The reason why I can't concentrate easily, it's simpler than I thought

It may seem like a complicated problem, but in reality, it is often caused by trivial habits or environments in daily life. If you know why your concentration is quickly disturbed, you can increase productivity and immersion even with small changes.
the habit of multitasking
If you try to process multiple tasks at the same time, your brain becomes overloaded and your concentration decreases rapidly. Multi-tasking is likely to be efficient, but it consumes energy to transition work and reduces productivity. Let's make a habit of immersing ourselves in one task at a time. Using the Pomodoro technique, which takes 25 minutes of concentration and 5 minutes of rest, it is easy to maintain short-term concentration. Setting a task priority and writing it as a list can reduce the temptation of multitasking.
lack of sleep
Lack of sleep makes the brain tired, which leads to poor concentration and cognitive function. Lack of sleep reduces short-term memory and thinking skills, making it easy to be distracted by even minor stimuli. Adults are advised to aim for a good night's sleep for 7-8 hours a day. Reduce exposure to smartphone or screen light an hour or two before bedtime, and keep your bedroom dark and quiet. Regular bedtime and comfortable bedding recharge the brain to restore concentration.
digital distraction
Smartphone notifications, SNS, and e-mail are the main causes of distraction. As soon as I check the notification, my immersion breaks, and it takes a lot of time to get back into focus. Turn off your smartphone notifications while you're working, and keep your device out of view. Let's set a digital detox time of 1-2 hours a day to rest the brain. It is effective to use an anti-interference mode or app blocking function for tasks that require concentration.
irregular eating habits
When blood sugar rises and falls sharply, the brain does not receive stable energy, which leads to poor concentration. Sugar-rich snacks or irregular meals cause drowsiness after lunch. Eating regularly and choosing nuts or fruits as a snack stabilizes brain energy. It is also important to drink enough water to prevent dehydration.
lack of exercise
Lack of exercise reduces blood flow to the brain, resulting in poor concentration and cognition. Lack of physical activity makes you easily tired and distracted. Let's practice aerobic exercise such as walking, jogging, and stretching for 30 minutes, three to four times a week. Micro-exercises such as climbing stairs and light stretching for 5-10 minutes in the middle of work are also effective in restoring concentration. Exercise promotes endorphin secretion, increasing mood and immersion.
chronic stress and excessive worry
Chronic stress reduces concentration and flexibility in thinking. Excessive worry makes the brain unable to immerse itself in the current work. Let's calm our minds with 5 to 10 minutes of meditation, deep breathing, or a light walk a day. It is also effective to relieve the burden on your head by organizing what to do with a memo. Stress management is essential for maintaining a clear mind and deep immersion.
improper working environment
Clutter desks, noise, and inadequate lighting interfere with concentration. The distracting environment makes it difficult for the brain to react to unnecessary stimuli and become immersed. Let's tidy up our work space and create a quiet environment. Using headphones or white noise can reduce noise disturbance. Natural light, proper lighting, and comfortable chairs help keep you focused for a long time.
The reason why one's concentration is quickly disturbed is not complicated. Even managing only minor factors can significantly change the quality of immersion.
