There has been much recent research suggesting that people who are married seem to have better health than people who live alone. However, the key factor is whether or not a person is lonely.
Research shows that chronically lonely people may be at higher risk for coronary disease, certain cancers and other types of inflammatory diseases because their feelings of social isolation trigger the activity of pro-inflammatory cells.
The inflammation that results can help to rupture coronary artery blockages. Then cholesterol can be released into the blood stream, mix with the blood, and produce a large blood clot. This in turn can seal off blood to the heart and trigger a heart attack. Other things that increase inflammation are smoking, gum disease and chronic stress.
Humans are social creatures. Loneliness is living without the encouraging emotional support of friends or family. I believe this can negatively impact a person's well being, causing unfavorable physiological changes.
The happiness we derive from interacting with close friends who are supportive, and share a laugh or two, would have a positive impact on our health.
