Restorative Experiences in New Wood-Based Accommodations: A Post-Occupancy Study

We spend the vast majority of our lives inside buildings, yet we rarely stop to consider how the walls, floors, and air around us shape our mental and physical state. This question sits at the heart of environmental psychology, a field dedicated to understanding the relationship between people and their surroundings. For decades, researchers have explored the idea of "restorative environments"—places that help us recover from mental fatigue and stress. While nature has long been known to offer this kind of renewal, scientists are increasingly asking whether the materials we use to build our homes and offices can provide similar benefits. Wood, in particular, has captured the imagination of designers and researchers alike. It is not just a structural material; it is often perceived as warm, natural, and healthy. The prevailing theory suggests that bringing natural elements indoors, a concept known as biophilic design, can lower stress and improve our sense of well-being. However, while the idea sounds promising, proving exactly how a wooden room makes a person feel requires more than just good intentions; it demands careful observation of real people living in real spaces.

In 2024, a team of researchers from the University of Helsinki and InnoRenew CoE put these ideas to the test in a quiet corner of Finland. They focused on the Hyytiälä Forest Station, an international hub for climate and forest research nestled among forests, peatlands, and lakes. The station had recently opened a new set of accommodation buildings constructed almost entirely from massive wood. These were not just temporary shelters; they were designed with sustainability and a connection to nature as top priorities, featuring wood on most interior surfaces. The researchers invited the people staying there—mostly scientists, students, and professionals attending seminars—to fill out a survey after their stay. The goal was simple but profound: to understand how these wooden rooms affected the guests' sleep, stress levels, and overall satisfaction, and to see if a new way of measuring these feelings could be developed for future use.

The study gathered responses from 81 visitors. Instead of relying on complex sensors to measure air or temperature, the researchers asked the guests to describe their own experiences. They wanted to know if the guests felt the rooms were safe, cozy, and eco-friendly, and how these feelings compared to what the guests imagined their ideal room would look like. The researchers also developed a new survey tool to see if it could reliably capture these nuances. They found that the tool worked well, producing consistent results across different groups of visitors, though they noted that the questionnaire could be simplified for future use.

When the researchers analyzed the answers, a clear picture emerged. The most significant factor driving a guest's satisfaction was not the view outside or the proximity to a lake, but the feeling of the room itself. Specifically, guests who rated the room as "eco-friendly and cozy" were the most satisfied. This feeling was tied to the presence of wood, the warmth of the materials, and the overall aesthetic. Another important factor was the sense of safety and health, which included good air quality and a feeling of security. Interestingly, the study found that while the surrounding nature was beautiful, it did not directly predict how well a guest slept or how satisfied they were with their stay, though there was suggestive evidence that the general atmosphere of the location was associated with better sleep quality. Instead, a guest's general sense of well-being and their stress levels were the strongest indicators of how well they slept.

The researchers also looked at the gap between what guests wanted and what they got. They found that guests generally felt the new wooden rooms were better than their "ideal" accommodation in terms of newness, beautiful materials, and environmental friendliness. However, there was a notable trade-off. While the large windows offered stunning views and plenty of natural light, many guests felt a tension between this openness and their need for privacy. Some noted that they had to keep curtains drawn to feel secure, which meant they missed out on waking up to natural light. This suggests that in the pursuit of a biophilic design that connects us to nature, architects must also provide guests with the control to adjust their environment to feel safe and private.

One of the most intriguing findings concerned the relationship between stress and the wooden environment. The data showed a strong link between the "eco-friendly and cozy" rating and stress levels, but the direction of this link was complex. It appeared that people who were already stressed might have found the wooden rooms particularly comforting, rating them higher because they needed that comfort. This does not mean the wood caused the stress, but rather that the environment responded to the human need for restoration. The study also ruled out several assumptions. For instance, the researchers found that a person's background—whether they were a student, a professional, or had a history with forestry or construction—did not change how they felt about the rooms. Similarly, the specific details of the neighborhood, like access to shops or social areas, had little impact on satisfaction compared to the quality of the room itself, though there was weak evidence that access to essential services might play a minor role.

Ultimately, this study confirms that the materials we choose for our buildings matter. The wooden accommodations at the forest station provided a space where guests felt safe, healthy, and satisfied, largely because the environment felt warm and natural. The research suggests that while we cannot simply build our way to perfect sleep or zero stress, creating spaces that feel eco-friendly and cozy can be a powerful tool for improving how people feel. The study also highlighted the importance of balance; a room can be beautiful and full of light, but if it leaves a person feeling exposed, the benefits are lost. By listening to the people who actually live in these spaces, the researchers have provided a clearer map for designing buildings that do more than just shelter us—they can help us restore ourselves.
