Dublin’s homeless population is facing severe challenges as a heatwave grips the city. The Journal visited the Lighthouse homeless café to assess the impact of the rising temperatures on vulnerable individuals. Those without permanent housing are struggling to find shade and stay hydrated, with tents offering limited relief from the sun. Services like the Lighthouse are essential, but resources are stretched as they attempt to provide support during the extreme weather. The situation highlights the precariousness of life without shelter, particularly during increasingly frequent heat events. Access to basic necessities like water and cool spaces is crucial for preventing heat exhaustion and other health risks for those experiencing homelessness.
