Understanding Cold Water Plunging
Cold water plunging, also known as cold water therapy, has become an increasingly popular way to aid post-workout recovery, provide mental clarity, and improve health. But to gain the most benefits, it's important to understand what water temperature is best for a cold plunge.
Defining a Cold Plunge
A cold plunge refers to briefly immersing the body in cold water for health or therapeutic purposes. This cold-water immersion causes the blood vessels near the skin to constrict while deeper vessels dilate. As a result, blood moves inward to protect the vital organs and supply them with freshly oxygenated blood.
The Benefits of Cold Water Plunging
Research shows that brief cold water immersion offers many potential benefits including:
- Reducing muscle soreness and fatigue
- Decreasing inflammation
- Increasing circulation
- Boosting mood through norepinephrine release
- Promoting weight loss by burning calories to warm the body
Taking an ice bath after intense exercise may help speed up muscle recovery so you're ready for your next workout. The cold therapy causes vasoconstriction and vasodilation that flushes fresh nutrient-rich blood through the body to heal damaged muscle tissue.
Choosing the Right Water Temperature
So what's the best temperature for a therapeutic plunge? Research shows water between 50 and 59°F (10 and 15°C) is ideal. This cold water triggers the desired constriction and blood flow without being too uncomfortable.
The 50-59°F Water Range Explained
Water from 50-59°F seems to optimize the benefits of cold water therapy while minimizing the intense pain from near-freezing water. Let's break it down:
- 50°F (10°C) is very cold but tolerable for most people
- 55°F (13°C) elicits a moderate cold shock response
- 59°F (15°C) is chilling but less extreme
You may need to start with 59°F and work your way down to 50°F as your body acclimates. Pay attention to how long you can tolerate colder temperatures before needing to get out.
Going Below 50°F
Some cold therapy enthusiasts use ice baths with water as cold as 35 to 40°F. However, spending over a minute in water below 50°F starts to sharply increase risk of hypothermia and frostbite.
If you want to plunge below 50°F, limit time in the ice bath to 30-90 seconds. This avoids thermal shock while still stimulating beneficial vascular system effects. Always check with your doctor before using extreme cold therapy.
Other Cold Water Therapy Options
Full body ice baths aren't the only way to reap cold water benefits. Other methods like cold showers, facials, and cryotherapy pools allow more precise temperate exposure.
Cold Showers
Taking a brief 30-90 second cold rinse at the end of a warm shower triggers a similar systemic cold shock, just localized to skin and tissues. Over time, regularly braving a cold finish may improve circulation, mood, and brown fat levels.
Cold Facials
Splashing very cold water on just the face neck and upper chest stimulates the vagus nerve. This can lower heart rate, blood pressure, and anxiety. The easiest way to try this is to fill a bowl with cold water and ice cubes then immerse your face for as long as you can stand.
Cryotherapy Pools
Cryotherapy pools maintain very cold water year-round, usually from 35-50°F. This allows athletes to immerse themselves up to the next for cyclic cold exposure. Cryotherapy pools offer more consistent and measurable cold immersion than ice baths.
Safety Tips for Cold Water Plunging
While stimulating, ice baths do carry some risk if proper precautions aren't taken:
- Get medical clearance, especially if you have circulation issues or heart problems
- Never plunge into cold water alone - have a spotter present
- Avoid alcohol or medications before cold water therapy
- Start slowly and gradually work your way down to colder water temperatures
- Pay attention to signals to get out like intense gasping, difficulty breathing, confusion, muscle cramping etc.
As with any therapy, work within your limits, and stop cold water immersion if you feel something isn't right. When done correctly, brief 50-59°F plunges can safely enhance health and speed up workout recovery.
