Effects of 2.45 GHz Wi‐Fi exposure on sleep‐dependent memory consolidation

Effects of 2.45 GHz Wi‐Fi exposure on sleep‐dependent memory consolidation

Studies have reported that exposure to radiofrequency electromagnetic fields (RF‐EMF) emitted by mobile telephony might affect specific sleep features. Possible effects of RF‐EMF emitted by Wi‐Fi networks on sleep‐dependent memory consolidation processes have not been investigated so far. The presen...

description Studies have reported that exposure to radiofrequency electromagnetic fields (RF‐EMF) emitted by mobile telephony might affect specific sleep features. Possible effects of RF‐EMF emitted by Wi‐Fi networks on sleep‐dependent memory consolidation processes have not been investigated so far. The present study explored the impact of an all‐night Wi‐Fi (2.45 GHz) exposure on sleep‐dependent memory consolidation and its associated physiological correlates. Thirty young males (mean ± standard deviation [SD]: 24.1 ± 2.9 years) participated in this double‐blind, randomized, sham‐controlled crossover study. Participants spent five nights in the laboratory. The first night was an adaptation/screening night. The second and fourth nights were baseline nights, each followed consecutively by an experimental night with either Wi‐Fi (maximum: psSAR10g =

Declarative, emotional and procedural memory performances were measured using a word pair, a sequential finger tapping and a face recognition task, respectively. Furthermore, learning‐associated brain activity parameters (power spectra for slow oscillations and in the spindle frequency range) were analysed. Although emotional and procedural memory were not affected by RF‐EMF exposure, overnight improvement in the declarative task was significantly better in the Wi‐Fi condition. However, none of the post‐learning sleep‐specific parameters was affected by exposure. Thus, the significant effect of Wi‐Fi exposure on declarative memory observed at the behavioural level was not supported by results at the physiological level. Due to these inconsistencies, this result could also be a random finding.</description><identifier>ISSN: 0962-1105</identifier><identifier>EISSN: 1365-2869</identifier><identifier>DOI: 10.1111/jsr.13224</identifier><language>eng</language><subject>declarative memory ; EEG power ; emotional memory ; procedural memory ; sleep spindles ; slow oscillations</subject><ispartof>Journal of sleep research, 2021-08, Vol.30 (4), p.e13224-n/a</ispartof><rights>2020 The Authors. published by John Wiley &amp; Sons Ltd on behalf of European Sleep Research Society</rights><lds50>peer_reviewed</lds50><oa>free_for_read</oa><woscitedreferencessubscribed>false</woscitedreferencessubscribed><citedby>FETCH-LOGICAL-c3374-4a6ab4f083fd75426fbaaddba5bb4c68fb764095c07481793999753cd28d598a3</citedby><cites>FETCH-LOGICAL-c3374-4a6ab4f083fd75426fbaaddba5bb4c68fb764095c07481793999753cd28d598a3</cites><orcidid>0000-0003-2390-219X ; 0000-0001-7001-1715</orcidid></display><links><openurl>$$Topenurl_article</openurl><openurlfulltext>$$Topenurlfull_article</openurlfulltext><thumbnail>$$Tsyndetics_thumb_exl</thumbnail><linktopdf>$$Uhttps://onlinelibrary.wiley.com/doi/pdf/10.1111%2Fjsr.13224$$EPDF$$P50$$Gwiley$$Hfree_for_read</linktopdf><linktohtml>$$Uhttps://onlinelibrary.wiley.com/doi/full/10.1111%2Fjsr.13224$$EHTML$$P50$$Gwiley$$Hfree_for_read</linktohtml><link.rule.ids>314,778,782,1414,1430,27911,27912,45561,45562,46396,46820</link.rule.ids></links><search><creatorcontrib>Bueno‐Lopez, Ana</creatorcontrib><creatorcontrib>Eggert, Torsten</creatorcontrib><creatorcontrib>Dorn, Hans</creatorcontrib><creatorcontrib>Schmid, Gernot</creatorcontrib><creatorcontrib>Hirtl, Rene</creatorcontrib><creatorcontrib>Danker‐Hopfe, Heidi</creatorcontrib><title>Effects of 2.45 GHz Wi‐Fi exposure on sleep‐dependent memory consolidation</title><title>Journal of sleep research</title><description>Studies have reported that exposure to radiofrequency electromagnetic fields (RF‐EMF) emitted by mobile telephony might affect specific sleep features.
