Women connect with each other differently and provide support systems that help each other to deal with stress and difficult life experiences. Physically, this quality “girlfriend time" help to create more serotonin - a neurotransmitter that helps combat depression and can create a general feeling of well-being. Women share feelings whereas men often form relationships around activities. We share from our souls with our sisters/mothers, and evidently that is very GOOD for our health. The lecturer stated that spending time with a friend is just as important to our general health as jogging or working out at a gym.
There's a tendency to think that when we are "exercising" we are doing something good for our bodies, but when we are hanging out with friends, we are wasting our time and should be more productively engaged—not true. In fact, it is the failure to create and maintain quality personal relationships with other humans that is as dangerous to our physical health as smoking!
So every time you hang out to schmooze with a gal pal, just pat yourself on the back and congratulate yourself for doing something good for your health, well, I suppose as long as you aren’t overdoing the drinking and smoking at the same time!
