أسبوع النباتات المنزلية الوطني: الفوائد الصحية للبيوفيليا والنباتات

Bringing nature into our homes and workspaces can immediately make us feel less stressed and anxious¹. In an increasingly stressful, populated, and urbanised world - where most of us live in urban areas² - these so-called biophilic indoor environments are needed more than ever:

What is biophilia?

Biophilia literally translates to 'love of life or living things'. This word was first used by famed psychologist Erich Fromm but was made popular by Harvard University biologist Edward O Wilson, who wrote the book Biophilia in 1984.

The idea is that human's love for and desire to be with nature comes from an inherent, biologically driven need to interact with other forms of life, such as plants and animals.

For instance, Wilson believed that humans love flowers because for many plant species, flowers signal that fruit, a known source of nutrients for early mankind, would be arriving soon. Also, our affection for baby animals suggests that connecting with animals, and protecting the most vulnerable of them, gave early people an evolutionary advantage.

Why does it help, and how does it work?

Nature has been widely shown to benefit mental health and wellbeing, and is simply our proper place in the world, according to Dr Peter James, assistant professor of public and environmental health.

James believes that we can better recover from التوتر and improve our mental health and function in natural settings, because that’s where we are meant to be.

Biophilia works on many levels. Psychotherapist Laura Duester says: "It allows us to connect with the world around us, be more مدروسة, and switch-off from بالقلق or difficult thoughts."

There are many sensory inputs which can be calming and provide pleasure, says Duester, like looking at trees, smelling flowers and hearing birdsong. "Being in the sunlight increases our bodies فيتامين د, and getting outdoors is also fun, such as when we enjoy splashing in puddles, sitting in the sun, or stepping on crunchy leaves."

The benefits of فيتامين د have long been noted. Nicknamed the 'sunshine vitamin, it is made by the skin directly from sunlight, and plays a major role in the normal function of the immune system and in bone, tooth, and muscle health.

"There is lots of research which shows that nature has substantial physical and emotional health benefits," says Duester. "When people experiencing stress spend time in natural environments, they experience more positive emotions and a decreased physiological stress response³".

Research also shows that people who regularly enjoy nature are happier and more satisfied with life and feel less بالاكتئاب and anxious⁴.

What is the best way to get biophilia in your life?

Outdoors

Think in colours green, blue and yellow:

• Spend time in green spaces, like parks or forests.

• Enjoy blue spaces, such as rivers, beaches, or banksides.

• When the yellow sunshine's out, get outdoors, even to just sit in a garden, balcony, or doorstep. But take steps not to burn.

"Use your eyes and ears," says Duester: “Whether it’s bird-watching, growing scented herbs, forest-bathing or hiking in the mountains, find out what works for you and prioritise it. Even if you're walking in a city, try and enjoy urban plants and wildlife."

At home

It's not always possible to get outdoors in nature, but research suggests that we can get similar benefits when we bring nature into our homes.

One study found that filling a room with houseplants and other natural materials, having significant window space showing daylight and a natural view, or both of these things combined can instantly reduce stress and anxiety¹.

Duester also recommends gardening or growing fruit and vegetables at home. "Or indoors, you might enjoy looking at trees through the window, or placing a simple indoor plant on your desk. Even watching nature documentaries and listening to nature soundscapes can be effective."

At Work

In 2019, the World Health Organization (WHO) officially classified workplace الإرهاق - the feeling of exhaustion caused by ongoing stress at work - as an occupational phenomenon⁵.

Given many of us spend around one third of our lives in an office, there's been increasing focus on making the work environment as healthy and attractive as possible.

One study looked at the effects of drab, plant-free working environments over 10 years⁶. The results showed that employees were happier and 15% more productive when workplaces are filled with a few houseplants.

Indoor greenery acts as a natural air purifier, letting everyone in the office breathe a little easier, which allows them to relax better.

We have control over home-offices, but what about shared office spaces? Increasingly, interior designers and architects are turning to nature to create the healthiest workplaces, as Sheela Shukla of Building Design Partnership (BDP) explains:

"The WELL Building Standard™ gives guidance on how many plants to use in an area, and other ways to integrate nature. For example, we consider indoor planting, calming colours, textures, shapes, forms, imagery, sounds, lighting, and views to external areas.

"An Urban Greening Factor, such as that in the London Plan, also evaluates and quantifies the amount and quality of natural, healthy greening measures in offices."
