Numerous studies have shown that constant physical activity is directly related to longevity. An important factor is that it is better to play sports with family and friends, and not alone. Scientists link increased mortality to social isolation, so communication and sports can positively affect health.

Lisa Berkman, director of the Harvard Center for Population and Development Studies, and Thomas D. Cabot, professor of public policy and epidemiology at the Harvard T.H. Chan, analyzed many studies that showed that social isolation is associated with a mortality risk similar to other major risk factors such as smoking, drugs and alcohol.
The researchers tried to identify relationship between sports participation and life expectancy among middle-aged people.
The results showed that people who exercise, especially with family and friends, live longer. Loneliness has been found to increase cortisol levels, which affect a person's overall health.
Cortisol is a stress hormone produced in the adrenal glands. Elevated cortisol levels can lead to obesity, diabetes, and high blood pressure.
In another study published in Express, participants voluntarily contracted the flu virus and were then monitored by consultants .
Scientists found that those who were socially isolated were 45 percent more likely to get sick than other group members.
While stress and loneliness can cause negative changes in a person's biological systems, spending time with other people helps activate more beneficial processes, including the production of oxytocin.
Oxytocin is one of the four happiness hormones. Oxytocin has been found to lower cortisol levels, reduce pain, change the way our brains respond to potential stressful situations, and even promote new cell growth brain.
