For a long time, I believed that multitasking was some kind of superpower. That doing several things at once made me more efficient, faster, and able to fit more into my day. Working a lot from home only pushed me to juggle even more tasks simultaneously, even during my short lunch breaks. Sometimes I’d reply to emails while eating, respond to messages, and already plan my next task. But eventually, I started asking myself: is this really effective? Or does it just look like I’m doing a lot at once?
Psychological research shows that our brains can’t truly multitask. Instead, it’s a series of rapid switches that drain a lot of energy.
Our Brain Doesn’t Like Jumping Between Tasks
Every time we switch from one task to another, our brain needs to "recalibrate". This process takes time and energy. That’s why, by the end of a day filled with multitasking, we often feel more exhausted than if we had tackled tasks one by one. When we split our attention, each task gets less focus, which can lead to mistakes. Fixing those errors ends up taking even more time.
Multitasking Diminishes Focus
Constant interruptions make deep focus much harder. And deep focus is often the key to getting things done well. With constant attention shifts, our brain becomes scattered over time.
Rest Disappears From the Day
One hidden risk of working from home is that boundaries easily blur. Lunch breaks turn into quick email replies, and short rests become more tasks. But rest isn’t wasted time. On the contrary, real breaks recharge our energy.
The Illusion of Constant "Busyness"
When we do many things at once, we often feel very productive. But this is often just an illusion. We might be busy with many small tasks while making slow progress on what really matters.
It Can Easily Lead to Burnout
Splitting our attention in many directions is mentally exhausting in the long run. Constant switching tires the brain and can easily cause overwhelm. That’s why it’s so important to pause sometimes and ask if doing everything at once is really necessary.
Where’s the Limit?
Maybe the toughest question is: how do we know when multitasking stops being helpful and starts wasting energy?
One sign is feeling busy all day but not really making progress by the day’s end.
Another is when our attention is scattered and we struggle to focus on any one task. That’s a good moment to pause and ask: what’s the one thing I really need to focus on right now?
How to Set Boundaries?
Setting boundaries often starts with small steps. Like focusing on one task at a time or truly treating lunch breaks as breaks. Sometimes it helps to consciously allow ourselves not to respond immediately to everything. Multitasking tempts us because it feels like we’re accomplishing more. But often the opposite happens: we burn more energy and make less real progress. Sometimes the simplest solution is the most effective: focus on one thing at a time.
