Jogging and health: why running changes your body and mind for the long term
Alongside cycling, jogging is one of the most popular endurance sports, and for good reason. Many people run to get fitter, to reduce stress or simply to clear their head. Perhaps you know this feeling yourself: after a run you are physically tired, but at the same time full of energy, more balanced and mentally clearer.
This feeling does not arise by chance. Regular running training influences your body on several levels at once, from your cardiovascular system and your muscles to your mind and your nervous system.
What matters here:
The positive adaptations never work in isolation. Your whole organism reacts to movement.
EFFECTS ON THE BODY (PHYSIOLOGY)
Just 3 running sessions a week at moderate intensity of about 30–40 minutes can bring about noticeable health changes.
Adaptations of the cardiovascular system
Regular jogging strengthens your heart in the truest sense of the word.
Endurance training increases the volume of the heart. This is known as the so-called "athlete's heart". It does not mean that your heart is diseased, but that it works more efficiently and can pump more blood with each heartbeat.
In trained elite athletes, up to 40 litres of blood per minute can be pumped under maximal load. In recreational athletes, the values are usually between 23–25 litres.
Further positive adaptations:
- increased blood volume
- more red blood cells and haemoglobin
- improved capillarisation of the muscles
- better oxygen supply to your muscle cells
- higher oxygen uptake capacity
- improved buffering capacity against acidification
Your body therefore works more efficiently, both in sport and in everyday life.
Adaptation of the respiratory system
With improved heart performance, your breathing changes too.
Minute ventilation rises markedly. At the same load, trained people can take in and process much more oxygen.
As a result, the following happens:
- your respiratory muscles become stronger
- your breathing becomes more economical
- oxygen shortages can be compensated better
- CO₂ is removed more efficiently
You can cope with more load and tire less quickly.
Changes in the muscles
For muscles to work, they need energy and oxygen. This is exactly where regular running training comes in.
Thanks to the improved blood flow, your muscle cells form more so-called mitochondria, the "power plants" of your cells.
The more mitochondria there are, the more efficiently your muscles work.
Further effects:
- slower lactate formation
- faster lactate clearance
- better muscular load tolerance
- promotion of muscle growth and recovery
Your muscles therefore become not only more capable, but also more resilient.
Effects on the immune system
During exercise, your body releases so-called myokines. These messenger substances are produced in the muscle cells and, among other things, are:
- anti-inflammatory
- immune-strengthening
- metabolism-regulating
Regular endurance training can therefore:
- reduce your susceptibility to infections
- improve your resistance to cold and heat
- strengthen your immune defences
Exercise is therefore not just training, but active health promotion.
Effects on the autonomic nervous system
The autonomic nervous system regulates many unconscious processes such as:
- heart rate
- digestion
- stress reactions
- recovery
A distinction is made between:
- the sympathetic nervous system (stress/activation mode)
- the parasympathetic nervous system (rest/recovery)
In the long term, regular jogging promotes parasympathetic activity.
This means:
- better recovery
- a lower resting heart rate
- more balanced blood pressure regulation
- fewer stress hormones
Many people notice this not only physically, but also emotionally:
They feel calmer, more resilient and mentally more stable.
EFFECTS ON THE MIND (PSYCHOLOGY)
Jogging does not change only your body, but also your mind.
During running, numerous hormones and neurotransmitters are released:
- Endorphins
- Endocannabinoids
- Dopamine
- Serotonin
These substances directly influence your wellbeing and can trigger the well-known "runner's high".
Perhaps you know this feeling:
You set off tired or stressed, and come back with a clear head, a better mood and new energy.
Positive psychological effects of running
Regular jogging can:
- reduce stress
- improve concentration
- lower pain perception
- increase attention
- promote memory and cognitive abilities
Many runners also describe the training as a kind of meditative state:
Focusing on your breathing, movement and surroundings creates mental calm and distance from everyday life.
Still important: start slowly
As healthy as jogging is, too much, too fast or with unclean technique can cause problems.
Many beginner runners make the same mistake:
They start highly motivated, increase volume or intensity too quickly and so overload joints, muscles or tendons.
Typical consequences:
- Achilles tendinopathy
- Plantar fasciitis
- Knee complaints
- Muscle injuries
- Overuse pain
That is why:
Good running training does not consist of running alone.
Also important are:
- Strength training
- Trunk stability
- Running technique
- Recovery
- Load management

Our goal:
That you can run healthily, efficiently and with joy in the long term, whether you are a beginner or an ambitious runner.
FAQ: Jogging and health
1. How often should I jog to feel the health benefits?
Just 3 moderate running sessions a week of 30–40 minutes each can have positive effects on the heart, metabolism and mind.
2. Is jogging bad for the joints?
No. Properly dosed running training is usually not harmful for healthy joints. Technique, load management and recovery are what matter.
3. Why do I often feel better after jogging?
Exercise releases endorphins, dopamine and other messenger substances that have a positive effect on mood, stress levels and wellbeing.
4. What is the "runner's high"?
A state of euphoria or mental clarity during or after prolonged endurance exercise, triggered by the body's own messenger substances.
5. When does a running analysis make sense?
With pain, recurring injuries, when starting to run or when aiming to improve performance, a professional analysis can help to identify incorrect loading early.
