The human mind is wired to connect to other people and if it fails it responds by being lonely.
Loneliness might result from a divorce or separation, failing to get married due to personal reasons, work demands, inadequate sleep, not spending enough time with friends and loved ones or even death.
The advancement of technology has made family bonding to be replaced by phone bonding which increases cases of boredom and loneliness compared to the past when people would hang out around each other more often.
People who spent most of their time alone feel lonely and are prone to increased health issues due to isolation and boredom. They are likely to have heart diseases, immune-related disorders or even stoke.
Loneliness and isolation increase the risks of high blood pressure and makes them become more violent. This is because of increased thoughts that in turn lead to depression as well as stress.
Uncontrolled stress elevates the amounts of cortisol hormone which decreases the immune system's response to infections hence leading to cell invasion by disease-causing microorganisms that result in cell death.
Loneliness has been attributed to less active genes that play the role of inhibiting inflammation. This exposes lonely people to inflammatory infections such as asthma. Therefore, it is quite important to avoid loneliness at all costs.
