YSK you can take advantage of free air conditioning in designated public spaces to beat the heat.
Many Californian cities have designated Cool Zones sites. These are air-conditioned settings where seniors and others can gather to escape the heat. For example, the libraries in my area are all designated cool zones.
Anyone can take advantage of these sites to escape the heat and there may be one close to you. It’s free and you can linger as long as you need to, at least until closing. Libraries also offer free wifi, if you are able to work online.
If you are not in California, check online for similar programs in your area.
Seniors are especially susceptible to heat sickness and death so please remember to check on elderly neighbors and relatives during high heat times.
