If you’ve ever felt guilty about the amount of time you spend primping and preening yourself then it’s time to stop worrying. A new study released by US drug store CVS has found that devoting time to personal care has significant short and long-term health benefits. Yay!

Study findings by Dr. Vivian Diller, a practicing psychologist based in New York City, who compiled evidence over 20 years, proves that all that time in front of the mirror isn’t wasted.

“Activities that allow us to take care of our personal beauty needs should not be viewed as ‘guilty pleasures,’”  Dr. Vivian Diller told Yahoo Beauty. “These acts may help us live a long and vital life well into our 80s and 90s.” The study focused on the concept of “subjective well-being,” something that psychologists have been studying for years and are just now connecting to beauty.

Dr. Diller gives an example of putting on a lipstick before a date. As soon as you apply it and look in the mirror, you start to feel differently, think differently, and your behavior and interactions change. This confidence and positivity leads to subjective well-being, which has been linked to better eating, sleeping, self-care, and boosted immunity. “The experience of subject well-being actually improves your health,” she says.

“You should allow yourself to see beauty as staying healthy for the rest of your life,” says Dr Diller, who also stressed the importance of relaxation as part of a daily routine in the study. “We know that on multiple biological levels, from the cardiovascular system to cellular growth, if we include relaxation we are very likely to slow down the natural deterioration of our bodies that come with age,” she says. Perhaps the biggest benefit to routine relaxation is the reduction of cortisol, a stress hormone that impacts our cardiovascular system.

So next time your partner complains that you’re taking too long getting ready just say you’re working on your long-term health and wellbeing.
