Your heart rate synchronizes with theirs.
Your heart may skip a beat when you think about the one you love, but a study showed that you may also be beating in time with each other. A study conducted by the University of California, Davis, suggests that couples’ hearts begin to beat at the same rate when they fall in love.
Although you may not be able to tell if this has happened without a few stethoscopes, feeling a deep connection to your partner is a good a sign as any that you’re in love.
You’re OK with the gross stuff.
If you’re a notorious germaphobe and totally cool kissing your partner after just watching them pick their nose, you might just be in love. In fact, a study by the University of Groningen in the Netherlands found that feelings of sexual arousal can override feelings of being grossed out.
So that means if you’re super attracted to your partner, you may just let them double dip. That’s love, baby.
