Over drinking of Coffee
Coffee is a great way to get instant energy but drinking more than the usual quantity could make you sick. Caffeine increases your stress hormones called catecholamines. In response to this, it elicits the insulin levels. Insulin increases inflammation and makes you lousy. So the instant energy that you are trying to invoke can give the adverse effect in actuality when you over consume coffee.
Sleepless nights
This is a common habit in those who do last minute studies. But sleeplessness can have its negative effect when you give your examination. Even though fear tries to keep you from falling off asleep, a tired brain cannot help you with a strong memory. So it is rather better to schedule your study time table ahead of exams and not forego sleep.
Hogging and Munching
Although you might wait to eat until you starve, eating a heavy meal is not recommended during your study time. It might not only make you full and sleepy, but also cause obesity as you will stay put in one place while studying. Obesity has its own ill effects and in total be a penalty for a bad lifestyle. So, don't stay hungry just because eating will make you feel sleepy. Eating right will not make you sleepy. Break your meals right and do not skip it. After all your brain too needs some energizing food to stay active.
