How To Use And Applicable Scenarios For Handheld Sleep Aids

Before use, ensure the device is fully charged (usually via USB-C). Press and hold the top power button for 2 seconds to start, and press briefly to switch between power levels.

 

It is recommended to use the device 15-30 minutes before bedtime. Hold the device in your palm, adjust to a comfortable power level, and keep it still to avoid frequent movement that may affect the effect.

 

The device is suitable for various scenarios: dealing with jet lag during business trips, quickly relaxing during office lunch breaks, and relieving eye strain while reading at home. Note that pregnant women, pacemakers, or people with sensitive skin should consult a doctor before use to avoid discomfort due to individual differences.
