Stress is a perfectly natural response to the demands and pressures of life. In small doses, some of us find it helpful: it can be motivating, helping us to meet deadlines, to respond more quickly or perform better. However, when stress becomes overwhelming, it can begin to affect both your physical and mental wellbeing.
Understanding the symptoms of stress, learning how to recognise them early, and adopting helpful lifestyle strategies to manage them are important steps to maintaining overall wellbeing.
What is stress?
Stress is the body’s reaction to a demand or challenge. When you perceive a threat (and this can be physical, emotional, or psychological) your body initiates the “fight or flight” response. This leads to the release of stress hormones such as cortisol and adrenaline: they help prepare your body to react quickly.
When we are in ‘fight or flight’ mode for too long, this can lead to a range of symptoms:
Physical symptoms of stress
Stress not only affects your thoughts: it also has a direct impact on your body. Many of us experience physical symptoms without immediately realising that stress may be the underlying cause.
Headaches and muscle tension
One of the most common physical signs of stress is tension in the body. This often manifests as:
- Frequent headaches or migraines
- Tightness in the neck, shoulders, or back
- Jaw clenching or teeth grinding (particularly at night)
This tension occurs because the body remains in a semi-alert state, even when there is no immediate danger.
Fatigue and low energy
Stress can sometimes leave you feeling tired all the time, even after a good night’s sleep. This is because your body is working harder than usual, burning energy to stay alert.
Sleep disturbances
Stress often interferes with your sleep patterns. You may experience:
- Difficulty falling asleep
- Waking up during the night
- Restless or poor-quality sleep
Improving sleep quality can often help reduce other stress-related symptoms, including fatigue and low energy levels.
Digestive issues
Our digestive system is highly sensitive to stress. Have you ever felt sick before an exam, test or interview? This is often your natural stress response affecting how your gut feels.
Common digestive symptoms include:
- Stomach aches or cramps
- Nausea
- Bloating
- Diarrhoea or constipation
- Loss of appetite or overeating
Stress can also disrupt the microbiome – the balance of healthy bacteria in your gut - and affect how you process and digest food.
Increased heart rate and blood pressure
When we are stressed, our heart beats faster and blood pressure rises, delivering more oxygen and nutrients to our muscles.
This is part of the natural ‘fight or flight ‘response as our body gets ready to ‘face the fear or run away’. If this happens frequently, it can put recurring pressure onto our cardiovascular system which can lead to problems further down the line.
Lower immunity
Being stressed can make you more susceptible to illness. You might notice that you:
- Catch more colds or infections
- Are slower to recover from illness
This can happen because stress hormones when activated ongoing, suppress immune function.
Mental and emotional symptoms of stress
Stress can also affect your mental and emotional wellbeing. These symptoms are just as important to recognise and manage as the physical symptoms.
First and foremost, if you are feeling overwhelmed, feel unable to cope, or things feel like they are spiralling out of control, it is important that you talk to someone – a friend, family member or healthcare professional – who can help give you the support you need.

Worrying
Thinking too much about too many things can be a sign that you are under stress. You may feel:
- Overwhelmed by responsibilities
- Unable to relax
- Constantly on edge
Irritability and mood swings
Stress can make you more reactive, and this can be seen in overreacting to things that ordinarily would not cause you frustration. Small annoyances may trigger anger, irritation or emotional outbursts which are not in line with the seriousness of the issue itself. You may also notice general changes in your mood.
Difficulty concentrating
Stress affects cognitive function – our ability to think, plan, and organise – which can make it harder to:
- Focus on tasks
- Make decisions
- Remember information
This can have an impact on your work performance, family responsibilities and daily activities.
Low motivation and burnout
Ongoing stress can lead to a feeling of burnout. This can be reflected in a lack of motivation, emotional exhaustion and/or a reduced sense of achievement even when you are performing well.
You may also begin to step away from activities you previously enjoyed.
Changes in behaviour
Stress can impact our everyday behaviour in different ways:
- Withdrawing from social interactions
- Procrastination (in other words, delaying or postponing activities)
- Increased use of alcohol, caffeine, or other substances
These behaviour changes can increase stress levels further.
How to recognise stress early
Recognising stress early is important when it comes to preventing it from escalating. Many of us get so used to living in a permanent state of stress that we may not notice the warning signs.
Pay attention to patterns
Notice ongoing changes which are out of the ordinary, such as recurring symptoms (headaches, fatigue, or irritability). If these are happening regularly, stress may be the underlying cause.
Listen to your body
Your body will often reflect signs of stress before your mind recognises it. Physical symptoms, tension, or changes in appetite can be early indicators.
Think about your emotional health
Understanding how you are feeling emotionally can alert you to underlying stress.
Ask yourself:
- Am I feeling more anxious than usual?
- Am I reacting more strongly to minor issues?
Changes in emotional responses can indicate increasing stress levels.
Monitor your sleep
Sleep is one of the strongest indicators of overall wellbeing. Persistent sleep problems often mean you are under stress.
How to manage stress
Managing stress doesn’t mean getting rid of it entirely: it would be almost impossible to live without any form of stress. But we can learn how to manage it in healthy ways through lifestyle changes.
Practice relaxation techniques
Simple techniques such as deep breathing exercises, meditation or mindfulness, and progressive muscle relaxation can help to calm the nervous system: even just a few minutes a day can make a big difference to your feelings of stress.
Stay physically active
Exercise is really important when it comes to relieving stress. It helps reduce stress hormones, improve mood, and increases energy levels.
Aim for regular exercise every day, even if it’s just a 10-minute walk. Any way you move your body and keep active will help.
Break tasks into manageable steps
When tasks are mounting up, whether they are work-related or everyday chores, break them into smaller, achievable parts. This makes everything feel more manageable and thereby reduces feelings of stress.
Set boundaries
You’ve heard of a ‘yes man’ or ‘yes woman’: you need to become a ‘no thanks’ person. Learn to say no when necessary: having too many things on your plate can quickly lead to feelings of stress. Protect your personal time, energy, and stress levels by setting clear limits and saying ‘no’ when you need to.
Stay connected
Talking to other people is important when it comes to emotional support and gaining some perspective. Whether it’s a friend, family member, or healthcare professional, sharing your thoughts and feelings can help reduce stress.
Take regular breaks
Continuous work without regular breaks can increase stress levels.
- Short pauses throughout the day help reset your mind and can also help improve productivity.
- If you are desk-based, make sure to get up, move around and get away from your workstation for 5 minutes every hour.
- Use your lunch break for refuelling and moving your body: don’t eat ‘al desko’ – eat away from your workspace and if possible, get outdoors for some fresh air and exercise.
Everyday lifestyle advice to help manage stress
Building a balanced lifestyle that helps you to stay resilient is a great way to manage stress day to day: it’s not all about waiting for difficult and stressful situations to arise. By creating healthy habits which support your mental and physical wellbeing you will be better able to cope with stress when it does happen.
Maintain a healthy routine
Having a consistent routine helps to regulate your body and mind and creates a sense of stability which can help reduce stress.
Try to:
- Wake up and go to bed at the same time each day
- Eat regular, well-balanced nutritious meals
- Schedule time for relaxation every day
Prioritise sleep
Good quality sleep is one of the cornerstones of stress management. Aim for 7-9 hours of sleep per night. To improve sleep quality:
- Avoid smart screens 1-2 hours before bedtime
- Create a relaxing sleeping environment – cool, comfortable and calm
- Stick to a regular sleep schedule
Eat a well-balanced diet
Nutrition is important for our overall health, but it also plays a key role in how your body handles stress. Include:
- Whole foods such as fruits, vegetables, and whole grains
- Lean proteins such as fish, turkey, chicken, eggs, tofu, legumes, and beans
- Healthy fats such as omega 3s found in oily fish, walnuts, flaxseed, chia seed, and nut oils
Spend time outdoors
There is nothing better for relaxing the mind than spending time outdoors. Getting fresh air and surrounding yourself in nature has many benefits:
- Reduces stress levels
- Improves mood
- Enhances focus
Engage in activities you enjoy
Make sure to make time for hobbies, activities and social activities that make you happy. Whether you love playing music, reading, creating art or participating in sports, find what works for you and do it regularly. Enjoyable activities provide an important mental break from stress.
