JAKARTA - Soaking in cold water may sound unpleasant to some people. However, research shows this activity has a significant number of health benefits, ranging from muscle recovery to increased immune system.

Carmen Van Rensburg, a sports physiological expert, explains that cold water therapy has been used for years due to its tangible benefits. Power coach Michael Hamlin added that cold compresses can help reduce pain that arises after intense physical activity.

Therefore, many athletes use an ice bath as part of the recovery process. Research also supports this benefit by showing that cold water therapy is able to relieve pain as a whole.

In addition, cold baths are known to increase body alertness and energy. The spike in the "law-or-run" hormone and norepinephrine neurotransmitter that occurs when the body is exposed to cold water can have a positive effect on focus and energy.

Not only that, this therapy also has a significant impact on blood circulation. Matt Tanneberg, a specialist in strength and consolidation, explains that blood flow that smoothly helps body organs, including the heart, works optimally. It also plays a role in strengthening the immune system.

Lalitha Bhowani-McSorley, a physiotherapist, added that cold water causes blood vessels to narrow, so that blood flow increases to vital organs and body tissues. When the body gets warm again, this process helps increase circulation and oxygenation.

In addition to physiological benefits, McSorley also mentioned that cold water therapy helps reduce stress. Exposure to cold water stimulates the parasimpathic nervous system, which plays a role in reducing stress levels and increasing relaxation. This effect also supports improving sleep quality.

Another benefit that is no less important is the ability of cold water to strengthen the immune system. According to Hamlin, bathing in cold water increases the release of epinephrines and reduces flu symptoms, as evidenced in a study.

Even so, cold water therapy needs to be done carefully. The recommended duration for bathing is usually about three minutes. For beginners, it is important to start with a short duration, such as 10 to 30 seconds, before slowly adding time.

However, risks remain, especially due to drastic changes in blood pressure that can trigger a cold shock response. This is dangerous, because this response can cause prepared reflexs that increase the risk of drowning, especially if the head is below the surface of the water.

Therefore, consulting with health professionals before trying this therapy is highly recommended. With the right understanding, cold water therapy can be a beneficial part of your health routine.
