There are some people whom you can’t unfriend or block for some unavoidable reason but you can surely unfollow them so that their posts don't show on your news feed.
And now just like the feature of WhatsApp, Facebook is working on a “Snooze” feature. With the help of this feature, you will be able to mute a person temporarily in your friend list or from any page or group.
When you are about to mute someone you will see at the top right of the publication, the ‘unfollow’ option, which will ask you to select the time period of 24 hours, 7 days or 30 days. After you have set the date range, your news feed will come back to usual, based on the news feed algorithm.
This is a very useful feature because sometimes we do get annoyed by some people who keep on post pictures and status of their each and every activity or some group is overly excited for some of the other reason.
However, this useful feature has not been released for the users, the company is still testing it. Once finalized it will be released globally.
