2. IT CAN SPREAD VIRUSES LIKE MONONUCLEOSIS AND MENINGITIS THAT CAN PUT YOU OUT FOR WEEKS, IF NOT MONTHS.
They’re two of the most commonly transmitted pathogens via kissing, according to Reynolds. Since the mono virus can persist and cause symptoms like extreme fatigue for upward of six months in some people, and meningitis, the inflammation of the membranes surrounding your brain and spinal cord, can last up to 10 days, sometimes causing permanent and even life-threatening damage, neither conditions are remotely desirable.
3. IT CAN LEAD TO A SEXUALLY TRANSMITTED INFECTION.
As you (hopefully) learned in sex ed, microbes that cause gonorrhea, syphilis, herpes, and HPV can be transmitted through saliva. Often asymptomatic, these can easily be passed between partners in acts as innocent as kissing.
