Oxidative stress: the silent wear and tear inside your body

Oxidative stress, a hidden form of damage occurring within the body, is caused by an excessive buildup of unstable molecules called free radicals. These free radicals are produced as part of the body's normal functions, such as energy production, infection fighting, and repair. However, when there is an imbalance where free radicals overwhelm the body's natural defenses, oxidative stress occurs.

Pharmacist Benjamin Lim explained that a balance between free radicals and antioxidants is essential. While too many free radicals can cause damage, they also play crucial roles in immune function and clearing damaged cells. Lim emphasized the importance of a balanced approach, noting that too little free radical activity can be problematic too.

The damage caused by oxidative stress can accumulate over time, potentially leading to various diseases. This damage may initially impair the mitochondria, the cell's energy-producing structures, which in turn can generate more free radicals, further exacerbating the issue. Chronic oxidative stress has been linked to conditions like high cholesterol, diabetes, immune system decline, and liver dysfunction.

Symptoms of excessive oxidative stress include fatigue, reduced energy, premature aging, slower mental processing, and slower wound healing. To combat these effects, maintaining a healthy balance of free radicals and antioxidants is crucial. This can be achieved through a balanced diet rich in fruits and vegetables, regular exercise, adequate sleep, and managing stress levels.

Antioxidants, produced naturally by the body and also available through supplements like ginkgo biloba, can help neutralize free radicals. Nitric oxide, vital for healthy blood vessels, can also be depleted by oxidative stress, but ginkgo biloba may help preserve its activity. This highlights the importance of a holistic approach to managing oxidative stress, incorporating diet, exercise, and lifestyle modifications.
