Oxidative stress is caused when there’s an imbalance between free radicals and anxioxidants in the body. Free radicals are molecules containing oxygen that contain an uneven number of electrons. This allows them to react with other molecules easily. When this happens, it can cause large chain chemical reactions in your body. This creates oxidation which can be either beneficial or harmful.

We consume antioxidants as they donate electrons to free radicals without causing instability. When they’re able to stabalize using antioxidants, they become less reactive.

Oxidative Stress On The Body

When functioning properly, free radicals fight off pathogens. Pathogens lead to infections, so this is crucially important. When more free radicals are present in your body than antioxidants, the free radicals start to damage your DNA, fatty tissue and proteins. This damage leads to numerous diseases over time, such as:

  • Aging
  • Alzheimer’s
  • Atherosclerosis (the hardening of blood vessels)
  • Cancer
  • Diabetes
  • High Blood Pressure (hypertension)
  • Heart Disease
  • Inflammatory Conditions
  • Parkinson’s Disease

The Risks Of Oxidative Stress

Exercise and inflammation are everyday processes that produce free radicals naturally. This is a normal part of keeping your body healthy.

The environment also exposes you to free radicals such as:

Managing And Preventing Oxidative Stress With Healthy Choices

Being completely free of free radical exposure and oxidative stress isn’t possible. You can, however, take steps to minimize the effects of oxidative stress on your body. The easiest way to do this is to increase the levels of antioxidants in your body while decreasing the free radicals.

The first method of preventing oxidative stress is reducing the number of free radicals. Drinking water from the tap or plastic bottled water makes you ingest enormous amounts of unnecessary free radicals into your body. The safest thing to do is to get a water filter from Rebbson.

The next method to prevent oxidative stress is to obtain enough antioxidants in your diet.

You need to eat multiple servings every day of a variety of fruits and vegetables. This gives your body what it needs to produce antioxidants. Great fruits and vegetables include:

Studies show that blueberries, blackberries, and raspberries have the highest antioxidant activity of commonly consumed fruits.

Broccoli’s antioxidant properties have been shown to help autism, cancer, diabetes, digestion, eye and heart health.


Image result for carrots

Carrots contain carotene, an antioxidant that decreases your risk of getting cancer.


Image result for cherries

Cherries contain anthocyanin, melatonin, phenols and quercetin. Anthocyanin is good for the heart and cherries also inhibit plaque formation.

Citrus fruits

Other Lifestyle Choices To Prevent/Reduce Oxidative Stress

Avoid Secondhand Smoke

It’s not enough to avoid smoking, you must also avoid secondhand smoke. If someone you live with smokes, tell them to smoke outside so you don’t get oxidative stress from the secondhand smoke. If they won’t stop, consider living elsewhere.

Avoid Bottled Water

The plastic from water bottles go into your water, skyrocketing your oxidative stress levels. To combat this, buy a non-plastic container to hold your water and use a water filter to fill it up. At Rebbson, we have a range of water filters and hydrogen water filters to suit your needs and budget.

Don’t Overeat

Overeating or constant eating keeps your body in a state of oxidative stress more regularly than if you eat appropriate portions at appropriately spaced intervals.

Exercise Regularly

When you exercise regularly, you’ll have naturally higher antioxidant levels and less damage caused by oxidative stress. This will lead to a longer life, less detrimental effects from ageing, and less risk of cancer and disease.

Sleep Regularly

It’s crucial to sleep well every night to maintain balance in your body. When your body’s balanced, your brain, hormones and a variety of other crucial functions work optimally.


Antioxidants and free radicals are an important part of your body’s healthy functioning. While that is the case, oxidative stress occurs when these components are out of balance. Oxidative stress causes damage to your tissues, which leads to mild to severe health problems over time.

Exposure to free radicals are inevitable. There’s nothing you can do to completely avoid this exposure, but the use of a water filter, diet choices, exercise and your environment can help to keep your body in balance, preventing damage to your body.
