Heatwave Danger: Keep Babies Cool Safely
26 May
Summary
- Overheating increases the risk of sudden infant death syndrome.
- Ideal baby room temperature is between 16 and 20 degrees Celsius.
- Never cover prams with blankets; this traps heat and restricts airflow.

With temperatures soaring to 35 degrees Celsius, the UK faces its hottest day since 2020, prompting urgent advice for parents to keep infants safe and cool. The Lullaby Trust highlights that overheating significantly elevates the risk of sudden infant death syndrome (SIDS), emphasizing that a baby's room should ideally be between 16 and 20 degrees Celsius.
To combat rising indoor temperatures, parents are advised to block direct sunlight with blinds and use fans for air circulation, ensuring they are placed out of reach and not directly on the baby. Reducing a baby's clothing to as little as a nappy is recommended, alongside close monitoring of room temperatures with a thermometer.
Signs of overheating, such as hot or clammy skin on a baby's chest or neck, require immediate action. Similar precautions apply outdoors; prams should be shaded with clip-on shades allowing airflow, but never covered with blankets, which can dangerously trap heat. Avoiding travel during peak heat, especially on public transport, and seeking cooler indoor environments is also encouraged.
