2. Gardening is good for your cardiovascular health

  1. The Sweedish study mentioned above came to the conclusion that gardening and housework reduced the risk of a heart attack or stroke in seniors by 27 percent by providing people with physical exercise.
  2.  A study of adults in Perth, Australia demonstrated  that “the odds of hospitalization for heart disease or stroke was 37% lower among adults in neighborhoods with lots of greenery”.
  3.  A study conducted on nearly half a million individuals  in Taiwan showed that 15 minutes of moderate exercise (which gardening can provide)  reduced the risk of cardiovascular mortality by 19%.

3. Gardening wards off dementia

According to an Australian study, daily gardening reduces risk of dementia by 36%.

4. Gardening is good for your respiratory system


The above mentioned The Nurses’ Health Study (2016 Harvard study) discovered that being exposed to a green natural environment lowers risk of death from respiratory illnesses by 34%. This most likely happens because greenery and trees improve air quality by reducing air pollutants.

5. Gardening supplies you with vitamin D

Do you know that almost 50% of the world population are affected by vitamin D insufficiency mainly because of reduced outdoor activities? 

The major source of vitamin D is exposure to natural sunlight and when you garden you naturally will be getting vitamin D. 

Vitamin D deficiency results in poor calcium and phosphorus absorption by the body and can lead to osteoporosis. Also, lack of vitamin D can contribute to autoimmune diseases: multiple sclerosis, type 1 diabetes, rheumatoid arthritis, and autoimmune thyroid disease.

6. Gardening may reduce obesity

Gardening makes you physically active, thus can reduce obesity. 

There were 60 studies about association of living in green spaces and obesity related health indicators and two thirds of them found positive to mild correlation to living in green space and lower obesity levels. 

7. Gardening boosts your immune system

Not only does eating fresh from the garden fruits and vegetables (which are full of antioxidants and vitamins) boost your immune system, but playing in the dirt 🙂 does it too. 

This happens because working with the soil exposes people to Mycobacterium vaccae  bacteria which according to 2019 study has anti-inflammatory, immunoregulatory, and stress resilience properties.

8. Gardening improves your mental health and fosters a feeling of happiness

  1. One of the reasons why gardening makes you feel happy can be  explained again by Mycobacterium vaccae bacterium that people inhale while gardening. Research by scientists in England showed the potential role of this bacterium  in regulation of emotional behavior by increasing levels of serotonin and decreasing levels of anxiety.  
  2. Research papers by multiple scientists (for example,  Hartig et al. 2014; Taylor et al. Gascon et al. 2015), state that direct contact with nature decreases physiological stress and depression. 

9. Gardening provides relief from stress

Dutch scientists conducted a study where 30 people were divided into 2 groups. All participants were exposed to the same stressful task after which one group was gardening outdoors for 30 minutes, and the other group was reading a book for 30 minutes. 

After that the cortisol level in saliva was measured. The cortisol level of gardening group participants dropped significantly in comparison with the reading group. Also, the group that gardened reported that their positive mood was restored after gardening. The group members that were reading reported that their mood actually further deteriorated during reading.

10. Flowers impact your emotions positively

Do you know that flowers impact your emotions positively and a woman that has been gifted flowers feels uplifted 3 days afterwards?

3 different studies found that “Flowers have immediate and long-term effects on emotional reactions, mood, social behaviors and even memory for both males and females.”
