An anticyclone – a high-pressure area – named Cerberus (named after the monster from Dante’s Inferno) coming from the south will cause temperatures to rise above 40°C across much of Italy. This comes after a spring and early summer full of storms and floods.
The highest temperature in European history was broken on 11 August 2021, when a temperature of 48.8°C was recorded in Floridia, an Italian town in the Sicilian province of Syracuse. That record may be broken again in the coming days.
Though as cheaper preventative would be just electrolyte sports drink. Meant for same thing just for sports caused sweating. However sweating is sweating.
Main thing is one can buy electrolyte sports drink by big drink mix powder jar, instead of expensive single pack.
One just has to be carefull to buy the actual rehydration drink mix instead of the normal sports drink. The normal sports drink isn’t as optimal as thirst killer, since container alottaa of calories. It does also usually contain rehydration sales, but as said heck of energy bomb to be drink by bottle full outside of hard exercising. Where is pure rehydration drink has just set of salts and then maybe some flavoring and food color (because obviously sports drink is supposed to be acid green)
Ofcourse most likely not exactingly proportioned and controlled as actual ORS from pharmacy, since ORS would be done to medicine production standards.
If you want cheap you can easily make ORS yourself. Organizations like the WHO and the CDC have recipes.
Sports drinks have all kinds of unnecessary crap in them I think.
