It\u2019s officially the \u201cDog Days\u201d of the summer season \u2014 and they\u2019re getting hotter and more humid thanks to the impact of the human-caused climate crisis<\/a>. <\/p>\n In extreme heat<\/a>, hydration is critical to prevent heat-related illnesses, such as heat stroke and heat exhaustion<\/a>. The adult body is 60 percent water, and drinking enough each day helps regulate body temperature, prevent infections, and maintain organ and other key functions.<\/p>\n Hydration multipliers – powders, packets, and liquid drops that you add to water – have become popular to boost that process and replenish electrolytes that are lost when we sweat. Electrolytes are substances that help your body to regulate chemical reactions and maintain the balance between fluids inside and outside your cells. Nearly every fluid and cell in the body contains electrolytes, according to the Cleveland Clinic<\/a>.<\/p>\n \u201cWhen we sweat, we lose more than just fluids, we also lose electrolytes \u2014 mostly sodium and chloride, but also smaller amounts of potassium, calcium, and magnesium,” Dr. Scott Braunstein, chief medical officer at medicine concierge company Sollis Health, told CBS News<\/a>. “While it all could all be replaced by drinking water and eating a variety of solid foods, for those not ready for a meal, drinking electrolyte-containing fluids is a great way to replace the losses in sweat.” <\/p>\n So, should you add a hydration multiplier to your water this summer? Here\u2019s what to know…<\/p>\n How they work<\/p>\n Hydration multipliers hydrate the body faster than water alone due to a process that takes place in the small intestine and rapidly pulls not just water, but other nutrients, into cells.<\/p>\n \u201cThe hydration multiplier maximizes your water uptake by using the sodium and glucose co-transport across the stomach while pulling water along,\u201d Texas Health explains<\/a>. \u201cWith such optimal sodium to glucose ratio, water gets transported into your body faster than if you drank water alone.\u201d<\/p>\n The formulas also carry potassium, calcium, and essential vitamins.<\/p>\n Experts recommend using them when exercising for long periods of time or following heat exposure. <\/p>\n \u201cWhen you drink plain water, it is absorbed primarily by osmosis through the walls of the intestine,\u201d registered dietitian Mia Syn told Vogue<\/a>. But if you\u2019re dealing with an imbalance of electrolytes\u2014say, you just ran a half-marathon or are feeling the effects of a few too many negronis \u2014 then plain water may not be absorbed as efficiently, she says.<\/p>\n There\u2019s nothing as good as plain water<\/p>\n Water is generally a safer bet than hydration multipliers because of what else might be on the ingredient list. <\/p>\n For example, some electrolyte drinks contain more sodium and sugar than nutritionists recommend you consume in a day. That may be harmful for people suffering from chronic conditions, such as diabetes. Too much sugar can lead to kidney damage in people who have diabetes.<\/p>\n \u201cElectrolyte drinks in general are safe for young athletes, but it\u2019s important to avoid any that contain caffeine,\u201d University Hospitals pediatric sports medicine specialist Dr. Laura Goldberg said<\/a>. \u201cMany people believe electrolyte drinks and powders are healthy, but they have a large amount of sugar which is unnecessary unless you\u2019re exercising for more than 60 minutes.\u201d<\/p>\n Too many electrolytes<\/a> can also lead to unintended consequences, such as weakness, headache, tremors, confusion, muscle cramping, rapid heartbeat, and gastrointestinal issues. Many of the signs of an electrolyte imbalance are similar to dehydration symptoms<\/a>. <\/p>\n Check with a physician before drinking hydration multipliers.<\/p>\n “Those with certain chronic conditions, especially kidney disease \u2014 since your kidneys regulate your electrolytes \u2014 high or low blood pressure or heart disease, should consult their doctor before consuming these products, as maintaining fluids and electrolytes within a specific range may be critical for their health,” Braunstein added. <\/p>\n","protected":false},"excerpt":{"rendered":"Sign up for our free Health Check email to receive exclusive analysis on the week in healthGet our…\n","protected":false},"author":2,"featured_media":4107,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[61],"tags":[97,269],"class_list":["post-4106","post","type-post","status-publish","format-standard","has-post-thumbnail","category-nutrition","tag-health","tag-nutrition"],"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/4106","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/comments?post=4106"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/posts\/4106\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media\/4107"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/media?parent=4106"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/categories?post=4106"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/us\/wp-json\/wp\/v2\/tags?post=4106"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}![\"Should](\"https:\/\/www.newsbeep.com\/us\/wp-content\/uploads\/2025\/07\/GettyImages-2220798780.jpeg\")
