As the holiday season approaches, scented candles and colorful garlands become indispensable attributes of the New Year's mood. However, these beloved decorations can be harmful to your health. Experts warn of the risks associated with their use, including the toxicity of the materials and the impact on sleep quality.
Candles made from paraffin, a petroleum product, can release toxic chemicals like toluene and benzene. These chemicals can cause headaches, dizziness, and, in the worst cases, serious illnesses, including cancer. Studies show that even unlit candles can release volatile organic compounds (VOCs), although their concentrations are usually safe.
The problem is compounded when burning scented candles: their emissions can far exceed safe limits. For example, strawberry scent causes formaldehyde emissions of 2,098 parts per billion, while the permissible level is up to 400 parts.
Even safer alternatives, like soy or beeswax candles, emit VOCs, especially if they contain artificial fragrances.
Holiday lights, despite their atmospheric nature, can negatively affect sleep quality. Dr. Catherine Hall emphasizes that bright or flickering lights before bedtime reduce levels of melatonin, a hormone that regulates sleep cycles. Blue lights are especially harmful, as they can completely disrupt the circadian rhythm.
The “flicker” mode is also dangerous: it creates unnecessary visual stimulation that excites the brain and makes it difficult to fall asleep. Multi-colored lights further enhance this effect.
How to avoid risks?
- Choose candles made from natural materials, such as soy or beeswax, without fragrances.
- Ventilate the room after using candles.
- In the evening, avoid turning on bright or flickering lights, especially those with blue light.
The New Year's atmosphere is important, but safety and health should always come first.
