SINGAPORE, 27 March 2026 — In Singapore, where warm weather
and a walkable urban environment encourage year-round activity, more working
adults who recently started regular exercise are reporting knee discomfort.
While many
attribute such pain to gradual “wear and tear” of cartilage, emerging research
points to more complex causes. In 2023, the Van Andel Institute published a
review examining how stress factors affect cartilage cells. Aging leads to
cellular damage and reduced repair ability, particularly in articular
chondrocytes, the main cells maintaining joint cartilage. These cells face
stressors including mechanical overload, oxidative stress, DNA damage, protein
balance disruptions, and metabolic imbalances.
Oxidative stress
plays a key role. When reactive oxygen species (ROS) accumulate beyond the
body’s ability to neutralize them, they damage cells. In cartilage, where
regeneration is limited, this can accelerate breakdown of chondrocytes and loss
of proteoglycans, which act like springs to absorb shocks, contributing to
joint discomfort.
Although ROS are
naturally produced and partially regulated by the body’s antioxidant systems,
aging, stress, and poor lifestyle habits can disrupt this balance, allowing
oxidative damage to accumulate.
Experts recommend
a balanced approach to joint care: regular low-impact exercise, a diet rich in
antioxidants, and effective stress management. Functional supplements with
antioxidant properties can complement these measures. Studies show that beeswax
alcohols from Cuban beeswax increases total antioxidant status (TAS), reduces
lipid and protein oxidation markers, and helps relieve mild joint stiffness
while maintaining cartilage health.
“Joint health
should be viewed as the result of complex cellular balance, not just aging,”
says a healthcare professional. “Managing oxidative stress daily is vital for
Singaporeans who wish to stay active and mobile for years.”
