Er wordt onder andere bepaald welke informatie moet blijven en wat eventueel weg mag. Je slaapt vaak in verschillende fases, waaronder je inslaapfase, lichte slaap, diepe slaap en je REM-slaap. Vooral je diepe slaap is belangrijk want dan maakt je lichaam belangrijke groeihormonen aan. En daarnaast worden afvalstoffen van je hersenen afgevoerd om ze vervolgens uit te kunnen plassen.</p> <p>Slaap je te weinig, dan ga je vaak slechter presteren. Zo staan studenten die slecht slapen gemiddeld zo'n 0,5 punt lager dan hun medestudenten. Op de lange termijn is slaaptekort zelfs gelinkt aan dementie, hartfalen, verminderde vruchtbaarheid bij mannen, overgewicht, kanker, depressie en diabetes type 2.</p></span></div></section><div><div id="id-1"><section class=""><div class="Container_container__OqKJF Container_isSmall__t2Nh4"><div class="u-margin-top-lg"></div><div class="u-margin-top-sm"><div class="BalloonShapeRelative_shape__SzreA BalloonShapeRelative_colorYellow__Kg2Jl"><div><span class="RichHtml_wrapper__KqHnh"><p>Meer weten over slapen?
