Preparing for JAMB 2025 takes a lot of effort, and for many students, it means spending long hours studying. While this is necessary to cover all the subjects and topics, one common challenge is feeling tired and losing focus while reading.

If you often find yourself struggling to stay awake, feeling mentally drained, or unable to concentrate for long, then your study method may need some changes. The truth is, studying for long hours does not guarantee success if your brain is not working at full capacity.

In this article, we will look at why you feel tired while studying, how to stay energized, and what you can do to improve your study sessions. If you don’t have a proper study schedule yet, check out Proven Study Timetable for JAMB 2025 Candidates to organize your reading time better.

Why You Feel Tired While Studying

Many students believe that feeling sleepy or tired while studying means they are lazy or not serious enough. But that is not always true. Your brain is like a machine, and if you do not take care of it properly, it will slow down or stop working well. Here are some reasons why this happens:

1. Not Getting Enough Sleep

If you are not sleeping well at night, your brain will not have enough time to rest and recover. This makes you feel slow, tired, and less focused when studying during the day.

Some students think they can study late at night and still wake up early to continue reading, but this only makes them more tired in the long run. If you are struggling with late-night study, read Why Studying at Night for JAMB 2025 May Not Work for You to see if you need to change your routine.

2. Sitting for Too Long Without Breaks

Studying for too many hours without a break can make your brain feel overloaded. When you keep reading without stopping, your concentration reduces, and you start feeling tired, no matter how interesting the topic is.

Your brain works better when you take short breaks between study sessions. This helps you refresh your mind and come back stronger.

3. Poor Diet and Not Drinking Enough Water

Your brain needs good food and enough water to stay active. If you eat junk food, skip meals, or don’t drink enough water, you will feel weak and sleepy when reading.

Certain foods help you stay alert and focused, while others make you feel tired faster. Eating the right food can make a big difference in how long you can study without feeling exhausted.

4. Using the Wrong Study Method

If your study method is too boring, your brain will naturally lose interest, and you will feel sleepy. For example, if you just read your notes over and over again without practicing questions, you may get tired quickly.

Using active study methods can help you stay engaged and remember things better. If you don’t know how to improve your study style, check out JAMB 2025: Proven Study Tips to Score 300+ in One Sitting.

How to Stay Energized While Studying for Long Hours

If you want to study longer without feeling tired, you need to follow smart strategies that keep your brain fresh and active. Here’s what you can do:

1. Sleep Well at Night

The most important thing you can do to stay active during the day is to get enough sleep at night. Your brain needs rest to work properly. Aim for at least 6 to 8 hours of sleep every night so you can wake up refreshed and ready to study.

2. Have a Study Plan

Instead of studying randomly, organize your time properly. Studying for long hours without a plan can make you feel lost and tired. A good timetable helps you focus on one subject at a time and balance study and rest.

3. Eat Brain-Boosting Foods

What you eat affects how you study. Avoid sugary foods because they give quick energy but make you feel tired after some time. Instead, eat foods that keep your energy level steady, such as:

• Fruits like bananas, oranges, and apples
• Nuts (groundnuts, cashews, almonds)
• Whole grains like oats, brown rice, and wheat bread
• Protein-rich foods like eggs, beans, and fish

Eating well can help you stay awake and focused for a long time.

4. Drink Plenty of Water

Dehydration can make you feel tired, dizzy, and less focused. Make sure you drink enough water throughout the day. A simple trick is to drink a glass of water before each study session to keep your brain active.

5. Take Short Breaks

Studying for too long without a break will only make you less productive. The best way to study for long hours is to break your study time into sessions.

For example, use the 50-10 rule:

• Study for 50 minutes, then take a 10-minute break before continuing.
• After three study sessions, take a longer 30-minute break to refresh.

This will help you study longer without feeling exhausted.

6. Change Your Study Method

If you feel bored or lose focus while reading, try using a different study technique. Instead of just reading your notes, try:

• Practicing past questions – This helps you see what JAMB expects. Check out JAMB 2025: Best Strategies for Answering Maths, English & Science Questions for more tips.
• Explaining what you’ve learned to someone else – This helps you understand better.
• Using flashcards to remember key points quickly.

Changing how you study makes it easier to stay engaged and prevents boredom.

Final Thoughts

Studying for long hours is important if you want to pass JAMB 2025, but if you always feel tired, sleepy, or distracted, then you need to change your approach. Studying for many hours without focus or energy will not help you score high. What matters is how well you study, not just how long you study.

Instead of forcing yourself to read when you’re tired, use smarter study habits that keep you active, focused, and motivated. Get enough sleep, eat the right foods, stay hydrated, take breaks when needed, and use engaging study techniques. When your brain is alert and well-rested, you will understand and remember more in less time.
