Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that burning scented paraffin candles indoors harms human health?

Partly. Several sources show that burning scented paraffin candles indoors releases VOCs, fine particles and carcinogenic compounds, and one clinical source says the amounts are tiny and evidence is insufficient to call them dangerous to health. The evidence covers emissions and partial health concerns but does not fully settle whether indoor scented paraffin candle burning harms human health.
