Urban stress is an important cause of physical and mental diseases in cities and access to urban services is one of the most important issues of today's urban planning. Therefore, urban planners and designers must pay special attention to them in their plans and designs. However, even though many studies have separately addressed urban stress and access to urban services in recent years, no study has been conducted to explain the relationship between the two. For this purpose, the present research was conducted to explain the relationship between urban stress and access to services in District 8 of District 1 in Tehran municipality, which is the most stressful district in this region according to experts. The research findings reveal that the value of the correlation coefficient between the independent and dependent variables is 0.790, which indicates a high correlation between access to services and urban stress. Moreover, the adjusted or modified coefficient of determination shows that 61% of the total changes are the stressfulness of the living environment of people dependent on access to urban services in their lives. Additionally, by using beta coefficients, indicators of access to green space, educational services, religious services, sports services, medical services, and transportation services are respectively the most important service indicators affecting the stress of citizens. Also, access to green space services, sports services, and religious services reduces citizens' stress, while proximity to educational services, transportation services, and medical services increases their stress. As a result, urban stress can be significantly reduced by paying special attention to the design and planning of educational services, transportation services, and medical services, as well as improving access to green space services, sports services, and religious services.
