Cell tower radiation and its impact on health

There is an article in Times of India in which it is stated that apart from the heat generated during the use of mobile causing ill health, the electro magnetic effect on the body cells is more harmful. The symptoms of cell radiation is in the form of burning and tingling sensation in the skin of the head, fatigue, sleep disturbances, dizziness, lack of concentration, ringing in the ears, reaction time, loss of memory, headache, disturbances in digestive system and heart palpitation, etc.The recommended SAR of 1.6 watt/kg will help in reducing these effects, the report says. 
Though many these symptoms are known to appear even because of pollution, lack of good diet, workload at office, stress due to boss/peers, etc, the disappearing of doves and even pigeons, as reported in a news paper recently, adds strength to these findings. But, the above report is based on one professor's research report. The report also says to use speakers, restrict cell phone use to 6 min/day. I am not sure whether the study includes observations and measurements are result of studies conducted in less polluted areas like villages where though roads and transport is not available but cell towers and use of mobiles exists. As I said above, due to overlapping nature of symptoms from different sources (pollution, stress, etc), to understand the real reason i.e impact of cell towers and mobile use, the study should be conducted in an environment where pollution, work stress, etc are not present.
The first news paper article states that Indian cell phone users are more at risk for adverse affect of radiation due to hot tropical climate, low BMI and low fat content. On lighter side, we may conclude that, obese people are less prone to cellphone radiation effects. So, if you can't avoid cell phone use, increase your BMI, but face all problems due to high BMI.
Another report says Wi-Fi radiation is killing trees based on a study by exposing the trees to this radiation.

One thought that is in my mind for last few years is, though we say EMF due to cell towers poses health hazards to persons in the vicinity, we are not bothered about the radio waves that our body is constantly exposed whether we use cell phone or not. I feel that like cosmic radiation, the waves in the air also pose health hazards to entire humankind. When someone makes a call from his phone, as I understand, the signal from the cell tower hunts the destination mobile number and in the process like sun light falling on every person on the earth, in a similar fashion, all of us are exposed to these signals (or waves?).
