Winter is not coming now. It is here. And, as always, it also brings with it some disease. That's why incorporating winter wellness strategies into your workplace employee wellness programs is important to protect productivity.
According to surveillance data, as the flu season in South Africa continues to peak in winter, the detection rate of cases tested will reach more than 10% in 2025.
Influenza was responsible for about 97% of infections last year, underscoring seasonal pressure on immunity.

“Winter doesn't just make us feel uncomfortable,” says Kerry Rudolph, CEO of Ivy Bar.
“It changes how our cells function, how our immune system responds, and even how our mood and energy are regulated.
“Understanding these changes is the first step to staying resilient.”
Research shows that respiratory viruses spread more efficiently in cool, dry air.
With more people indoors, transmission rates increase.
At the same time, less sunlight disrupts circadian rhythms, reduces serotonin and alters melatonin levels.
The result: sluggish mornings, afternoon fatigue, and decreased mental clarity.
Hydration is also affected. Cold weather slows down thirst signals, while indoor heat speeds up fluid loss.
Even mild dehydration can cause headaches, fatigue, and slow recovery.
Circulatory changes increase the load, causing blood vessels to constrict, causing cold hands and feet, muscle stiffness and joint discomfort.

It may be a cliché, but prevention is definitely better than cure.
A wellness expert from The Hiding suggests that the wellness conversation should shift from treatment to prevention, encouraging South Africans and their workplaces to take a proactive approach to health before seasonal challenges begin to impact daily life.
Dr. Seb Morelli says, “Winter wellness isn't about reacting when something goes wrong. It's about creating habits and support systems that help you maintain energy, flexibility, and overall well-being throughout the season.”
He says traditional wellness often overlooks movement as an important pillar of immune function and nervous system regulation.
“True winter health begins proactively before any symptoms appear. The physical aches, pains and stiffness typically caused by cold weather are driven by sedentary habits caused by winter, such as prolonged sitting and inactivity indoors.
“Since the human brain is a highly energy-demanding organ dependent on glucose, it is naturally wired to conserve energy, which often drives us to stay warm and still rather than active.
“However, this forward bending at rest reduces mobility and basal energy while increasing structural stiffness,” says Morelli.

Upskilling your workforce can be key to reducing downtime and increasing productivity.
Morelli explains that movement is one of the most powerful, evidence-based tools for whole-body health, directly enhancing recovery, circulation, joint mobility, and muscle strength.
When the body moves, the increased blood flow efficiently delivers essential oxygen and nutrients to the muscles, optimizing the body's natural healing processes.
In addition, regular, moderate exercise strengthens immune surveillance, allowing the body to recognize and respond to common infections more effectively.
While regular walking is not a complete cure for seasonal bugs, active individuals statistically experience fewer illnesses and recover faster.
Instead of waiting to take action until you feel stiffness, pain or weakness, prioritizing consistent physical activity and investing in preventative strategies today ensures the body functions at its best throughout the season.
Morelli concludes, “Winter wellness isn't just about avoiding seasonal illness; it's about adopting a proactive approach to health that strengthens immunity, maintains energy levels, supports skin health, improves sleep quality, balances hormones and promotes long-term wellness.”
