The concept that your state of mind affects your physical health is hardly a new one – after all, who hasn't heard such as adages as "turn that frown upside down" or "laughter is the best medicine." But, as heartwarming as this idea may be on its own, it's comforting to know there is actually some medical research behind it.

A new study has shown that abandoning negative self-talk in favor of a more positive outlook has shown significant anti-aging effects for older individuals who spend a lot of time alone. According to researchers from Concordia University in Quebec, self-protective strategies such as speaking kindly to yourself and looking for the good in any situation may actually protect people from age-related illnesses. How? By preventing the body from producing too much cortisol and C-reactive protein – two compounds associated with extreme stress.

"The long-term activation of the stress-response system – and the subsequent overexposure to cortisol and other stress hormones – can disrupt almost all your body's processes," the Mayo Clinic explains.

That disruption can lead to the development of heart disease, obesity and depression, along with other issues that can significantly impair your quality of life.

But, as ScienceDaily reports, the Canadian researchers discovered that, among 122 senior citizens already coping with significant health issues, simply thinking positively and ceasing to accost themselves for their limitations was enough to lower their everyday stress levels, stemming their production of anxiety-based hormones and ultimately staving off other health risks.

Of course, staying positive is sometimes easier said than done, particularly if you're struggling with hormonal changes that leave you feeling depleted. Longevity Centres of America is dedicated to helping clients live well, and provides anti-aging treatments such as hormone pellet therapy for those who need an invigorating boost to lift their spirits.
