A “Digital Detox” during your sabbatical is perfect since you don’t need to be constantly available anyway, and you won’t have many obligations in your work and private life. No matter how you organize your sabbatical – whether you spend time with your family, take up a hobby, do voluntary work, travel etc. – you will definitely experience a lot of exciting things that distract you from your abstinence.
Of course, it’s up to you how long you would like to do a “Digital Detox”. Whether it is just at the weekend, during the week, for several weeks, or even during your whole sabbatical is only your decision. What can be said for sure is that it won’t do any harm to put your smartphone aside for a while to experience and enjoy your sabbatical even more intensely.
