Examinations are an evaluation of what you have learnt, understood and how well you can put it into words by manifesting your ideas properly. Though it is quite true that stress, restlessness, confusion become a part of your exam phase, with worries about marks, time management as well as peer pressure.
Eight hours of sleep are crucial and mandatory for a human body, in order to ensure that it functions well and operates on day to day tasks efficiently. During exams, when your mind is already stressed out, your sleeping pattern for every day becomes all the more crucial and needs to be well maintained.
Unhealthy sleep patterns mean weaker brain
Panic during exam time is pretty obvious, but many students mistake it grossly and think it is all right to spend nights before and during exams studying, learning those chunks of texts and reading more than what their brains can take. However, they need to understand that this act is more of a bad step, which does more harm than good.
With such rigorous study sessions and staying awake at night, your brain loses the tenacity to concentrate and focus on topics properly. You also in a way force your brain to indulge into activities, when all it needs is adequate rest to keep it functions smooth. This in return affects your mood, your learning and hence, your academic performance as well.
Higher stress levels
Inadequate sleep, unhealthy and light sleeping patterns can cause a number of health issues in your body. For the starters, sleep deprivation increases the secretion of cortisol—which is the stress hormone in our body, and as you know stress is the root cause of a number of health hiccups, be it headache, nausea, or something as chronic as diabetes.
Therefore, it is wise as well as healthy to take proper breaks between study hours and give your body and mind the right amount of rest they deserve. Only then can you concentrate well on your subjects and your brain will be rejuvenated after a long sound sleep, to focus on topics better.
