6. Touch and Smell
Now that you have plants in your home, interact with them. Touch and smell them everyday. By touching and smelling, you are waking up two senses that are very deprived from nature in the city.
Recent research has shown that the smell of humus (organic component of soil from degraded leaves) brings a physiological effect on humans. This scent stimulates the release of the hormone oxytocin, the same chemical that promotes bonding between mother and child, and between lovers. Through touching your plant’s soil, you are becoming familiar with how often each plant absorbs water. By gently touching your plant’s leaves and stems, you are activating their immune system and helping them to fight off bacteria and fungus. If you live alone, this is a great way to keep your touch sensory system strong and satisfied.
