We like to wind down at night with the Therabody Smart Goggles, which feature SmartSense Technology to lower our heart rate and reduce stress and anxiety. It features three modes--Focus, SmartRelax, and Sleep--to soothe our headaches, relieve eye strain, ease facial tension, and help us rest. The Smart Goggles charge through the included USB charging cable for 150-minute battery life (depending on mode) and can connect to a Therabody app via Bluetooth for sound therapy that complements the vibration, massage, and heat modes for a restorative, multisensory experience.
