As global temperatures rise and extreme heat becomes more frequent, those living and working in some of the world’s hottest regions offer practical insights into managing life in sustained high temperatures. From Peru to Greece, and from Saudi Arabia to Namibia, locals have developed strategies to cope with daily heat that often exceeds 40 degrees Celsius.

In Peru’s Chira River valley, where the city of Piura endures consistent high heat, Luis Pacherrez Antón, president of the Agroperu Cooperative, highlights the importance of adjusting work schedules. Farmers begin early in the morning to avoid peak sun intensity and rely on locally grown, hydrating fruits such as bananas and papayas to maintain energy levels.

Similarly, Obada Almaitah, a diving instructor in Aqaba, Jordan, where temperatures regularly hit 40 C, schedules physically demanding tasks in the early morning hours to avoid the harsh afternoon sun. Greece’s Acropolis tour guide Despina Savvidou has witnessed changing climate patterns over her 48-year career, noting that what was once considered a heatwave is now the norm. She advises tourists to take early tours before the site opens to avoid the hottest hours.

Hydration is universally emphasized. Egyptian archaeologist Dr. Zahi Hawass stresses the importance of drinking water regularly throughout the day rather than waiting until feeling thirsty. In the humid heat of Jeddah, Saudi Arabia, Dr. Sherene M El-Sioui notes that drinks such as laban—a yogurt-based beverage—are popular for replenishing electrolytes. Drinking slowly and steadily is recommended to maintain hydration without overwhelming the body.

Cooling methods vary from the practical to the traditional. Namibia’s wildlife ranger John Napolo carries multiple liters of water daily and uses some to pour over himself to cool down. Researchers at the University of Sydney endorse tipping water over the skin to enhance evaporative cooling, which is less physiologically taxing than sweating alone. The use of ice towels around the neck, as observed in professional tennis, provides rapid relief during short rest periods.

Daily routines often include multiple warm showers to refresh without causing shock to the body, a practice endorsed by Greece’s Savvidou and Saudi Arabia’s El-Sioui. In regions such as northern Canada, where record temperatures pushed above 40 C, medical officers recommend immersing children’s legs in cool water as a quick cooling technique.

Work schedules also adapt to heat extremes. In Djibouti and Sicily, authorities limit work during mid-day peak heat hours, urging extended breaks in shaded areas to prevent heat-related illnesses. Workers generally prefer early mornings and late afternoons for outdoor tasks.

Dietary habits also reflect heat adaptation. Light meals with high water content—such as salads, chilled soups, and hydrating fruits—are favored in Spain, Greece, and India. Foods and beverages with cooling properties, like coconut water, buttermilk, and fresh fruits, are commonly consumed to maintain hydration and electrolyte balance.

Clothing choices challenge common assumptions about heat management. Loose, flowing garments made from breathable fabrics dominate in hot climates, providing both sun protection and airflow. Covering skin rather than exposing it, as practiced in Namibia and Saudi Arabia, helps conserve moisture and reduce sun exposure.

Accessories like wide-brimmed hats, visors, sunglasses with UV protection, and traditional hand fans remain crucial. In Vietnam and Spain, portable fans and parasols continue to provide portable shade and airflow amid rising heat.

Although air conditioning is widely available, experts encourage sustainable alternatives such as ceiling and pedestal fans, nighttime ventilation, and strategic use of shutters or blackout curtains to keep interiors cool. These measures, combined with long-standing local knowledge about living with heat, offer valuable lessons as more regions face unprecedented temperatures.

A simple thermometer is also advocated to monitor indoor temperatures and determine optimal times to open windows for ventilation, helping to balance heat relief with comfort.

As global heat intensifies, these practical strategies from some of the world’s hottest places provide a blueprint for adapting daily life to extreme climates.
