Quick answer
What is stress?
Stress is the body's response to pressure. A little can be motivating, but too much for too long affects your mind, body, mood and sleep. Practical steps — being active, talking to someone, planning your time and reducing alcohol and caffeine — help most people. See a GP if stress feels constant, affects your health, or you cannot cope.
What is stress?
Stress is how we react when we feel under pressure or threatened. It usually happens when we are in a situation we do not feel we can manage or control. A certain amount of stress can be useful — it can help you stay focused before a deadline or react quickly. But when stress is too intense, or goes on for too long, it can start to affect your mind and body.
Stress is not a medical condition in itself, but it can lead to mental health problems such as anxiety and depression, and contribute to physical illness. The good news is that there is a lot you can do to manage it.
Recognising the signs
Stress shows up differently for everyone. You might notice:
In how you feel and think:
- feeling overwhelmed, worried or anxious
- being irritable, tearful or low
- racing thoughts, or finding it hard to concentrate or make decisions
In your body:
- headaches or muscle tension
- a churning stomach or changes in appetite
- tiredness and trouble sleeping
- a faster heartbeat
In what you do:
- snapping at people
- drinking, smoking or eating more than usual
- withdrawing from others
Burnout — when stress goes too far
When stress builds up over a long time without relief — often from work or caring responsibilities — it can lead to burnout. Signs include:
- feeling exhausted and emotionally drained
- becoming cynical, detached or negative about your work
- feeling that nothing you do makes a difference
- reduced performance and motivation
Burnout is a signal that something needs to change. Rest, support and adjusting what is being asked of you matter more than simply trying harder.
How to reduce stress
Small, consistent changes make the biggest difference:
- Be active — physical activity is one of the most effective stress relievers.
- Connect — talking to friends, family or a colleague eases pressure and puts problems in perspective.
- Take control — break problems into smaller steps and focus on what you can change.
- Plan your time — prioritise, and accept that you cannot do everything at once.
- Look after the basics — sleep, regular meals, and cutting down on alcohol, caffeine and nicotine.
- Make time to relax — mindfulness, breathing exercises, hobbies and time outdoors all help your nervous system settle.
Stress at work
Work is one of the most common sources of stress. Take regular breaks, be realistic about what you can take on, and talk to your manager early if you are overloaded — employers in the UK have a legal duty to manage work-related stress. Protect time away from work and use your holiday.
Getting support
If stress feels constant, is affecting your health or sleep, or you feel unable to cope, see a GP. They can check whether anxiety or depression is involved and talk through support, including NHS talking therapies. Asking for help early makes it easier to turn things around.
Some people find apps and online tools helpful alongside NHS care. brightloaf is a UK mental health app focused on practical support for anxiety, with check-ins, short educational tools, and access to counselling sessions.

Common questions about stress
- What are the symptoms of stress?
- Stress can affect your mind and body. You may feel overwhelmed, anxious, irritable or low, and struggle to concentrate or switch off. Physical signs include headaches, a racing heart, tense muscles, tiredness, an upset stomach and trouble sleeping. You might also eat more or less than usual, or drink more alcohol.
- How can I reduce stress?
- Helpful steps include being physically active, getting outdoors, keeping a routine and good sleep, and talking to someone you trust. Break big tasks into smaller ones, decide what you can and cannot control, and cut down on alcohol, caffeine and nicotine. Breathing exercises, mindfulness and making time for things you enjoy all help too.
- What are the signs of burnout?
- Burnout is the result of long-term, unmanaged stress, often from work. Signs include feeling exhausted and drained, becoming cynical or detached from your job, reduced performance, and feeling that nothing you do makes a difference. Physical exhaustion, poor sleep and frequent illness are common. Burnout needs rest and change, not just pushing through.
- How do I cope with stress at work?
- Try to take regular breaks, set realistic limits on your workload, and be clear about what you can deliver. Talk to your manager early if you are overloaded — UK employers have a duty to manage work-related stress. Protect time away from work, and use your annual leave. If work stress is affecting your health, see a GP.
- What is the best vitamin for stress and anxiety?
- There is no vitamin proven to treat stress or anxiety, and supplements are not a substitute for managing the causes or getting help. A balanced diet usually provides what you need. Low vitamin D or B12 can affect mood, so a GP may test for these if you have symptoms. Always check with a pharmacist or GP before taking high-dose supplements.
- When does stress become a medical problem?
- Stress itself is not a mental health condition, but ongoing stress can trigger or worsen anxiety, depression and physical health problems such as high blood pressure. If stress is constant, stops you functioning, affects your body, or you cannot cope, treat it as a reason to see a GP — it is not a sign of weakness.
