The Essence of Forests – Celebrating International Day of Forests

Forests: Lifeline for Our Planet

Today, March 21st, marks the International Day of Forests, a global observance established by the United Nations to highlight the essential role forests play in sustaining life on Earth. Covering 31% of the planet’s land area, forests are home to nearly 80% of terrestrial species, serve as the Earth’s carbon sinks, and provide essential materials and livelihoods for millions of people worldwide.

Finland is the most forested country in Europe, with over 75% of its land covered by trees. These forests are not only a source of biodiversity but also contribute significantly to human well-being, climate stability, and sustainable industries. Forests regulate temperatures, purify air, and mitigate climate change by absorbing carbon dioxide. They also provide a sanctuary for mental and physical health, offering spaces for recreation, relaxation, and cultural traditions that have been passed down for generations.

Forests: Finland’s ”Green Gold”

Forests are often called Finland’s ”Green Gold”, and for good reason. Throughout centuries, they have provided livelihoods, economic stability, and well-being to the Finnish people. Unlike many resource-rich nations with vast mineral wealth, Finland’s greatest natural asset has always been its forests. They have shaped the country’s economy, culture, and way of life, supporting industries from timber and paper production to modern sustainable construction and sauna craftsmanship.

Today, forests and forestry remain a major pillar of Finland’s economy, offering jobs, renewable resources, and sustainable materials that support both traditional and modern industries. Responsible forestry ensures that these benefits continue for future generations.

Could Happiness Be Found in the Forest?

Finland has once again been ranked the happiest country in the world, according to the World Happiness Report 2025, for the eighth year in a row. But what makes Finns so content? Naturally, our happiness is built on strong social support, equality, safety, free education, and healthcare. However, many Finns also credit their deep connection to nature as a key part of their well-being.

Could forests be one of the secret ingredients in Finland’s happiness? Spending time in nature allows people to slow down, disconnect from daily stress, and be fully present. Research suggests that nature immersion helps lower stress hormone levels, improve mood, and enhance overall resilience. The ability to step into a peaceful forest, breathe in the crisp air, and experience a moment of tranquility is something many Finns treasure deeply. The concept of Everyman’s Right ensures that everyone, whether local or visitor, can roam freely and benefit from the healing power of forests.

The Importance of Sustainable Forestry

While forests provide countless benefits, their sustainability depends on responsible forestry practices. Finland is a global leader in sustainable forestry, ensuring that trees are harvested at a rate that allows new ones to grow. This balance supports both the environment and the economy.

At Hetki, we deeply respect the forests that provide the raw materials for our saunas. That’s why we use certified Finnish spruce logs and other timber sourced from sustainably managed forests in northern Finland. These trees grow slowly, developing dense, strong, and durable wood – an ideal material for long-lasting saunas.

Sustainably harvested Finnish wood contributes to a circular economy by:

Absorbing CO₂ as trees grow, helping mitigate climate change.
Storing carbon in long-lasting sauna structures.
Replacing carbon-intensive materials like concrete and steel.
Supporting responsible reforestation and biodiversity conservation.

Why Hetki is a Log Sauna – And Why It Matters

The oldest Finnish saunas were log saunas, and Hetki proudly continues this tradition. But why log saunas?

Here are a couple of important reasons for Hetki being a log sauna:

Natural Insulation & Energy Efficiency – Our 88mm thick laminated spruce logs provide superior thermal insulation without synthetic materials, making them more energy-efficient.
Durability & Stability – Thanks to their laminated structure, our logs maintain their shape over time, reducing warping and ensuring longevity.
Moisture Resistance & Breathability – Finnish spruce logs naturally regulate humidity, creating the perfect sauna atmosphere while preventing moisture buildup.
Safety & Health – Coniferous wood has natural antibacterial properties, making it a hygienic and safe choice for sauna construction.
Connection to Nature – Wood is a living material that breathes, absorbs heat evenly, and emits a natural scent that enhances the sauna experience. Wood feels good on the skin and looks unique and beautiful.

Log saunas have been a fundamental part of Finnish culture for centuries, and Hetki is proud to carry this tradition forward. By using the finest Finnish spruce and employing time-honored craftsmanship, we create saunas that offer more than just relaxation – they provide a meaningful connection to nature and Finland’s sauna heritage.

Embracing Forests

As we today celebrate International Day of Forests, and beyond, we encourage everyone to take a moment to appreciate the forests around us.

Also, welcome to Finland to experience our magnificent, rich forests! Where to explore? All across the country!

One great example is Sipoonkorpi National Park (pictured), located right next to our capital, Helsinki. Moreover, Kuusijärvi with its famous traditional smoke saunas sits at the edge of Sipoonkorpi. Together they make the perfect combination for hiking in untouched forests, enjoying the heat of a sauna, and taking a refreshing swim in the lake – whether in summer or through an ice hole in winter. So, welcome to visit Finland and embrace our forests and saunas — two essential sources of happiness!

If you’re planning to invest in an outdoor sauna for your home or retreat, why not choose one that respects and honors the forests? Contact us at Hetki to learn more about our high-quality, genuine Finnish, sustainable, long-lasting log saunas.

Happy International Day of Forests!
