Dark mode is becoming more common on social media.

Dark modes have been rolling out across various social media platforms over the past 18 months or so. Dark mode is popular as it can be a lot easier on your eyes, especially if you need to look at a screen for a number of hours at a time and if using a smartphone or desktop at night. Artificial light has been shown to suppress the sleep-inducing hormone, melatonin, which could disrupt your sleep patterns, so if you must use a smartphone before bedtime, dark mode is a good idea.

Rather than leave you in the dark, we thought we would collate the instructions of how to activate dark mode on the popular social platforms. 

Twitter – Desktop

You can toggle dark mode on and off by clicking on your profile icon in the top right-hand corner and scrolling down and clicking ‘Dark Mode’.
