Discover the hidden physical signs of stress, how they affect your health, and when it’s time to seek help or take time off — even up to the maximum time off for stress UK employees are entitled to.
The physical signs of stress are the ways your body reacts when it’s under constant pressure. These may include headaches, muscle pain, fatigue, digestive issues, or even chest tightness. Stress activates your body’s natural “fight or flight” response — but when it doesn’t switch off, it can harm your long-term health.

Understanding How Stress Shows Up in Your Body
Stress isn’t just in your thoughts — it shows up in your body too. When you’re under constant pressure, your body goes into survival mode, releasing hormones like cortisol and adrenaline. These chemicals prepare you to fight or flee, but when stress becomes ongoing, that response can harm your physical health.
Recognizing the physical signs early can help you act before stress turns into something more serious, like burnout, anxiety disorders, or chronic illness. Let’s explore how your body signals that it’s struggling under pressure.
1. Muscle Tension and Body Pain
One of the most common physical signs of stress is constant muscle tension, especially in the neck, shoulders, and back. You might notice tightness, soreness, or even tension headaches.
When your body stays on high alert, muscles contract continuously, leading to pain and stiffness. Over time, this can cause migraines or posture problems — a clear sign your body is asking for rest.
2. Fatigue and Low Energy Levels
Feeling constantly drained, even after sleeping, is another red flag. Stress interferes with deep sleep cycles and exhausts your energy reserves.
You may find yourself:
- Struggling to get out of bed
- Relying on caffeine to stay awake
- Feeling sleepy but unable to rest properly
If fatigue becomes chronic, it can seriously affect your productivity and focus — a point where your GP might suggest taking time off to recover. In such cases, employees often ask about the maximum time off for stress the UK allows, which depends entirely on your doctor’s assessment and your recovery pace.
3. Headaches and Migraines
Frequent headaches are one of the most noticeable physical symptoms of stress. Stress triggers inflammation and tension in the muscles around the head and neck, often resulting in migraines.
You might experience:
- A pulsing or aching sensation on one or both sides of the head.
- Sensitivity to light or sound
- Nausea during intense headaches
Regular headaches shouldn’t be ignored — they’re your body’s way of warning that stress levels are too high.
4. Upset Stomach and Digestive Issues
Your digestive system reacts quickly to emotional strain. Stress can cause:
- Nausea or stomach cramps
- Constipation or diarrhea
- Increased acid reflux
That’s because the gut and brain are deeply connected — often referred to as the gut-brain axis. When stress hormones flood your system, digestion slows down, leading to discomfort and poor nutrient absorption.
If these symptoms persist, it’s wise to speak to your GP and possibly consider a short break from work to let your system recover.
5. Changes in Appetite and Weight
Stress can drastically affect your eating habits. Some people lose their appetite, while others crave high-sugar or high-fat foods. Over time, this leads to weight fluctuations that can harm both physical and mental health.
Uncontrolled stress eating can also increase the risk of diabetes and heart disease. Tracking your eating patterns can reveal just how much stress is influencing your daily life.
6. Rapid Heartbeat and Chest Tightness
During stressful moments, your heart rate increases as your body releases adrenaline. That’s normal occasionally — but if it happens often, it can feel alarming.
You may notice:
- Heart vibrations
- Chest tightness
- Shortness of breath
If these symptoms appear regularly, it’s crucial to consult your doctor immediately. Continuous stress can raise blood pressure and increase the risk of heart problems. Your GP might even recommend rest or sick leave to prevent burnout or long-term damage.
7. Skin Problems and Hair Loss
Stress can affect your skin and hair health. Conditions like eczema, psoriasis, and acne often worsen during stressful periods. Additionally, prolonged stress may lead to hair thinning or shedding, as your body redirects nutrients away from non-essential functions.
If you’ve noticed sudden skin flare-ups or hair loss, it might not just be external factors — your stress levels could be the root cause.
8. Weakened Immune System
Have you ever noticed that you catch colds or infections more often during stressful times? Chronic stress weakens your immune system by suppressing white blood cell production.
This means your body struggles to fight off bacteria and viruses, leaving you feeling unwell more frequently. Taking proper rest and managing stress are essential to rebuild your immune strength.
When to Seek Medical Help or Time Off
Recognizing the physical symptoms is the first step — acting on them is next.
If you’re experiencing multiple signs consistently, speak to your GP. They can provide a fit note (previously known as a sick note) to sign you off from work for stress.
Depending on your condition, your GP will decide how long you should take off. While there’s no strict maximum time off for stress, UK law defines that your doctor can extend your leave as needed for your recovery. Some people need a week, others several months — it all depends on your health and medical advice.
How to Manage and Reduce Stress Naturally
While medical help is vital, lifestyle adjustments also play a major role in recovery. Here are simple yet effective ways to reduce stress and support your body:
- Prioritize Sleep: Aim for 7–9 hours of quality rest daily.
- Stay Active: Gentle exercises like walking or yoga lower stress hormones.
- Eat Balanced Meals: Focus on fresh fruits, vegetables, and lean proteins.
- Practice Mindfulness: Apps for meditation or breathing exercises can calm your mind.
- Set Boundaries: Learn to say no when workloads become unmanageable.
- Connect with Others: Talking to trusted friends or family eases emotional burden.
Small, consistent habits can make a big difference in how your body handles pressure.
Returning to Work After Stress Leave
When your body and mind have recovered, plan your return to work gradually. Many employers support phased returns, where you work reduced hours at first.
Communicate openly with your manager or HR — they’re legally obligated to make reasonable adjustments under the Equality Act 2010. This ensures you don’t fall back into the same stressful patterns that caused your symptoms in the first place.
