Is wifi radiation/remote control alarm radiation can cause disease?

No!
Although it uses microwave range 2.4 GHZ but it's intensity is 1lakhs time low compared to microwave present in oven.This is confirmed by WHO

Moreover Chips are fabricated looking at a standard of IEEE and others which do care about humanity and thus sets particular frequency range that can't harm human.

Also the wave from wifi are non ionizing unlike dangorous radiation as that of Nuclear reaction or microwave,X-ray.

For your additional Knowledge do tell you

our Mobile, remote control alarm/car work on radio waves which are having range in KHZ unlike microwave as that in oven having range in GHZ with high intensity.

Also if you want to take one step precaution you can increase distance from source/basestation/router as far as i researched they say 100 feet (1feet = 30cm = two normal size scale) as intensity of EMW  follow inverse square law with distance.

How to Cure Cough Cold etc

Best Medicine are as follow

1)Ceptin-I --To remove allergy --Rs 50/-  --Best  !! But you may feel sleep after sometime ! This medicine can substitute following medicine. In my eyes this is the best medicine  --One time a day preferaably at night. At night durring sleep many healing process take place.

2)Torex or Golden Packet( Written  Nemuslide/paracetmol...lab lab! on packet)      -- Rs 40/- --2 times a day

3)CIPMOX 250( it is yellow silver capsule don't know why he give me google it )  --2 times a day
---------------------------------------------------------
1)  2) should be taken only if your nose run like a tap


3) should be taken only if throat in pain 

4) Medicine can change from person to person.I have shared as far as my personal experience is concern


If you are sneezing there is only best option and that is cough syrup (2 spoons 2-3 times a day) .
as far as my experience is concern in worse case bitter syrup work

anyway avoid syrups use natural remedy which is take salt in hot water and do gargale

4) should be taken if you are having khasi (snezzing)

The above medication is based on my personal experience for better perception you can approach well qualified government doctor.
