Doctors warn: scented candles can cause allergies and respiratory problems.

According to ТСН: For many, candles are associated with holidays. However, in addition to the pleasant aroma that fills the air during their burning, candles can hide dangerous health risks. Experts point to the possibility of serious respiratory problems and even fires.

Risks of scented candles

Doctor Neil Patel from the 'LloydsPharmacy' network emphasizes that scented candles can trigger allergies due to harmful chemicals in their composition. Many candles contain artificial fragrances, dyes, and other additives that release toxic compounds into the air when burned.

“These chemicals can irritate the respiratory system, leading to symptoms such as coughing, sneezing, or nasal congestion,”

— explained the doctor, urging people who feel the negative effects of these compounds to refrain from using candles.

Tips for safe candle use

Patel advises those with sensitive eyes to choose unscented candles or avoid them altogether. This is confirmed by an article in the 'Annals of Medicine and Surgery' which informs about the dangerous gases that are released during the burning of scented candles. The research found carcinogens in their vapors, including naphthalene and pyrene, which are formed from the combustion of wax, dyes, and fragrances.

Among the common symptoms described by people who have been exposed to scented candles are:

• dizziness;
• headache;
• irritation of the mucous membranes;
• breathing problems;
• tearing;
• sneezing;
• nasal congestion;
• tightness in the chest.

Research has also shown that burning candles increases the levels of formaldehyde, $CO_2$, and other volatile compounds in the air. Dyes in wax are linked to an increased risk of bladder cancer, especially with prolonged use of candles in poorly ventilated spaces. Experts recommend choosing products made from natural beeswax and essential oils instead of synthetic ones.

Pulmonologist Rene Dixon notes that candles are not immediately dangerous; however, their use may be related to oncological diseases due to the accumulation of toxins in the blood. People with bladder cancer and chronic lung diseases should completely refrain from candles.

Safe practices while using candles

Experts recommend following a few simple rules for the safe use of candles:

• use high-quality candles;
• light the candle in a well-ventilated room, away from flammable items;
• do not let the candle burn for more than four hours;
• never leave a candle unattended and do not light it if you plan to fall asleep;
• instead of blowing out the candle, use a snuffer;
• do not attempt to touch or move the candle until it has cooled down.

It is also worth noting that safe candle use is not only about health but also about creating a pleasant atmosphere. The right approach will allow you to enjoy a romantic mood without unnecessary health risks.
