How many hours per week do you spend on social media sites? Used in moderation, these sites may help you foster social ties. They may also give you a platform to express your thoughts, feelings, and values. But, studies show that constant use of these sites may be linked to feelings of stress and anxiety. Overuse may also lead to sleep loss, depression, and loneliness. If you can, try chatting on the phone or in-person more often. Think about your social media habits. Are they doing more harm than good? Be sure to talk to your doctor if you’re not sure.
