Loughborough professor proposes yogurt on windows as a cheap home‑cooling hack

Professor Ben Roberts of Loughborough University explored a novel cooling technique. He found that smearing plain yogurt on exterior windows reduces heat gain. The yogurt's white surface reflects sunlight, lowering indoor temperatures. Experiments showed measurable cooling benefits in test rooms. The method uses a common household item and requires no electricity. Roberts cautioned that the approach works best in specific climate conditions. The finding offers a low‑cost alternative for homeowners seeking energy savings. Further research will assess durability and long‑term effectiveness.
