WiFi does not cook food despite sharing frequencies with microwave ovens due to low power
Although Wi-Fi operates on frequencies similar to microwave ovens, its output power is orders of magnitude too low to heat or cook food.
The provided literature consistently indicates that Wi-Fi devices emit nonionizing electromagnetic radiation at extremely low power densities that rapidly decay over distance and remain well below safety thresholds, confirming that they do not possess the high energy or heating capacity of microwave ovens.

Paper 0 notes that Wi-Fi devices have a much lower output power compared to other sources while using similar nonionizing frequencies.

Paper 1 demonstrates that Wi-Fi electromagnetic fields exhibit aggressive spatial decay and remain strictly localized at very low levels.

Paper 5 measures ambient Wi-Fi exposure levels as a tiny fraction of international safety reference levels in real-world settings.

Paper 9 confirms that Wi-Fi power densities from laptops fall vastly below regulated safety limits for human exposure.
