What is one method to reduce the risk of hyperthermia in infants?

Utilizing temperature-controlled blanket warmers is an effective method to reduce the risk of hyperthermia in infants. These devices are designed to maintain a consistent and safe temperature, ensuring that the infant does not experience fluctuations that could lead to overheating. By carefully regulating the warmth provided, these warmers help maintain the optimal body temperature of infants, particularly those who are vulnerable, such as premature or low-birth-weight babies. The controlled nature of these warmers provides a safe environment, minimizing the risks associated with temperature extremes, which is crucial for infant care.

The other options pose risks that could contribute to hyperthermia. For instance, microwave-warmed blankets may not heat evenly, leading to hot spots that could dangerously overheat sections of the blanket. Hot water bottles can also create uneven heating and might pose a risk of burns. Overheating surfaces of the incubator is similarly unsafe, as it increases the environment's temperature beyond what is safe for the infant. Therefore, the use of temperature-controlled blanket warmers is the most reliable and safest approach to prevent hyperthermia.
