Sensationalized news reports about theoretical radiation health hazards posed by electronic devices like cell phones, computer monitors and electric power lines often alarm the public for no reason other than attracting readers or viewers. The reported experiments involve doses of radiation far beyond what users of electronic devices are exposed to. Or the experiments are performed with lab animals or cells in a lab dish, hardly real world environments.
However, a recently published study sets off real alarm bells. Researchers report that low-dose EMF (electromagnetic field) radiation emitted from computer monitors adversely affects thyroid hormone levels in females, a problem that was surprisingly reversed by zinc supplementation.

Sleep: Trying to get 8 hours of uninterrupted sleep may be frustrating. Modern humans are going to sleep two hours later than the daylight-darkness cycle. Prior to electric lighting, people slept for about 6 hours, awoke for about two hours, and then went back for a second sleep. Blue light emitted from electronic devices, even smart phones, or computer monitors fouls up melatonin secretion, the sleep hormone. Be aware. Blue light filters are available for computer monitors and eyeglass lenses. However, no one is mentioning that blue light filtering in the AM is counter-productive and impairs the dissipation of melatonin and could theoretically induce daytime sleepiness. Best to get some direct sunlight early in the AM to awaken fully refreshed and alert.

Low thyroid hormone levels can result in mental confusion. Which only adds to the bewildering state of affairs when it comes to recognizing and rectifying low or high thyroid hormone levels.
While thyroid hormone dysfunction affects 1% of the general population it affects 10% of senior adults (10% females; 6% males).
Many millions of Americans rely on thyroid hormone replacement. But about as many (13 million estimated) may have low thyroid levels and don’t know it.
