Why People Feel Tired Without Physical Effort (B2) – задание на чтение на английском с переводом

People sometimes feel tired after spending most of the day sitting at a desk, attending meetings, studying, or using a computer. Because there has been little physical effort, this tiredness may seem confusing. However, energy is affected by more than movement. Mental work, emotional pressure, poor sleep, constant decisions, and inactivity can all leave a person exhausted.

One important cause is mental overload. The brain uses energy when people concentrate, solve problems, remember details, and switch between tasks. Modern work often requires several of these activities at once. A person may answer messages, listen to a meeting, plan the next step, and worry about a deadline quickly. Although the body is still, the mind is under continuous pressure. By the end of the day, even simple choices may feel difficult.

Emotional stress can be equally tiring. Worry keeps the body in a state of tension, even when no immediate action is needed. Someone may sit quietly while thinking repeatedly about money, relationships, health, or future plans. This inner activity can make relaxation difficult. It may also affect breathing, sleep, and concentration. As a result, people can feel drained without understanding why.

Poor-quality sleep is another common reason. Sleeping for seven or eight hours does not always mean that the body has rested well. Noise, stress, late-night screen use, an uncomfortable room, or an irregular schedule can interrupt deep sleep. A person may wake up several times without remembering it. The next day, they may feel slow and unable to focus.

Lack of movement may also reduce energy instead of saving it. Sitting for many hours can make the body feel stiff and inactive. Gentle movement improves blood flow and helps people become more alert. A short walk, light stretching, or a few minutes outside may therefore be more useful than another hour on the sofa.

Daily habits also matter. Skipping meals, eating very heavy food, drinking too little water, or using too much caffeine can affect energy levels. Sometimes a person believes they need more rest when they actually need water, fresh air, food, movement, or a break from constant information.

For this reason, tiredness should not be judged only by physical activity. Mental effort, emotions, sleep quality, movement, and daily routines all influence how energetic a person feels. Understanding the real cause makes it easier to choose a useful solution instead of simply trying to rest more.
