During periods of hot weather, babies are among the most vulnerable. Their bodies are less able to regulate their temperature, they sweat less and can become dehydrated very quickly.
The Health Directorate reminds people never to leave a baby alone in a car, even for just a few minutes. The temperature inside a vehicle can rise very quickly and reach dangerous, even fatal, temperatures, even when the windows are left slightly open.
It is also important never to leave a child in a pushchair or car seat in direct sunlight, and never to cover a pushchair with a blanket or cloth, as this blocks air circulation and can cause heat to build up.
During hot weather, babies may need to be fed more frequently.
To reduce the effects of the heat:
Applying ice directly to a baby's skin is not recommended, as it can cause burns and trigger shivering, which increases the body's heat production.
Even during hot weather, safe sleep guidelines remain essential. Babies should be dressed lightly, and thick blankets, duvets, pillows, soft toys and other objects should be kept out of the cot, as they prevent heat from escaping and may contribute to overheating.
Parents should be alert to signs that may indicate dehydration or a heat-related illness:
If any of these signs are present, particularly marked drowsiness or fever, parents are advised to contact a doctor without delay.
