What lifestyle habits cause oxidative stress?

I have written about how oxidative stress causes various diseases, but this time I would like to talk about what causes oxidative stress in the first place.

There are many causes of oxidative stress in our daily lives. In our daily lives, we may be increasing oxidative stress in our bodies without even realizing it.

If that's the case, it's frightening, isn't it?

Let's take a look at some of the things that can cause oxidative stress.


Are you concerned about sunburn? 

Sunscreen, parasols, hats, etc. Sunburn is a big enemy for those who want to whiten their skin.

So, why does sunburn occur? Sunlight contains ultraviolet rays, and when the ultraviolet rays hit the skin, active oxygen is generated at that point, resulting in oxidative stress. There are three types of ultraviolet rays, two of which are harmful to the human body, and the human body generates reactive oxygen species in an attempt to protect itself from these harmful rays.

Reactive oxygen species (ROS) are responsible for destroying bacteria that enter the body, so we generate ROS to defend ourselves, but when there is too much of them, they cause inflammation in the skin.

If you stay outside for a long time in the summer, your skin will turn red and in severe cases, blister. That's inflammation. Sunburn is the inflammation of the skin caused by reactive oxygen species.
Since reactive oxygen species (ROS) cause the body to rust, sunburn can be said to be one of those rusts. Sunburn also causes pigmentation, or stains. In other words, a sunburn can be thought of as the part of the body exposed to the sun being rusted by active oxygen.
The world is full of causes of oxidative stress, just as the sunlight we are exposed to on a daily basis is related to oxidative stress. There are so many causes of oxidative stress that it would be impossible to list them all.

Here is a list of things to avoid in order to escape oxidative stress.
Items to avoid
・Ultraviolet rays
・Exhaust fumes
・Mental stress in the broad sense
・Radiation
・Tobacco
・Excessive alcohol consumption
They all sound bad for you, don't they?

Yes, they actually increase oxidative stress and have a negative impact on the body. It is best to avoid these things as much as possible.

Next, you need to improve your diet.
Avoid overeating and try to eat more vegetables. If you eat too much sugar in your diet, your body's energy-producing mitochondria will slack off and use only sugar, which is easy to turn into energy, and not oxygen, and the excess oxygen will become reactive oxygen species, resulting in an increase in reactive oxygen species in your body.

The result is an increase in the amount of reactive oxygen species in the body.
Exercise is also important.

Moderate exercise and preventing metabolic syndrome can help lower oxidative stress. There is no need for strenuous exercise like jogging or running. A walk is enough, say 2km or 3km a day. Even light physical activity like that will lower your overall oxidative stress.

Taking supplements to lower oxidative stress is also an effective way.
To lower oxidative stress, avoid things that increase oxidative stress. Exercise. Improve your diet. However, it may be difficult for you to do so in your daily life.
Last but not least, as scientific research progresses, we are gradually learning more and more about why we age. Aging does not start immediately, but is a daily process. We need to continue our daily lifestyle and diet to lower oxidative stress. Many researchers believe that if we continue to do this every day, our life expectancy will probably increase to about 120 years.

It would be nice if we could control oxidative stress well in order to stay healthy for 120 long years.
