You get sweatier.
If you’re nauseous and sweaty, you either have a bad stomach bug or are falling in love. A study found that falling in love can cause you to feel sick and display physical symptoms similar to that of anxiety or stress, like sweat.
Although this feeling will probably pass once you really get comfortable with your partner, it may be a good idea to carry around an extra hanky, just to be safe.
You love their quirks
If you really get to know a person, chances are you’ll pick on the little things that make them uniquely them. And if you’re in love with them, these are probably some of the things that attract you most about them.
A study found that small quirks can actually make a person fall deeper in love with someone rather than just physical attributes because people have unique preferences. So although you may have judged your partner a little harshly on first glance, if you find that you’re suddenly in awe of their uniqueness, you might be in love.
