Kissing, a common display of affection seen everywhere from movies to real-life couples, isn't just about romance. Health experts point out that there are potential side effects to this intimate act, especially when it comes to spreading infections. The transfer of saliva can lead to the quick spread of contagious diseases like colds and the flu.
Those with allergies may also spread or exacerbate issues like rashes and swelling through a simple lip-to-lip kiss. Dental problems, including gum diseases, can worsen or be initiated due to the bacteria exchanged during a kiss. Moreover, sexually transmitted infections such as chlamydia and gonorrhea can also be transmitted through intense kissing.
Long-term illnesses from one person can potentially transfer to another, increasing the risk of more severe bacterial infections like pneumonia. Kissing might seem like a harmless token of affection, but it's essential to be aware of these health risks, particularly with new or multiple partners.
