With cold wave conditions gripping parts of north and central India, cases of flu-like illnesses and common colds are on the rise. While the common cold is often seen as a minor, universal ailment, growing scientific evidence suggests that men and women experience colds very differently — and biology, not exaggeration, may be the reason.
The popular “man flu” stereotype paints men as dramatic sufferers of minor illnesses. However, studies increasingly show that women often endure more severe and prolonged symptoms, including intense fatigue, body aches and inflammation. Scientists attribute this disparity to hormonal, biological and behavioural differences that shape how the immune system responds to viral infections.
Hormonal Differences Drive Immune Responses
Hormones play a central role in how the body reacts to viruses that cause the common cold, such as rhinoviruses.
- Oestrogen, the primary female hormone, enhances the production of interferons, antiviral proteins that slow viral replication.
- While this helps women clear infections more efficiently, it also triggers stronger inflammatory responses, leading to more pronounced symptoms.
In contrast, testosterone, the dominant male hormone, suppresses pro-inflammatory cytokines. This dampening effect can reduce cold symptoms in men, even though it may leave them more vulnerable to serious infections such as COVID-19.
Biological Factors: Stronger Immunity, Heavier Toll
Women generally mount stronger immune responses to viral infections. Oestrogen boosts immune cell activity and antibody production, helping the body fight off viruses faster. However, this heightened response often comes at a cost.
Women are more likely to experience:
- Severe fatigue
- Muscle and joint pain
- Headaches
- Prolonged recovery periods
Men, on the other hand, often report milder early symptoms like fewer runny noses or sore throats. Some studies suggest men may experience higher fevers, possibly due to testosterone’s effect on the brain’s temperature-regulating centre. These differences also explain why women tend to seek medical attention earlier than men.
Symptom Severity and Duration
Research tracking respiratory infections such as influenza, enterovirus and coronavirus has found that women are nearly twice as likely to report lingering symptoms like exhaustion and body pain beyond the first few days of illness.
Men often experience a shorter, sharper illness — symptoms peak quickly and resolve sooner — while women face a longer battle marked by persistent discomfort.
Behavioural and Reporting Bias
Social conditioning also shapes how illness is perceived and reported.
- Men tend to delay reporting symptoms until they become severe, reinforcing the “man cold” trope.
- Women are more likely to monitor symptoms closely and articulate their discomfort in detail.
While self-reported data shows women logging more symptoms, objective measures such as viral load indicate similar infection rates in both sexes.
Chronic stress — which studies suggest is often higher among women — can further amplify immune responses, prolonging cold symptoms. Men under stress may suppress symptoms, appearing resilient but potentially increasing the risk of complications.
Prevention and Care: One Size Doesn’t Fit All
Understanding these sex-based differences can help tailor better self-care strategies:
- Women may benefit from prioritising rest, hydration and anti-inflammatory support to manage immune overdrive.
- Men may require immune-boosting nutrients like zinc and vitamin D to counter testosterone’s suppressive effects.
The Bottom Line
Colds don’t affect everyone equally. Women often fight longer, tougher battles, while men experience shorter, milder skirmishes. Science challenges the myth of exaggerated male suffering and highlights the need for personalised approaches to health and recovery.
