But notifications and vibrations can also wake you up just as you&#x27;re nodding off — so best to put your phone on ‘do not disturb.&#x27;</p><p>But the common belief that blue light emitted from your phone tricks the body into thinking it&#x27;s time to wake up isn&#x27;t quite right.</p><p>Blue light emitted from phones does not? affect circadian rhythms any more than other light wavelengths. What&#x27;s more impactful is the brightness of the light and duration of exposure.</p><p>Glasses or apps that block blue light on your phone or laptop don&#x27;t necessarily improve sleep — what&#x27;s more effective is turning down the brightness or reducing screen time.</p><p>And the type of internet content you view before sleep is also important. Studies show that watching scary movies or viewing disturbing social media content triggers the release of stress hormones, which interferes with restful sleep, reducing deep and REM sleep.</p><p>If you want to relax your mind and body before sleeping, it&#x27;s best to nod off with a book or an e-reader without a screen light. Some studies show reading before going to sleep improves sleep quality.</p><div><a href="https://www.abs-cbn.com/video/life/06/24/23/alamin-mga-tips-para-magkaroon-ng-sapat-na-tulog">ALAMIN: Mga tips para magkaroon ng sapat na tulog</a></div><div><br/></div><div><em>Edited by: Matthew Ward Agius<br/></em></div><div><em>Source: <br/></em></div><div><em>How and when screens are used: comparing different screen activities and sleep in Norwegian university students</em></div><div><em> </em></div><div><br style="caret-color:rgb(0, 0, 0);color:rgb(0, 0, 0)"/></div><div><iframe width="853" height="480" src="https://www.youtube.com/embed/nw-DUuRXqdM" title="Study: PH most sleep-deprived country in Southeast Asia, fourth in the world | ANC" frameBorder="0" allowfullscreen=""></iframe></div>
