Ice Bath Before Or After Your Workout
As a popular recovery technique, cold water immersion is a staple in the strength and conditioning community. From a physiological perspective, it improves muscle activation and increases body temperature, brown fat, immunity/resilience to cold, insulin sensitivity and catecholamine response. From a psychological standpoint, it promotes mental capacity and stress resistance. However, it’s important to note that the timing of an ice bath is key to its effectiveness. In order to maximise the benefits, it is recommended that a cold plunge be used before or after your workout.
Taking an ice bath before a workout can help to reduce inflammation in the muscles and aid recovery after intense training sessions or competitions. This is because the cold water causes the blood vessels to constrict, which can help to flush out lactic acid and other waste products from the muscles, says HealthFiend. Furthermore, the cold water can also reduce pain signals by numbing the nerves, so it may help to alleviate any post-workout soreness.
Cold immersion can also increase norepinephrine release, which is a neurotransmitter that can promote alertness and enhance concentration. This is because norepinephrine is a stress hormone that’s released in response to exercise, and by stimulating its release, you can prime your brain for a workout.
The most common reason for using an Ice Bath is to reduce muscle soreness and speed up the recovery process after a hard training session. The cold water can cause the blood vessels in the affected area to constrict, which can flush out lactic acid and other waste products and improve circulation, says HealthFiend. It can also reduce the intensity of pain signals by numbing the nerves, and it can also make your muscles feel less sore and tense.
Why Use an Ice Bath Before Or After Your Workout?
However, an ice bath can actually hinder muscle growth if it is used too soon after a workout. The inflammatory response that follows intense training can inhibit muscle growth, and the inflammation can continue for up to 48 hours. It’s therefore best to use an ice bath after your workout, but only up to the neck, and only for 10 minutes.
The type and concentration of ice you use to fill your tub should also be taken into account. If the ice is too cold, it can cause the blood vessels in your skin to contract and limit blood flow, which can lead to an increased feeling of pain. Alternatively, if the ice is too warm, it can cause you to overheat and dehydrate. To avoid these complications, it’s essential to test out the temperature of the ice bath before diving in, and to adjust the amount of ice accordingly.
Ideally, you should immerse yourself in a mixture of 15 degC water and 1 degC ice to get the most beneficial effects. If you’re unsure about how to go about this, seek advice from a qualified healthcare professional. You should always listen to your body, and if it feels uncomfortable at any point, stop the immersion immediately. During the immersion, the cold temperature numbs pain receptors in the body, which can contribute to the reduction of perceived soreness.
The sharp contrast in blood flow between the constriction and dilation phases may also support improved circulation, potentially aiding in muscle recovery and alleviating delayed onset muscle soreness (DOMS). Additionally, ice baths are thought to provide psychological benefits, offering an opportunity to mentally reset, refresh, and build mental toughness.
