Tisha B'Av lasts only about 25 hours, but preparing for it starts well before the fast actually begins. The days leading up to the fast are the best window to get the body ready, maintain fluid balance, and avoid habits that make the fast harder to get through. Here is what to start doing now.
Start Increasing Water Intake
Don't wait until the night before the fast to drink large amounts of water. The better approach is to maintain steady, sufficient hydration for several days beforehand, so the body enters the fast already well hydrated, lowering the risk of dehydration during the fast itself.
Cut Back on Caffeine Gradually
For those used to starting the day with coffee, and possibly several more cups throughout the day, it helps to begin reducing that intake a few days before the fast. Tapering off gradually can significantly cut down on headaches and withdrawal symptoms during the fast.
Maintain Balanced Nutrition
In the days before the fast, it is best to avoid loading up on fast food, salty snacks, and processed items. Instead, opt for balanced meals with complex carbohydrates, proteins, vegetables, and fruit, a combination that helps the body maintain steady energy reserves.
Don't Skimp on Sleep
Fatigue makes getting through the fast just as hard as hunger or thirst. Where possible, try to get adequate sleep throughout the week so you head into Tisha B'Av well rested after several good nights of sleep.
Plan the Pre-Fast Meal in Advance
It's worth thinking now about what to prepare for the seudah mafseket, the final meal before the fast begins, rather than leaving it to the last minute. A balanced, planned meal is far better than something rushed or excessive right before the fast starts.
Ultimately, preparing for the fast doesn't begin the night before, it begins in the days leading up to it. A few small adjustments during the week can make the fast considerably easier and allow it to pass more calmly and comfortably.
