A good night’s sleep is incredibly important for your health. In fact, it is just as important as eating healthy and exercising. Unfortunately, there is a lot that can interfere with natural sleep patterns. People are now sleeping less than they did in the past, and sleep quality has decreased as well.
Here are 10 reasons why good sleep is important.
- Poor sleep is linked to higher body weight
Poor sleep is strongly linked to weight gain. People with short sleep duration tend to weigh significantly more than those who get adequate sleep. In fact, short sleep duration is one of the strongest risk factors for obesity.
In one extensive review study, children and adults with short sleep duration were 89% and 55% more likely to develop obesity. The effect of sleep on weight gain is believed to be mediated by numerous factors, including hormones and motivation to exercise. If you are trying to lose weight, getting quality sleep is crucial.
- Good sleepers tend to eat fewer calories
Studies show that sleep-deprived individuals have a bigger appetite and tend to eat more calories. Sleep deprivation disrupts the daily fluctuations in appetite hormones and is believed to cause poor appetite regulation.
This includes higher levels of ghrelin, the hormone that stimulates appetite, and reduced levels of leptin, the hormone that suppresses appetite.
- Good sleep can improve concentration and productivity
Sleep is important for various aspects of brain function. This includes cognition, concentration, productivity, and performance. All of these are negatively affected by sleep deprivation.
A study on medical interns provides a good example.
Interns on a traditional schedule with extended work hours of more than 24 hours made 36% more serious medical errors than interns on a schedule that allowed more sleep
Another study found that short sleep can negatively impact some aspects of brain function to a similar degree as alcohol intoxication (9Trusted Source).
On the other hand, good sleep has been shown to improve problem-solving skills and enhance memory performance of both children and adults.
- Good sleep can maximize athletic performance
Sleep has been shown to enhance athletic performance.
In a study on basketball players, longer sleep was shown to significantly improve speed, accuracy, reaction times, and mental well-being. Less sleep duration has also been associated with poor exercise performance and functional limitation.
A study in over 2,800 Men and Women found that poor sleep was linked to slower walking, lower grip strength, and greater difficulty performing independent activities
- Poor sleepers have a greater risk of heart disease and stroke
Sleep quality and duration can have a major effect on many health risk factors. These are the factors believed to drive chronic diseases, including heart disease.
A review of 15 studies found that people who do not get enough sleep are at far greater risk of heart disease or stroke than those who sleep 7–8 hours per night
- Sleep affects glucose metabolism and type 2 diabetes risk
Experimental sleep restriction affects blood sugar and reduces insulin sensitivity.
In a study in healthy young men, restricting sleep to 4 hours per night for 6 nights in a row caused symptoms of prediabetes. These symptoms resolved after one week of increased sleep duration.
Poor sleep habits are also strongly linked to adverse effects on blood sugar in the general population. Those sleeping less than 6 hours per night have repeatedly been shown to be at an increased risk of type 2 diabetes
- Poor sleep is linked to depression
Mental health issues, such as depression, are strongly linked to poor sleep quality and sleeping disorders. It has been estimated that 90% of people with depression complain about sleep quality. Poor sleep is even associated with an increased risk of death by suicide.
Those with sleeping disorders like insomnia or obstructive sleep apnoea also report significantly higher rates of depression than those without
- Sleep improves your immune function
Even a small loss of sleep has been shown to impair immune function. One large 2-week study monitored the development of the common cold after giving people nasal drops with the cold virus. They found that those who slept less than 7 hours were almost 3 times more likely to develop a cold than those who slept 8 hours or more. So, if you often get colds, ensuring that you get at least 8 hours of sleep per night could be extremely helpful.
- Poor sleep is linked to increased inflammation
Sleep can have a major effect on inflammation in your body. In fact, sleep loss is known to activate undesirable markers of inflammation and cell damage. Poor sleep has been strongly linked to long-term inflammation of the digestive tract, in disorders known as inflammatory bowel disease
Researchers are even recommending sleep evaluation to help predict outcomes in individuals with long-term inflammatory issues.
- Sleep affects emotions and social interactions
Sleep loss reduces your ability to interact socially. Several studies confirmed this using emotional facial recognition tests. One study found that people who had not slept had a reduced ability to recognize expressions of anger and happiness.
Researchers believe that poor sleep affects your ability to recognize important social cues and process emotional information.
the bottom line is
Along with nutrition and exercise, good sleep is one of the pillars of health. You simply cannot achieve optimal health without taking care of your sleep.
Below are some easy and effective ways on how you could help improve your sleep.
-
Stick to a sleep schedule
Set aside no more than eight hours for sleep. The recommended amount of sleep for a healthy adult is at least seven hours. Most people don’t need more than eight hours in bed to achieve this goal.
Go to bed and get up at the same time every day. Try to limit the difference in your sleep schedule on weeknights and weekends to no more than one hour. Being consistent reinforces your body’s sleep-wake cycle. If you don’t fall asleep within about 20 minutes, leave your bedroom, and do something relaxing. Read or listen to soothing music. Go back to bed when you are tired. Repeat as needed.
-
Pay attention to what you eat and drink
Don’t go to bed hungry or stuffed. Avoid heavy or large meals within a couple of hours of bedtime. Your discomfort might keep you up.
Nicotine, caffeine, and alcohol deserve caution, too. The stimulating effects of nicotine and caffeine take hours to wear off and can wreak havoc on quality sleep. And even though alcohol might make you feel sleepy, it can disrupt sleep later in the night.
-
Create a restful environment
Create a room that is ideal for sleeping. Often, this means cool, dark, and quiet. Exposure to light might make it more challenging to fall asleep. Avoid prolonged use of light-emitting screens just before bedtime such as phones, tablets, TV’s etc… Consider using room-darkening shades, earplugs, a fan, or other devices to create an environment that suits your needs.
Doing calming activities before bedtime, such as taking a bath or using relaxation techniques even reading a book, might promote better sleep.
-
Include physical activity in your daily routine
Regular physical activity can promote better sleep. Avoid being active too close to bedtime. Spending time outside every day might be helpful too like long walks and light runs.
-
Manage worries
Try to resolve your worries or concerns before bedtime. Jot down what is on your mind and then set it aside for tomorrow.Stress management might help. Start with the basics, such as getting organized, setting priorities, and delegating tasks. Meditation can also ease anxiety.
Don’t take the quality of your sleep for granted. Your Health is and should be your number one.
Sleep well …. Live Healthy!!
