Pros And Cons Of Caffeine For Students

Students have a lot to deal with before, during, and even after school ends. Before school begins, most students are busy trying to find and secure housing, compare interest rates for student loans, and pack up all their belongings. After school, graduates have to worry about finding a job, a place to live, and paying off any debt that has accrued. 

Of course, most students will agree that nothing compares to the busy schedule of school life. Between studying, part-time jobs, and maintaining good grades, the busy schedules of students in school are staggering, to say the least. Naturally, it is pretty easy to discern that this taxing routine can take quite a toll on a student’s mental and physical health, as well as their studies.

To boost energy levels, many students choose to increase caffeine consumption. A survey supported by the Defense Medical Research and Development Program (DMRDP) has found that 92% percent of college students consume caffeine every year.

The survey also notes that, as in the general U.S. population, coffee is the main source of caffeine intake among the students surveyed. Energy drinks account for less than half of total caffeine intake.

Clearly, that has to come with benefits and adverse effects. See what the specific advantages and disadvantages are below.


  • Improves memory

When consumed moderately, caffeine can help improve your memory. Studies have shown that caffeine can enhance cognitive skills, particularly your memories, making them more resistant to forgetting. Participants of research who were given caffeine tablets were able to better remember and distinguish the images they were shown. They did not do as well on another day when they did not take any tablets.

These are important factors for students working on college assignments. They often make sure to see reviews to find professional writers to complete them on time and at affordable prices.

  • Lowers fatigue

Caffeine can also decrease fatigue. Coffee drinking, for instance, is closely related to feelings of alertness. It can help deal with the symptoms of fatigue. That said, excessive use might keep you alert for a short period of time, sapping all of your energy. This will be followed by a feeling of exhaustion and drowsiness, so take it in moderation.

  • Boosts energy levels

Caffeine can really boost your energy levels. This is important when you need to really focus on your studies or to churn out another tough workout session in the gym. It stimulates your nervous system so as to suppress tiredness while increasing energy levels. Again, the most important thing here is to limit your caffeine intake so that it does not become counterproductive.

  • Helps with focus 

It also boosts your ability to concentrate. As noted, it is a stimulant. It perks up your nervous system and your brain to release dopamine, a neurotransmitter controlling your ability to concentrate and maintain focus. It can thus help you with your planning or problem-solving challenges, but it might necessarily be credited for making you more creative.


  • Raises blood pressure

Caffeine does lead to an increase in blood pressure. This happens because your arteries get narrowed. You are likely to experience a spike in blood pressure within approximately an hour following your caffeine intake. 

The above is an important consideration in a discussion about caffeine for students and the ways in which they can be addressed. At worst, caffeine intake can lead to withdrawal headaches over time. If you have high blood pressure, you should perhaps avoid using excessive consumption. At the very least, consult your doctor to avoid long-term complications. 

  • Causes insomnia

If consumed later in the day, caffeine might affect your sleep. The later you take it, the more likely you are to suffer from insomnia or disrupted sleep patterns. To compensate for the lack of sleep, your body will be in a ‘sleep more’ during the day.

In addition, some other side effects of caffeine consumption, such as anxiety and digestive problems, might lead to insomnia too. Generally, it is considered good practice to have your last intake 5 or 6 hours before you hit the sack. 

  • Affects your teeth

You might not have thought about it, but caffeinated beverages affect your teeth too. This is especially true of coffee drinks. Over time, you start noticing yellowish stains on your teeth, which no toothpaste helps to get rid of. 

At worst, it leads to a buildup of plaque with further possible complications, such as cavities or periodontal diseases. The same is true of excessive amounts of sugar that caffeinated beverages are stuffed with.

  • Drains your wallet

Last but not least, caffeinated beverages are not cheap. A large cup of latte might set you off more than 10 bucks in a restaurant. Red bull is notoriously expensive too. Think of cutting down on your caffeinated drinks to enjoy greater health and financial benefits.

Final Thoughts

Caffeinated drinks are very popular, and they are likely to remain popular in the foreseeable future. While it is true that they can give an extra bounce in your step, moderate consumption is key to striking a healthy balance between the advantages and disadvantages they come with.
