Wants to prove the health benefits of wood in healthcare

Can clear elements of wood in healthcare facilities contribute to faster recovery and increased well-being of patients? In that case, there are great gains to be made, for both people and the economy. In 2021, a research project started at the orthopaedic clinic at Skellefteå Hospital that investigates the connection between health and wood.

Studies at Skellefteå Hospital

Scientifically demonstrating that wood has health benefits is a recurrent ambition in the research community. Yet relatively few studies have been carried out in this area and there is much still to be learnt. There is evidence that heart rate and blood pressure fall when we spend time in the forest and Norwegian studies (Qvale Nyrud, 2015) have shown that the same is true for indoor environments with exposed wood.

A research team at Skellefteå Hospital has had a patient room fitted with pine panelling in order to analyse the impact of wood on patients. The 28 patients included in the study so far have spent their hospital stay in the specially decorated room and had their scores compared with patients hospitalised in an equivalent patient room with no timber cladding.

Pilot project

Bror Sundqvist, Director of the Wood Science and Engineering division at Luleå University of Technology, is leading the pilot project at the orthopaedic clinic in Skellefteå.

“We are analysing whether wood can actually improve recovery in patients. The study focuses on how expanses of wood can reduce stress, fatigue and anxiety, by taking regular measurements of heart rate and blood pressure. All the patients staying in the wood-panelled room wear heart rate monitors and we can also study their sleep patterns. A questionnaire asks them to rate their own well-being, how they perceive the environment and the feeling in the room. The questions are asked without any focus on the wood,” explains Bror.

Interdisciplinary research needed

The results and responses from the different measurements are interpreted by a number of nurses and medical experts in the hospital, who try to identify any differences between patients in the different rooms. So far, the number of patients − the statistical base − is too small to show any clear clinical results. At least 60 patients need to be included in the study before any conclusions can be drawn and Bror anticipates having verified data by the end of 2025.

Hopefully the results of the pilot project in Skellefteå will show the same clear link between wood and health that his Norwegian colleagues demonstrated in previous studies.

“This pilot project was prompted by the results of a similar study conducted at the orthopaedic department in Trondheim in 2015−2016. This indicated that patients in rooms with wood panelling on the walls had shorter stays than patients in rooms without wood panelling, but further multidisciplinary research is needed to verify the role of wood.”

At a conference in 2017, Bror Sundqvist got in touch with Anders Qvale Nyrud, who conducted the Norwegian study, and managed to set up a Swedish version a few years later, in collaboration with Swedish Wood and others.

Beginning of a long knowledge journey

The project has had anything but an easy journey, interrupted by both a pandemic and hospital renovations, but Bror is determined to see the research through to the end − if only to use the results of the pilot project as a basis for future, more comprehensive studies in this area.

Exciting research is going on around the world and Bror hopes to be able to carry out larger studies in the future, in more environments featuring wood, preferably in partnership with other countries and researchers.

“Getting stable funding isn’t easy, but this is a very interesting area of research, with the potential to bring about major societal benefits. We have a lot to learn and it is high time we in Sweden contributed our own insights on how wood can promote better health and faster recovery. Personally, I really believe it does, but it would be great if we could conclusively prove it,” concludes Bror.
