Stress causes physical changes in the body designed to help you take on threats or difficulties.

You may notice that your heart pounds, your breathing quickens, your muscles tense, and you start to sweat. This is sometimes known as the fight or flight response.

Once the threat or difficulty passes, these physical effects usually fade. But if you're constantly stressed, your body stays in a state of high alert and you may develop stress-related symptoms.

What causes stress?

Big life changes often create stress, even happy events like having a baby or planning a wedding.

Feeling like you aren't in control of events in your life – for example, if you're diagnosed with a serious illness or you get made redundant – can also cause stress.

Stress may be related to:

·         work – for example, unemployment, a high workload or retirement.

·         family – for example, divorce, relationship difficulties or being a carer

·         housing – for example, moving house or problems with neighbours

·         personal issues – for example, coping with a serious illness, bereavement or financial problems

It's important to tackle the causes of stress in your life if you can. Avoiding problems rather than facing them can make things worse.

But it's not always possible to change a stressful situation. You may need to accept there's nothing you can do about it and refocus your energies elsewhere.

For example, if you're a carer, find ways to take breaks and do the things you enjoy.

When to see your GP about stress

If you've tried self-help techniques and they aren't working, see your GP. There are lots of other options open to you, such as guided self-help or cognitive behavioural therapy (CBT).

You may be able to attend a stress management course. Ask your GP or refer yourself to your local psychological therapies (IAPT) services.
