Il periodo di canicola iniziato mercoledì scorso proseguirà almeno fino a martedì prossimo. La giornata più calda a sud delle Alpi, secondo Meteosvizzera, sarà quella di domenica, quando si toccheranno i 35 gradi. Intanto i livelli di ozono: a Mendrisio si sono toccati i 260 microgrammi per metro cubo (il limite di ordinanza è di 120). Il Gruppo operativo salute e ambiente ha quindi nuovamente invitato oggi (venerdì) la popolazione a seguire tutta una serie di raccomandazioni.
La carta svizzera dei pericoli
Sono quelle usuali in queste circostanze, ovvero bere molta acqua, consumare pasti leggeri ed evitare sforzi intensi nelle ore più calde, quando è invece consigliato restare in casa o al fresco. Si consiglia inoltre di impedire al caldo di entrare in casa, oscurando le finestre di giorno e arieggiando di notte, e di rinfrescarsi frequentemente con docce e bagni.
Si chiede inoltre di verificare se vi siano parenti o conoscenti che necessitano di aiuto. Particolare attenzione va prestata alle persone molto sensibili, come bambini piccoli, anziani, malati cronici.
