Final answer:
Increased closeness can lead to overdependence and dissatisfaction in relationships due to constant connectivity. The stress from negative aspects of close relationships can adversely affect physical health, such as causing heart problems. Additionally, closeness may result in narcotizing dysfunction where people are less actively involved due to being overwhelmed by constant media exposure.
Step-by-step explanation:
One problem that may arise from increased closeness is the potential for overdependence and differing expectations within relationships, particularly as facilitated by the use of mobile devices. Constant connectivity can lead to feelings of entrapment and the pressure to respond immediately, which research has suggested can cause dissatisfaction (Hall 2012).
In addition, the negative aspects of close relationships, such as conflict, lack of emotional support, and lack of reciprocity, could become overwhelming and result in considerable stress. This stress can have severe repercussions on physical health, as evidenced by a longitudinal study indicating that individuals experiencing high levels of negative interactions are more likely to suffer serious heart problems (De Vogli, Chandola, & Marmot, 2007). Moreover, there's a concept known as narcotizing dysfunction, where the relentless influx of media and technology leads to an overwhelmed state, diminishing actual engagement in relationships (Lazerfeld and Merton 1948).
Excessive closeness can also contribute to inbreeding depression in more scientific terms, where mating between closely related individuals leads to an increased risk for abnormalities and diseases.
