Sleep is a natural, recurring condition of the body and brain, characterized by reduced awareness, low sensory activity, decreased muscle activity and decreased interactions with surrounding environments during sleep. Sleep can occur for several reasons, including an adjustment to normal sleep patterns caused by illness or injury, the presence of an abnormal stressor, or the circadian rhythms of light and sleep cycles cause sleep disorders. Sleep is important for the maintenance of health. As sleep deprivation increases the risk of disease and deterioration of health, more research is being directed at understanding the health consequences of sleep loss and related sleep disorders. Understanding sleep disorders can lead to better treatment and prevention of sleep problems.
Health professionals often associate poor sleeping habits with poor health. It is possible that poor sleeping habits lead to an unhealthy outcome through a synergistic interaction of factors such as sleep deprivation, anxiety, depression, negative emotions and physical health. However, the relationship between sleep and physical health is not as clear as many assume. In fact, it may be that sleep deficiency leads to a poorer quality of life but does not lead to physical illness.
The relationship between lack of sleep and poor health is not clearly understood, but there is some evidence that lack of sleep may lead to several diseases or conditions. Sleep deficiency can often lead to higher blood pressure, increased insulin resistance (a greater risk of diabetes), higher cholesterol levels, slower wound healing, a reduction in the severity of chronic pain, depression and irritability, and a shorter life span. There is also some evidence that microsleep (that is, a rapid eye movement sleep) is beneficial for depression.
The lack of sleep associated with sleep disorders can have serious health consequences. Chronic insomnia is known to increase the risk of serious health complications, including cardiac arrhythmias, strokes, erectile dysfunction, and cancer. Microsleep may boost health through several ways. In the majority of people who are sleep deprived, their chronic insomnia is related to underlying medical problems, so sleep may not be the solution, but may worsen the underlying condition.
Sleep quality has multiple implications on health. People feel rested and more energetic after going to bed for the recommended number of hours. However, many people feel that insufficient sleep spares them from the ravages of aging. Studies have not proven any link between insufficient sleep and decreased productivity, but people feel that it’s better not to have too much than too little.
Chronic lack of sleep can also affect your health due to other lifestyle factors. Chronic smokers may feel that they are sleeping better than non-smokers (who smoke but don’t smoke), but smoking may make you more tired and less alert during the day. Lack of healthy sleep habits can lead to higher rates of obesity and hypertension. It can also increase the risk of developing heart disease, stroke, and certain cancers. Research has also shown that lack of sleep may be a cause of many psychiatric disorders including depression and anxiety.
Most people need about seven to nine hours of sleep every night, depending on your sleep needs and your stage in life. Some older people, children, and adults require slightly less than the required sleep; however, research has shown that people of all ages are able to sleep well if their sleep schedule matches their waking hours. A healthy sleep schedule is one in which your body time-weights its physiological advantages and removes the disadvantages. To get the best result, you need to have a good sleeping environment: a dark, quiet room where you will not be interrupted by loud noises or irritating pets. If you’re working at night and have to go to work early in the morning, your bedroom should also be quiet.
There are a lot of symptoms associated with lack of sleep such as stress, moodiness, trouble concentrating, memory problems, irritability, loss of energy, and increased risk of illness. Lack of sleep can be caused by insomnia, an inability to fall asleep, snoring, restless sleep deprivation. Among the most common symptoms of poor sleep quality are headache, tension, fatigue, muscle pain, irritability, loss of concentration, frequent urination, inability to remember things and frequent dreams or thoughts about the day. Poor sleep affects your health, because sleep deprivation interferes with your immune system and causes chronic diseases such as cardiovascular disease, diabetes, hypertension, and obesity. Sleep deprivation can also decrease the quality of your life and relationships, making you feel less motivated and less productive.
