What is oxidative stress? Causes, symptoms and treatment

Oxidative stress is not a new concept but is quite unfamiliar to many people. This is a serious disease, it directly affects health that many people easily ignore, leading to a difficult-to-treat condition. So what is oxidative stress? What are the causes, symptoms and treatment? Follow along with Ocany below!

What is oxidative stress?

Oxidative stress (also known as oxidative stress) occurs due to an imbalance between free radicals and antioxidants in the body.

What is Oxidative Stress?

To be more precise, free radicals are oxygen-containing molecules in which the number of electrons is unequal. This is the reason why they easily react with other molecules creating a large chain of chemical reactions inside the body. These reactions are oxidation processes, and they can be beneficial or harmful.

Antioxidants (vitamins A, vitamins C and E or glutathione, etc.) are molecules that readily donate an electron to a free radical without losing its stability. They have the effect of making free radicals highly stable and less prone to reactions that cause oxidation.

So what is oxidative stress? As mentioned above, Oxidative stress occurs due to an imbalance between free radicals and antioxidants. When the number of these free radicals is too high, or the antioxidants are too few, oxidative stress occurs and has the potential to directly affect the body’s DNA and proteins. This problem is not like other diseases, it happens silently and over time will create dangerous diseases.

The negative effects of oxidative stress

When there is the phenomenon of oxidative stress, our health will increasingly decline. At the same time, the body’s organs function less and less. The body’s natural oxidation process has the potential to be disrupted by oxidative stress and this is a sign of an abnormality that we need to be concerned about.

It is easier to imagine, the phenomenon of oxidative stress makes our immunity significantly decline, the organs are increasingly sensitive and extremely vulnerable to attack by bad agents that cannot resistance as an inherent defense mechanism of the body.

The heart is one of the organs that will be most affected by oxidative stress. Atherosclerosis due to hyperlipidemia occurs more often.

In addition, diseases such as diabetes, hypertension, diseases related to the nervous system (common like Alzheimer’s, Parkinson’s), chronic inflammation are also caused by oxidative stress. Not only that, today’s studies also show that oxidative stress increases the risk of cancer and the body’s aging process occurs faster.

Risk factors for oxidative stress

The negative effects of oxidative stress on humans cannot be denied, so what are the risk factors that have led to oxidative stress?

Our bodies always produce free radicals naturally through metabolism or movement – ​​this is a completely normal process. But a diet high in refined sugar, fat, and frequent alcohol use causes increased production of free radicals from within.

In addition, external causes such as the atmosphere, smoke, some pesticides, detergents, radiation and pollution have entered and caused oxidative stress.


Drugs are also one of the causes of oxidative stress

Control and prevent oxidative stress

The passive exposure to agents that cause increased free radicals from the outside is very difficult to avoid. However, we can limit that by increasing the amount of antioxidants in the body. Here are some effective, simple methods that you can apply right at home:

Healthy diet

To supplement antioxidants, reduce the growth of free radicals, supplementation through the daily diet is very effective. In addition to a diet that reduces sugar, fat and harmful substances, we need to add some foods that help increase the production of antioxidants. So what foods can help the body do that?

Berries help increase antioxidant production

  • Berries
  • Prunes
  • Cherry
  • Dark green leafy vegetables (spinach, spinach, lettuce…)
  • Broccoli
  • Carrot
  • Tomato
  • Citrus fruits
  • Olive
  • Fish
  • Nuts
  • Vitamin E
  • Vitamin C
  • Turmeric
  • Green tea
  • Alkaline ionized water
  • Melatonin
  • Onion
  • Garlic
  • Cinnamon

Scientific mode of life

A healthy, scientific lifestyle is also a method to help prevent and minimize the increase of free radicals. You can improve your lifestyle with small things like:

  • Get into the habit of daily exercise: this helps you have a healthy body, prolongs life, increases the production of natural antioxidants in the body, is less affected by oxidative stress, aging, cancer cancer and other chronic diseases.

Regular exercise improves health

  • Limit smoking, avoid places with smoke: Smoking or passive smoking are harmful to the body. Not only the lungs but many organs are affected by smoking.
  • Stay away or be cautious when working with toxic chemicals: pesticides, radiation, detergents, etc. are chemicals that increase free radicals. Please use natural cleaners, minimizing chemical substances.
  • Environmentally conscious: it means a lot to you to have a sense of protecting the environment. Protecting the surrounding environment means protecting yourself from external pollution entering the body.
  • Get enough sleep: sleeping late, staying up late, lack of sleep is always the cause of many medical conditions. The growth of free radicals also cannot avoid this cause. Sleep plays an important role in the body’s recovery. During sleep, your organs will perform the work of elimination and regeneration, if you do not get enough sleep, your body will quickly become exhausted, accelerate the aging process, produce hormones …

Getting enough sleep helps limit the negative effects of oxidative stress

  • Split meals: Continuous overeating contributes to an increase in free radicals, which has been proven in many studies. Eat small portions, eat many meals, and limit fatty foods.

Exposure to free radicals is something we cannot completely avoid but can be minimized with simple everyday measures.

Thus, the article has informed you about the concept of oxidative stress, this is a phenomenon that we cannot see but they are still happening and directly affect the human body. Factors that cause increased free radicals seem simple but extremely harmful to us every day. It is our job to add foods rich in antioxidants and lead a healthy lifestyle to minimize the effects of oxidative stress.
