The heat and sweating in a sauna stimulate the sebaceous glands in the skin. These glands produce sebum, which helps to keep the skin moisturised and lubricated. Saunas can help to keep your skin in great shape by stimulating the production of sebum.

When you step into a sauna, your body temperature increases, prompting your blood vessels to dilate. This facilitates improved blood flow throughout your body, enhancing your circulation.

Using saunas can enhance your immune system by raising body temperature, resulting in a simulated fever. Fever is an indication of the immune system's engagement in combating infections, and the increased body temperature aids in the eradication of bacteria and viruses through the stimulation of white blood cells, antibodies, and other disease-fighting agents.

After a workout, your muscles produce lactic acid, which can cause muscle soreness and fatigue. However, infrared saunas can help to remove lactic acid from your muscles and promote faster recovery. The heat from the sauna increases blood flow and circulation, which helps to carry away lactic acid and other toxins. This can help to reduce muscle soreness and improve your overall recovery time.

The process of sweating can offer stress relief. By sweating, your body releases endorphins, hormones that possess mood-enhancing effects. These endorphins can be instrumental in alleviating anxiety and depression, ultimately enhancing your overall mood.

Saunas may improve heart health by making blood vessels more flexible, reducing stiffness in arteries, and helping the body regulate blood pressure.

Saunas help to regulate blood pressure by increasing the production of nitric oxide and by reducing stress.
