Fast Hydration

I have always found fasting on Tishah B’Av to be particularly harder than other fast days in the Jewish calendar. Between the heat of the summer, the emotional grief of the day, and the length of the long fast, I have had to become strategic about hydration and what is served beforehand.

It was not until a few years ago that I started serving watermelon before and after the fast. Watermelon is a natural hydration powerhouse. It is 92% water and provides essential electrolytes like potassium and magnesium, alongside natural sugars that help your body absorb fluids faster. Potassium regulates fluid balance and supports muscle/nerve function. Magnesium aids in muscle recovery, heart health, and blood sugar regulation. Watermelon also contains vitamins C and A, which help promote immune health, tissue repair, and hydration absorption. This makes it a natural go-to in both fast preparation and recovery (as well as post workouts!).

Several years ago, watermelon feta salads became a big trend. Many variations abound and they are all deliciously refreshing. The central ingredients are simply watermelon, feta, fresh mint, and lime—all of which are particularly helpful for a fast day. Adding feta lends sodium, which contributes to muscle contraction, fluid balance, and nerve function, as well as spurs on drinking extra water. Lime juice boosts the total amount of vitamin C as well. If you are feeling adventurous, feel free to throw in some shaved red onion and red pepper flakes for savory elements, and finish with a good drizzle of olive oil.

Not a feta person? You can gain the same electrolyte benefits in drink form by blending two cups of diced watermelon, the juice of one lime, one cup of coconut water, a handful of fresh mint leaves, and a generous pinch of Celtic sea salt for extra sodium. Add ice for a slushier effect.

Body and soul, the purpose of a fast day is to cleanse and purify—both on an individual and national level. With these healthful tips in mind, I wish you an easy and meaningful fast. May this be our last Tishah B’Av in mourning. nNaomi Ross is a cooking instructor and food writer based in Woodmere, NY.
