4 min read

Using an infrared sauna can cause a significant loss of fluids and essential minerals through sweating. Knowing what should I eat before an infrared sauna is key to maximizing its benefits, preventing discomfort, and staying properly hydrated during your session.

Quick Summary

Prepare your body for an infrared sauna session by focusing on light, easily digestible snacks and ample hydration. Discover why avoiding heavy meals and dehydrating beverages is crucial to prevent discomfort and maximize the detoxification process.

Key Points

  • Timing Matters: Eat a light snack 90-120 minutes before your session to avoid digestive strain and discomfort.

  • Prioritize Hydration: Drink 16-20 ounces of water 30-60 minutes before you start, and have more water available during the session.

  • Choose Light Snacks: Opt for easily digestible foods like fruits, yogurt, or a handful of nuts to provide energy without burdening digestion.

  • Replenish Electrolytes: Consider a natural electrolyte-rich drink like coconut water, especially if you plan to sweat a lot.

  • Avoid Heavy and Dehydrating Items: Stay away from large, greasy meals, alcohol, and caffeine, as these can hinder your body's ability to regulate heat and cause dehydration.

Understanding the 'Why' Behind Pre-Sauna Nutrition

When preparing for an infrared sauna session, your nutrition and hydration choices are not trivial; they are foundational to a safe and effective experience. The body's energy is naturally diverted to the digestive system to process food. Simultaneously, a sauna session increases your heart rate and redirects blood flow to the skin to facilitate sweating and cool the body. When these two processes compete, especially after a heavy meal, you can experience discomfort, nausea, or dizziness. By eating light and hydrating effectively, you empower your body to focus its energy on detoxification and heat regulation, maximizing the therapeutic benefits of the sauna.

The Importance of Optimal Hydration

Proper hydration is the most critical element of your pre-sauna routine. Saunas induce heavy sweating, which leads to a loss of not just water but also vital electrolytes like sodium, potassium, and magnesium. Failing to replenish these can lead to dehydration, muscle cramps, fatigue, and a feeling of lightheadedness. Preloading with water and electrolytes primes your body for the session, ensures more efficient sweating, and helps to maintain stable blood pressure and energy levels.

What to Eat Before an Infrared Sauna

For best results, aim to have a small, easily digestible snack about 1.5 to 2 hours before your session. This gives your body time to begin digestion without diverting too much energy from the sauna process. Focusing on water-rich and nutrient-dense options is the ideal strategy.

  • Fruits: Water-rich fruits like watermelon, oranges, and cucumber slices are excellent choices. A banana is also a great option to replenish potassium.
  • Yogurt or Cottage Cheese: These provide a light source of protein and can be paired with berries for extra nutrients.
  • Nuts and Seeds: A small handful of almonds, walnuts, or pumpkin seeds can provide a boost of healthy fats and protein without feeling heavy.
  • Smoothies: A simple smoothie with coconut water, a banana, and a handful of spinach is an easily digestible way to get both hydration and nutrients.

What to Drink for Optimal Preparation

Hydration isn't just about water. While filtered water is your best friend, consider these other options to enhance your pre-sauna prep.

  • Filtered Water: Drink at least 16–20 ounces of water about 30–60 minutes before your session to get a head start on hydration.
  • Coconut Water: Naturally rich in potassium and other electrolytes, coconut water is an excellent choice for replenishing lost minerals.
  • Herbal Tea: A warm cup of herbal tea like green tea or chamomile can be soothing and contribute to your fluid intake without the dehydrating effects of caffeine.
  • Electrolyte-Enhanced Water: For those who sweat heavily, a low-sugar electrolyte drink or tablet can be beneficial, especially after a workout.

The Foods and Drinks to Avoid Before an Infrared Sauna

Just as important as knowing what to consume is knowing what to skip. Certain foods and beverages can negatively impact your comfort and the effectiveness of your session.

  • Heavy, Greasy Meals: Foods high in fat, heavy pasta dishes, or large portions of meat require significant digestive effort and can lead to nausea and sluggishness.
  • Caffeine: Drinks like coffee and energy drinks are diuretics and can accelerate dehydration, making your sauna session less comfortable.
  • Alcohol: Alcohol is a known dehydrating agent and can impair judgment and the body's cooling mechanisms, making it dangerous to consume before a sauna.
  • Sugary Drinks: High-sugar juices and sodas can cause blood sugar spikes and crashes, and don't provide the same quality of hydration as water or electrolyte-rich drinks.

  1. Hydrate Early and Often: Begin drinking plenty of water several hours before your session. Sip 16-20 ounces about an hour beforehand.
  2. Time Your Meal: Eat a light snack 90-120 minutes before entering the sauna. This allows for partial digestion.
