Summer has finally arrived, bringing with it endless days, clear skies, and an uncontrollable desire to disconnect from the daily routine. Along with the beautiful season, however, the true bugbear of these months punctually appears: the muggy heat. When temperatures constantly exceed thirty degrees and humidity makes the air dense and heavy, everyone’s primal instinct boils down to a single goal: to look for water. In this scenario, the outdoor swimming pool transforms into a true oasis in the desert, the ideal refuge to escape the scorching asphalt and concrete of the cities.

However, lounging by the poolside or diving in when the thermometer skyrockets requires attention. If not managed correctly, in fact, the combination of beating sun, oppressive mugginess, and the mirrored reflection of the water can turn a day of well-deserved relaxation into a nightmare marked by heatstroke, congestion, and painful sunburns. In this article, we will see how to make the most of the outdoor pool during heatwave days, protecting your health and maximizing comfort.

The first psychological mistake we make when going to the pool in the middle of summer is thinking that water is a total and impenetrable shield against environmental heat. In reality, it is not. The water in an outdoor pool accumulates the sun’s thermal energy hour after hour, especially in the critical months of July and August. When the temperature of the water surface exceeds 28-30 degrees, its cooling power decreases drastically, canceling out that initial pleasant shivering sensation.

Furthermore, a biological factor that is often ignored comes into play: when we are submerged, our body cannot sweat efficiently. Sweating is the primary mechanism the body uses to thermoregulate and expel excess heat through evaporation. Under water, this process is blocked. This means that, even if we do not visibly perceive it, we are still losing precious fluids and our internal temperature can rise dangerously. Understanding this biological mechanism is the first fundamental step to adopting conscious behaviors by the poolside.

Precisely because of “invisible” sweating in the water, the risk of dehydration at the pool is extremely high. Many make the mistake of drinking only when they feel the sensation of thirst, but by that point, the body is already in a partial fluid deficit.

To keep the body cool and responsive, it is necessary to drink in small sips every twenty or thirty minutes. Still water at room temperature or cool (never ice-cold, to avoid congestion) remains the best choice. If you spend many hours in the sun, it is advisable to supplement with drinks rich in mineral salts (potassium and magnesium) to replenish lost electrolytes. On the other hand, sugary drinks, alcohol, and excess caffeine should be absolutely avoided: they increase diuresis and accelerate dehydration, worsening the body’s tolerance to heat.

Another critical element is ultraviolet radiation. Pool water acts like a mirror, reflecting up to 20% of the sun’s rays back onto our bodies. This means that the dose of radiation hitting the skin by the poolside is significantly higher than what we would receive in a shaded garden.

Sunscreen with a high protection factor (SPF 30 or 50+) is not an option, but a requirement. It should be applied at least twenty minutes before exposure and rigorously reapplied every two hours, or immediately after every swim, even if the label says “waterproof”. Do not forget sensitive areas: ears, neck, the tops of the feet, and lips require specific products and frequent applications.

Surviving the muggy heat also requires good management of spaces and schedules. Here are some golden rules to follow:

By following these simple but crucial precautions, the outdoor swimming pool will stop being an insidious place and return to being what it should be: an oasis of pure well-being and relaxation where you can regenerate body and spirit even during the hottest summers.
