What is a Sauna & How Does it Work?

A sauna is basically a small establishment or a room, which is equipped with the ability to provide wet and dry seasons. The humidity levels of the room are low, but the temperature is quite high when compared to a steam room. The heating of sauna rooms is done either by pouring water over heated elements like wood, stones and electric heater, or through infrared radiations that heat up charcoal or carbon fibers. The room is usually lined with wood to ensure insulation to maintain the temperature. The bathers sit inside these rooms for around 10 to 15 minutes to get the desired effect of sauna.

  • Scalp Rejuvenation and Healthy Hair as a Benefit of Sauna: Sauna helps in maintaining the shine and health of hair by activating the sebaceous glands present on the scalp. These glands release certain compounds, which help in moisturizing and conditioning of hair. Thus, sauna helps in rejuvenation of scalp.
  • Sauna Helps in Skin Revitalization: Sauna also helps in making skin younger and revitalized as it helps in improving the blood flow in the skin and removal of dead cells. It also activates the secretion of essential oils in the skin that keep the skin young by relaxing the skin, keeping it soft and moist and improving the skin elasticity.

Frequently hydrating oneself is also required as it helps lowering the blood pressure.
