Aging is a natural and inevitable stage of human life, accompanied by extensive changes across physical, psychological, social, and cognitive domains (
1). As individuals grow older, the functionality of various bodily systems declines, motor abilities diminish, and the likelihood of developing chronic conditions such as diabetes, hypertension, cardiovascular, respiratory, and musculoskeletal diseases increases. Alongside these physiological changes, elderly individuals may also face psychological challenges such as anxiety, depression, memory loss, and feelings of isolation (
2). These factors collectively render older adults one of the most vulnerable populations in special circumstances, including mass gatherings and religious events (
3).
Among such events, the Arbaeen pilgrimage stands out as one of the largest religious gatherings in the world, annually attracting millions of pilgrims from various countries to Karbala, Iraq (
4). Rooted in Shia Islamic tradition, this pilgrimage symbolizes devotion, sacrifice, solidarity, and loyalty to the ideals of Imam Hussain (AS) (
5). Pilgrims often walk long distances — sometimes exceeding 80 kilometers — under challenging environmental conditions, including extreme weather, crowded pathways, and limited access to facilities (
6). The participation of elderly individuals in this pilgrimage, despite physical and psychological limitations, reflects deep religious conviction, spiritual motivation, and a desire for active engagement in sacred rituals (
7).
However, the involvement of older adults in the Arbaeen pilgrimage presents serious health challenges (
8). Long walking distances, adverse environmental conditions, inadequate hygiene and medical services, and the absence of tailored support systems can jeopardize their physical and mental well-being (
9). Moreover, the lack of comprehensive planning, infrastructural weaknesses, and insufficient training for volunteers and caregivers further increase their vulnerability (
10). In such a context, a systematic and scientific examination of the health challenges faced by elderly pilgrims during Arbaeen becomes an urgent necessity (
11).
Studying this issue is not only important from a public health perspective but also holds ethical, cultural, and social significance. Addressing the needs of elderly participants in religious ceremonies reflects societal maturity and respect for human dignity. Furthermore, enhancing the health and safety of this group can improve their spiritual experience, reduce medical burdens, and contribute to better management of large-scale events. Therefore, this review article aims to explore the multifaceted health challenges of elderly individuals during the Arbaeen pilgrimage by analyzing existing literature and offering practical recommendations to improve their conditions.
