Everything is demanded of our body every second. The blood sugar level must keep pace with the energy requirement, the electrolytes must be distributed so that cells do not burst and the blood flow should adapt to the current load. The big concept behind all these processes is calledhomeostasis.

This is about maintaining a stable environment in the body. Regardless of whether it is sport, infection, stress, sleep or food - our organism tends to restore the original balance with every downward or upward deflection. At the cellular level, enzymes and other proteins master the task. The endocrine system uses hormones to regulate larger cell groups and even entire organs (z.B: pancreas, ovaries, thyroid gland).

The nervous system also contains the control box for things such as body temperature, stress response and respiration. When the body gets out of balance, the consequences are all too noticeable: Diabetes, arteriosclerosis, dysbiosis, faster biological ageing. However, each and every one of us can throw a few more or less heavy weights into the balance so that balance does not remain the exception to the rule.

Nothing runs in our body without our fantastic miniature power plants, the mitochondria. The more energy a cell consumes, the more mitochondria it normally has. A heart muscle cell has around 5000 of these energy machines on board. Nerve cells, liver cells and sensory cells are also well equipped. However, the fact thatmitochondria already show the first signs of fatigue in 25-year-oldsis very unfavorable.

The performance of our small power plants is measured in the amount of microbatteries produced, the adenosine triphosphate (ATP) . Weighed in kilograms, the mitochondria produce about as much ATP every day as we weigh to keep all life and metabolic processes running.

At rest, mind you. When we exercise, it's significantly more. This gigantic energy supply system unfortunately tends to weaken quite early - with devastating consequences for our fitness and ability to regenerate.
