In the early years, managing extreme heat isn't just about "dealing" with a hot day—it is a critical safeguarding responsibility. Because babies and young children have underdeveloped temperature regulation, they are at higher risk of heat exhaustion and heatstroke.
Moving away from reactive "panic" management, this training module outlines a proactive Heatwave Readiness strategy designed to keep your entire cohort, from infants to pre-schoolers, safe and comfortable.
1. Environmental Readiness: Controlling the Climate
Prevention begins long before the temperature peaks. Your goal is to keep the ambient temperature stable and prevent the "oven effect."
-
The Shade & Shield Protocol: Keep curtains, blinds, and windows closed during the hottest part of the day (11 am – 3 pm) to block direct solar gain. Only open windows early in the morning or late at night when the external air temperature is lower.
-
Safe Airflow: Fans are an effective tool, but they must be used correctly. Never aim a fan directly at a child, as this can increase dehydration; instead, use them to circulate air in the room. If indoor temperatures exceed 35°C, turn off fans as they will only be circulating hot air.
-
Surface Temperature Audits: Remember that outdoor equipment absorbs heat. Before allowing children into the garden, touch metal slides, railings, and rubber play surfaces. These can reach temperatures capable of causing contact burns in seconds.
2. Hydration: The "Little and Often" Strategy
Children often don't recognise the early signs of thirst, especially when they are distracted by play.
-
Proactive Sips: Do not wait for children to ask for a drink. Implement a rolling hydration schedule where fluids are offered every 30 minutes.
-
Beyond Water: While water is the primary source of hydration, incorporate water-rich foods into your snack menu, such as cucumber slices, watermelon, or melon.
-
Infant Specifics: Breastfed babies do not need extra water; they may simply want to feed more frequently. For bottle-fed babies who can have water, cooled boiled water can be offered between feeds.
3. Recognising the Signs: From Heat Stress to Emergency
Knowing the difference between heat exhaustion and heatstroke is vital.
-
Heat Exhaustion: Look for fatigue, dizziness, headaches, nausea, pale/clammy skin, fast breathing, and excessive thirst.
-
Heatstroke (Medical Emergency): This is life-threatening. Watch for hot, dry skin, high fever (above 40°C), confusion, rapid pulse, seizures, or loss of consciousness.
-
Action: If you suspect heatstroke, dial 999 immediately. While waiting for help, move the child to a cool area, remove extra clothing, and use cool (not cold) water to sponge them down.
-
4. Adjusting the Curriculum: "Low-Energy" Days
When the Met Office issues heat-health alerts, your curriculum must be dynamic and adaptable.
-
Peak Hour Protection: Suspend all vigorous outdoor activity and physical exercise between 11 am and 3 pm.
-
Sensory Cool-Downs: Replace active play with low-energy, water-based sensory experiences. A shallow water tray with cool water, damp flannels for necks and wrists, or calm "ice exploration" play in the shade can help regulate body temperature while keeping learning objectives alive.
-
Uniform Adjustments: Encourage parents to provide loose, lightweight, light-coloured clothing made from breathable natural fibres like cotton.
Strategic Training Checklist for Your Team
-
[ ] Room-by-Room Audit: Identify the coolest rooms in your setting and have a plan to relocate groups if a specific room becomes too hot.
-
[ ] First-Aid Refresh: Ensure your first-aid kits are stocked with rehydration salts, cooling sponges, and temperature strips.
-
[ ] Parental Communication: Send a "Summer Safety" briefing to parents, advising on clothing choices, sun safety, and the importance of high-factor sunscreen applied before arrival.
-
[ ] The "Watch and Wait" Protocol: Brief your staff on the signs of heat stress. Encourage them to be "professionally curious"—a child who is suddenly unusually irritable or quiet may be struggling with heat.
The Bottom Line: Your goal is to create a "Heatwave Plan" that is so embedded in your setting's routine that it feels like a natural part of your day, rather than a frantic response to an emergency. By controlling the environment, staying ahead of hydration, and adapting the curriculum, you ensure the summer remains a season of discovery, not danger.
What is the one outdoor area in your setting that becomes a "sun trap," and how will you adapt your planning to keep that space safe during peak hours?
