Mental and emotional health is just as important as one's physical health. There are numerous ways to care for one's mental health, such as meditating, and we think the Muse 2: The Brain Sensing Headband ($250) is a great tool for those just getting started with meditation.
This headband is essentially a personal meditation assistant, providing you with real-time feedback as you meditate. It will let you know when you're calm and focussed, and it will provide gentle signals letting you know when it senses your mind beginning to wander.
