Summer sunshine can be wonderful, but for children living with congenital heart defects (CHD), high temperatures can also bring extra challenges. Heat can put additional strain on the heart and body, making it even more important for heart families to take precautions and stay cool.
Whether you’re planning a park day, enjoying outdoor playtime, or simply navigating a heatwave at home, here are practical tips to help your child stay safe and comfortable.
Hydration is Essential
Children with CHD can be more prone to dehydration, so it’s important to encourage regular water intake—especially when it’s hot.
- Keep water nearby at all times, even during indoor play.
- Avoid drinks with caffeine or high sugar content, as these can make dehydration worse.
- Take a refillable water bottle on all outings to make sipping easy and fun.
Stay in Cool Environments
The hottest part of the day (usually between 11 AM and 4 PM) can be particularly taxing for children with heart conditions.
- Stay indoors in a cool space during peak heat.
- Use fans, air conditioning, or cooling centres in your community.
- Plan activities earlier in the morning or later in the evening when it’s cooler outside.
Dress Smart for Hot Weather
- Choose lightweight, light-coloured, and loose-fitting clothing to help the body breathe.
- Cotton or moisture-wicking fabrics are best to prevent overheating.
- Don’t forget wide-brimmed hats and sunglasses to protect from direct sunlight.

Know the Signs of Heat-Related Illness
Children with CHD may be more vulnerable to heat exhaustion or heatstroke. Watch for:
- Unusual tiredness or weakness
- Dizziness or fainting
- Nausea or vomiting
- Excessive sweating or flushed skin
- Rapid breathing or heart rate
If you notice any of these symptoms, move your child to a cooler area, give them water, and call your healthcare provider. Always follow your cardiac team’s advice, and in an emergency, seek immediate medical help.
Every child is unique, and some may tolerate heat better than others. Trust your instincts as a parent or caregiver, and always refer to your care provider’s specific advice for your child’s heart condition.
Staying cool isn’t just about comfort—it’s about keeping those little hearts safe and healthy during the summer months.
