Thermal regulation plays a central role in sleep vulnerability that frequently goes overlooked. Public health guidance issued during the June 2026 heatwaves across Europe and North America highlighted how elevated ambient temperatures compound respiratory distress in infants. Overheating impairs an infant's natural arousal mechanism, preventing them from waking when experiencing apnea or hypercapnia.

Caregivers frequently overbundle infants out of fear that the child will catch a chill. Heavy swaddles, fleece sleep sacks, and unventilated rooms elevate core body temperatures rapidly. Sweating, damp hair, flushed cheeks, and rapid breathing indicate dangerous thermal stress.

Current newborn care protocols recommend maintaining the nursery between 68°F and 72°F (20°C to 22°C). One breathable layer of clothing, coupled with a wearable sleep sack that leaves arms free once rolling begins, provides sufficient warmth without introducing loose bedding or excess heat.
