9 Reasons Why Good Sleep Is Important

A good night’s sleep is incredibly important for your health. In fact, it’s just as important as eating healthy and exercising. Unfortunately, there’s 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 9 reasons why good sleep is important.

1. Poor sleep and higher body weight are linked

Poor sleep is strongly linked to weight gain. There is a growing body of research indicating that short sleep duration coincides with obesity. One explanation might be that sleep duration affects hormones regulating hunger. Another contributing factor might be that when feeling tired, people are less active and don't exercise regularly.

BOTTOM LINE: Studies show that short sleep duration can cause weight gain in all age groups.

2. Good sleepers are less hungry

Studies show that people who sleep only 4 hours per night, compared to 10 hours per night, have an increase in hunger and appetite, especially for calorie rich foods such as junk foods that are packed with carbohydrates and fat. There are two hormones that regulate hunger called leptin (decreases appetite) and ghrelin (stimulates appetite) that can be controlled by the amount of sleep. When the body is sleep-deprived, ghrelin levels increase while leptin levels fall, leading to an increase in hunger. There is also the problem that for people who sleep less, they have more waking hours to eat.

BOTTOM LINE: Poor sleep affects hormones that control appetite as well as giving more hours to eat. Those who get adequate sleep tend to eat fewer calories overall because of the hormone control and less time allowed to eat.

3. Good sleep can improve concentration and productivity

Sleep is critical to the brain functions, which includes cognition, concentration, productivity, and performance.  Research implies that we require good sleep to support our high-level, thinking and problem solving abilities.

As you sleep, connections between brain cells are strengthened, and information is transferred from short to long-term memory. Without enough sleep, we can become more forgetful. This will mitigate your efforts of concentrating and being productive.

BOTTOM LINE: Good sleep can improve problem-solving skills and memory. Poor sleep has been shown to cause focus issues and impair vital brain functions, similar to the results of drinking or taking drugs.

4. There is a direct correlation between sleep and athletic performance

Sleep has been shown to enhance athletic performance. Research studies have shown that adequate sleep is required to maximize reaction time, focus, accuracy, stamina, endurance, and anaerobic power, as well as decrease daytime fatigue, recovery time, and the risk of injury.

BOTTOM LINE: Many aspects of athletic and physical performance can be improved with more higher quality sleep.

5. The risk of heart disease and stroke is greater for those who sleep less

"Well-run observational studies have connected poor sleep with poor cardiovascular outcomes and identified the pathways through which the damage occurs. However, we need further research to understand the impact of improving sleep on lowering this risk," says Dr. Susan Redline, Harvard Professor of Sleep Medicine.

Research suggests that those with healthier sleep habits such as not being a night owl, getting 7-8 hours of sleep per night, having no insomnia, not feeling sleepy during the day and not snoring, are at a lower risk for cardiovascular disease. For this particular research study in England, 385,292 British men were rated on a scale from 0-5, depending on how many of these healthy habits they possessed. For the "poorest sleepers" whose "sleep scores" were the bottom 2 percentile, compared to those with the highest, had a 34 percent higher risk for both coronary heart disease and stroke.

BOTTOM LINE: Sleeping less than 7–8 hours per night may be bad for your health.

6. Poor sleep is linked to depression

Usually, sleep is a restorative state; it provides a time for the body and mind to rest and recover from the bombardment of life. Poor or inadequate sleep can cause irritability and stress when the body can't recover properly, and chronic insomnia can cause depression, which affects about 4.4% of the world’s population.  As many people with sleep problems know, it can dramatically affect a person’s mood and overall quality of life.

BOTTOM LINE: Poor sleeping patterns are strongly linked to depression, particularly for those with a sleeping disorder.

7. Sleep improves your immune function

Now researchers from Germany have found that sound sleep improves immune cells known as T cells supporting the numerous existing studies which have reported the benefits of a good night's sleep. T cells play an important role in the body’s immune system. They found that in the study participants who slept, their T cells showed a stronger ability to attach to viruses than the T cells of people who were awake. The findings indicate that sleep has the potential to improve T cell functioning. 

BOTTOM LINE: Getting at least 7-8 hours of sleep can improve your immune function and help fight viruses.

8. Poor sleep is linked to increased inflammation

Inflammation is linked to the development of heart disease, stroke, diabetes and cancer—the common life-threatening diseases of our time. As research shows, poor sleep is a contributor to inflammation.

Laboratory studies have tested acute, prolonged sleep deprivation (conditions where sleep was restricted for more than 24 hours) and found this type of sleep loss increases inflammation activity in the body. They  have also studied partial sleep deprivation, which is the kind of insufficient sleep that so many people experience in their daily lives. While the study results are mixed, many studies show this form of everyday sleep loss elevates inflammation.

BOTTOM LINE: Sleep affects your body's inflammatory response. Poor sleep can have adverse affects on your body's inflammation levels.
