Dzeltenais karstuma brīdinājums

17.07.2026. no dienas vidus Latvijas dienvidu daļā gaidāms stiprs karstums - gaisa temperatūra paaugstināsies līdz +27...+28º. ESI INFORMĒTS, ka ir gaidāms stiprs karstums! Karstums rada papildu slodzi sirds un asinsvadu, kā arī elpošanas orgānu sistēmām. Vecāki cilvēki, zīdaiņi, kā arī citu vecuma grupu pārstāvji, kas sirgst ar hroniskām saslimšanām, tiek pakļauti veselības traucējumu riskam! Stipra karstuma laikā vairāk nekā ierasts, cilvēku izvēlas atpūsties pie ūdens, kas paaugstina potenciālo nelaimes gadījumu risku. Pārkarsis cilvēks nedrīkst strauji iet aukstā ūdenī! Strauja temperatūras maiņa var izraisīt sirds ritma traucējumus un pēkšņu nāvi. Neesi pārgalvīgs un izvērtē savu peldētprasmi! Dienas vidū UV indekss sasniegs vidēji augstu līdz augstu līmeni, tādēļ nav ieteicams ilgstoši atrasties tiešos saules staros.
