The 'Timeline Cleanse' is a popular social media practice used to break up a stream of stressful news, politics, or negative content with something purely wholesome and visually pleasing. Whether it’s a high-definition photo of a capybara, a video of a puppy sleeping, or a serene landscape, the meme serves as a 'palate cleanser' for the digital mind. It gained significant traction during the mid-2010s on platforms like Twitter and Tumblr as users began collectively recognizing the impact of 'doomscrolling.' Today, the Timeline Cleanse is a vital part of internet etiquette, providing a moment of peace and a reminder that there is still beauty and humor in the world amidst the chaotic daily news cycle.
