Why was sand a Heath threat for Egyptians?

Sand posed a health threat for ancient Egyptians primarily due to its role in respiratory issues. Dust storms could carry fine particles that led to respiratory conditions, exacerbating illnesses like Asthma and other lung diseases. Additionally, sand could contaminate water sources and food supplies, leading to gastrointestinal problems and other health issues. The harsh desert environment also contributed to the challenges of maintaining hygiene and sanitation.
