Picture of YumaLiteThank you for allowing us to be a part of your wellness team.

The YumaLite is a consumer product designed to be used as part of a Wellness Lifestyle. A commitment to healthy lifestyle choices is an important factor in the journey to Wellness.

The SOTA YumaLite uses White and Red LED light to balance the effects of both decreased exposure to natural sunlight as well as the overexposure to blue light from modern technologies. The LED light gently recalibrates your body’s internal clock and helps to restore your natural rhythms.

The YumaLite is designed to be used independently, but can also be used together with any of the SOTA Products.

With proper care, your YumaLite should provide you many years of trouble–free use.

Please understand that results will vary.

Notes:
Color: Choosing to use White or Red light is a personal preference – both are just as effective at balancing the low energy and low spirits associated with decreased exposure to natural light.

When used to balance overexposure to blue light, Red light is used.

Arms: Do not bend the arms of your unit beyond reasonable extension.

Storage: Always store your unit in the carrying bag provided and box, if possible. Do not allow your unit to come in contact with water, extreme heat or moisture.

Cleaning: To clean your unit, use a slightly damp cotton cloth to wipe the unit and if necessary wipe with a diluted, water based cleaner. Do not use harsh solvents, cleaners or abrasive material of any kind. Do not submerge the unit in water.

How it Should Feel
Most individuals will not feel any sensation while using the YumaLite.

Typical Use
Length of Session: Build up time gradually. It is best to start slowly. Start with 10 minutes a day. Increase gradually to a minimum of 30 minutes each day.

Limit your use to a maximum of 90 minutes per day.

Length of Use: The unit should be used daily for a minimum of 7 days or longer. After the benefits have been achieved, simply use the unit as needed.

When to Use: When used to help balance limited exposure to natural sunlight, use in the morning to help the body wake up and function normally. If required, add a second session in the afternoon.

When used to balance exposure to blue light, use in the morning, afternoon or early evening. If the Red light is too stimulating, limit usage to morning and afternoon.
