No AC required: India’s 3000-year-old cooling technique can reduce heat up to 50% in your home naturally, says study
Ancient Indian communities utilized terracotta's porous nature for cooling, a practice dating back over 3,000 years to the Indus Valley Civilization. This natural evaporation process, similar to human perspiration, draws heat away. Modern architecture is reviving this by integrating terracotta pots into filler slabs, creating insulating air gaps that significantly reduce indoor temperatures and offer year-round climate balance.
Why Your Clothes Lose Color So Fast Might Have Nothing To Do With Detergent
Washing clothes in hot water significantly accelerates color fading and fabric wear, according to scientific research. Higher temperatures, especially above 40°C, increase dye desorption.
