Issues concerning the 2.4 GHz band

[neenerx2]

I am considering making a yagi antenna for a wifi adapter and I have been warned about some possible side effects that I wanted confirmed or disproved..

I read somewhere that the 2.4GHz band also is the resonant frequency of water and is used by microwave ovens, but at a more powerful rate than wifi of course.

But considering the adapter I'm using is a 2W long range device and the antenna theoretically would boost the signal by 12-14 dB, I wanted to know if that would be able to cause headaches, vision problems and such?

Also, since it's a directional antenna, if it could cause any side effects would it only be limited to the direction of the antenna or would it also affect it's immediate surroundings?

I am no expert in this and I hope you can help me here, I will have to reconsider making it if it cooks my brain by using it...

The 2.4 GHz band is a portion of the radio spectrum internationally allocated to the use of microwave radio relay for terrestrial communication. The band is used for many applications, including point-to-point radio links, telecom backhaul, wireless networking, and microwave radio relay.
