63 / 100
Mostly True

Loneliness weakens the immune system, while friends and loved ones can increase immunity by 60 percent.

Infact verdict: Mostly True (63/100).

The claim that loneliness weakens the immune system is supported by multiple sources indicating that loneliness can increase inflammation and reduce immune response efficiency. However, the claim that friends and loved ones can increase immunity by 60 percent lacks specific evidence to support the exact percentage, though social connections are generally shown to improve immune function.
