As the holiday season approaches, scented candles and colorful garlands become indispensable attributes of the New Year's mood. However, these favorite decorations can harm your health. Experts warn about the risks associated with their use, in particular the toxicity of the materials and the impact on the quality of sleep.
Candles made from paraffin, a product of petroleum refining, can emit toxic substances such as toluene and benzene. These chemicals cause headaches, dizziness and, in the worst cases, serious diseases, including cancer. Studies show that even unlit candles can emit volatile organic compounds (VOCs), although their concentrations are usually safe.
The problem is aggravated when burning scented candles: their emissions may significantly exceed safe limits. For example, strawberry flavoring causes the release of 2,098 parts per billion of formaldehyde, while the acceptable 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 atmosphere, can negatively affect the quality of sleep. Dr. Kathryn Hall points out that bright or flickering lights before bed reduce levels of melatonin, the hormone that regulates sleep cycles. Especially harmful are blue lights, which can completely disrupt the daily rhythm.
The "flicker" mode is also dangerous: it creates excessive visual stimulation, which excites the brain and makes it difficult to fall asleep. Multicolored 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 twinkling garlands, especially with blue light.
New Year's atmosphere is important, but safety and health should always come first.
