From a basic science perspective, there is little plausibility to the notion that Wi-Fi radiation would have any health effects. The amount of energy that is absorbed by a person living in a Wi-Fi field is negligible - less than 1% of exposure from a typical cell phone and well below current safety levels.But he advances a different explanation for children getting ill during school hours:
Stress alone is a sufficient explanation, but there may be others. For example, many students go to school sleep-deprived because they are staying up too late. This is not an issue on weekends and over the summer. Sleep deprivation is a good explanation for most of the symptoms being reported.He concludes this is another example of lack of critical thinking skills being at the basis of a "controversy." While Orac notes:
Did it ever occur to them that complaining of feeling sick is a good way to get out of school for the day?Also, he stresses the always ignored maxim "correlation is not causation." Something invariably absent from the anti-science movement.
Update: Dutch trees appear unaware of the above:
A study by some Dutch scientists claims to have shown that WiFi kills trees [Study Says Wi-Fi Makes Trees Sick].Note the important advise on how to protect against this evil.
