To maintain a cool home during the rainy season, ensure proper ventilation by opening windows when it’s not raining. Use light, breathable fabrics for curtains and furniture covers to prevent humidity buildup. Regularly clean and maintain your fans and air conditioning units for optimal performance. Opt for indoor plants that absorb moisture and cool the air. Dehumidifiers can help control dampness, while sealing gaps in doors and windows prevents cold drafts. Avoid using heavy carpets and rugs that trap moisture. Use cool lighting options like LEDs, and regularly check for leaks or water seepage to prevent mold growth.
