You may wonder why the Octopus Watch is synchronizing only when you hold the button for three seconds or when you plug the watch into a power source.

The Octopus Team, with feedback from parents, prioritize being careful about kids’ health. We want to expose kids to as few radio frequencies or waves as possible. When a kid is wearing his watch, there are no frequencies is his Octopus Watch unless you activate the Bluetooth.

Based on what scientific knowledge have we made this decision?

We are not in a position to know if exposure to electromagnetic radiation poses health risks to children's developing bodies.

However, in May 2011, the World Health Organisation's International Agency for Research on Cancer announced it was classifying electromagnetic fields from mobile phones and other sources as "possibly carcinogenic to humans" and advised the public to adopt safety measures to reduce exposure, like the use of hands-free devices or texting.

Plus, several nations have advised a moderate use of mobile phones for children.

 A journal by Gandhi et al. in 2006 states that children receive higher levels of SAR. When 5- and 10- year-olds are compared to adults, they receive about 153% higher SAR levels. Also, with the permittivity of the brain decreasing as one gets older and the higher relative volume of the exposed growing brain in children, radiation penetrates far beyond the mid-brain.

SAR is a measure of the rate of RF (radiofrequency) energy absorption by the body from the source being measured – in this case, a cell phone.
