Get a fish tank
Watching live fish has been found to boost mood and even lower blood pressure (yes, really!). The gentle sound of a bubbling filtration system can contribute to a feeling of calm relaxation, like a massage for your brain. Close observation of fish grounds you in the present moment, so it could even serve as an effective meditative technique. Don’t own a fish tank? Visit your local aquarium or a neighborhood pond to connect with nature—and tune into tranquility.
