Handheld Microcurrent sleep/anxiety device

Handheld Microcurrent devices deliver small rhythmic electric stimulation to the palm of the hand to help increase focus and reduce anxiety and sleeplessness.
 
These lightweight devices weigh just 38g, have an easy to read LED display and come with charging cable. Sleep mode emits a microcurrent at a lower frequency and is perfect for relaxation and aiding in the transition to sleep. The excitement mode operates at a higher frequency and is perfect for enhancing focus and executive cognitive functions. Each mode has 15 intensity levels for comfort.
 
These devices do not treat the root causes of these conditions but rather are a tool for the temporary reduction of symptoms.
 
The exact mechanism by which they work is still unclear but multiple studies suggest they work by modulation electrical impulses of the nervous system. This helps regulate the release of neurotransmitters and stimulates the parasympathetic nervous system which is responsible for our 'rest and digest' state.
Another plausible explanation is that the rythmic sensation created by the microcurrent simply diverts attention towards the self and away from distressing or distracting stimuli the same way we do with mindfulness grounding techniques.
