What are the factors that increase reactive oxygen species (ROS), the source of oxidative stress?

There are many factors that increase reactive oxygen species (ROS), the source of oxidative stress, all around us.

For example, ultraviolet rays, smoking, large amounts of alcohol, electromagnetic waves, radiation, environmental hormones, pesticides, agricultural chemicals, stress, excessive muscular work, car exhaust, and so on, just to name a few.

 

Reactive oxygen species (ROS) are formed from a portion of the oxygen that we take into our bodies through respiration.  Reactive oxygen species are highly reactive substances, which means that they are easily influenced or transformed into other substances by some stimuli.
These highly reactive oxygen species are very effective as weapons to defend the body against foreign substances such as bacteria and viruses, but they also have the side effect of damaging healthy cells. However, they also have the side effect of damaging healthy cells, just like the rusting of metal.

When cells in the body are damaged by reactive oxygen species, it becomes difficult for those cells to maintain normal biological reactions. This is called "rusting" of the body. When this happens to various organs, it is thought to cause various dysfunctions and diseases such as diabetes, hyperlipidemia, and impaired liver function.
Many lifestyle-related diseases are thought to be caused by this "rusting of the body", and it is now said that more than 150 different diseases may be related to oxidation caused by reactive oxygen species, or rusting of the body.

For a long and healthy life, it would be better if we could eliminate the external factors that generate reactive oxygen species, the source of body rust and oxidation, but since these factors are all closely related to our lives, it is very impossible to eliminate all of them.
However, it is possible to "stay away from the factors as much as possible" by improving your lifestyle. At the same time, it is not impossible to weaken the activity of excess reactive oxygen species if they have been produced, or to reduce the amount of reactive oxygen species generated unnecessarily in the first place.

If this can be achieved, it may help to prevent lifestyle-related diseases and slow down the aging process.
