Here are some tips from the CDC on how to stay cool in extreme heat:
If you don't have air conditioning you can cool down by spending some time at air conditioned public places such as the Fairfield libraries, the Bigelow Center for Senior Activities or Black Rock Church which are serving as cooling centers this week. Local malls and movie theaters are also great options to beat the heat.
