Basics of Free Radicals and Oxidative Stress

Basics of Free Radicals and Oxidative Stress

Free Radicals and Oxidative Stress

A free radical is an atom with an unpaired electron floating around. They are formed every time we produce energy. They float around and try to bond to other molecules in healthy cells. When they do this, they release energy that can damage surrounding tissues, organs, joints, damage DNA and RNA strands, and damage the skin. This process is called oxidation.

Free radicals destroy neurons and synapses. They would rather bond with fat cells and as the brain and nerve cells are made up of a lot of fat, particularly the cell membrane which is the most important part of the cell, they can destroy a lot of brain and nerve tissue through oxidation.

Oxidation is basically the same thing as rusting. It’s what you see when you cut an apple in half and watch it turn brown, or like a piece of metal left out in the weather and it rusts. This is basically what happens when free radicals attack our tissues.

To control this, we have antioxidants that help protect us against the negative effects of free radicals. Our body produces antioxidants naturally and we also get them from food and supplements.

Free radicals also promote inflammation.

Some things that increase oxidative stress and increase mitochondrial aging include:

  • Insulin and high glucose environments generate free radicals and promote oxidative stress. 
  • Chronic stress – leads to the over production of free radicals, weakens your immune system, and lowers your insulin sensitivity, among other things. (This is why the meditation, breathe work, grateful log type stuff above is important to implement)
  • Sleep deprivation and circadian mismatches promote all disease. If your body’s biological clocks are misaligned with its circadian rhythms, then you’ll cause more cellular stress and predispose yourself to all types of dysfunctions.
  • Environmental toxins – pesticides, heavy metals, plastics, cleaning products, personal care products can all increase oxidative stress
  • Processed food and overcooked food – increase the amount of free radicals in it

Fasting can help reduce the free radical and oxidative stress load. It is also beneficial for mitochondrial function due to this.

Fish oil, alpha lipoic acid, glutathione, CoQ10, Vitamin E and C, can decrease free radicals and oxidative stress.

So, free radicals will always be produced. You just don’t want too many of them going out of controlling, causing damage

Sleep and Hydration

Sleep and Hydration


Two of the most overlooked, beneficial things you can do for health and performance is getting quality sleep and ensuring you are properly hydrated. They may not be the most fancy things to work on but they are the foundation for everything else.

Too often people come to me and ask all these questions about things they are not even close to being ready for. For example they will come in and ask if we can do a salivary cortisol test because they think they have adrenal fatigue. When I ask some things about their lifestyle, like how well do they sleep, they are getting about 5 hours per night at best. Well we don’t need a test to know why you feel tired and burnt out. Get your sleep and lifestyle in order first and then after you have done that for a long period of time, you may want to invest in some testing. Just because you test something doesn’t give you the solution to your problem. If your results come back and say you are screwed up then you are still going to have to address your sleep, nutrition, and lifestyle choices anyway.

The benefits of sleep are enormous but people don’t realise or want to realise it because they don’t want to change their crappy habits of sitting up all night on Facebook or watching T.V.

Here are some benefits of sleep well:
  • Reduce obesity
  • Improve insulin sensitivity
  • Improve hormone function
  • Improve memory and learning
  • Improve athletic performance including speed and reaction time
  • Decrease body fat levels
  • Decrease inflammation

When it comes to hydration I hear all sorts of ridiculous things like “I wish I could drink more water” When I ask why they can’t, I commonly hear “oh, I don’t like the taste”. So you can drink water but you choose not to. Their faces go blank.

There are many negative things associated with dehydration such as:
  • Decrease in strength and power
  • Problems with cartilage and the inter-vertebral discs
  • Inflammatory issues and chronic pain
  • Digestive issues
  • Compromised immunity
  • Asthma and allergies
  • Fatigue
  • Headaches

Optimal athletic performance cannot be achieved with sub-optimal levels of hydration since all the body's functions depend on adequate fluid levels. Avoiding dehydration will allow you to maintain peak power levels during repeated anaerobic efforts.

Greater hydration will allow you to train harder and longer, and there is evidence that dehydration causes cardiovascular stress as well as deterioration in central nervous system function.

Stop looking for extreme reasons why you aren’t achieving your goals. For 90% of people out there you are looking for an excuse. You have to have your foundation sorted and do it consistently for a long period of time, not for a week or two. It has to be an everyday thing. If you can’t do this, whether you have a gene mutation or some shit like that doesn’t really matter. Sure it may be having an impact but if you’re not sleeping or you are chronically dehydrated then I don’t think it matters. Half the shit that gets asked are things you work on when you have been doing all these things correctly for years. Then when you plateau you can begin to look into more complicated issues to further progress.

Stop looking for a quick fix, work hard, and be consistent with your sleep, hydration, nutrition, and other lifestyle choices.
