The Science of Water Circulation: Why Cold Plunge Pumps Matter in Ice Baths
Many of the best ice plunges and ice baths used by professional athletes include a water pump to agitate the water the bather sits in. The water in an ice bath needs to keep flowing or circulating to ensure that the bath stays at an optimal temperature.
An ice bath that is too warm or cold will not confer any muscle-soothing or relaxation benefits of cold-water therapy. Stagnant or still water tends to warm quickly, especially if a human body enters it.
If you enter an ice bath without a cold plunge pump, the bath will absorb your body heat, and the water will cool within 30 to 60 seconds. The ideal temperature for an ice bath is about 46.4-59°F (8-15°C), and you need to stay in it for about 2 to 5 minutes, so it needs to stay cool for longer than just a minute.
While an expensive spa or treatment center will have water circulation pumps built-in, portable cold plunge pump can be attached to the side of a tub or pod for personal or home use.
A reliable water pump circulates the chilled water in your ice bath and helps maintain it at the ideal temperature. A pump also helps with filtration and sanitation, ensuring that the water in your ice bath remains clean and your bath is sanitary.
Flowing or moving water in an ice bath also has additional therapeutic benefits. Flowing water draws heat from the body more effectively then still water which could lead to a more effective cold water therapy session.
How To Choose The Right Cold Plunge Pump For Your Ice Bath
If you want to use a water pump to increase the effectiveness of your ice bath, you need to choose the right cold plunge pump. One of the most important factors is the pump’s flow rate.
A pump’s flow rate is measured in gallons per hour (GPH). If you use a chiller in your ice bath, pick a pump that matches the chiller’s recommended flow rate range. Check the chiller’s specifications. Most recommend a flow rate of 500-1800 GPH, so a pump with 1000 to 1200 GPH should work nicely.
If you are not using a chiller, the volume of your tub will determine the proper flow rate. Water in your ice bath must be fully automated every thirty minutes. You want a pump with a GPH that is double the capacity of your tube. For example, a 100 gallon tub needs a pump with a 200 GPH flow rate.
Consider the pump’s noise level. A pump that is too loud can be distracting and annoying. Durability and material quality should also be considered, as you want your pump to last. You don’t want to keep buying a new one every few ice baths.
Finally, energy efficiency is another consideration. An energy efficient pump will allow you to enjoy your bath without worrying about what it is doing to your energy bill.
