We all know that the holidays can bring loneliness, tension and overindulgence. Why not give your body a gift and celebrate with a little solo sex. It’s good for your health, according to researchers Spring Chenoa Cooper and Anthony J. Santella from the University of Sydney.

They write, “For men, masturbation helps reduce risk of prostate cancer, probably by giving the prostate a chance to flush out potential cancer-causing agents.”

Women benefit from the increased fluid circulation that masturbation provides. “For women, masturbation can help prevent cervical infections and urinary tract infections through the process of ‘tenting,’ or the opening of the cervix that occurs as part of the arousal process.”

For both sexes, masturbation may help lower the risk of type-2 diabetes, improve sleep quality and boost immune functioning. It also gets your endorphins pumping, which reduces depression—something many of us face during the holidays.

Just one question that remains: If you spend a lot of the holiday season pleasuring yourself, and it’s good for you, does that count as “naughty” or “nice”?
