Have you noticed yourself checking your phone every few minutes? Or catching yourself absent-mindedly scrolling through one form of entertainment after another while you work? You might put it down to post-pandemic brain fog, or the early signs of getting older. But a shrinking attention span is this generation's collective symptom: across the past few decades, the public's attention span has been trending sharply downward. According to research from the United States, the length of time we can stay focused fell from 2.5 minutes in 2003 to just 47 seconds by 2019. There are many reasons behind this decline, but the advance of technology is one of the most important factors.
How "fast-food" content affects our focus
In this digital age, phones, computers and audio-visual media offer a constant, unending stream of stimulation. Novelty after novelty easily captures our attention, and since the pandemic our dependence on technology has only grown. We have cultivated the habit of concentrating only in short bursts. To capture our attention, platforms for entertainment, film and news have steadily shortened and sped up their content, so that we digest it ever more quickly.
Today's ubiquitous "five-minute reads" and "three-minute explainers" and other bite-sized content break information down into instantly digestible fragments, letting us take in as much as possible in the shortest possible time. Every time we complete a task — finishing a clip, say, or picking up a piece of information — dopamine is released as a kind of social reward, bringing a feeling of pleasure and satisfaction. The more concentrated the information online becomes, the more our brain keeps releasing dopamine, which in turn means we get that fleeting sense of satisfaction very quickly. This gradually erodes our patience: we become unwilling to spend more time to obtain information, which reinforces our habit of constantly checking our phones.
How can we train our focus?
Although all these distractions may have weakened our focus, attention can in fact be trained back.
1. Do one thing at a time
We tend to overestimate our ability to multitask, believing that handling several things at once makes us more efficient. In reality, the human brain is not built to carry out multiple tasks simultaneously. When we try to do several things at once, the brain simply keeps switching back and forth between different tasks, or drops one task to take up another. When we juggle multiple tasks, the prefrontal cortex network in the brain needs time to reorganise and adapt each time, which creates a greater load. This harms our cognitive abilities, drains our mental resources, and raises the likelihood of making mistakes. On top of that, abruptly switching tasks scatters our attention and disrupts the focus we already had, lowering overall productivity.
By contrast, if we concentrate on one thing, our efficiency improves and our focus is strengthened in the process. For example, we can rank our work by importance, tackle the priorities first, and complete them one by one. When we concentrate on doing one thing at a time, we avoid basic mistakes and use up less mental energy.
2. Time-management techniques
By using time-management techniques, we can allocate tasks more effectively and so improve our productivity. Readers can try the following time-management techniques:
The Pomodoro Technique
- Work for 25 minutes, rest for 5 minutes, then repeat
- Complete the task with full concentration during each work block
Why it works:
- 25 minutes is relatively short, making it easy to stay highly engaged, which helps maintain focus and the motivation to work.
- Regular short breaks help to avoid fatigue and over-exertion
Time Blocking
- Divide the day into different blocks of time
- Assign a specific task to each block
Why it works:
- It helps you manage your time better and concentrate your mental energy
Time-management techniques are mainly about increasing the balance between work and rest. Taking regular breaks and recovering your energy is essential for maintaining attention and productivity. Whether these techniques work, however, also depends on the individual. For people with good self-regulation or a high degree of self-discipline, who can already control their attention and behaviour effectively, there is less need to rely on external blocking tools. For them, such tools may even restrict their normal rhythm of work and life, becoming a redundant constraint.
3. Reduce distractions
Our working environment often contains plenty of distractions, such as a ringing phone or an incoming email, which easily scatter our attention. Simply keeping the environment quiet and tidy, and reducing sensory stimulation such as sights and sounds, lowers the burden on the brain of processing all this noise, makes it easier to enter a state of deep work, and helps sustain a high level of focus over longer periods. For example, if you usually work in your own room, there may be plenty of distractions. You could try going somewhere quieter to work, such as a library or another corner of the home, or switching your phone to silent mode.
4. Improve your lifestyle habits
Roughly how many hours of sleep do you usually get? Does the food you eat give you enough nutrition? Good lifestyle habits are highly effective for maintaining and boosting focus, keeping the brain in its best condition. When it comes to diet, we should eat highly nutritious foods, such as fish oil and vegetables. As for rest, people need eight hours of sleep a day. A lack of sleep builds up a sleep debt, which in turn affects focus. Sleep deprivation and accumulated fatigue do even more serious harm to how the brain functions. Practising mindfulness meditation and relaxation exercises regularly can train the brain's focus and strengthen self-regulation. Research has found that building these healthy habits not only improves productivity but also promotes mental health, helping to sustain concentration over the long term.
The many temptations of daily life are indeed hard to avoid. They often leave us feeling restless and distracted, with a cluttered mind, making it hard to focus on the task in front of us. But we must never passively accept this diet of "fast-food" information; we have to break the habit of concentrating only in short bursts. We should learn to manage our attention well, so that we can lift our productivity and sense of achievement at work or in our studies.
