Why Proper Hydration is Crucial After a Hot Tub
Many people are unaware that spending time in a hot tub causes the body to lose a considerable amount of fluid through sweating, much like exercise. The body's temperature rises in the warm water, and it sweats to cool itself down. Unlike during a workout, however, the water can mask this perspiration, making it easy to become dehydrated without noticing until symptoms appear. This fluid loss also affects your electrolyte balance, which is essential for nerve and muscle function. Ignoring these signs can lead to feeling fatigued, lightheaded, or developing a headache after your soak.
The Best Drinks for Post-Soak Recovery
Selecting the right beverage is key to a fast and effective recovery. The best options are those that replenish both water and the vital minerals lost through sweating.
Plain Water: The Golden Standard
Plain, cool water is the simplest and most effective way to rehydrate. After a hot tub session, it is recommended to drink approximately 1.5 times the amount of water lost through sweat. To make it more appealing, you can infuse it with fruits like lemon, cucumber, or berries.
Electrolyte-Rich Beverages
These drinks are designed to restore the minerals your body loses during intense sweating. While many commercial sports drinks contain electrolytes, they often come with added sugar. For a healthier option, consider making a homemade version with natural ingredients or opting for a low-sugar brand.
Coconut Water
Often called nature’s sports drink, coconut water contains natural electrolytes, particularly high levels of potassium, which is vital for cellular water balance. It is also low in calories and sugar compared to many fruit juices, making it an excellent choice for replenishing minerals.
Herbal Tea
Herbal teas are a soothing, hydrating, and low-caffeine option for rehydration. Varieties like ginger or lemon balm can help your body recharge without the dehydrating effects of high-caffeine beverages. The warmth of the tea can also be calming, extending the relaxation benefits of your hot tub session.
Milk
Surprisingly, milk can be more hydrating than plain water due to its nutritional content. The combination of lactose, protein, fat, and sodium helps the body retain water and aids in slower rehydration, much like oral rehydration solutions.
Beverages to Avoid After a Hot Tub
Just as important as knowing what to drink is knowing what to avoid. Some beverages can hinder your recovery and pose serious health risks when consumed after a hot soak.
Alcohol
Consuming alcohol before or after a hot tub session is extremely dangerous. It is a diuretic, meaning it increases fluid loss and exacerbates dehydration. Combining alcohol's effects with the heat of the tub can lead to dizziness, impaired judgment, and an increased risk of serious accidents, including drowning. It is safest to wait until after your soak is complete and you have rehydrated properly to enjoy an adult beverage.
Excessive Caffeine
While a moderate cup of herbal tea is fine, drinks high in caffeine like coffee and many sodas have diuretic properties that can increase fluid loss. In a hot, stimulating environment like a hot tub, excessive caffeine can also lead to an undesirable increase in heart rate, counteracting the intended relaxing effect.
High-Sugar Juices and Sodas
Beverages packed with sugar can lead to a quick crash in energy levels and do not provide the necessary electrolytes for proper rehydration. These sugary drinks can also interfere with your body’s ability to absorb water effectively, making them a less-than-ideal choice for post-soak recovery.
Comparing Post-Hot Tub Drinks
| Drink | Key Benefit | Best For | Considerations |
|---|---|---|---|
| Water | Simple, no calories, most efficient rehydration | General rehydration, everyday use | May need electrolytes for heavy sweating |
| Electrolyte Drink | Replaces lost minerals (sodium, potassium) | Intense heat sessions, heavy sweating | High in sugar; choose low-sugar or homemade options |
| Coconut Water | Natural electrolytes, high potassium | Lighter sweat sessions, potassium boost | Low in sodium, may not fully replace losses from heavy sweat |
| Fruit-Infused Water | Flavor boost without excess sugar | Everyday hydration, those who dislike plain water | No significant electrolyte replacement; depends on added fruit |
| Herbal Tea | Calming, low-caffeine hydration | Relaxing after soak, evening use | Ensure it's herbal/non-caffeinated to avoid diuretic effects |

Hydrating Foods Can Also Help
Beyond beverages, you can help your body recover by snacking on hydrating foods. Water-rich fruits like watermelon, honeydew melon, oranges, and strawberries are excellent choices. Vegetables such as cucumbers and leafy greens also contribute to your fluid intake. Having some light, fresh fruits available after your hot tub session complements your rehydration efforts. Eating a light, nutritious snack can also stabilize your blood sugar and energy levels.
Conclusion
Proper rehydration is the final, and most crucial, step of a safe and relaxing hot tub experience. By prioritizing water and electrolyte-rich drinks like coconut water and homemade blends, and actively avoiding dehydrating beverages such as alcohol and excessive caffeine, you can prevent fatigue, headaches, and other symptoms of dehydration.
