It can be easy to spend a lot of time online, but being aware of how often and why you go online can help you work out a healthier and happier balance with time offline. Being online should enhance our lives, not dominate them. If you feel the need to constantly refresh your apps or check your notifications, or if you find you're defining yourself by your 'extremely online' humour, it's probably time to take a break. Why? Because too much time online can make study, work and relationships more difficult and even drag down your physical and mental health.
