Are You Getting Enough? Eye-opening Science Behind Sleep Deprivation and Health Problems
Are you familiar with waking up felling sluggish, groggy and irritated after pulling an all-nighter, staying up till wee hours, or finishing a night shift?
Unfortunately, apart from feeling exhausted and lethargic, improper sleep does more harm to our health than we assume. We are not only paying fines for sleep deprivation in terms of lack of focus and bad mood; it has greater consequences for our long-term health.
The Vicious Effects of Sleep Deprivation
Despite rising awareness about the importance of proper sleep at night, health disorders associated with lack of adequate sleep are on continuous rise. It is estimated that approximately 1/3rd of human population suffers from health hazarding effects associated with poor sleep, working on computer and stress.
Alone in the US, approximately 50-70 million people are suffering from chronic health problems linked with sleep and wakefulness. Diabetes, heart diseases, obesity, and shortened life expectancy are the most common health disorders linked with poor sleep at night.
Research studies conducted on a group of volunteers state concluded that people getting inadequate sleep are at higher risk of falling victim to chronic diseases such as impaired control of blood glucose, increased inflammation, increase blood pressure, obesity, and diabetes. According to these epidemiological research studies, long term sleep deprivation is also linked with the development of health problem in people who are initially healthy.
Why Sleep Matters?
Usually, while we are sleeping, our body goes through a healing process; it provides a much needed energy boost to our body in order to effectively carry out hundreds of routine functions.
In order to function properly and sustain healthy energy level throughout the a day, a person needs good sound sleeping of 8 hours at night. Sometimes, our day starts with sluggishness and fighting for energy; usually, it happens due to inadequate sleep that prevents our body from getting sufficient relaxation.
Critical mood disorders including depression, mental distress, stress and anxiety are linked with chronic sleep deprivation. Adequate sleep keeps us focused at work by improving mental clarity and reducing stress level. As per a study, mental exhaustion, sadness and depression are correlated with people getting less than 4 ½ hours of sleep per night.
Research studies point out to a strong connection between development of diabetes and getting less than 5 hours of sleep. It increases the risk of developing type 2 diabetes by adversely affecting the way our body utilises glucose.
Immune Boost & Sex Drive
Adequate sleep improves our body’s immune strength and saves us from health problems associated with a weakened immune state. Lower libido is common among men and women not getting enough sleep at night. Sleep apnoea in men is associated with lower libido due to lower testosterone levels.
As per research studies, if a person is suffering from hypertension, even one night of sleep deprivation leads to increased blood pressure the following day. Poor sleeping pattern is well known to be associated with stroke, increases blood pressure, and the development of many cardiovascular diseases including coronary heart disease. Adequate sleep improves our cardiovascular health and helps in reducing high blood pressure.
Healthy Weight Loss
Sleep promotes natural weight loss. In truth, sleep deprivation means putting on more and more weight. If you are sleeping less than 7 hours, it increases your chances of gaining more weight.
Increased Life Expectancy
It is not surprising that sleep deprivation is associated with lower life expectancy. Epidemiological studies narrate that sleeping 5 hours or less at night increases mortality risk by 15 percent.
So what’s you are going to pick? Heart disease, obesity, diabetes, shortened life, or a soothing, relaxed sleep at night?
