Placing them strategically in spaces that feel drab and empty bring life to dead spaces in your home. According to various studies, having plants around are therapeutic. They help us manage stress and focus our energy positively.

We spend more time indoors because of our lifestyle today. This is especially true for city folk or people who live in urbanity. City life outdoors isn’t as green as we’d expect it to be, which in turn lessens our interaction with nature. We’re not just talking about lush trees, and a variety of plants, but this also includes clean and fresh air, and bright blue skies. To compensate for this lack, a lot of people who live in the city have a few potted plants in their homes.

So, how do indoor plants make you happier? According to the researches, the green foliage and blooms trigger happiness and improve moods. Billions of neural pathways respond well with the sight of plants, informing our brain that we are indeed elated to see nature’s wonders in our living spaces. Plants are said to:

Improve Healing

Plants are placed in hospital recovery rooms, patients may be provided with a garden view, or by the very least they are allowed to keep flowers in their rooms because they have been proven to boost the body’s healing properties.

People who are confined in small office spaces and have no access to any greenery have the tendency to feel sick more often. Companies that actually have plants within working spaces have a lower absenteeism rate. This is because plants are able to:

  • Reduce Stress
  • Lower Blood Pressure
  • Boost Immunity
  • Improve Sleep

At the end of the day, having a plant around is an inexpensive option you can have for a healthier space.

Enhance Performance and Increase Energy

Generally, plants improve the state of mind which increases vitality too. Indoor areas that have plants and other natural elements promote positivity, which make people more active. Plants stimulate the mind and is definitely one way to boost energy especially when you’re confined in a small space.

In a way, having plants around your workspace is cost effective. For just a little amount of money you can increase your productivity. Libraries, offices, and schools should have indoor plants around.

Helps You Relax

When we are closer to nature, we feel more relaxed. This is the very reason why when we go on vacation we tend to visit beaches, forests, mountains, and such to get away from the hustle and bustle of the city life. Being able to see the blue sky, smell nature, and see greeneries can definitely relax your eyes and your mind. By imitating the greenery we see in nature in our indoor spaces, we are able to apply the same principle and promote relaxation at home. The more we are relaxed, the less stress we feel, the more productive we become at the end of the day. It’s this kind of positive chain reaction we need to promote wellness in ourselves.

Improves Memory and Focus

Aromatic plants such as rosemary, have been proven to enhance memory through our sense of smell. Likewise, other plants help us concentrate better through its mere presence. According to a study conducted in the the University of Michigan, around 20% of memory retention is improved in individuals that are surrounded by plant life. This positively affects our cognitive skills and learning capabilities. All this by just having plants within your line of vision.

Absorbs Noise

Living in the city can be noisy. With cars constantly passing through, construction of new infrastructures continuously happening, and congestion of people in a single area, homeowners are always looking for a way to eliminate the noise within their living space. Even small amounts of noise, can cause a lot of stress. By having plants in your home, you can eliminate background noise. The leaves of the plants are great at absorbing sound and diffract background noise. The bigger the leaves, the more effective.

It all boils down to how our brain interprets what we see, smell, and feel into a positive cognitive reaction. With plants surrounding our home and even indoors, we are able to improve our mood altogether and essentially feel happy.

Statistics on Mental Health

Mental illness is a serious matter that needs to be addressed appropriately by every nation. In the US alone, there are approximately 1 in 5 adults that suffer from a serious mental illness that would require intensive treatment. There are even more people who are simply undiagnosed for these illnesses, and would not know how to manage it. With this statistic alone, we should be vigilant about our own mental health and learn to control how our brain interprets stress.

As we mentioned, most people would prefer to take the less invasive approach in treating themselves, be it anxiety or episodes of depression. Thankfully, plants are effective in improving the overall mood of a person. Those with anxiety, depression, and overwhelming stress would just need to surround themselves with plant life to feel better. Of course, it would still be the best to seek professional counsel regarding treatment. Having plants is just an added precaution you can take to improve mental health.

The presence of plants around is not only a form of psychological therapy, there is a lot of science that happens and it has been studied intensively by various universities and organizations.

What is Plant Therapy?

Yes, there is such a thing as plant therapy. This form of therapy is also known as horticulture therapy. The practice in using plants to calm the senses dates back to almost 20 centuries ago. In fact, the ancient Egyptians used “walks in the garden” to treat patients diagnosed with some form of mental illness, and it had been deemed effective.

The hospitals in the middle ages would have a garden space that would allow patients to stroll through. It has been noted that most patients that were exposed to nature during the time of healing have a better disposition, and are able to heal faster compared to those that prefer to sit in their hospital rooms all day. The faster they heal, the more effective the treatment is.

Eventually, the western world began to use plant therapy technique as a means to treat patients with mental health concerns and developmental disabilities.  In 1817, the Friends Hospital, formerly known as the Asylum for Persons Deprived of Reason developed the surrounding land with landscaping and easy-to-access pathways to help patients get better with plant-based interactions. The same hospital built the first greenhouse that was actually used in therapy. The plant therapy method in this hospital has been quite effective, and has influenced other neighboring hospitals to practice the same technique.

During the war era, both World War I and World War II, soldiers that were undergoing physical and occupational therapy to improve the function of their injured limbs were asked to work in gardens. It was noted that they were able to increase mental function, in addition, to gain back the same level of mobility they once had. These soldiers have exhibited a better healing rate compared to those that stayed inside the confines of the wards post-op.

The method is so effective that an organization has been founded in its honor; the American Horticulture Therapy Association (AHTA). This association offers professionals an opportunity to practice plant therapy and be a registered Horticultural Therapist.

What Are the Health Benefits of Having Plants Around You?
Aside from improving our mood and making us happy, having plants in our homes can also improve our physical health. If you need more convincing on why plants should be part of your interior decor, look no further, here are some health benefits plants can provide:

Plants Help You Breathe Better

Oxygen is essential to the human body, in the process of respiration, we exhale carbon dioxide. During a plant’s active phase, it goes through photosynthesis. This is when the plant absorbs the carbon dioxide in the air, along with water, light, and soil nutrients. The waste product of plants during photosynthesis would be oxygen. Essentially, plants help increase the oxygen levels in a given space.  Therefore when there is an abundance of oxygen in the air, the easier it is for us to breath.

Ideally, photosynthesis only happens during the day. At night, the plants would be releasing carbon dioxide, which is why it is advisable to choose a plant that continuously produce oxygen throughout the day. These plants would be ideal for you bedroom.

They Keep You Away From Illnesses

In nature, plant roots access groundwater and allows it to evaporate through its leaves. This process is also know as transpiration. The moisture in the atmosphere actually come from this, which makes the surrounding environment relatively cooler. At home, most indoor plants do the same thing. They are able to stabilize the humidity. In a study conducted at the Agricultural University of Norway, it is said that plants within living spaces are able to reduce the incidence of dry skin, sore throats, dry coughs, and even colds. With higher absolute humidity, thanks to indoor plants, the survival of the flu virus is also affected.

They Absorb the Toxins in the Air

The National Aeronautics and Space Administration (NASA) conducted a study on plants and air quality back in 1989. The extensive research was able to prove that a number of houseplants are able to improve the overall air quality. It is said, that both leaves and roots are able to remove toxins from the air within sealed spaces. Toxins that are harmful to humans like Carbon Monoxide, Benzene, and Formaldehyde can easily be absorbed by certain plants. In addition to this, we know that plants give out oxygen and it is because of this, we are able to breathe better, and cleaner air that is not riddled with toxins.

According to this same researcher, NASA experts recommend that one potted plant must be placed within a hundred square fee of indoor space for optimum results.

It actually helps the patients feel better. It is said to be a completely inexpensive, non-invasive and effective form of complimentary treatment for post-operative patients. A study done in Kansas State University was able to prove this claim when patients that were able to view plants post-op had a significant improvement with their physiologic responses. Their blood pressures were regulated, the pain was more tolerable, there is less anxiety, and less fatigue. This is as opposed to patients that did not have plants in their rooms.
