Benefits of sleep

Sleep is often seen as a waste of time. We spend one-third of our lives asleep, and for what? It seems like a lot of effort for something that doesn’t seem to have any real benefits. But did you know that getting enough sleep can actually improve your life in a number of ways? In this blog post, we will discuss the surprising benefits of sleep and how getting enough rest can help improve your productivity, health, and overall well-being!

What is sleep?

Sleep is a naturally recurring state of mind and body, characterized by altered consciousness, reduced responsiveness to external stimuli, and temporary paralysis of the skeletal muscles. It is believed that sleep is necessary for physical restoration, mental processing, and emotional well-being.

There are a number of surprising benefits to getting enough sleep. Some of these include:

It May help you maintain or lose weight

Short sleep — defined as sleeping fewer than 7 hours each night — has been linked to weight gain and a higher BMI in numerous studies.

Sleeping fewer than 7 hours per night increased a person’s risk of becoming obese by 41% in 2020, according to an analysis. Meanwhile, sleeping longer did not raise the risk.

The mechanism by which sleep affects weight gain is complex, and it is influenced by a variety of factors, including hormones and motivation to exercise.

Sleep deprivation, for example, activates ghrelin and inhibits leptin. Ghrelin is a hormone that makes us feel hungry while leptin makes us feel full. This may cause us to believe we are hungry when we are not, which might lead to overeating.

This is backed up by a number of research, which has shown that sleep-deprived people have a bigger appetite and consume more calories.

To make up for a lack of energy, sleep deprivation may cause you to want foods that are richer in sugar and fat since they have a greater calorie content.

To make matters worse, a lack of sleep can leave you feeling lethargic and unenthusiastic about going to the gym, walking outside, or doing whatever other physical activity you like.

Supports a healthy immune system

The immune function has been shown to be reduced as a result of lack of sleep.

According to one research, people who slept fewer than 5 hours each night were four and a half times more likely to get sick than those who slept more. Those who slept for 5–6 hours were 4.24 times more likely to get sick.

Furthermore, new research indicates that getting adequate sleep improves your immune system’s antibody responses to influenza vaccinations.

Recent study results suggest that getting enough sleep before and after receiving a COVID-19 vaccination may improve immunization effectiveness. However, further study is required to understand the relationship between adequate rest and improved immunization efficacy.

Can maximize athletic performance

Sleep has been linked to improved athletic performance.

Much research has shown that getting enough rest improves fine motor skills, reaction time, muscular power, muscular endurance, and problem-solving abilities.

Furthermore, lack of sleep may raise your risk of injury and reduce your desire to work out.

Affects emotions and social interactions

Short sleep duration is linked to an increased risk of developing type 2 diabetes and insulin resistance, which is characterized by the inability of your body to utilize insulin.

In fact, a study of over 1 million people found that a short sleep duration of fewer than 5 hours or a short sleep duration of fewer than 6 hours increased the risk of developing type 2 diabetes by 48 percent and 18%, respectively.

Sleep deprivation is considered to cause physiological modifications including reduced insulin sensitivity, inflammation, and hunger hormone changes as well as behavioral modifications such as poor decision making and greater food consumption — all of which raise diabetes risk.

May strengthen your heart

poor sleep quality

Sleep quality and duration might raise your risk of heart disease.

A meta-analysis of 19 research discovered that sleeping fewer than 7 hours each day raised the risk of dying from heart disease by 13%.

Each hour reduction in sleep was linked to a 6% higher risk of all-cause mortality and heart disease, according to one research.

Furthermore, people who sleep less have a greater chance of developing high blood pressure and suffer from obstructive sleep apnea, which is characterized by interrupted breathing during sleep.

Individuals who slept less than 5 hours each night had a 61% higher risk of developing high blood pressure, according to one study.

Excess sleep in adults — more than 9 hours — was linked to an increased risk of heart disease and high blood pressure, according to the study.

Can improve concentration and productivity

Sleep deprivation has a detrimental influence on cognitive function, attention, productivity, and performance.

A recent study of overworked doctors, for example, demonstrated that physicians with moderate, severe, and very severe sleep-related impairment were 54%, 96%, and 97% more likely to have a clinically significant medical error.

Sleep deprivation has been linked to a variety of negative health effects in children, adolescents, and young adults. In addition, getting adequate sleep may help boost academic performance in kids, teens, and young adults.

Finally, adequate sleep has been linked to enhanced memory function and problem-solving abilities in both children and adults.

Affects sugar metabolism and type 2 diabetes risk

Tiredness makes it more difficult for us to control emotional outbursts and our behaviors in front of others. Tiredness might also have an impact on our capacity to perceive humor and show compassion.

Furthermore, individuals who chronically sleep less are more inclined to avoid social gatherings and become lonely.

Sleeping less, which is known to have a negative impact on your cognitive abilities, may also be a key strategy for enhancing your relations with others and becoming more sociable.

Don’t be scared to seek help from a friend, family member, or healthcare professional if you’re dealing with loneliness or emotional outbursts. To learn more, go over this list of resources.

Poor sleep is linked to depression

Sleep has a significant impact on our central nervous system. It is particularly concerned with the stress-response mechanisms known as the sympathetic nervous system and the hypothalamic-pituitary-adrenal (HPA) axis.

Sleep deprivation, especially from interrupted sleep, has been linked to increased inflammatory signaling pathways and greater amounts of undesirable inflammation markers, such as interleukin-6 and C-reactive protein.

Chronic inflammation over time may lead to the development of a variety of chronic diseases, including obesity, heart disease, several types of cancer, Alzheimer’s disease, depression, and type 2 diabetes.

Lack of sleep can be dangerous

Not getting enough sleep is harmful to both yourself and others.

When we’re fatigued, our attentional capacity drops. In fact, being severely sleep-deprived is comparable to drinking excessive amounts of alcohol.

Unfortunately, the Centers for Disease Control and Prevention (CDC) informs that one in every 25 drivers has fallen asleep behind the wheel. Those who had slept fewer than 6 hours were most likely to fall asleep while driving.

According to 2018 research, drivers who slept or less than 4 hours had an accident risk of 15.1 times greater, respectively. According to this research, each hour of lost sleep increases your likelihood of a car accident by 16%.

Furthermore, the CDC indicates that staying awake for more than 18 hours is equivalent to having a blood alcohol level (BAC) of 0.05%. This rises to 1.00 percent after 24 hours, which is well above the legal driving limit.
