Why you should avoid wearing strong smelling lotion in a train

Navigating public transportation requires more than just a valid ticket and knowledge of the route; it demands a high level of spatial and sensory awareness. While we often focus on physical space—keeping our bags out of the way or offering seats to those in need—scent is an invisible yet powerful factor that significantly impacts the commuting experience. In the confined, often recycled air of a train carriage, a personal choice like applying a heavily scented lotion can transform from a self-care ritual into a major public nuisance. This article explores why 'olfactory etiquette' is a critical component of modern commuting, the physiological effects of strong scents on fellow passengers, and how being mindful of your fragrance profile contributes to a more inclusive and comfortable environment for everyone.
The unique environment of a train carriage creates a sensory pressure cooker. Unlike outdoor spaces where breezes quickly dissipate odors, trains are enclosed systems. Modern HVAC systems are designed for temperature control rather than rapid air purification, meaning that once a potent scent is introduced, it tends to linger and circulate within the car for the duration of the journey. For passengers trapped in close proximity during rush hour, there is no escape from the 'scent cloud' that travels with an individual wearing heavy lotion. This forced intimacy makes scent a shared public experience rather than a private preference.
Beyond simple preference, strong fragrances pose genuine health risks for many individuals. Thousands of people suffer from Multiple Chemical Sensitivity (MCS), asthma, or chronic migraines, all of which can be triggered by the synthetic compounds found in perfumes and scented lotions. What might seem like a 'pleasant floral scent' to one person can cause another to experience respiratory distress, intense nausea, or a debilitating headache. In a public transport setting, causing physical discomfort to others is a significant breach of social etiquette. By choosing fragrance-free or lightly scented products, you are directly contributing to the physical safety of your fellow travelers.
Cultural norms regarding personal space and scent vary globally, but the trend in dense urban centers is increasingly moving toward 'scent-free' public zones. In countries like Japan, there is a specific term, 'smell harassment' (sumehara), which describes the discomfort caused to others by strong odors, including perfumes and body products. Even in Western cultures, the workplace and public transport are becoming more sensitive to the sensory needs of a diverse population. Wearing a strong lotion in a crowded train can be perceived as an act of inconsideration, signaling a lack of awareness regarding the shared nature of the space.
The science of scent and psychology also plays a role in how your lotion is perceived. Scents are deeply linked to the limbic system, the part of the brain that handles emotions and memories. Because of this, a scent that you find comforting might be deeply unpleasant or even triggering for someone else based on their past experiences. Furthermore, in a high-stress environment like a morning commute, overpowering sensory input—whether it's loud music or a strong smell—increases the overall stress levels of everyone in the vicinity. Keeping your scent profile neutral helps maintain a calm, professional atmosphere.
Practicality is another reason to save the scented lotions for after your commute. Lotions, especially those with high oil content or heavy fragrances, can transfer onto shared surfaces like handrails, seats, and poles. This leaves a sticky or slippery residue that is unpleasant for the next passenger and can even cause the scent to 'haunt' the train car long after you have disembarked. Applying lotion once you reach your destination or using a fast-absorbing, unscented variety ensures that you leave the train exactly as you found it—clean and accessible for the next person.
To be a more conscientious commuter, consider auditing your morning routine. Look for products labeled 'fragrance-free' or 'hypoallergenic,' which are designed to have a minimal olfactory footprint. If you absolutely love a specific scented product, consider using it as a reward once you arrive at your office or home. Small changes in our personal habits can lead to a massive improvement in the quality of public life. Remember, the goal of public etiquette is to minimize our negative impact on others; by keeping your scent to yourself, you are showing respect for the diverse needs and health of your community.
