An individual may produce as much as 2 to 3 gallons of sweat per day. To replenish that fluid you should drink 3 to 4 cups of water every hour.<br \/>\nTake breaks: Taking breaks in a cool shaded area and allowing time for recovery from the heat during the day are effective ways to avoid heat-related illness.<br \/>\nAvoid some beverages: Avoid or limit the use of alcohol and caffeine during periods of extreme heat. Both dehydrate the body.<br \/>\nStop and rest: If you start to feel symptoms such as nausea, dizziness, weakness or unusual fatigue, rest in a cool shaded area. If symptoms persist or worsen seek immediate medical attention.<br \/>\nClothing: Whenever possible, wear clothing that provides protection from the sun but allows airflow to the body. Protect your head and shade your eyes when outdoors.<br \/>\nBe prepared: When in the heat be sure to pay extra attention to those you\u2019re with and be sure you know how to call for medical attention.<\/p>\n<p>For information about cooling centers operated by Los Angeles, Orange, Riverside and San Bernardino counties, see <a href=\"https:\/\/ready.lacounty.gov\/heat\/\" target=\"_blank\" rel=\"nofollow noopener\">https:\/\/ready.lacounty.gov\/heat\/<\/a>, <a href=\"https:\/\/ocgov.com\/cooling-centers\" target=\"_blank\" rel=\"nofollow noopener\">https:\/\/ocgov.com\/cooling-centers<\/a>, <a href=\"https:\/\/capriverside.org\/cool-centers\" target=\"_blank\" rel=\"nofollow noopener\">https:\/\/capriverside.org\/cool-centers<\/a> and <a href=\"https:\/\/dph.sbcounty.gov\/extreme-heat-information-and-resources\/\" target=\"_blank\" rel=\"nofollow noopener\">DPH<\/a>.<\/p>\n<p>For more local weather alerts, visit our <a href=\"https:\/\/www.pasadenastarnews.com\/weather-advisory\/\" target=\"_blank\" rel=\"nofollow noopener\">Weather Advisory page<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"Los Angeles County is the focus of an updated heat advisory released at 12:11 a.m. on Tuesday by&hellip;\n","protected":false},"author":2,"featured_media":406347,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[27],"tags":[48,52,51,47,50,49,334],"class_list":["post-406346","post","type-post","status-publish","format-standard","has-post-thumbnail","category-los-angeles","tag-la","tag-la-headlines","tag-la-news","tag-los-angeles","tag-los-angeles-headlines","tag-los-angeles-news","tag-weather-advisory"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/406346","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/comments?post=406346"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/posts\/406346\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media\/406347"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/media?parent=406346"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/categories?post=406346"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us-ca\/wp-json\/wp\/v2\/tags?post=406346"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
