Children are more likely than adults to suffer in hot weather—here’s a comprehensive, NHS-endorsed guide to help childcare providers and families manage safely.

1. Hydration: The Critical First Line of Defence 💧

• Offer fluids frequently, not just at meal or snack time—children may not recognise thirst early. Use cool water, diluted fruit juice, or rehydration drinks as suitable for age

• Babies under 6 months: breastfeed on demand or provide small amounts of cooled, boiled water alongside formula feeds.

• Older babies (6+ months): water becomes essential. Offer sips throughout the day, especially when active or heated.

• Snacks matter: include water-rich foods such as melons, cucumbers, and lower-sugar ice lollies (for toddlers, pre-meals to avoid tooth decay) .

2. Keeping Cool: Environmental & Practical Measures

Indoor Cooling

• Control indoor climate: close curtains and windows during the hottest part of the day, and open them when outside temperatures drop. Fans are fine if the room stays below ~35 °C, but never aim airflow directly at children to avoid dehydration.

• Night-time environment: cool baths before bed and minimal sleepwear help keep overnight temperatures down. Aim for 16–20 °C in children’s bedrooms .

Outdoor Cooling

• Supervised water play: paddling pools, cool showers, or spray bottles are excellent—but always supervise, and keep play areas in the shade.

• Early or late outings: reserve outdoor time for before 11 am or after 3 pm.

• Check play surfaces like slides/railings—they heat up fast and can cause burns.

3. Recognising & Responding to Heat-Related Illness

Heat Exhaustion

• Key symptoms: fatigue, dizziness, headaches, nausea, cramps, pale/clammy skin, fast breathing, thirst, weakness. Children might also show irritability or sleepiness.

• Treatment steps (NHS 4-step cool-down):
  1. Move to a cool place
  2. Remove extra clothing
  3. Offer cool water or rehydration drink
  4. Cool the skin via sponging or cold packs under armpits/neck/fan 

• Monitor for improvement: if no better in 30 minutes, consult NHS 111.

Heatstroke

• Warning signs: hot, dry skin, high temperature, confusion, seizures, fast pulse/breathing, unconsciousness.

• Emergency action: dial 999 immediately, cool them down using the same methods, and if unconscious, place them in the recovery position—do not delay .

4. Prevention: Proactive Planning & Daily Routine Adjustments

• Plan around heat peaks: be alert to NHS/Met Office heat-health alerts and aim to limit high-energy outdoor activities during those times.

• Prepare environments ahead: identify coolest rooms, ensure access to clean drinking water, have cold clothes or towels ready.

• First aid readiness: include rehydration salts, temperature strips, water, and cooling sponges in kits for childcare settings or outings .

• Community care: check in on all children frequently—and also those in vulnerable households like babies or those with health conditions .

With consistent application of NHS-endorsed measures—hydration, environmental adjustments, vigilant symptom recognition, and thoughtful planning—you’ll ensure children stay safe and comfortable during hot weather.
