Simple cooling tips help Brazilians sleep better in hot weather

Guides aimed at residents of Brazil's hot and humid regions recommend low‑cost habits to improve nighttime comfort. Keeping rooms well‑ventilated by opening windows for cross‑drafts, using fans correctly, and closing curtains during peak heat can lower indoor temperature. Maintaining adequate hydration, wearing light cotton clothes, and following a regular sleep schedule also support better rest. An additional technique involves lightly dampening a sheet or towel; as the water evaporates, it absorbs heat and creates a cooling sensation on the skin, offering relief without air‑conditioning. Eating light meals and avoiding caffeine or alcohol in the evening are further advised. Together, these measures aim to reduce sleep interruptions caused by high nighttime temperatures without requiring expensive equipment.
