Can you relate? Do you notice a difference in falling asleep if you were to use your cell phone before going to bed? While it is not as obvious as a skin rash, the results of the study run by universities in Sweden and the US show that there is a relationship.
This study and other related studies conducted previously show that exposure to 884 MHz wireless band delays and reduces sleep, but more specifically activates the brain to be more alert and focused making it difficult to unwind and fall asleep.
