A Brief History of Sauna Therapy

Human has used sauna therapy for centuries. Initially, we had the wood fire saunas; they were later replaced with rocks and heaters to induce heat stress and increase ambient temperatures. The heat stress leads to sweating, increased blood circulation, and some positive health benefits. The health benefits of saunas are immense; thus, you should not wonder when you visit your doctor, and they recommend sauna therapy for your condition.

Sauna therapy has a long history from the traditional wood-fired tent enclosures that used rocks and stones to wooden enclosures with electric hearts and rocks and stones that collect and disperse the heat.

According to some European sauna studies, some traditional saunas yield negative ions when water is poured onto the rocks. These traditional electric saunas are costly both when purchasing and installing. Additionally, they use huge amounts of electricity and require specialized wiring. Besides, the conventional electric saunas need to be heated for at least 30 minutes before you can use them. This means if you use your sauna daily, you spend about $200-$300 each month on electricity bills.

Due to the cost associated with purchasing and installing traditional electric saunas, these types are not common in clubs and gyms. The far infrared sauna has thus become more popular even in homes. The infrared saunas are readily available and more popular, and many companies engage in the manufacture of these saunas in varying sizes. Most of these units come with a floor, walls, and ceiling panels that you can easily screw together to make the sauna. These far infrared saunas can function comfortably on a 110-volt dedicated circuit of 20 amps or higher. With the far-infrared saunas, they come in a variety of wood finishes, since some individuals are chemically sensitive to the traditional cedar smells after the wood heat up.

Is Infrared Heat Safe?

Although most individuals are familiar with the traditional saunas, some individuals may not have adequate information about the infrared saunas, especially their safety.

In simple terms, we can describe infrared saunas as small rooms fitted with infrared heaters. These heaters emit infrared heats that don’t raise the temperatures in the rooms but is directly absorbed into the individual’s body. This model is similar to what happens when you sit in the sunshine; you’ll feel much warmer, although the room temperature remains cool. Therefore, an infrared sauna is a form of a dry sauna that utilizes a heater to offer the beneficial effects of a sauna. On the contrary, in wet saunas, water is poured on hot rocks to produce steam. Typically, the dangers of infrared saunas are similar to those of wet saunas and involve excess heat.

The following are some of the risks that come with the use of infrared saunas:

The main risk of an infrared sauna, just like the wet saunas, comes when you overdo the process. Overheating may lead to severe dehydration and fainting. Dehydration affects your electrolyte balance since you lose lots of electrolytes when you sweat. The case may be worse for the elderly since the sweat glands lose their functions as one age. It’s also essential to note a child’s body temperature rises faster than in adults, therefore if you’re a parent, you should seek the opinion of a pediatrician if you want to take your child to a sauna.

The risk of overheating increases with alcohol intake. Additionally, those on barbiturates, antihistamines, diuretics, and beta-blockers should be cautious about infrared saunas. These drugs affect the ability to sweat and may lead to dehydration. An individual with health disorders such as diabetic neuropathy, Parkinson’s disease, adrenal suppression, and multiple sclerosis may also not have the capacity to handle the heat from the infrared heaters safely.

  • Worsening Eczema

According to a study published in the American Journal of Medicine, sweating in a sauna may lead to increased itching in individuals with eczema. In similar research published in the European Journal of Pediatrics in 1989, over half of the children with Atopic dermatitis suffered worse symptoms in the sauna.

  • Heart disease

Although most individuals with heart conditions can safely use saunas, individuals suffering specific types of heart conditions should avoid using saunas; this is according to a study that was published in the American Journal of Medicine on Feb 1, 2001.
