Stress: Why Does it Happen?

What is stress?

Stress is our body’s response to pressure. Many different situations or life events can cause stress. It is often triggered when we experience something new, unexpected, or that threatens our sense of self, or when we feel we have little control over a situation.



We all deal with stress differently. Our ability to cope can depend on our genetics, early life events, personality, and social and economic circumstances.



When we encounter stress, our body produces stress hormones that trigger a fight or flight response and activate our immune system. This helps us respond quickly to dangerous situations.


Sometimes, this stress response can be useful: it can help us push through fear or pain so we can run a marathon or deliver a speech, for example. Our stress hormones will usually go back to normal quickly once the stressful event is over, and there won’t be any lasting effects.



However, too much stress can cause negative effects. It can leave us in a permanent state of fight or flight, leaving us overwhelmed or unable to cope. Long term, this can affect our physical and mental health.


What makes us stressed?

Many things can lead to stress: bereavement, divorce or separation, losing a job, or unexpected money problems. Work-related stress can also harm your mental health. People affected by work-related stress lose an average of 24 days of work due to ill health.



Even positive life changes, such as moving to a bigger house, gaining a job promotion, or going on holiday can be sources of stress. If you feel stressed in these situations you may struggle to understand why or be unwilling to share your feelings with others.



What are the signs of stress?


You may feel:



angry or aggressive





These feelings can sometimes produce physical symptoms, making you feel even worse.



You may behave differently if you’re stressed. You may:

Smoke, drink alcohol, or take drugs more than usual.

How your body might react



If you’re stressed, you may experience:




Shallow breathing or hyperventilating


Heart palpitations

Aches and pains.

If the stress is long-lasting, you may notice your sleep and memory are affected, you’re eating habits change, or you feel less inclined to exercise.



Some research has also linked long-term stress to gastrointestinal conditions like Irritable Bowel Syndrome (IBS) or stomach ulcers, as well as conditions like cardiovascular disease.



Who is affected by stress?

All of us can probably recognize some of the feelings described above. Some people seem to be more affected by stress than others. For some people, getting out of the door on time each morning can be a very stressful experience, whereas others may be less affected by a great deal of pressure.


Some people are more likely to experience stressful situations than others. For example:


People with a lot of debt or financial insecurity are more likely to be stressed about money

People from minority ethnic groups or who are LGBTIQ+ are more likely to be stressed about prejudice or discrimination

People with disabilities or long-term health conditions are more likely to be stressed about their health or the stigma associated with their condition.



How can you help yourself?

  1. Recognise when stress is a problem

It’s important to connect the physical and emotional signs you’re experiencing to the pressures you are faced with. Don’t ignore physical warning signs such as tense muscles, tiredness, headaches, or migraines.


Think about what’s causing your stress. Sort them into issues with a practical solution, things that will get better with time, and things you can’t do anything about. Take control by taking small steps towards the things you can improve.


Make a plan to address the things that you can. This might involve setting yourself realistic expectations and prioritizing essential commitments. If you feel overwhelmed, ask for help and say no to things you can’t take on.



  1. Review your lifestyle

Are you taking on too much? Could you hand over some things to someone else? Can you do things in a more leisurely way? You may need to prioritize things and reorganize your life so you’re not trying to do everything at once.



  1. Build supportive relationships

Find close friends or family who can offer help and practical advice that can support you in managing stress. Joining a club or a course can help to expand your social network and encourage you to do something different. Activities like volunteering can change your perspective and have a beneficial impact on your mood.



  1. Eat healthily

A healthy diet can improve your mood. Getting enough nutrients (including essential vitamins and minerals) and water can help your mental wellbeing.



  1. Be aware of your smoking and drinking

Cut down or cut out smoking and drinking if you can. They may seem to reduce tension but make problems worse. Alcohol and caffeine can increase feelings of anxiety.



  1. Exercise

Physical exercise can help manage the effects of stress by producing endorphins that boost your mood. Even a little bit of physical activity can make a difference, such as walking for 15-20 minutes three times a week.



  1. Take time out

Take time to relax and practice self-care, where you do positive things for yourself. Striking a balance between responsibility to others and responsibility to you is vital in reducing stress levels.



  1. Be mindful

Mindfulness meditation can be practiced anywhere at any time. Research has suggested it can help manage and reduce the effect of stress and anxiety.



  1. Get some restful sleep

If you’re having difficulty sleeping, you can try to reduce the amount of caffeine you consume and avoid too much screen time before bed. Write down a to-do list for the next day to help you prioritize, but make sure you put it aside before bed. For more tips on getting a good night’s sleep, read our guide ‘How to sleep better.



  1. Don’t be too hard on yourself

Try to keep things in perspective and don’t be too hard on yourself. Look for things in your life that are positive and write down things that make you feel grateful.



Get professional help:

If you continue to feel overwhelmed by stress, don’t be afraid to seek professional help. It doesn’t mean you’re a failure. It’s important to get help as soon as possible so you can start to feel better.


Talk to your doctor about how you’re feeling. They should be able to advise you on treatment and may refer you for further help. They may suggest talking therapies such as:

Cognitive Behavioral Therapy (CBT), which can help reduce stress by changing the ways you think about stressful situations.

Brief interpersonal counseling, which can give you the chance to talk about what causes you stress and develop coping strategies Mindfulness-based approaches.
