It helps with some kinds of work and gets in the way of others. That sounds like a dodge, so let us be specific. There is real research behind the feeling that you get more done in a cafe, and it points to three things: the noise, the other people, and the coffee. Each one helps in a particular way, and knowing which is which will tell you when to go and when to stay home.
Why do people study in cafes in the first place?
Mostly to get away from the bed. At home there is laundry, a phone charger next to a pillow and a family that knows where you are. A cafe gives you a small table, a bill you have already paid and nothing else to do. Getting dressed and travelling there is also a commitment, and commitments are easier to keep than intentions.
Does background noise really help?
For creative work, a moderate amount seems to. A 2012 paper in the Journal of Consumer Research by Ravi Mehta, Rui Zhu and Amar Cheema ran five experiments and found that a moderate level of ambient noise, about 70 decibels, improved performance on creative tasks compared with a low level of about 50 decibels. A high level of 85 decibels hurt creativity. Their explanation is that a little noise makes thinking slightly harder, which nudges you into more abstract thinking.
Does that mean noise helps with memorising?
No, and this is the part people miss. Those experiments tested creative tasks, not memorisation or problem sets. If you are drafting an essay, planning a thesis chapter or brainstorming a design, a humming cafe may suit you. If you are memorising drug names or working through calculus, quiet is usually the safer bet. Our list of the quietest cafes in Marikina is for those days.
Do other people working nearby make a difference?
It seems so. A BBC Worklife feature by Bryan Lufkin on why we feel more creative in coffee shops describes this as a social-facilitation effect. Seeing other people working puts you in the mood to work too, a bit like going to the gym instead of exercising alone in your room. The same piece points to visual variety as a third ingredient: people coming and going, the light changing, a room that is not the one you stare at every day.
How much of it is just the coffee?
Some of it, though less than we like to think. A review we cover in our article on coffee and focus found that caffeine doses of roughly 40 to 300 milligrams improve alertness, vigilance, attention and reaction time, with less consistent effects on memory and higher-order judgment. In other words, coffee helps you stay on the page. It does not do the understanding for you.
Does coffee improve memory?
Not reliably. A review summarised in our article on coffee and memory concluded that caffeine usually does not affect learning and memory tasks, and helps mainly when your alertness is below par. So a coffee can rescue a sleepy afternoon. It will not make a well-rested brain remember more, and it certainly does not replace the sleep that fixes memories in place.
Does it work the same way for everyone?
No. The BBC piece notes that the right level of background noise is different for each person, which matches what most of us have noticed about our own friends. Some people cannot read a paragraph with music on. Others cannot work in silence. Coffee is personal too. In one study of 369 people, caffeine improved alertness in regular drinkers mainly by reversing overnight withdrawal, and did little for people who did not usually have it. We cover that in our article on why coffee sometimes stops working. So if a cafe session does nothing for you, that is useful to know, not a failure.
Does it help to go with a friend?
It can, for the right kind of work. The same BBC piece points out that cafes suit small groups who are brainstorming, because meeting over coffee feels less formal than a scheduled meeting and needs no agenda. For reviewing together or talking through a project, that looseness helps. For reading and memorising, a friend across the table is one more thing to look at. Go together, then agree on an hour of silence.
When does studying in a cafe make things worse?
When the room is too loud, when your task needs silence, or when you spend the session watching people instead of reading. A cafe during a live gig or a weekend rush is closer to the 85-decibel end of that research than the helpful middle. Cafes are also poor places for recorded lectures, online exams and anything that needs you to speak. For those, a library or a study hub wins. Our study hub versus cafe comparison covers the trade-off.
How do you get the benefit without the distraction?
Match the task to the place. Take creative and planning work to a cafe, and take memorising to somewhere quiet. Sit facing a wall if people-watching is your weakness. Decide what you will finish before you order, and keep the session to two or three hours, since that is about how long the novelty lasts. And change shops now and then. Part of the effect is the freshness of the room.
Is it fair to the cafe?
It is, if you hold up your end. Order regularly, take a small table and give it up when the shop is full. We set out the whole thing in our guide to whether it is rude to study in a cafe. If you are choosing where to go in Marikina, our main guide to study-friendly cafes is the place to start, and our guide to coffee for late-night studying covers what to order once you are there.
