Do bubbles keep bath warm

Bubbles in a bath can help retain heat to some extent by creating a layer of insulation on the water's surface. This insulation slows down heat loss due to evaporation, which can help keep the bath warm for a longer period. However, the overall effect may be minimal compared to other factors such as the initial water temperature and room conditions. To maintain warmth, it's best to add hot water periodically or use a bath cover.
