Sleeping, we all do for sure, but do you have a sufficient and quality sleep? If you haven’t thought much about that, I’d say, better start taking your sleep with much seriousness before it is too late, since lack of sleep can possibly result in a myriad of inimical impacts on you. If you wonder why ‘sleeping’ is so significant, keep on reading!

Significance of a good sleep

Sleeping, in fact, is extremely crucial for a healthy lifestyle, and several researches have evidence to claim that lack of sleep or less-quality sleeping could heavily impact and completely reverse or alter the normal behavioural pattern of a person. Being exhausted, being less productive, having headaches and irritability are some of those many issues that one might face due to lack of good sleep. So, it is really important to sleep well. However, it is not all about how long you sleep, but also, the hours you go to sleep at night and get up in the morning, are equally important because human body works according to a biological clock, a pattern of metabolism, called as circadian rhythm.

It is related to the light; the metabolism starts as the body exposes to the sunlight and dies off in darkness. It tells your body when to get up, get out of bed, sleep, eat and for women – even ovulate. So, when your routine doesn’t flow with the rhythm, your body gets confused and cause many health issues as mentioned above.    

Synonymously, the time between 2.00 a.m. and 4.00 a.m. is very important for your wellbeing, as it is the time you fall into a deep sleep, allowing the body to lower the functions, rest and refresh for the next day. So, if you don’t sleep soundly during these hours, it would probably reduce your productivity next day.  

However, rather unfortunately, modern lifestyle has become very occupied and stressful, so that people don’t get enough sleep at all. Lot of kids, youth and adults spend much time staring at their mobile or computer screens, instead of having a goodnight sleep. Some people even tend to believe that they could be more productive if they stay up late and do more and more work. Yet, the truth is that you won’t have even your usual productivity and efficiency the following day since the inner organs of the body become lethargic, after functioning for a longer period of time at a stretch.

Consequences

If you don’t still believe that lack of sleep can have drastic effects on you, here’s a list of what it could do to you!

  • Memory: Studies have discovered that sleep helps the brain retain new information through ‘memory consolidation’, allowing one to perform better in studies or in an exam after an adequate sleep.
  • Weight gain: You might think burning mid night oil would reduce your fat since the body is made to function restlessly but the reality is other way around. Prolonged periods of sleep may cause weight gain by altering our metabolism and hormones levels, thereby impacting our appetite.
  • Drop in productivity: You will tend to fall asleep during the daytime and get everything confused at your workplace, college or wherever it is if your body is not given enough time to rest at night.
  • Mental impact: Inadequate sleep may result in irritability, impatience and loss of focus. Also, there is a possibility for you to be chronically fatigued if you are continuously sleep deprived.
  • Physical impact: Sleep deprivation alters our immune function, so our capability of fighting infections and illnesses, is impacted.

If you are having difficulties in sleeping:

However if you are finding it hard to sleep at night, doctors, and scientists, suggest to engage in more physical exercises in sun, to provoke your metabolism and natural bodily functions. On the other hand it would make you tired, making your body crave for a deep sleep. At the same time, it is advisable to avoid taking long naps in the evening because it could make you not feel sleepy at night. But, if you continuously find it hard to sleep, it’s better to consult a doctor. So, sleeptight everyone!
