This study assesses heat stress in high-density residential areas of Bauchi Town. It uses field measurements and surveys to evaluate environmental conditions and human comfort. Objectives: To assess heat stress levels in high-density residential areas of Bauchi Town., to measure environmental parameters influencing heat stress (temperature, humidity, airflow), to evaluate spatial variation of heat stress within selected high-density neighborhoods, to assess residents’ perception of heat stress and thermal comfort, to identify urban design factors contributing to heat stress and to propose mitigation strategies for reducing heat stress in Bauchi. Methodology: Quantitative approach was adopted. The study was conducted in Bauchi Town, located in northeastern Nigeria. The area experiences a hot–dry climate with high temperatures and seasonal variations. The findings suggests that urban planning strategies would reduce heat stress and improve living conditions in hot–dry climates. The study unveiled that high density residential areas exhibit higher heat stress levels, nightmare stress heat is more pronounced high density residential areas, urban form significantly influences heat stress and that residents of high-density residential areas report high thermal discomfort.
