SINGAPORE, 27 March 2026 \u2014 In Singapore, where warm weather
\nand a walkable urban environment encourage year-round activity, more working
\nadults who recently started regular exercise are reporting knee discomfort.<\/p>\n
While many
\nattribute such pain to gradual \u201cwear and tear\u201d of cartilage, emerging research
\npoints to more complex causes. In 2023, the Van Andel Institute published a
\nreview examining how stress factors affect cartilage cells. Aging leads to
\ncellular damage and reduced repair ability, particularly in articular
\nchondrocytes, the main cells maintaining joint cartilage. These cells face
\nstressors including mechanical overload, oxidative stress, DNA damage, protein
\nbalance disruptions, and metabolic imbalances.<\/p>\n
Oxidative stress
\nplays a key role. When reactive oxygen species (ROS) accumulate beyond the
\nbody\u2019s ability to neutralize them, they damage cells. In cartilage, where
\nregeneration is limited, this can accelerate breakdown of chondrocytes and loss
\nof proteoglycans, which act like springs to absorb shocks, contributing to
\njoint discomfort.<\/p>\n
Although ROS are
\nnaturally produced and partially regulated by the body\u2019s antioxidant systems,
\naging, stress, and poor lifestyle habits can disrupt this balance, allowing
\noxidative damage to accumulate.<\/p>\n
Experts recommend
\na balanced approach to joint care: regular low-impact exercise, a diet rich in
\nantioxidants, and effective stress management. Functional supplements with
\nantioxidant properties can complement these measures. Studies show that beeswax
\nalcohols from Cuban beeswax increases total antioxidant status (TAS), reduces
\nlipid and protein oxidation markers, and helps relieve mild joint stiffness
\nwhile maintaining cartilage health.<\/p>\n
\u201cJoint health
\nshould be viewed as the result of complex cellular balance, not just aging,\u201d
\nsays a healthcare professional. \u201cManaging oxidative stress daily is vital for
\nSingaporeans who wish to stay active and mobile for years.\u201d<\/p>\n
