Happy people seem to enjoy better health and longevity, but more research is needed to understand why. Research indicates that happiness could increase lifespan by years—suggesting maintaining a happy, positive mood may be an important part of a healthy lifestyle. Believe it or not, smiling can reduce stress even if you don’t feel like smiling or even if you fake it with a smile that isn’t genuine. When you are stressed, try intentionally putting a smile on your face. It may help improve your mood and ability to manage the stress you are experiencing. The physical act of smiling activates pathways in your brain that influence your emotional state—meaning that by adopting a happy facial expression, you can “trick” your mind into entering a state of happiness. This affect works whether or not your smile is genuine. A simple smile can trigger the release of neuropeptides that improve your neural communication. It also causes the release of neurotransmitters such as dopamine and serotonin, which can boost your mood. Think of smiling as a natural antidepressant. Research suggests that smiles are actually contagious. Your brain automatically notices and interprets other people’s facial expressions—and sometimes, you may even mimic them. That means you might spot someone else’s smile and unconsciously smile yourself. Whether you’re trying to maintain your overall health or strengthen your immune system ahead of cold and flu season, smiling may help. Warding off illness and staying healthier can also play a role in helping you feel less stressed. If you have a blood pressure monitor at home, you can try testing this idea for yourself. Sit for a few minutes and take a reading. Then smile for a minute and take another reading while still smiling. Do you notice a difference? Not only can smiling make you more attractive, but it can also make you look more youthful. The muscles we use to smile also lift the face, making a person appear younger. So instead of opting for a facelift, just try smiling your way through the day—you’ll look younger and feel better. Smiling can influence your feelings of positivity, even if it feels unnatural or forced. Regardless of whether or not your smile is genuine, it still sends the message that “Life is good!” to your brain and, ultimately, the rest of your body.
