How to Keep a Newborn Cool and Safe During a Heat Wave

Keep a newborn out of direct sun and parked cars, use light layers, preserve safe sleep, and know when heat exposure calls for medical help.

Keep a newborn out of direct sun and parked cars, dress them in light layers, and remove excess bedding without changing safe-sleep practice. Check the room and the baby’s chest or back of the neck; if your home is dangerously hot, move to an air-conditioned place. For an exclusively breastfed baby under six months, offer feeds more often rather than giving extra water. Get medical help if the baby seems ill, and call emergency services for severe symptoms such as breathing difficulty or unresponsiveness.

Cool the room while keeping sleep safe

The NHS describes 16–20°C as a comfortable room temperature for a sleeping baby. A room thermometer can help you monitor conditions, though a heat wave may make that range difficult to reach. If your home is too hot and you do not have air-conditioning, go with the baby to an air-conditioned public place or cooling shelter. Keep the baby supervised and use safe transport and sleep practices while you are there.

Use a fan only with care. NHS guidance says not to aim it directly at the baby. CDC general household guidance says fans should be used only when indoor temperatures are below 90°F; above that, a fan can increase body temperature. That threshold is general heat advice, not a newborn-specific recommendation. When a cooled indoor location is available, use it rather than relying on a fan in a hotter room.

Reduce layers, not safe-sleep protections

In hot weather, a single lightweight clothing layer may be enough. On the warmest nights, a nappy alone may be appropriate. Remove a layer if the baby’s chest or the back of their neck feels hot or they are sweating. Cool hands and feet by themselves do not reliably mean the baby is cold.

Keep the baby on their back in a separate, clear sleep space, following local safe-sleep guidance. Remove excess clothing and bedding rather than adding loose covers. Do not cover a pram or stroller with a blanket or muslin: it can trap heat.

Protect the baby outdoors and in the car

Babies under six months should be kept out of direct sunlight. Use shade, such as a clip-on parasol or stroller sunshade, and choose a cooler place when possible. A shade does not make it safe to leave a baby in a hot or enclosed space.

Never leave a baby in a parked car, even briefly or with a window cracked. CDC reports that a parked car’s interior can rise almost 20°F within the first 10 minutes even when a window is cracked open. That figure describes the reported rise, not a prediction for every car or weather condition. Take the baby with you whenever you leave the vehicle.

Keep feeding appropriate for the baby’s age

For an exclusively breastfed baby aged 0–6 months, Norfolk Healthy Child Service advises against giving extra water in hot weather. Offer breastmilk or expressed milk more often instead. Watch wet nappies and urine color as part of monitoring hydration. Breastmilk or infant formula should remain the main drinks during the first year; follow your clinician’s advice for your baby’s circumstances.

Know when to get medical help

Seek urgent medical advice if you are worried or the baby may be ill. In the UK, NHS guidance is to request an urgent GP appointment or contact 111. Call 999 if the baby stops breathing, struggles for breath, will not wake, has a seizure, becomes limp or unresponsive, or suddenly turns pale, blue, or grey. These contact routes are UK-specific; elsewhere, use your local pediatric urgent-care and emergency services.

This is preventive guidance, not a diagnosis. If the baby seems unwell after heat exposure, contact a medical professional rather than trying an unverified home treatment.
