Benefits of Contrast Therapy

Contrast therapy involves transitioning the body between hot and cold temperatures to promote a physical response within the body.

The practice has been around for centuries and we're now finally gathering the scientific data to explain what is happening within our bodies, and learning why the benefits are wide-ranging across our physical and mental health.

Stress Reduction

A sauna offers a quiet, tranquil retreat from the world where you can relax and recharge.

Regular sauna use also supports your body’s natural stress regulation processes. Raising your core temperature reduces the levels of cortisol (the ‘stress hormone’) in your system while at the same time releasing feel-good endorphins.

Cardiovascular Function

Using a sauna dilates blood vessels and increases blood flow to the skin, helping regulate blood pressure and improve circulation.

Regular sessions have a direct, positive impact on cardiovascular function and heart health – and the benefits increase the more often you go.

Improved Sleep

Sauna has been shown to improve sleep quality by increasing the production of endorphins reducing levels of cortisol, a stress hormone. The sauna also helps to relax muscles and increase blood flow, which can create a sense of calmness and relaxation. Additionally, the release of sweat during a sauna session can help to detoxify the body and improve overall health, which can also contribute to better sleep.

Reduced Inflammation

Saunas have been shown to have anti-inflammatory effects on the body through scientific studies. The heat from the sauna causes the body to release heat shock proteins, which can help reduce inflammation. Additionally, sauna use has been shown to increase levels of anti-inflammatory cytokines in the body. Regular sauna use has been linked to reduced inflammation in conditions such as rheumatoid arthritis.

Anti-Aging

When you sit in a sauna, your body temperature rises, causing your blood vessels to dilate increasing blood flow to your skin. This blood flow delivers more oxygen and nutrients to your skin cells, to repair damage and promote collagen production. Additionally, the heat from the sauna can help to stimulate the production of heat shock proteins, which protect cells from stress and damage. All of these factors can help to improve the appearance of your skin and slow the aging process.

Body Detoxification

Sauna is an effective method to detoxify the body. As you sit in a sauna, your body temperature increases, leading to sweating. Sweating is a natural way for the body eliminate toxins. The heat also enhances blood circulation, which aids in the removal of toxins from the body. Furthermore, the sauna promotes muscle relaxation, which can alleviate stress and tension. In conclusion, sauna is a beneficial way to detoxify the body and feel rejuvenated.
