Sleep is the one of the most needed things for the proper functioning of our body and mind. Many people consider it as a luxury and believe that the pros of limiting the sleep hours overshadow the cost. However, often they overlook long-term consequences of fewer hours of sleep on their overall health. Proper sleep is required to regenerate some specific parts of our body, mainly our brain. After long hours of reduced sleep or wakefulness, many neurons starts to malfunction which visibly affect the behavior of a person.
Researches on Sleep Deprivation & Chronic Disorders
There are several studies that have revealed that sleep deprivation is potentially associated with the higher stress level that can further lead to impaired blood glucose level, increased inflammation, and higher blood pressure.
As per a recent study, it has been said that for well being and optimal health, any individual above the age of 18 years should get a sleep of minimum 7 hours every night. Sleeping for less than 7 hours is linked to higher risk of obesity, high blood pressure, diabetes, stroke, coronary heart disorder, mental stress and many more health issues. It is not only about the number of sleep hours you get, your sleeping style also affects your overall health. Know which side you should sleep for a good health.
Health Effects of Lesser Hours of Sleep
Many studies have associated obesity with insufficient sleep. For example, the one who sleeps for less than 7 hours every night on a daily basis are at much higher risk of gaining weight, whereas the person who sleeps for 7 to 8 hours every night had lower body fat. As per the other study on babies or infants who sleep for short hours are more likely of developing obesity later in their childhood as compared to the babies who sleeps for the recommended time period.
2. Hypertension & Cardiovascular Diseases
According to a study, it has been found that less than 7 hours of sleep every night are associated with the higher risk of coronary artery calcification, interpreter of myocardial infarction or heart attack in future which can even lead to death in some conditions. There is evidence that also display a connection between fewer sleep hours and a higher risk of cardiovascular disorder that includes stroke, hypertension, irregular heartbeat and coronary heart disorder.
Researchers have revealed that individuals who reported sleeping for less than 7 hours on a daily basis are at much higher risk of developing type 2 diabetes. But there is a good news for diabetic people, it has been found that more than 7 hours of sleep can possibly influence the blood sugar control and minimize the effects of type 2 Diabetes.
4. Immune Function
An interaction between immune system and sleep has been properly documented. Lesser hours of sleep raises the levels of several inflammatory mediators as well as infection, which in turn concern the patterns and amount of sleep. As researchers are just starting to understand these relations, an early report says that lesser hours of sleep may hamper the ability to fight or resist infection.
5. Common Cold
Individuals who sleep for less than 7 hours every night are at three times higher risk of developing cold symptoms as compared to the individuals who get their 7 hours of sleep on a regular basis when exposed to cold and flu causing rhinovirus.
6. Brain Function
Several studies have reported that sleep deprivation may also cause malfunctioning of neurons, ultimately affecting the behavior of the person. Specific levels of sleep are required for regeneration of brain or neuron within the cerebral cortex as other levels of sleep are needed for forming new synaptic connections and new memories.
It is not surprising that such potential adverse health issues can lead to some higher health care expenses and low productivity. More significantly, insufficient sleep or sleep depreciation can eventually affect your life expectancy and well-being in daily life. A study of various data from several pieces of research suggests that less than 7 hours of sleep may raise mortality risk by around 15%.
