The influence of fragrances on human psychophysiological activity has been known for a long time, and fragrances have been used for thousands of years to deliver a variety of benefits, especially for physical and psychological well-being. Perfumes, cleaning products, and anything with fragrance can contain volatile organic compounds (VOCs) which can be irritating and disruptive to our airways and have other negative health effects. Inhaling fragrances means breathing in particles small enough to cross the lining of our blood vessels and enter our bloodstream. While the impact of these chemical combinations is still being studied, some people may be at higher risk of adverse reactions. Multiple sources suggest that perfumes can cause high blood pressure, and there is some scientific evidence to support this claim.

Grapefruit essential oil increases diastolic blood pressure
While perfumes and strong fragrances are not direct causes of high blood pressure, some people have reported experiencing a spike in blood pressure when exposed to certain scents. This is not uncommon, as different individuals can have varying reactions to aromatic compounds.
Grapefruit essential oil, for example, has been found to increase diastolic blood pressure when inhaled. This was observed in two studies, wherein healthy male participants were exposed to fragrance stimulation of grapefruit essential oil for 10 minutes, and their blood pressure, heart rate, and muscle sympathetic nerve activity (MSNA) were measured. The results indicated a significant increase in diastolic blood pressure during fragrance inhalation, while the other variables remained largely unchanged.
The increase in diastolic blood pressure was positively correlated with MSNA, suggesting a link between fragrance inhalation and changes in nerve activity. This correlation was further supported by the linear relationship between changes in diastolic blood pressure and MSNA burst frequency during the last 5 minutes of fragrance inhalation.
Additionally, the plasma cortisol concentration, a stress hormone, decreased significantly at the 10-minute mark of fragrance inhalation, indicating that the changes in blood pressure were associated with changes in nerve activity, even in the presence of reduced stress levels.
These findings highlight the impact of fragrance inhalation on blood pressure and the potential involvement of sympathetic nerve activity. Understanding these relationships can help guide the use of fragrances in aromatherapy and perfumery, ensuring safe and effective applications.

Perfumes contain volatile organic compounds (VOCs)
The health effects of VOC exposure can vary depending on the specific compounds and the duration of exposure. Some people may experience an increase in blood pressure when exposed to perfumes or other strong smells containing VOCs. This is due to the compounds stimulating nerve receptors in the nose, which send signals to the brain that can affect blood pressure. However, it is important to note that not everyone will experience the same reactions, and increased blood pressure is considered an unusual symptom.
To minimize the potential health risks associated with VOC exposure, it is recommended to reduce the use of strongly scented products, including perfumes, and to avoid spaces with poor ventilation where VOC concentrations may be higher. Additionally, individuals can identify specific perfumes or scents that trigger their symptoms and avoid those particular aromas.
While the connection between perfume and high blood pressure is not widely recognized, some individuals have shared their experiences of high blood pressure and headaches after using perfumes or being exposed to strong scents. In one instance, a person's blood pressure rose to 190/100, which they attributed to their new perfume purchases. They described experiencing a pounding head and neck pain shortly after spraying the perfume.
In summary, perfumes do contain volatile organic compounds (VOCs) that can have negative health effects, including potential links to high blood pressure in certain individuals. However, the specific compounds and duration of exposure play a role in the health outcomes, and not everyone will experience the same reactions. It is advisable to limit exposure to VOCs and take precautionary measures to identify and avoid specific triggers.

Fragrances affect brain function
While there is limited scientific research on the direct impact of fragrances on high blood pressure, studies have shown that fragrances can influence brain function. Fragrances or perfumes are a combination of aromatic compounds that create a specific and distinctive odour.
The sense of smell is closely tied to emotions and memories, and fragrances can have a powerful impact on mood and behaviour. Fragrances can influence the levels of neurotransmitters in the brain, such as dopamine and serotonin. For example, the scent of vanilla has been shown to increase levels of dopamine, which is associated with feelings of pleasure and reward. This could explain the popularity of scented products such as candles and potpourri.
The olfactory bulb, located at the front of the brain, plays a crucial role in processing smells. It sends signals to other areas of the brain, including the limbic system, which is involved in emotion and memory. This connection between smell and memory is well-established in neuroscience, and even in the womb, a fetus's sense of smell is fully developed.
The impact of fragrances on the brain is of particular interest to neuromarketing, as it can influence consumer behaviour and decision-making. Techniques such as baking cookies or using scented candles can create a sense of homeliness for potential homebuyers. Additionally, fragrances can have different effects depending on the context and environment. For instance, the scent of lemon may be invigorating in a spa but unpleasant in a hospital setting.
Furthermore, the inhalation of fragrances can lead to immediate changes in various physiological parameters, including blood pressure, muscle tension, pupil dilation, skin temperature, and pulse rate. While fragrances may not directly cause high blood pressure, they can influence these physiological aspects, and for some individuals, certain fragrances or perfumes may trigger a rise in blood pressure.

Aromatherapy can help manage hypertension
Aromatherapy is a popular alternative treatment for hypertension, but does it work? While there is some evidence that essential oils can help manage high blood pressure, the research is limited and ongoing.
Essential oils have been used for centuries to treat various physical and mental ailments. In recent years, they have become a popular natural remedy for hypertension. Essential oils are believed to enter the bloodstream and interact with medications. However, it is important to note that essential oils should not be used as a replacement for prescribed hypertension medication.
Several essential oils have been found to have therapeutic benefits for hypertension. For example, lavender oil has been shown to reduce heart rate and blood pressure, while increasing relaxation waves in the brain. Similarly, marjoram oil has been used in traditional Moroccan medicine to treat hypertension and has been found to reduce myocardial oxidative stress, which can lead to heart failure.
Other essential oils, such as neroli, ylang-ylang, and valerian, have also been found to reduce stress and blood pressure in people with hypertension. A 2017 study found that ylang-ylang had a sedative effect that significantly decreased blood pressure. Rose oil has also been found to have calming effects, reducing blood pressure, heart rate, and breathing rate when applied to the skin.
While the evidence for the benefits of aromatherapy in managing hypertension is promising, it is not conclusive. It is always recommended to consult a doctor before using essential oils, especially if you are already taking medication, as certain oils can interact with your prescriptions.

Perfumes can cause allergic or inflammatory responses
Perfumes can contain volatile organic compounds (VOCs), which can irritate and disrupt our airways, causing allergic or inflammatory responses. These responses can include itchy and watery eyes, congestion, a runny nose, throat irritation, coughing, or wheezing. People with allergies, asthma, or pre-existing conditions like COPD should avoid highly fragranced environments.
Perfumes and fragrances can also contain aromatic compounds, which can cause a rise in blood pressure for some people. This is a rare reaction, but it has been observed in patients who react to aromatic compounds in food.
The inhalation of fragrances has been shown to affect brain function, as fragrance compounds can cross the blood-brain barrier and interact with receptors in the central nervous system. This can lead to immediate changes in physiological parameters such as blood pressure, muscle tension, pupil dilation, skin temperature, pulse rate, and brain activity.
Natural scents, including essential oils and natural perfumes, have been found to have a positive impact on hypertension. They can promote relaxation and reduce stress, which can help in controlling high blood pressure. However, it is important to note that essential oils can also cause an increase in diastolic blood pressure, as seen in a study where healthy men were exposed to fragrance stimulation of grapefruit essential oil.
Overall, while perfumes can cause allergic or inflammatory responses, their impact on blood pressure is complex and may depend on individual factors and the specific type of scent or fragrance.
