A Resort Heat Action Plan: Shade, Water, Staff and Vulnerable Guests

Highest risk sits with adults aged 65 and older, infants and young children, pregnant women, people with disabilities and people with chronic cardiovascular, respiratory, kidney or diabetic conditions. Many also take medications that blunt thirst or reduce sweating, so they can overheat before they notice. To identify them respectfully, avoid direct health questions. Instead, make a general offer at check-in covering cool hours, water locations and the possibility of a cooler room, and ask reception to note older guests and families with small children. Guests volunteer the information they feel is relevant, and the offer itself is the safety net.

There is no single safe number for every site: the threshold depends on local climate, humidity, wind and how acclimatised guests are. The WHO principle is to avoid outdoor exertion during the hottest part of the day. Concrete triggers should be set by a clinician or local health authority for your location, often using the heat index rather than air temperature alone. A practical ladder is: level one on ordinary hot days, level two when the heat index reaches your agreed point, and level three during an official heat alert, when you move activities to the cooler hours and step up pool and beach checks from the morning.

The exact volume depends on activity and climate, so it is more practical to plan for accessibility than litres: water should be within a short walk of the pool, beach access, outdoor restaurants and any queue. WHO advises drinking regularly rather than waiting for thirst and avoiding sugary, alcoholic and caffeinated drinks that dehydrate. Assign each station an owner who fills, chills and sanitises the dispensers daily, and verify them on every shift, especially at the highest response level when demand peaks and heat makes water quality more critical.

Heat exhaustion is the earlier stage: dizziness, headache, nausea, weakness and heavy sweating. Move the guest to shade or a cool room, offer water and keep observing. Heatstroke is a medical emergency marked by hot dry skin, confusion, convulsions or loss of consciousness. In that case call emergency medical help immediately and cool the person while you wait — cool water on the skin, air movement and shade. Because the two are easy to confuse under stress, rehearse both scenarios with staff before the season and keep the one-page first-response card at every station.

Closing the pool outright is rarely necessary, but at the highest response level it is sensible to limit time in direct sun and shift activity to the cooler morning and evening hours, as WHO advises. Rospotrebnadzor similarly recommends avoiding open sun in peak midday hours. On an official alert, reschedule or shorten daytime excursions, strengthen supervision of the water area and steer guests to shade, water and cool spaces. Base the decision on the triggers you set with a clinician rather than on the spot, so every shift enforces the same rule.

Many medicines — from diuretics to blood-pressure drugs — alter temperature regulation or blunt thirst, so the guest may overheat without warning. A resort must not give medical advice, but it can act practically: offer a cooler room, point out hydration stations, advise avoiding open sun in peak hours and tell the guest how to reach the on-site medical point. WHO also reminds travellers to check that medications are stored at the correct temperature and protected from heat. If the guest feels unwell, encourage them to see a clinician, because the medical decision stays with a professional.

The review should close the loop that WHO treats as essential to any heat plan: monitoring, evaluation and learning. Revisit every incident and near-miss recorded during the season, and check whether each trigger fired too late, too early or exactly on time. Ask which shade and water points were overused and which went unnoticed, whether multilingual communication reached guests, and whether staffing coped on peak alert days. Then update the temperature thresholds, add shade where guests clustered, refine the training and revise the task cards so that next season inherits the lessons instead of repeating them.
