Is it safe for a toddler to sleep in an 80-degree room?

No, it is generally considered unsafe and highly discouraged for an infant or toddler to sleep in a bedroom where the ambient temperature reaches eighty degrees Fahrenheit or higher. Pediatric safety guidelines and organizations like the American Academy of Pediatrics emphasize that infants and young children have immature thermoregulation systems, making them highly vulnerable to overheating, dehydration, heat exhaustion, and an increased risk of Sudden Infant Death Syndrome (SIDS) when exposed to overly warm sleeping environments. The recommended safe indoor sleeping temperature for babies and toddlers generally ranges between sixty-eight and seventy-two degrees Fahrenheit. You can monitor nursery conditions using a reliable digital room thermometer equipped with a humidity monitor. You can verify a safe sleeping environment when air conditioning or fans maintain a cool, stable room temperature throughout the night.
