Understanding anxiety
Anxiety, explained without the jargon
Anxiety is one of the most common reasons people seek therapy, and one of the most misunderstood experiences there is. These guides cover what anxiety actually is, why it turns up when it does, and what tends to help — gathered in one place.
Where to start
Anxiety is uncomfortable, but it isn't random
At its simplest, anxiety is the mind and body preparing for threat. It tries to protect, predict and prevent harm — which is why it so often shows up as urgency, scanning and a body braced for something. The difficulty comes when that protective system becomes overactive, and ordinary things start being treated as danger.
A great deal of the distress in anxiety comes from not understanding it. When the sensations seem to arrive from nowhere, it's natural to wonder whether something is seriously wrong. Understanding what anxiety is doing tends to make it feel less mysterious — and makes it easier to judge when support would be useful. The guides below work through it from the ground up.

Questions people ask about anxiety
- What is anxiety?
- Anxiety is the mind and body preparing for threat — a protective system designed to predict and prevent harm. It shows up as a mix of thoughts (scanning, worrying, seeking certainty) and physical sensations (a fast heartbeat, tight chest, shallow breathing, tension). It becomes a difficulty when that system stays switched on, or starts treating ordinary situations as dangerous. There's more in your guide to the anxiety response.
- Why do I feel anxious for no reason?
- Anxiety often seems to arrive without a trigger, but it's usually responding to something — accumulated stress, a body already in a state of readiness, or a thought that passed too quickly to notice. The mind then looks for a reason, and worry fills the gap. This is explored in why am I anxious for no reason.
- Why is my anxiety worse at night?
- During the day there's structure and distraction. At night there's less of both, so the mind turns towards unfinished thoughts — often while tiredness has reduced perspective. Over time the bed itself can become associated with bracing and scanning. See why anxiety feels worse at night and on waking.
- What helps with anxiety in the moment?
- Rather than one perfect technique, people generally find small repeatable habits more useful — naming what's happening, slowing the out-breath, lowering the demand to solve everything at once, and reducing repeated checking. Grounding techniques and ten evidence-based tools cover approaches in more detail. These create steadier conditions rather than removing anxiety.
- When should I see a psychologist about anxiety?
- It may be worth considering if anxiety is disturbing your sleep most nights, leading you to avoid work, study, relationships or ordinary tasks, causing repeated panic, or leaving you exhausted and unlike yourself. You don't need to prove things are bad enough first. If anxiety is narrowing your life, that is reason enough — more on the signs.
- What therapy works for anxiety?
- Cognitive behavioural therapy (CBT) has the strongest evidence base for anxiety, and compassion-focused and acceptance-based approaches are also widely used. Which fits depends on what's maintaining the anxiety for you — a psychologist will build that understanding with you rather than applying a technique first. See the ultimate guide to CBT.
