Aquatic therapy, a water-based approach to physical and mental well-being, leverages water’s properties like buoyancy and hydrostatic pressure for therapeutic benefits. It holds particular promise for individuals with autism spectrum disorder (ASD), characterized by social, communication, and sensory processing challenges. Alternative therapies like aquatic therapy are gaining attention for their potential to complement traditional treatments by improving quality of life and reducing symptoms. Individualized approaches are vital in ASD care due to the spectrum’s diversity, tailoring interventions to specific needs, strengths, and challenges. Aquatic therapy’s benefits for ASD include sensory regulation, motor skill development, and social interaction enhancement, providing a supportive environment for therapeutic activities. Despite obstacles like limited access and costs, aquatic therapy remains a promising component of holistic autism care, highlighting the need for expanded research and improved practices to maximize its effectiveness and accessibility.
