5 FURTHER WORK
A repeat study is now underway in which 20 of the
original cohort of 50 have repeated their
participation. The aim is to discover if those who
showed strong Alpha power changes in the first
study show similar changes in the second. There has
been some speculation that sensitivity to EMF may
vary with the individual.
6 CONCLUSIONS
Alpha power findings are inconsistent across studies,
but sleep studies may show slightly more
consistency. The actual frequency range for
significant increases varies between studies and even
between studies from the same laboratory.
Nevertheless, the preponderance is of reported
increases in alpha power: this may relate to
increased blood flow in superficial regions of the
face or ear or increased tympanic membrane
temperature. It is difficult however to envisage how
these effects could persist several hours after
exposure. Overall, the evidence is insufficiently
strong to conclude that mobile phone emissions
affect sleep.
