Winter illnesses have a way of colliding with everyday life. You wake up congested, aching, and already behind schedule.
Rest feels like a luxury, so many people reach for over-the-counter remedies to push through work, exercise, and obligations as if nothing is wrong.
But doctors warn that this habit, especially during a severe flu season, may come with risks that are easy to overlook.
Flu season pressure
This winter has brought unusually high flu activity across parts of Europe, putting strain on healthcare systems and encouraging people to self-manage symptoms at home.

As a result, common medications such as painkillers and nasal decongestants are being used more frequently and often without medical guidance.
Spanish cardiologist Aurelio Rojas has raised concerns about how certain widely used medicines affect the cardiovascular system, particularly when taken repeatedly or combined with physical exertion.
According to Rojas, many people assume that non-prescription drugs are harmless simply because they are easy to access.
In reality, some of these medications influence blood pressure, heart rate, and fluid balance, which can place additional stress on the heart when the body is already weakened by infection.

When relief becomes strain
Several cold and flu treatments work by constricting blood vessels to reduce congestion or inflammation.
While effective for symptom relief, this mechanism can also increase blood pressure and accelerate the heart rate.
Painkillers commonly used for fever and muscle aches may interfere with mineral absorption or hydration levels, particularly when taken over several days.
For people with underlying heart conditions, high blood pressure, or those who continue intense physical activity while ill, these effects can become more pronounced.

Doctors emphasize that problems rarely arise from a single dose. Risk increases when medications are used continuously, combined with exercise, or taken without regard for how the body is responding.
Knowing when to slow down
Medical experts advise viewing medication as temporary support rather than a tool to override illness.
The heart works harder during infection, and forcing the body to perform at normal capacity can prolong recovery or trigger complications.
Warning signs that should not be ignored include:

- unusual fatigue or muscle cramping
Health professionals recommend reducing physical strain during illness and consulting a doctor if symptoms persist or if medication is needed for extended periods.
During flu season, allowing time for proper recovery may be one of the most effective ways to protect both short-term health and long-term heart function.
