Being in a tropical country means living with higher humidity levels, especially on warm days. The water-absorbing hydrogel is eight times more efficient than previously known drying agents, and can quickly reduce the relative humidity of a small room from 80 to 60 per cent in a matter of minutes. After taking in water from the environment, the hydrogel becomes opaque and is able to block infrared light by 50 per cent. This means that if coated on windows, the hydrogel can reduce the relative humidity of a room while also blocking off the heat from natural sunlight.
