Stress is the body's natural response to stress - but when stress becomes prolonged, it begins to affect health deeply. From headaches and muscle pains to sleep problems, stomach problems and exhaustion - long-term stress is behind a large part of the problems that Swedes seek a doctor for today.
In this article, we go through what stress does to the body, which symptoms you should pay attention to, how stress is linked to both pain and headache, and how to get the right help in time.
What is stress?
Stress is the body's reaction to demands and threats - real or perceived. In acute stress, adrenaline and cortisol are released, the heart rate increases, the muscles tense and the brain goes on alert. It is helpful in the short term but harmful if it becomes chronic.
Acute stress vs. chronic stress
- Acute stress – short-lived, the body recovers quickly
- Chronic stress – lasts weeks, months or years, the body does not have time to recover
- Exhaustion syndrome – the final stage of prolonged stress, often requiring long rehabilitation
Common symptoms of stress
Stress manifests itself throughout the body – physically, mentally and behaviorally.
Physical symptoms

How stress affects the body
Understanding the connection between stress and physical ailments is important - too many people seek pain relief without knowing that stress is the root cause.
Stress → tension headache
Under stress, you unconsciously tense your jaw muscles, neck and shoulder muscles. The result: a throbbing headache across the forehead or back of the head. Read more about headaches and migraines.
Stress → muscle pain
Chronic muscle tension causes pain in the neck, shoulders and back. The muscles become sore, stiff and tired. Over time this can develop into chronic pain.
Stress → lowered pain threshold
Prolonged stress causes the nervous system to become hypersensitive. Pain that was previously bearable can now be experienced much stronger. This is central to fibromyalgia and chronic pain.
Stress → sleep disturbances → more pain
Stress disrupts deep sleep. Without deep sleep, the muscles cannot recover, the pain threshold drops further – a vicious circle occurs.
Stress → upset stomach
The brain and gut communicate directly (gut-brain axis). Stress can cause IBS, nausea and constipation.
Common causes of stress
- Workload – fast pace, unclear requirements, poor management
- Relationships – conflicts in family, partner, colleagues
- Finance – debts, uncertainty
- Health – own or a loved one's illness
- Life events – divorce, death, moving
- Digital stress – constant connection, social media
- Perfectionism and unrealistic demands on oneself
When should you seek help?
Contact a doctor if you:
- Have stress symptoms that have lasted for more than 3-4 weeks
- Has severe fatigue that does not go away with rest
- Experiencing panic attacks or recurring worries
- Have sleeping problems more than a few nights a week
- Have muscle aches or headaches daily
- Noticing concentration difficulties that affect work
- Feeling close to exhaustion
Treatment of stress and stress-related disorders
Treatment is always individual but usually combines several parts:
Lifestyle and behavior change
- Sleep – 7-9 hours, regular times
- Exercise – 150 min/week, preferably outdoors
- Diet – regular meals, reduce sugar and caffeine
- Breathing exercises and meditation
- Digital breaks – screen-free time daily
- Social contacts – isolation exacerbates stress
Talk therapy
CBT (cognitive behavioral therapy) has strong scientific support for stress, exhaustion and anxiety. Focuses on thought patterns, behaviors and recovery.
Medical assessment
A general practitioner can:
- Rule out other medical causes (thyroid, blood values, vitamin deficiency)
- Assess the need for sick leave
- Refer to a psychologist or specialist
- Treat sleep problems and anxiety if necessary
Physical treatment
For stress-related neck pain, back pain or headache physiotherapy, massage and ergonomic improvements can make a big difference.
Self-help – what you can do now
- Breathing exercises – The 4-7-8 technique (inhale 4s, hold 7s, exhale 8s)
- Daily walks – 30 minutes, preferably in nature
- Limit caffeine – max 2–3 cups of coffee per day, nothing after 2pm
- Reduce screen time – especially 1 hour before bedtime
- Prioritize sleep – same times every day
- Say No – protect your energy
- Ask for help – stress is nothing to be ashamed of
Frequently asked questions (FAQ)
Can stress cause physical pain?
Yes. Long-term stress increases muscle tension, lowers the pain threshold and disrupts sleep - which together causes headaches, neck and shoulder pain and diffuse pain in the body.
Can stress cause headaches every day?
Yes. Stress is one of the most common causes of tension headaches and can also trigger migraines. Many people with daily headaches have chronic stress as a basis. Read more about headache every day.
What is the difference between stress and exhaustion syndrome?
Stress is a reaction to strain. Fatigue syndrome is a condition diagnosed after prolonged stress, with pronounced fatigue, cognitive impairment and physical symptoms that have lasted for at least 6 months.
How long does it take to recover from prolonged stress?
Mild stress can subside in a few weeks with lifestyle changes. Fatigue syndrome often requires 6–24 months of rehabilitation. Early help shortens recovery dramatically.
Can you work out stress?
Regular exercise is one of the most effective ways to reduce stress. Aerobic exercise lowers cortisol, improves sleep and increases endorphins. But in case of exhaustion, you should start carefully - because hard training can make it worse.
Do I need a referral to see a doctor in case of stress?
No. At the Scandinavian Health Clinic in Mölndal, you book an appointment directly with a general practitioner or specialist without a referral, usually within a few days.
How do I know that the stress has gone too far?
Warning signs are daily headaches or muscle aches, persistent sleep problems, heart palpitations, difficulty concentrating and a feeling of "not being able to take it anymore". With these signs, you should seek care before it develops into exhaustion syndrome.
Does mindfulness really help with stress?
Yes. Research shows that regular mindfulness reduces cortisol levels, improves sleep and lowers both anxiety and pain perception. 10-20 minutes daily is enough for clear effects within 8 weeks.
Summary
Stress is not just a feeling – it is a bodily reaction that over time can cause serious physical ailments. Headaches, muscle aches, sleep problems and exhaustion are often the body's way of saying no. Listening in time - and seeking help when problems persist - is crucial.
