You might feel fine. But "fine" and "thriving" are two very different things. Oxidative stress is one of the most common — and most overlooked — drivers of how you feel day to day. Here are five signs your body may be struggling.
1. Constant Fatigue or Low Energy
If you're sleeping enough but still waking up exhausted, oxidative stress could be affecting your cells' ability to produce energy. When free radicals damage mitochondria — the powerhouses of your cells — you end up feeling flat, drained, or lacking motivation no matter how much rest you get.
2. Brain Fog and Poor Focus
The brain is particularly sensitive to oxidative damage. If you're experiencing slower thinking, forgetfulness, or reduced mental clarity, it may be a sign that your antioxidant defences aren't keeping up. Many people chalk this up to stress or age — but it's often something that can be addressed.
3. Premature Ageing (Skin + Body)
Oxidative stress is one of the primary drivers of accelerated ageing. It breaks down collagen, affects skin quality, and contributes to the kind of vitality loss that makes people feel older than their years. If you're noticing your body isn't bouncing back the way it used to, this is worth paying attention to.
4. Frequent Illness or Slow Recovery
Your immune system relies heavily on antioxidants to function well. Weakened antioxidant defences mean your body can struggle to recover and repair — leaving you more susceptible to illness and taking longer to bounce back when you do get sick.
5. Ongoing Inflammation or Aches
Oxidative stress and inflammation go hand in hand. Even people who exercise regularly can experience slower recovery, persistent aches, or a general sense that their body is always slightly inflamed. It's a signal worth taking seriously.
Why These Signs Are Often Ignored
Most people attribute these symptoms to ageing, busyness, or the demands of modern life. And because they come on gradually, it's easy to accept them as normal. They're not. They're your body asking for better support.
What Can You Do About It?
- Improve your diet — focus on antioxidant-rich foods like berries, leafy greens, and colourful vegetables
- Prioritise sleep and stress management
- Maintain regular movement and exercise
- Consider targeted supplements to fill the gaps your diet misses
The Most Important Step: Measure First
The challenge is that you can't feel your antioxidant levels — and you can't improve what you can't measure. A Prysm iO scan takes just 15 seconds, is completely non-invasive, and gives you an actual number that tells you where you stand. From there, you can take action with confidence.
