Profumo sul collo: il rischio per la tiroide spiegato dall’infettivologo Bassetti
A seemingly harmless daily habit – applying perfume to the neck – could potentially pose a health risk. According to Italian infectious disease specialist Matteo Bassetti, this common practice may interfere with the proper functioning of the thyroid.
The Potential Link Between Perfume and Thyroid Health
While caution has long been advised regarding perfume use – such as avoiding application before sun exposure to prevent allergic reactions – a new concern has emerged. Matteo Bassetti recently highlighted the risks associated with perfume exposure and its potential impact on the thyroid via his social media accounts.
Why the Neck is a Sensitive Area
“Where do we spray perfume? Generally, even I spray it on my neck,” explains Bassetti, Director of the Infectious Diseases Clinic at San Martino Hospital in Genoa. He then poses the question to his followers: “Is it healthy to apply it there? It doesn’t seem so.” Applying perfume to the neck, he suggests, could be more harmful than it appears, as this area is located directly above the thyroid.
The thyroid is a vital organ responsible for regulating metabolism, energy levels, body temperature, and hormonal balance. Furthermore, the skin on the neck is thin, sensitive, and lacks a significant number of sebaceous glands, offering less protection.
The Role of Endocrine Disruptors
Bassetti cites a study published in Environmental Health Insights that revealed the presence of endocrine disruptors in scented products, including synthetic musks and phthalate derivatives. These substances, absorbed through the skin or inhaled, can potentially disrupt hormonal function over time. He recommends applying perfume to areas like the wrists, inner elbow, or the nape of the neck – areas less directly exposed – or to clothing and hair. Bassetti also suggests choosing alcohol-free products.
What the Research Suggests
Researchers who authored the study cited by Bassetti explain that many personal fragrance products contain endocrine disruptors, particularly synthetic musks and phthalate derivatives. Continuous exposure to these substances may pose a risk to hormonal function, especially over the long term. The concern isn’t a single application, but rather the cumulative effect of consistent exposure, potentially compounded by other environmental factors like phthalates found in water or household items.

Additional Risks to Consider
Beyond potential thyroid effects, continuous use of unsuitable perfumes can also lead to phototoxicity – reactions triggered by sun exposure after contact with potentially allergenic substances. This can manifest as skin reactions, including persistent spots and inflammation, though the neck’s fragility makes it particularly vulnerable.
The Impact of Alcohol and Essential Oils
Both Bassetti and other medical professionals recommend choosing alcohol-free perfumes, as alcohol can dry and sensitize the skin, especially with repeated application to the same area. Certain essential oils, such as bergamot and bitter orange, are also known to be photosensitizing and should be used with caution.
Understanding the Thyroid’s Function
The thyroid, located at the base of the neck, is a butterfly-shaped gland that secretes hormones – T3 and T4 – crucial for metabolism. These hormones directly influence how the body uses calories and play a role in cardiovascular function and fetal development during pregnancy. According to Isabella Gallerani of MioDottore, components like phthalates found in perfumes have been associated with negative health effects, including hormonal imbalances, though further research is needed to confirm this correlation.
Frequently Asked Questions
What is an endocrine disruptor?
Endocrine disruptors are substances found in scented products, like synthetic musks and phthalate derivatives, that can alter hormonal function when absorbed through the skin or inhaled.
Where should I apply perfume to minimize risk?
Bassetti recommends applying perfume to areas like the wrists, inner elbow, or the nape of the neck, as well as to clothing or hair, rather than directly to the neck.
What type of perfume should I choose?
Both Matteo Bassetti and other doctors suggest choosing alcohol-free perfumes to avoid skin dryness and sensitivity.
Given these emerging concerns, how might individuals adjust their perfume habits to prioritize long-term health and well-being?
