The World Health Organization (WHO) has urged authorities to strengthen heat protection measures during the Arbaeen pilgrimage of Imam Hussain (peace be upon him), warning that extreme summer temperatures could pose significant health risks to pilgrims, volunteers, and healthcare workers participating in the annual event.

In a statement, WHO said its preliminary heat risk assessment for Iraq indicates that daytime temperatures along parts of the pilgrimage routes could reach approximately 45°C, while nighttime temperatures may remain above 30°C in some areas. The organization stressed the importance of preventive measures to reduce cases of heat exhaustion, dehydration, and heatstroke.

WHO noted that the Arbaeen pilgrimage is one of the world's largest annual mass gatherings, with more than 22 million visitors expected. Many pilgrims travel long distances on foot, increasing their exposure to heat-related illnesses.

According to the assessment, ten Iraqi provinces—including Karbala, Najaf, Babylon, and several southern governorates—have been identified as high-risk areas for heat-related health conditions during the summer.

WHO Representative in Iraq, Jameela Al-Raiby, emphasized that protecting pilgrims' health is a shared responsibility, calling for coordinated efforts to ensure the availability of safe drinking water, shaded rest areas, accessible medical services, and effective public health awareness campaigns.

The organization also encouraged pilgrims to stay well hydrated, rest regularly in shaded or air-conditioned areas, wear lightweight clothing, and take extra precautions for vulnerable groups, including older adults, children, pregnant women, and people with chronic medical conditions. Pilgrims experiencing symptoms such as heat exhaustion, dizziness, or fainting were urged to seek medical attention immediately.
