Energy Drinks Before Studying? What Teens Should Know

You get home, open your schoolwork and realise you are running on empty. An energy drink can look like the easiest way to get through the next few hours. Maybe your friends use them. Maybe the can promises focus, and focus is exactly what you want.

Before making it part of your study routine, it helps to know what the drink can do, what it cannot do, and what the warnings actually mean.

Feeling more awake is not the whole picture

Caffeine is a stimulant. It can increase alertness, but feeling awake does not mean you have recovered from too little sleep. The Canadian Paediatric Society explains that caffeine does not reverse every effect of sleep loss on thinking and memory.

There can also be a trade-off. Health Canada lists trouble sleeping, irritability, headaches and nervousness among possible caffeine side effects. That does not mean everyone experiences them, or that caffeine explains every difficult evening. It does mean a drink advertised for focus can deserve a second look when you already feel tense or have trouble sleeping.

What does the research actually show?

A 2024 systematic review of 57 studies looked at energy drink use in children and young people up to age 21. It found associations with shorter sleep, poorer sleep quality and lower academic performance, among other outcomes.

The word association matters. These findings do not establish that an energy drink caused a particular teen's poor grades or sleep problems. Young people who are already tired or under pressure may be more likely to reach for these drinks. Other habits and circumstances may also play a part. The researchers called for further studies to clarify cause and effect.

So the useful takeaway is modest: energy drinks are not an evidence-based solution to the pressures behind a difficult school week.

Read the warning, not just the front of the can

Health Canada's current energy drink guidance explains that labels must identify their high caffeine content and carry cautionary statements, including that they are not recommended for children under 14 or people sensitive to caffeine. That age warning is not a personal assurance of safety for every older teen.

Check how much caffeine is in the whole container. Ingredients such as guarana and yerba mate can be caffeine sources too. Caffeine also occurs in coffee, tea and some other foods and drinks; the energy drink may not be your only source that day.

If you take medication or have a health condition, ask a pharmacist or your healthcare professional about caffeine rather than treating a friend's experience as advice for you. Do not change prescribed treatment to make room for an energy drink.

Make a plan for the problem you are trying to solve

Instead of starting with “How do I push through?”, try naming what is in the way. These are practical planning ideas, not a treatment plan:

• The assignment feels huge: choose one visible starting point, such as reading the instructions and listing what you need to hand in.

• You do not understand the work: write down the exact question to ask your teacher. “I get the first step, but lose track here” is a useful place to begin.

• Your schedule has no breathing room: ask a parent, caregiver or teacher to help you work out what is essential and what can change.

• You are regularly exhausted: tell a trusted adult and consider a healthcare appointment. You do not have to decide on your own why it is happening.

For example, imagine you have two assignments and practice tonight. A realistic plan might be to finish one small section, ask about an unclear instruction tomorrow, and talk with someone about the rest of the week's workload. It does not have to be an all-or-nothing evening.

You can ask for support before things feel unmanageable

If school pressure, worry or feeling stuck keeps getting in the way, you can ask for help with those difficulties. Alberta Teen Counselling's teen counselling page explains the practice's online approach. You can also get in touch to ask whether the service fits your situation.

You deserve a workable routine and support with the pressure behind it. Getting through school should not depend on finding a stronger can.
