Ice Bath
Ice bath, which involves exposing the body surface to low - temperature water (usually below 15 degrees Celsius), is also known as cold water immersion and is actually a form of cryotherapy. One should immerse in cold water up to the chest and persist for 10 - 15 minutes. Many professional sports training centers are equipped with special ice pools or ice tubs.
The principles of ice - water bath include: causing blood vessels to constrict. When the body is immersed in cold water, blood vessels contract. After the ice bath, the blood vessels dilate, which accelerates blood circulation in the body, expels waste generated from exercise and metabolism, and transports nutrients and oxygen to tissues such as muscles. This helps reduce inflammation and swelling, lowers muscle temperature, slows down the metabolic reaction of cell damage, and slows down the nerve transmission speed, achieving muscle relaxation and creating a numbing and pain - relieving sensation in the body.
The first time one takes an ice bath, it can cause intense discomfort. However, after persisting for 5 - 10 minutes, both the body and mind can be relaxed.
Regarding the use of ice baths, an alternative is to alternate between cold and hot water. First, immerse in cold water for 10 - 15 minutes, and then in hot water for 10 - 15 minutes. Through this hot - cold stimulation of the body, the blood circulation speed will be even faster.
Although in the long run, the expansion and contraction of blood vessels during ice baths can enhance blood vessel elasticity, prevent hardening of the arteries and the resulting coronary heart disease and hypertension, and help prevent cardiovascular and cerebrovascular diseases, it is not suitable for everyone. For example, people with hypertension and cardiovascular diseases need to pay special attention:
After patients with hypertension are exposed to an ice bath, their blood vessels will contract rapidly, and a large amount of blood will flow back to the internal organs, increasing the original high blood pressure. In severe cases, it can lead to cerebral vascular rupture, bleeding, stroke, coma, or even death.
For patients with coronary heart disease, the coronary arteries are narrowed. The stimulation of an ice bath can cause the coronary arteries to contract, aggravating myocardial ischemia, leading to angina pectoris, or even acute myocardial infarction or sudden death. In addition, there are certain potential risks for patients with hypothermia to take an ice bath.
The influence of ice baths
Cold application on the body surface triggers certain physiological responses, such as decreased metabolic rate, local swelling, reduced nerve conduction velocity, muscle spasms, and local anesthesia. At different temperatures, when the entire body except for the head is immersed in water, various indicators of the body undergo changes (compared to normal temperature), including metabolic rate (MR), rectal temperature (TRE), heart rate (HR), central arterial systolic blood pressure (SBP), central arterial diastolic blood pressure (DBP), plasma renin activity (PRA), plasma cortisol levels (PCR), plasma aldosterone concentration (PAC), and diuresis. The concentration of cortisol in the blood is not affected by different water temperatures, and there is no correlation between rectal temperature changes and hormonal changes. Physiological changes in the human body are controlled by the body's own regulatory systems, and the response to cold water is mainly due to increased sympathetic nervous system activity. Regular ice baths can reduce stress, fatigue, and feelings of depression; increase vitality; and alleviate pain, including pain caused by conditions such as rheumatism, fibromyalgia, and asthma.

Benefits of ice bath
-
Relieve inflammation and swelling
By taking an ice bath, the cold temperature narrows your blood vessels. This slows down the circulation of blood to your muscles, which can ease the redness and puffiness. And research demonstrates that the cold-cure technique decreases post-workout inflammation more efficiently than other options like compression socks.
-
Ease sore muscles
A cold bath could alleviate your sore muscles. The exact process is unknown to scientists. But lessened redness and slower nerve signals could cause less distress. Cold water might also reduce how much pain or soreness you feel.
-
Aids exercise recovery
After an ice bath, your blood vessels widen, or resume their normal size, boosting blood flow. The nutrient-filled blood that flows to your muscles may help eliminate the metabolic waste that builds up during exercise. That’s another advantage of using ice baths for post-workout recovery.
-
Lowers core body temperature
Taking ice baths can reduce your heat when you’re overheated. One investigation revealed that submerging yourself in cold water for slightly under 10 minutes drops your central body temperature after working out. By cooling down after you perspire a lot, you can avoid heat stroke and heat exhaustion.
-
Strengthen immunity
According to some research, ice baths may boost your immune system health. In a small study, people who followed cold water immersion, deep breathing, and meditation had less indications of bacterial infection than those who didn’t.
-
Improves mental health
Ice baths might be good for your mental health too. Exposing your body to cold water triggers a stress response and activates the nervous system. These changes can improve your mood and help you adapt to stress over time.

Precautions
- Degree of DOMS (Delayed - Onset Muscle Soreness)
- Concentration of blood indicators related to cell damage (Creatine Kinase)
- Muscle explosive power (Power)
- Muscle strength (Strength)
The results showed that although ice - water immersion had no significant effect on strength recovery, it could significantly reduce muscle soreness, the degree of cell damage, and assist in the recovery of explosive power that persisted for 96 hours after exercise, which might be helpful for short - term recovery and athletic performance.
