The Benefits of Coffee Before Exams

Coffee has become an integral part of my daily life. It is a hot drink that is consumed by most people daily. So, it is not surprising that students also love to have a cup of coffee before exams.

Research by Nutrition Journal suggests that coffee increases student focus, as shown in a study of 500 students.

It Helps You Stay Focused On What’s Important

Caffeine blocks adenosine receptors in the brain, which makes me feel more awake. It also increases dopamine levels in my brain, making me happier. As a result, I focus better on what’s important and can stay motivated throughout the day without getting distracted by every little thing that comes my way.

It Improves Memory

Caffeine stimulates the brain cells involved with memory formation and storage, which can improve short-term memory skills like recalling numbers or words faster than usual. So, if you want to remember everything from your textbook or notes for an upcoming test, drink a cup of coffee before studying!

It Can Boost Your Energy Levels

Coffee can provide an energy boost that will help you stay focused on your work, although you may not have had time to eat appropriately during exam season. This is particularly important if you lack energy in the afternoon or early evening when most students tend to get tired and struggle to concentrate on their work if they haven’t eaten properly during the day.

Coffee May Also Reduce Anxiety Levels

This is important during stressful situations such as exams because it contains caffeine, which acts as a stimulant in your body and releases adrenaline into your bloodstream.

This hormone helps fight stress by increasing blood pressure and heart rate so your body can react quickly in stressful situations like an exam room.

The Bad Effects of Coffee on Studying

Coffee is a fantastic drink. It has been the fuel of many intellectual endeavors, and it’s no wonder why: caffeine can improve concentration and memory, as well as increase alertness.

However, coffee can sometimes be bad for studying – especially if you’re not careful about how much you drink or how often.

It Can Overload Your System

Drinking too much coffee (or any other stimulant) can overload your system and make you

  • feel jittery
  • anxious or
  • nauseous

Your academic performance could take a hit if you overload your brain with caffeine. Caffeine is also known to cause headaches when taken in high doses over long periods.

It Can Adversely Affect Sleep

Coffee reduces the quality of sleep by disrupting deep sleep cycles, which is integral to feeling refreshed in the morning before an exam or presentation.

It Can Cause Frequent Bathroom Visits

Coffee is a diuretic, meaning it makes you urinate more than usual, so drinking too much coffee while studying may cause an inconvenient trip to the bathroom during an important test or exam.
