Getting enough sleep is essential for helping a person maintain optimal health and well-being. When it comes to their health, sleep is as vital as regular exercise and eating a balanced diet.
Modern-day living in the United States and many other countries does not always embrace the necessity for adequate sleep. Yet, it is important that people make an effort to get enough sleep regularly.
The following are some of the many benefits health professionals associate with getting a good night’s rest.
Research has linked getting enough sleep to better concentration, productivity, and cognition.
There were several studies that scientists did in the early 2000s that looked at the effects of sleep deprivation.
What the researchers concluded is that sleep has links to several brain functions, including:
A more recent 2015 study in the
The link between weight gain and obesity and short sleep patterns is not completely clear.
There have been several studies throughout the years that have linked obesity and poor sleep patterns.
However, a more recent study in the journal
This research argues that many previous studies fail to account adequately for other factors, such as:
- drinking alcohol
- living with type 2 diabetes
- level of physical activity
- education levels
- long working hours
- long sedentary time
A lack of sleep may affect a person’s desire or ability to maintain a healthful lifestyle, but it may or may not be a direct contributor to weight gain.
Similarly to gaining weight, there is evidence to suggest that getting a good night’s sleep can help a person consume fewer calories during the day.
For example, one study in the
When a person does not sleep long enough, it can interfere with their body’s ability to regulate food intake correctly.
Getting a sufficient amount of sleep can boost a person’s athletic performance.
According to the National Sleep Foundation, adequate sleep for adults is between 7 and 9 hours a night, and athletes may benefit from as many as 10 hours. Accordingly, sleep is as important to athletes as consuming enough calories and nutrients.
One of the reasons for this requirement is that the body heals during sleep. Other benefits include:
- better performance intensity
- more energy
- better coordination
- faster speed
- better mental functioning
One risk factor for heart disease is high blood pressure. According to the
Doing so can reduce the chances of sleep-related conditions such as apnea and promote better overall heart health.
Sleep has links to people’s emotional and social intelligence. Someone who does not get adequate sleep is more likely to have issues with recognizing other people’s emotions and expressions.
For example, one study in the
A study appearing in
There is a link between getting adequate sleep and reducing inflammation in the body.
For example, a study in the
The study showed that sleep deprivation can contribute to these diseases — and that these diseases, in turn, can contribute to sleep deprivation.
Sleep helps the body repair, regenerate, and recover. The immune system is no exception to this relationship. Some research shows how better sleep quality can help the body fight off infection.
However, scientists still need to do further research into the exact mechanisms of sleep in regards to its impact on the body’s immune system.
Spending more time outside can improve sleep quality.
Sleep needs vary from person to person, depending on their age. As a person ages, they typically require less sleep to function properly.
According to the
- Newborns (0–3 months): 14–17 hours
- Infants (4–12 months): 12–16 hours
- Toddler (1–2 years): 11–14 hours
- Preschool (3–5 years): 10–13 hours
- School age (6–12 years): 9–12 hours
- Teen (13–18 years): 8–10 hours
- Adult (18–60 years): 7-plus hours
- Adult (61–64 years): 7–9 hours
- Adult (65+ years): 7–8 hours
As well as the number of hours, the quality of sleep is also important. Signs of poor sleep quality include:
- Waking in the middle of the night.
- Still not feeling rested after an adequate number of hours sleep.
Some things a person can do to improve sleep quality are:
- Avoiding sleeping in when you have had enough sleep.
- Going to bed around the same time each night.
- Spending more time outside and being more active during the day.
- Reducing stress through exercise, therapy, or other means.
Sleep is a vital, often neglected, component of every person’s overall health and well-being. Sleep is important because it enables the body to repair and be fit and ready for another day.
Getting adequate rest may also help prevent excess weight gain, heart disease, and increased illness duration.
