Overwhelm: what it is and why it happens

This is the classic kind: work, family, bills and errands all at once. Each task might be small, but together they feel like a wall.

Big news, a loss, conflict or worry can flood you even when your to-do list is short. You might feel tearful, numb or on edge without quite knowing why.

Putting a feeling into words can help. In a brain-imaging study, naming emotions calmed activity in the brain’s alarm area.

Busy places, bright lights, strong smells or constant alerts can push the body into a stress response. Anyone can feel this, though it is more common for some people.

The front part of the brain handles planning, focus and choosing what matters. Research shows it is very sensitive to stress. Even mild stress that feels out of your control can quickly weaken these skills.

That is why, when you are overwhelmed, you might stare at a list and not know where to begin. It is a stress effect, not a character flaw.

Research on working memory suggests that adults can hold only about 3 to 5 meaningful items in mind at once. When you try to keep 20 tasks in your head, things fall off the desk, and it feels chaotic.

Most people know “fight or flight”. Researchers also describe freezing, a state of stillness and holding back that is part of the body’s defence system.

If you go quiet, feel stuck or can’t move forward when overwhelmed, your body may be trying to protect you. Gentle grounding can help you come back.

The NHS lists life changes like moving house, having a baby or bereavement as common causes of stress. Even happy changes bring new demands and fewer routines.

Loneliness and feeling unsupported are listed by the NHS as causes of stress. Research has long shown that support from others can soften the impact of stress.

Illness brings appointments, uncertainty and worry, often on top of everything else. Caring for someone who is unwell adds even more.

Worries about money, housing or work are common causes of stress. They are hard to switch off because they affect where you live, what you eat and what comes next.

Deadlines, exams, care tasks and household jobs can all add up. When the demands rarely ease, overwhelm can become a daily feeling.

NIMH describes stress as a response to an outside cause. It usually eases once the situation is resolved. Overwhelm is often what stress feels like when it piles up.

NIMH explains that anxiety is the body’s reaction to stress and can happen even when there is no current threat. If anxiety lasts and gets in the way of daily life, it is worth talking to a professional.

Overwhelm that builds and builds can sometimes tip into a panic attack. Cleveland Clinic notes that sensory overload symptoms, left unchecked, may lead to one.

The World Health Organization describes burnout as coming from chronic workplace stress that hasn’t been successfully managed. It brings exhaustion, distance or cynicism about the job, and feeling less effective.

Overwhelm can be a warning light on the road to burnout. The NHS notes that stress that feels out of control can lead to exhaustion often called burnout.

The NHS suggests splitting big tasks into smaller ones, noticing when you finish each one, and planning ahead with to-do lists.

• Eat regular meals
• Keep a steady sleep routine
• Limit too much caffeine
• Move your body in ways you enjoy

These won’t remove your stressors, but they help your body and brain handle them.

It can help to ask: “Does this need to be done? By me? Now?” Dropping, delaying or sharing even one thing can make room to breathe.

Studies show people underestimate how likely others are to say yes to a direct request for help, sometimes by as much as half.

Other research found people also underestimate how good helpers feel afterwards. Asking can be a gift to the other person, too.

NIMH suggests noticing and challenging negative, unhelpful thoughts. Try swapping “I have to do everything today” for “I’ll do the next most important thing.”

Writing in a journal can also help you see what is weighing on you.
