5 Ways to Stop Feeling Tired When Studying
Trying to prep for exam season in Singapore comes with its fair share of challenges. If you’ve ever re-read the same paragraph 5 times only to remember exactly none of it, congratulations—you’ve met mental fatigue. And unfortunately, it’s one of the biggest obstacles standing between you and those A’s.
The good news? You don’t need to suffer through it. With the right mix of strategies (and a little help from some natural mental boosters), you can stay sharp, focused, and avoid feeling tired when studying.
Here are 5 ways to beat mental fatigue at your next study sesh.
1. Work With Your Brain, Not Against It
Trying to brute-force your way through 4 straight hours of revision is ambitious—and also wildly ineffective.
Your brain isn’t designed for endless concentration. Studies show that cognitive performance declines when attention is sustained for too long without breaks.¹
Instead, try structured bursts like the Pomodoro Technique:
• 25 minutes of focused study
• 5-minute break
• Repeat
This helps reduce mental fatigue while keeping your productivity surprisingly high. Think of it as interval training, but for your brain.
2. Hydrate Like You Actually Care
Mild dehydration can impair mood, concentration, and overall cognitive performance.² If you’re constantly feeling tired when studying, then you should know that even slightly forgetting to drink water can turn your brain into a sluggish mess.
Before you reach for your 3rd cup of coffee:
• Drink water regularly
• Consider electrolyte support if you’ve been running on caffeine and vibes
Your brain is about 75% water—it’s not being dramatic when it needs a refill.
3. Fuel Up on Natural Mental Boosters
If your diet currently consists of instant noodles and existential dread, we need to talk.
Certain nutrients act as natural mental boosters, helping support brain function and energy levels:
• Omega-3 fatty acids (found in fish, nuts)
• Antioxidants (found in berries, dark chocolate)
• Complex carbohydrates (for steady energy release)
These foods don’t just keep you full—they keep your brain firing on all cylinders and prevent you from feeling tired when studying.
4. Don’t Sleep on… Sleep
Cutting sleep to “make more time” for revision is one of the worst trades you can make.
Sleep plays a critical role in:
• Memory consolidation
• Cognitive performance
• Focus and attention
Pulling an all-nighter might feel productive, but it often leads to poorer recall and slower thinking the next day.³
Aim for 7–9 hours. Your notes will still be there in the morning—your brain, on the other hand, might not be.
5. Tap Into the Benefits of B-Vitamins
Lastly, B-vitamins are essential for energy metabolism and play a key role in supporting brain function.⁴ In simpler terms, they help your body convert food into usable energy—something your brain desperately needs during long study sessions.
Some notable benefits of B-vitamins include:
• Supporting mental performance
• Reducing feelings of tiredness and fatigue
• Helping maintain normal psychological function
Among other benefits, vitamins B1, B6, and B12 are essential for the production of neurotransmitters responsible for regulating mood and mental energy.⁴ Additionally, vitamins B6, B9, and B12 also help to lower homocysteine levels, which can slow down brain degeneration and help to protect against Alzheimer’s disease and other forms of cognitive impairment.
Ultimately, thanks to its benefits for energy production and brain health, incorporating B-vitamin-rich foods (like eggs, leafy greens, and whole grains) or supplements can be a game-changer if you’re consistently feeling tired when studying.
Conclusion: Study Smarter, Not Just Harder
Beating mental fatigue isn’t about superhuman discipline—it’s about using smarter strategies.
With the right combination of the following, you can stay focused, energised, and actually retain what you’re studying:
• Structured study sessions
• Proper hydration
• Natural mental boosters
• Adequate sleep
• And the benefits of B-vitamins
And if you need a quick, convenient boost to power through those pivotal study moments, that’s where 5-hour ENERGY® comes in.
Packed with essential B-vitamins, caffeine sourced from green tea, and zero sugar, it’s designed to deliver lasting energy without the crash. No jitters, no nonsense—just a sharper, more focused you when it matters most.
