Beat the Heat: Water and Sports Drinks for Hydration

Article By: The Rutgers Farm Health and Safety Working Group: Kate Brown, Michelle Infante-Casella, Stephen Komar and William Bamka

When it comes to hydration, the U.S. National Academies of Sciences, Engineering, and Medicine recommends an adequate daily fluid intake of about 15.5 cups (3.7 liters) of fluids a day for men and about 11.5 cups (2.7 liters) of fluids a day for women. Even with this guidance, the amount varies from person to person. Also, when temperatures are hotter and when workloads increase so should drinking water, to prevent dehydration and to help maintain the proper body temperature especially when sweating.

Regular intake of water throughout the day and during the evening, at recommended amounts may help prevent a person from becoming excessively thirsty and also prevent dehydration. The choice of drinking sports drinks that contain electrolytes may be considered when a person’s activities dramatically increase, when they excessively sweat, if they show signs of dehydration, and/or heat stress.

Most sports drinks are designed to replenish glucose, fluids, and electrolytes (sodium, potassium, magnesium, calcium) lost during strenuous exercise or heavy workloads. Sports drinks may contain carbohydrates in the form of sugar, usually glucose, high-fructose corn syrup, or sucrose. Some contain no sugar and are “sweetened” instead with low-calorie sweeteners. The amounts of sugar and electrolytes in sports drinks are intended to allow for quick hydration and absorption.

It is important to note, persons with diabetes should be mindful of not intaking amounts of sports drinks that are high in sugar that could raise blood sugar to unhealthy levels. Additionally, persons with high blood pressure should be mindful when drinking sports drinks that are high in sodium – most are. Persons who eat a healthy diet should have enough glucose and electrolytes to maintain their health, even during extra activities and with proper water intake. Some studies show drinking too many sports drinks, especially when not performing vigorous exercise, can increase the risk of overweight/obesity and other health issues such as type 2 diabetes, cardiovascular disease, gout and the risk of dental cavities.

Water is the best choice to stay hydrated and it is the responsibility of each individual person to be sure they drink enough water to maintain their proper health.

Don’t Let Your Guard Down With Farm Worker Health

The COVID-19 pandemic highlighted the critical and essential role of farm labor in getting food from farm to plate. However, health concerns should not stop with a negative COVID test or vaccine, especially if an employee or family member is exhibiting any of the ‘flu-like’ symptoms that are associated with corona virus.

From the Vermont Law School Center for Agriculture and Food Systems (CAFS) – “The CAFS launched the Food System Worker Law and Policy Project in 2021 with research focused on farmworkers, who—despite forming the backbone of a trillion-dollar industry in the U.S.—face a level of occupational risk unrivaled by most workers. From repeated exposure to pesticides and extreme heat, …. ” Their newly published “report titled “Essentially Unprotected: A Focus on Farmworker Health Laws and Policies Addressing Pesticide Exposure and Heat-Related illness,” … May 2021, provides an overview of the findings as well as policy recommendations that are urgently needed to protect farmworkers.”

Typically not seen until July, we’ve already had 3 heat waves beginning in May that expose workers to a number of potential health risks that may present very similar symptoms and can be equally health, and even life, threatening. Published studies from the Rutgers Institute of Earth, Ocean, and Atmospheric Sciences suggest growing numbers of people worldwide are at risk of heat stress and related complications, including farmers and ag laborers working in high heat and humid conditions. Last year, OSHA-NIOSH released a Heat Index App (in English and Spanish at the Apple App Store or Google Play) featuring:

  • A visual indicator of the current heat index and associated risk levels specific to your current geographical location
  • Precautionary recommendations specific to heat index-associated risk levels
  • An interactive, hourly forecast of heat index values, risk level, and recommendations for planning outdoor work activities in advance
  • Editable location, temperature, and humidity controls for calculation of variable conditions
  • Signs and symptoms and first aid information for heat-related illnesses

For more information about safety while working in the heat, see OSHA’s heat illness webpage, including online guidance about using the heat index to protect workers.

In addition to heat stress, harvesting and other activities along field edges, including going into the woods instead of using a portable bathroom facilities, create a high risk for tick bites which can also carry a number of diseases, many as or more debilitating than Lyme disease. It is critical for your employees’ health and well-being to get proper diagnosis and treatment for all of these ailments. This table illustrates how many tick-born diseases, as well as heat stress, all have potential symptoms very similar to those of COVID-19. Each is linked to additional resources at the CDC. In many cases, it may be the ‘other symptoms’ that may be unique to each disease and assist a medical practitioner with correct identification and lead to better verification with further testing.

Communicating the Value of COVID-19 Vaccines With Your Farm Employees

CDC COVID-19 Vaccine Posters available in multiple languages – “Vaccines (shots) are one of the tools we have to fight the COVID-19 pandemic.”

In an effort to increase participation in the COVID-19 vaccination program among farm workers, the Centers for Disease Control (CDC), through the national Extension Foundation, is working with Cooperative Extension across the country to help spread the word about the importance of getting vaccinated. Rutgers Cooperative Extension Director Brian Schilling has enlisted a team of County Agents and Specialists to answer the call from the CDC to participate in this EXCITE program. Through a variety of communications channels we will be providing informational posters and other educational materials in several appropriate languages that you can hand out or post in locations where your workers can easily read them (like on or near your Worker Protections Standards bulletin boards or in your labor camps).

“Vaccines (shots) are one of the tools we have to fight the COVID-19 pandemic” posters from the CDC are now available on the COVID-19 page of the Rutgers NJAES On-Farm Food Safety website <https://onfarmfoodsafety.rutgers.edu/covid-19-information/> with the direct links to these multiple language editions:

You can also share this Spanish language video <https://wecandothis.hhs.gov/un-rayo-de-esperanza> from the US Dept. of Health and Human Services with your workers to help explain where they can get more information about COVID-19 vaccines. There are several other informational videos available at https://wecandothis.hhs.gov/filter/format/Video, as well as posters/fliers from https://wecandothis.hhs.gov/filter/format/Poster%20%E2%80%93%20Flyer (mostly English), and factsheets at https://wecandothis.hhs.gov/filter/format/Fact%20Sheet.
