There are many reasons why good sleep is important. Sleeping less or not getting enough sleep can affect your mood, health, and behavior in many ways. Some things that you do when you do not sleep well can have a serious impact on your sleep quality. Many people who lack sleep do not realize how great their mental and physical well-being is affected. The lack of sleep can negatively affect your mood, anxiety, appetite, concentration, memory, and energy levels. Many people who are sleep-deprived are often diagnosed as depressed or anxious.
Many people suffering from sleep deprivation also experience weight gain. Lack of sleep can lower your metabolism and increase your urge to eat more food to make up for the lack of energy. When you eat fewer calories, you may find that your weight gain is dramatically reduced.
Researchers have identified several possible reasons for weight gain and short sleep duration. One of these reasons is increased risk factors for obesity. People who have a short sleep duration and increased risk factors for obesity are likely to develop unhealthy eating habits that lead to weight gain. Other researchers believe that those individuals with short sleep duration and increased risk factors for obesity might also be at risk for depression, stress, and insomnia.
Sleep has been shown to enhance memory. In studies, adults with poor sleep habits have been found to perform worse than those with good sleep habits. It appears that the effects of sleep on memory are independent of age. Older adults are more likely to have problem-solving skills problems, which may impair their ability to process information. Individuals with poor sleep habits are also more likely to have difficulty learning new tasks and performing tasks that require attention to detail.
In a separate study, people who had inadequate sleep were linked with a greater risk of heart disease. The association was linked with poor sleep quality. People who had poorer sleep were linked with a greater risk of heart disease, stroke, congestive heart failure, and other cardiac problems. Poor sleep also linked people with higher levels of stress. People who are unable to get enough sleep are at greater risk of high blood pressure and related heart problems.
The study found that those individuals who have experienced short sleep periods and increased stress are also at greater risk of depression. The findings suggest that those with poor sleep deprivation and increased stress are at a greater risk of developing depression. In addition, those with poor sleep and depression are at greater risk of experiencing cognitive challenges, including difficulty processing information, thinking, planning, and solving problems.
There are numerous explanations for why sleep affects brain function. In one study, sleep was found to strongly link loneliness. In another study, sleep was strongly linked with memory loss. One study found that sleep loss is strongly linked with irritability. A third study showed that sleep loss is strongly linked with increased stress.
If you suffer from poor sleep deprivation, there are steps that you can take to improve your sleep quality and/or quantity. These include improving your diet, ensuring sufficient sleep duration, and avoiding alcohol and drugs that may be relaxing and stimulating. It is also important to ensure regular exercise. In one study, those who participated in at least three hours of aerobic exercise on a weekly basis had better brain function than those who participated in a minimum of one hour of exercise daily.
Of course, the above reasons also have their own psychological benefits. As we age, our brain cells begin to decline in plasticity. Because good sleep helps to promote plasticity, more brain cells are formed during good sleep and fewer during poor sleep. In a separate study, participants who slept for an extra half hour reported increased mental alertness and improved mental function. Finally, those who slept for at least six hours reported better behavioral outcomes than those who slept fewer hours.
Sleep has a profound effect on our immune system. Our immune system serves us well. When our immune system is hampered by inadequate sleep, it can leave us susceptible to infections. Those who lack enough sleep can also have lower energy levels and feel tired more often. Lack of sleep can also affect our mood and behavior. People who lack sleep are more prone to engage in dangerous behaviors, such as driving while intoxicated, and can also be more mentally distracted.
Overall, experts have linked insufficient sleep to a number of different health problems, including depression, anxiety, pain, weight gain, cardiovascular disease, diabetes, irritability, and memory lapses. And those who are unable to sleep for at least eight hours per night are strongly linked to a number of premature deaths. Lack of sleep can even cause our bodies to release higher levels of certain chemicals, such as cortisol, which can contribute to inflammation and cardiovascular disease. If you’re feeling sleepy, it might be time to consider how you can make sleeping more enjoyable.
