Oxidative stress

To protect itself from oxygen species, the organism confronts them with antioxidants. These cause a break in radical chain reactions, since the antioxidants themselves donate an electron, but do not react any further and break down the oxygen species enzymatically.

Oxidative stress occurs when the balance between oxidative and reductive reactions is disturbed and the oxidative processes gain the upper hand. This causes damage to vital cell membranes, enzymes and protein structures (such as our DNA, the genetic material in the cell). Last but not least, this also leads to accelerated cell aging. For example, people with Hutchinson-Gilford syndrome (premature aging) have no protective mechanisms against free radicals. 

The attack of free radicals on unsaturated fatty acids in our body contributes to the development of arteriosclerosis. Likewise, oxidative stress is suspected to be involved in the development of cancer, diseases of the immune system and also neurodegenerative diseases.

But also autoimmune diseases and infections with latent subliminal inflammations are among them. In addition, environmental factors such as UV radiation or blue light (emitted by screens, for example) are also suspected as causative factors. Exhaust fumes and fine dust and especially environmental toxins or chemicals such as pesticides, aggressive solvents or heavy metals also play a major role.
