Getting a good night’s sleep is important to both our physical and mental wellbeing, however it is not always as easy as it seems. It has been reported that as many as 31% of adults in the UK suffer from insomnia, two-thirds suffer from disrupted sleep and almost a quarter of adults do not manage more than 5 hours of sleep a night. The NHS recommends that adults should be getting between 6 and 9 hours of sleep per night.
Sleep is essential in the functioning of our bodies. The benefits of a good night's sleep are multifaceted. A lack of sleep can have a direct effect on both our physical and mental wellbeing. Sleep allows our body to repair itself, consolidate memories, and regulate growth and appetite. If sleep is cut short so are these processes.
A lack of sleep may result in weight gain. This is because sleep plays an important role in maintaining a healthy hormone balance that allows appetite to be regulated. Studies have shown that those getting a good night’s sleep are likely to eat fewer calories throughout the day than those who have not had a good night’s sleep. Eating more calories in a day can therefore lead to increased weight gain.
Sleep can also affect productivity and concentration. You may have felt this yourself, if you do not get a good night’s sleep you may not be able to concentrate, make decisions, or solve problems. In some cases, you may have accounted this to a lack of motivation, something that a lack of sleep can also have a negative impact on however, it is likely much more than this. Studies have shown that sleep deprivation can impair cognitive performance to the same level that the consumption of alcohol does. This can be a potentially life-threatening side effect of sleep deprivation; this is because people often drive despite a lack of sleep. These slower response times and a lack of concentration can then lead to car accidents.
The benefits of a good night’s sleep do not just stop at cognitive function and appetite regulation, sleep can also help your body to physically function more effectively. By not sleeping for between 6 and 9 hours, the time your body has to repair itself is cut short. While you are sleeping, your body repairs your muscles, helping to reduce inflammation and pain. This will allow your physical performance to be enhanced, in comparison to if you did not have a good night’s sleep. Studies show that grip strength can be affected, as well as speed and endurance.
Not only does a lack of sleep affect the way on which your body performs physically, it can actually lead to an increased risk of developing certain health conditions. Those who do not gain between 6 and 9 hours of sleep on a regular basis are at an increased risk of heart disease, strokes, and diabetes. This is because the body carries out important processes while we sleep. Sleep allows the heart and blood vessels to be repaired; if this is not done a person is at higher risk of heart disease. In addition to this, sleep helps to control insulin levels. If this is interrupted, blood sugar may be higher than normal resulting in diabetes. A lack of sleep can also cause people to become ill with less serious conditions such as colds and viruses more frequently. This is because not getting enough sleep can impair the immune system, making you more susceptible to illness.
In addition to physical health, sleep deprivation also affects our mental wellbeing; it has been linked to an increased risk of poor mental health. Prolonged periods of insomnia can lead to the development of depression and is in many cases linked to psychological stress of some kind. The Great British Sleep Survey launched in 2011 by Sleepio asked over 6000 participants questions regarding their sleep. The results showed that those who suffer from insomnia are 4x more likely to experience relationship issues. This means that they may have difficulty maintaining relationships with friends, family, and partners. This in itself is linked to low moods and eventually to depression in some cases.
In addition to this, 80% of participants who reported suffering from insomnia, also reported frequently feeling low in mood. This figure was 3x higher than those who reported sleeping well. 95% of participants who suffered disturbed sleep also reported low energy levels. Low energy levels can often cause people not to participate in exercise; an activity proven to help reduce stress and the risk of developing depression.
During the COVID-19 pandemic, sleep is especially important as many people’s routines have been affected as they have been asked to avoid social interactions and work from home. Staying in the house for prolonged periods of time and reducing social interactions can cause low mood and breed bad habits. A change in routine can influence sleeping habits and the added stress of unexpected changes, such as remote working or children being off school, can cause sleep deprivation. When working from home it can be especially hard to concentrate; as sleep has a direct correlation to productivity and concentration, it is important to ensure you are getting between 6 and 9 hours of sleep per night.
