HUUM won the world's most prestigious design awards with two products

Estonian design heater manufacturer HUUM OÜ participated in the prestigious international design competition “Red Dot Award” and won a product design award for two products. The prize went to the electric heater CLIFF and the sauna control panel UKU.

The latest electric heater in the product range, CLIFF, is compact and has extremely short safety distances, making it the ideal solution for smaller saunas. The small safety distances are achieved by optimizing the structure and placement of the internal air tunnel. CLIFF is designed by Mihkel Güsson and the engineer is Anti Reiman.

Another award-winning product, UKU sauna controller, makes sauna heating easy and comfortable. Already seven years ago HUUM came out with a remote control, which only now other competitors are catching up with. By using UKU sauna controller it is possible to control the sauna locally, via Wi-Fi network or with a built-in GSM module. Through the latter two it is possible to control the sauna from a mobile application all over the world. UKU is designed by Mihkel Güsson. Maarja Lind, HUUM’s Design Manager, is responsible for further developments in UKU design. The UKU app is designed by Keijo Kraus.

Red Dot CEO Professor Dr. Peter Zec on the laureates

“The winners of the Red Dot Award: Product Design 2021 were particularly impressive this year. The design of their products is excellent, in terms of both the aesthetic and the functionality. It’s not easy to prevail in such a strong field of competitors and to win over our jury. Consequently, I want to congratulate the laureates very sincerely on their success,” said Professor Dr. Peter Zec, founder and CEO of Red Dot.

The Red Dot Award is no stranger to HUUM. In 2015 HUUM’s first electric heater DROP, designed by Mihkel Masso, also received a design award. It is gratifying to note that by 2021 ten Estonian products have won the Red Dot award, three of which belong to HUUM.

The award-winning products can be found in exhibitions, online and in the yearbook

CLIFF and UKU can be seen in the online exhibition on the Red Dot website from 21 June 2021. That date also marks the beginning of the Red Dot Design Week, during which this year’s award winners and HUUM will be celebrated online.

From 22 June 2021, CLIFF and UKU will also be included in the exhibition “Design on Stage” in the Red Dot Design Museum Essen, where all of the award-winning products are showcased. Visitors to the museum can experience the quality of the designs in a space that features contemporary design solutions and historical industrial architecture. The Red Dot Design Yearbook 2021/2022 comes out in August. The publication provides a comprehensive overview of the state of the art and trends in product design.

About the Red Dot Design Award:

In order to appraise the diversity in the field of design in a professional manner, the Red Dot Design Award breaks down into the three disciplines of Red Dot Award: Product Design, Red Dot Award: Brands & Communication Design and Red Dot Award: Design Concept. With more than 18,000 entries, the Red Dot Award is one of the world’s largest design competitions. In 1955, a jury convened for the first time to assess the best designs of the day. In the 1990s, Red Dot CEO Professor Dr. Peter Zec developed the name and brand of the award. Ever since, the sought-after distinction “Red Dot” has been the revered international seal of outstanding design quality. The award winners are presented in the yearbooks, museums and online. More information is available at www.red-dot.de.

Steam like in a traditional sauna

HUUM heaters are built by using very small amounts of metal so that the heat comes mainly from the stones and only very little from the metal. This way we can maximize the good negative ions from the stones, like in traditional saunas, and keep the positive ions from the metal at a minimum. Together with a high stone capacity this is our secret to healthy, mild and long-lasting steam.

Sauna Room

Wall materials and insulating the sauna room

In a sauna with electric heating, all massive heat accumulating wall surfaces (brick, glass brick, rendering etc.) must be insulated to use the electric heater with a regular output.

A Good Sauna Will Help You Fight off Viruses

Regular sauna baths boost the immune system and keep us healthy during the virus-infested winter season. Sauna’s healthy effect can be explained by two things, mucus and heat. A fair warning: the following is based on scientific research.

Some basic facts first. The blanket of mucus in the nasal cavity and paranasal sinuses form the first line of defence against viruses. Despite its nasty name, this watery mucus is highly useful—it catches virus particles and stops them from entering our organism. We then expel the foreign particles and pathogens by sneezing, coughing and blowing our nose, thereby cleaning the blanket of mucus. Every child is thought to use a hanky to cover her nose and mouth when sneezing or coughing to prevent the virus from spreading. And we are all learning how to wear face masks to stop the COVID-19 pandemic for the same reason.

Dry air inhibits mucus regeneration

Most virus particles are caught by the layer of mucus before they can do harm. However, sometimes the air we breathe dries up the watery mucus, making it easy for the viruses to enter the body. Dry air is perfect for different viruses, including the coronavirus which causes the COVID-19 pandemic, rhinovirus and the influenza virus. Human beings feel comfortable if the indoor humidity is between 25%–70%.[1] But if the relative humidity drops below 20%, the blanket of mucus dries up and our defense against viruses is impaired.[2] In consequence, viruses enter our body and we may fall ill.

Sauna to the rescue

The relative humidity in a typical svideoauna is only 10–20%. Yet few people take sauna baths without throwing water on the stove. This activity drastically increases air humidity (up to 80%) and creates perfect conditions for regenerating mucus and repairing tissue. After the layer of mucus is restored in the humid air we are again prepared to fight off viruses—virus particles will be trapped inside the new watery layer on our nasal cavity and paranasal sinuses.

High temperature vs. common cold

Even if some viruses slip through the first line of defence, sauna’s hot air will kill them off quickly. Many viruses do not tolerate hight temperatures. Human rhinoviruses which cause common cold is one such virus. According to different studies, rhinoviruses reproduce in temperatures lower than 33°C (91°F). It is probably for this reason that rhinoviruses cause upper respiratory infections as they cannot survive deep in the human body where temperatures are higher. Spending only 20 minutes at 45°C (113°F) activates our immune system and reduces rhinovirus’ capability to multiply more than 90%.[3] In sum, sauna is less than an ideal place for rhinoviruses as well as many other viruses.

Sauna and COVID-19

Also the coronavirus does not like high temperatures, albeit for a different reason. Coronaviruses are surrounded by an envelope which protects the virus when traveling from one host cell to another. Such viruses are relatively resistant to cold and therefore are more likely to cause sickness in winter months. However, the protective lipid envelope is destroyed if the temperature is held between 55–65°C (131–149°F) for 15–30 minutes.[4] Only one minute will do if the temperature is 80°C (176°F). Human beings can endure such heat, the virus can not.

In addition, coronavirus does not tolerate an alkaline environment. In the intense heat of sauna, our breathing becomes deeper and more frequent. This makes our blood pH levels rise. Different strands of the coronavirus cannot reproduce in such conditions, become inactive or disintegrate complete.[5]

Is it really so simple?

The conclusion seems obvious—taking sauna baths regularly will protect us against viruses. Alas it is not that simple. We have to keep in mind that, even if the sauna thermometer reaches 120°C (248°F), the core temperature of our body rises no more than a few degrees. Yet the virus particles that have already entered into our organism are untouched by the high environmental temperatures and remain intact. Taking sauna baths is not a miracle cure against viruses if we are already sick. Sauna can be used as a preventive measure to boost our immune system, regenerate the mucus blanket in our nasal cavity, and kill off free virus particles in our upper respiratory tracts. But it will not cure us.

Even though in most cases taking sauna baths may be good for us, it is best to avoid sauna if you are already sick. Because our body is weak, it cannot deal with sudden and steep temperature changes. A sick and already weak organism simply cannot take it. We may easily weaken our organism further by exposing our sweaty body to colder temperatures in the antechamber or outside.
