What are SAR Levels, and do SYB Products Help Lower Them?Updated 7 days ago
SAR (Specific Absorption Rate) measures how much radiofrequency (RF) radiation your body absorbs from a device like a cell phone. SYB products are designed to reduce your exposure to that radiation, and by doing so, they help lower the effective SAR your body receives.
What Is SAR?
SAR stands for Specific Absorption Rate and is expressed in watts per kilogram (W/kg). It represents the rate at which the body absorbs energy from RF-emitting devices, such as:
Cell phones
Tablets
Bluetooth headsets
Smartwatches
Every device has a tested SAR value, which is regulated by government safety limits (e.g., 1.6 W/kg in the U.S. per the FCC).
However, SAR only measures exposure under specific lab conditions, typically when the device is held a certain distance from the body. Real-world usage—like carrying a phone in your pocket—can result in significantly higher absorption.
How SYB Products Help Lower Effective SAR
SYB’s shielding products are not built into the device, so they don’t change the tested SAR value. But they reduce the radiation that reaches your body, which effectively lowers the amount of energy your tissues absorb.
For example:
The SYB Phone Pouch shields the side of your phone that faces your body, redirecting radiation away and reducing how much reaches your tissues.
The SYB Laptop Pad blocks radiation from the underside of your laptop, protecting your lap and reproductive organs.
Lab tests confirm that these products block up to 99% of RF radiation, reducing your real-world SAR exposure significantly.
Summary
SAR is a measure of how much RF energy your body absorbs from a device.
SYB products don’t alter device SAR ratings, but they do reduce the amount of radiation that reaches your body.
This effectively lowers your actual exposure, especially during close or prolonged contact with EMF-emitting devices.
