is because sleep plays an important role in both learning and memory. If you don’t get enough sleep, it’s hard to focus and take in new information. Your brain also doesn’t have enough time to store memories properly to help you recall important details in a timely manner.

Healthy Heart

Quality sleep promotes cardiovascular health. During sleep, the heart and circulatory system rest, heart rate slows, and blood pressure drops. Therefore, inadequate sleep is a risk factor for unwanted cardiovascular events. Sleep deprivation keeps blood pressure high for a long time, increasing the risk of heart disease, heart attack, and heart failure.

Regulate Blood Sugar Levels

Sleep affects the body’s relationship with the hormone insulin, which helps blood sugar, or glucose, enter the body’s cells. The cells then use glucose for energy. Getting 7 or more hours of sleep each night helps ensure that blood sugar is regulated in the body.

Adults who sleep less than 7 hours at night are at risk of developing diabetes. If you don’t get enough sleep, your body’s insulin resistance increases because cells can’t use insulin properly, leading to too much sugar in the bloodstream.

Improve Mental Function

Sleep is believed to benefit memory and cognitive thinking. The theory of brain plasticity, a leading theory of why humans sleep, suggests that sleep is necessary for the brain to develop, reorganize, restructure, and create new neural connections.

Updating these connections in the brain during sleep helps individuals learn new information and form memories. Quality sleep leads to improved focus and problem-solving skills and better decision-making. In other words, a good night’s sleep can boost productivity.

Sleep deprivation can negatively impact the ability to think clearly, form memories, learn well, and function optimally during the day. The ability to think quickly slows down after just one week of insufficient sleep. Accuracy in tasks also decreases after a week of 5 hours or less of sleep per night. Sleep-deprived individuals perform poorly in activities that require quick reactions and attention to multiple tasks, such as driving.

Sleep deprivation also affects judgment. Sleeping less than five hours at night is associated with riskier behavior. A sleep-deprived person is more likely to make poor decisions because they are only able to focus on the desired outcome and not the consequences.

Restoring the Immune System

Sleep restoration theories suggest that sleep restores and repairs the body, leaving people feeling refreshed in the morning. During sleep, the body produces growth hormones that are necessary for growth in children and adolescents. These growth hormones also repair tissues and cells in people of all ages. The body also produces cytokines during sleep, which support the immune system in fighting off infections.

Sleep deprivation can impair the body’s immune response to infections. Chronic sleep deprivation can make individuals more susceptible to common infections, such as colds, while insufficient sleep over time can lead to a higher risk of impaired immunity.

Reducing Stress

Getting enough sleep each night can help manage stress.

When people wake up refreshed, they avoid the stressors that come with being under-slept, such as poor performance, overthinking which can lead to easy decision-making mistakes, and the body being low on energy. Quality sleep can also reduce anxiety, depression, and other mental health stresses related to stress.

Physical Body Growth

Sleep is an important factor in physical recovery, and the body produces the most growth hormone during sleep. These growth hormones are necessary for tissue repair and may contribute to muscle growth. Most athletes need 8 hours of sleep per night to recover and avoid overtraining and improve their performance.

If they don’t get enough sleep, athletes are at risk of decreased performance, fatigue, and mood swings. Performing when sleep-deprived also increases the risk of injury. The risk of injury increases more as athletes’ sleep time decreases and training time increases.

Maintaining a Healthy Weight

Quality sleep, along with exercise, stress control, and healthy eating choices, is an important part of maintaining a healthy weight. During sleep, the body naturally produces more appetite suppressants, called leptin, while reducing the production of the appetite stimulant ghrelin. However, on nights of too little sleep, ghrelin production increases and leptin decreases. As a result, sleep deprivation can lead to increased feelings of hunger.

5 Ways to Improve Your Sleep Habits

To achieve better sleep and the many health benefits that come with it, let’s take a look at some ways to improve your sleep habits and lifestyle adjustments that can help improve sleep quality.

Create a consistent sleep schedule

Having a regular sleep and wake schedule helps to keep your body’s natural clock consistent.

Some adults like to take naps during the day to avoid drowsiness. Napping for about 20 minutes can help reduce fatigue without affecting your sleep schedule. Naps that are too long can reduce alertness and defeat the purpose of a nap. People who choose to nap should avoid napping too late so that they can still fall asleep at their regular bedtime.

Create a quality sleep environment

While personal preferences may vary, most people sleep best in a dark, quiet, and cool bedroom. Too much light or noise at night can make people wake up or disrupt sleep. Eye masks or blackout curtains can eliminate unwanted light, earplugs and white noise machines can reduce distracting noise. Additionally, a fan can cool the room and act as a white noise machine.

Replacing old, worn, or uncomfortable mattresses and pillows with new, supportive ones can help improve sleep quality. The best mattresses and pillows for sleep depend on each individual’s preferred sleeping position and physical needs.

Avoid caffeine, nicotine, and alcohol before bed

Caffeine is a stimulant that increases energy and alertness. When consumed in the afternoon or evening, caffeine can make it difficult to fall asleep at night. Nicotine use, found in cigarettes, in the evening is associated with more nighttime awakenings. While some people drink alcohol before bed with the intention of falling asleep faster, alcohol is associated with lighter, lower quality sleep.

Exercise during the day

Regular physical activity can help improve sleep quality. However, it is best to avoid strenuous exercise close to bedtime, as this can make it harder to fall asleep. Aim to finish your workout at least three hours before bed.

Avoid electronic devices before bed

Putting away electronic devices at least 30 minutes before bed can help you fall asleep more easily. Phones, tablets, computers, and other electronic devices with screens emit blue light, which can disrupt your body’s natural production of the sleep hormone melatonin and make it difficult to fall asleep.

Instead, sleep experts recommend developing a relaxing routine in the hour before bed. During this relaxation time, choose a relaxing activity such as reading a book or taking a warm bath.

Conclusion

While everyone’s sleep needs are different, on average, sleeping more than 9 hours per night can do more harm than good. Studies have shown that people who sleep longer have more calcium buildup in their arteries and less flexible leg arteries.

The best way to get the most health benefits is to sleep 7-8 hours per night.

Hope this information will help you find a way to improve your sleep.
