Ice Bath Benefits | How Does an Ice Bath Aid Recovery and Performance?

Just the thought of an ice bath can make some people shiver. Others see ice baths as an integral part of recovery and many top training facilities have designated ice bath zones. So, should you be incorporating them into your routine?

What are the benefits of ice baths?

1. Ice baths help the recovery process

When you finish working out, your body pumps oxygen and detoxes. Specifically, it flushes out compounds such as lactic acid, which causes fatigue and soreness. Lactic acid is created when glucose is broken down in the body. The more intense the exercise, the more lactic acid is created.

Ice baths cause your blood vessels to tighten and thus help the body drain lactic acid. They also reduce swelling. Once you’ve left the bath, the blood vessels widen again and let through a stream of “fresh” blood. This blood is packed with oxygen, and so it can quickly set to work reinvigorating the muscles.

2. Limits the inflammatory response

Cooling muscles after exercise can reduce the inflammatory response occurring at the muscle by causing vasoconstriction, thus limiting the volume of blood flow to the muscles. Ultimately this can blunt the effects of DOMS, meaning you will be less likely to experience significant pain and stiffness after training.

3. Decreases the effects of heat and humidity

Having an ice bath prior to an event such as a race in hot and humid conditions can help to boost performance. The human body does not perform at its best when too hot or too cold, so this tactic acts to decrease our core temperature prior to performance, ultimately aiding with homeostasis and body temperature regulation throughout the event, subsequently helping to maximise our performance for longer.

4. Acts as temporary pain relief

The coldness of an ice bath can acutely relieve soreness and pain by simply “making the body feel good” via the release of endorphins. Of course, this is not a long-term tactic to use, but they can be useful if you want some acute relief from muscle soreness!

5. Boosts your metabolism and your immune system

Boosts in metabolism from ice baths are associated with the increased metabolic energy that must be spent to increase and maintain your core temperature. This effect can be sustained for longer periods after cessation. There is also evidence to suggest that ice baths and cold-water therapy can help to boost your immune system, although more research is needed here.

6. Helps you to sleep better

Ice baths help to stimulate a drop in core temperature and facilitate the release of melatonin – both of which are known to contribute to high quality sleep. This method can be particularly effective during hotter months when it is difficult to get cool before bed.

How long should you use an ice bath for recovery?

Experts suggest a 10-minute stay in a chilly tub should do the trick, with approximately 15 minutes being the upper limit. Don’t stay in for more than 15 minutes, as it isn’t advisable to have the blood vessels tightened for so long. You should use an ice bath within 20 minutes of your workout finishing for it to be effective.
