Natural Energy

Each person has their own way of getting up and going; some prefer double shots of espresso, a brief exercise routine, or other methods. If you want to jumpstart your day or get a quick energy boost in the afternoon, trying a cold plunge could be a solution worth considering. Cold plunging has become a popular option for those seeking an alternative way to increase their daily vitality.

Recovery & Performance

The advantages of cold plunging go beyond the psychological and physiological effects on your body. In the field of sports medicine, cold water therapy has been employed for several years to facilitate the recuperation of muscles and reduce inflammation following physical activity.


Research has demonstrated that cold plunging can elevate your baseline levels of dopamine, a molecule in our brain and body that is associated with motivation. Dr. Andrew Huberman has suggested that dopamine can improve our concentration and decrease the level of effort required to act on our particular objectives.

Elevated Mood

For quite some time, scientists have recognized the relationship between hormone levels and our daily energy. In particular, there is substantial evidence indicating that hormonal imbalances can lead to depression, suggesting that taking a cold plunge could potentially alleviate symptoms of depression and enhance overall mood.

Stress Relief

Research has demonstrated that cold water therapy can be an effective adjunct therapy for reducing stress by lowering levels of the stress hormone cortisol. According to a study, consistent cold showers and ice baths have helped to alleviate anxiety and enhance the mood of participants.

Pain Relief

Studies indicate that taking regular ice baths can result in a significant increase of up to 5 times in the levels of norepinephrine. This particular neurotransmitter has been found to have powerful anti-inflammatory properties and can assist in managing chronic pain.

Improved Sleep

Taking a plunge in cold water activates the autonomic nervous system in your body, which is comprised of a network of vessels and nerves that are divided into two parts regulating your stress response. By learning to manage your stress response, you may also discover an improvement in your ability to relax and sleep.
