Smoking can have a huge impact on a man’s erections. In fact, in 2014 the acting U.S. Surgeon General added erectile dysfunction (ED) to the list of conditions that can be caused by smoking.
Research has shown that men who smoke are at higher risk for ED. Often, erection problems are worse for men who smoke heavily and those who have smoked for a long time. Secondhand smoke may also interfere with erections.
It’s possible that caffeine could help a man’s erections, but more research is needed.
Caffeine is a stimulant found in foods and beverages. Coffee, tea, soda, and energy drinks are common sources.
Past research has found that caffeine may have some health benefits, but its role in erections has been unclear.
