15 Physiological Signs Someone Likes You: How Many Do You Notice?

You like someone, but you’re not sure if they feel the same. Don’t listen to words, look for these physiological signs someone likes you instead.

That confusing time when you realize that you actually really like that guy or girl is both exciting and downright terrifying, all rolled into one. You wonder if they like you back because they’re not asking you out directly. And you’re not completely familiar with the physiological signs someone likes you to decode their real intentions. Of course, you want to try and make a move, because let’s face it, you want to move things along! The problem is, what if they don’t feel the same and you’re left red faced and embarrassed?

Oh, the joys of dating!

It’s very easy to listen to words and not really focus on the things people are doing. The problem with that is, people lie. Sorry, it’s true. People also say things to make others feel better. You would be far better not listening to word and instead looking more towards the things they can’t help – their physiological signs.

How to decode the subtle physiological signs someone likes you

If you want to really know if he or she is digging you as much as you’re digging them, it’s time to get medical.

Physiological signs are things you just can’t help, the things you do instinctively without trying. These are are instincts, and you can’t avoid them happening in certain situations.

For example, when you’re in a situation which scares you, you’re going to automatically react in a set way – you’re probably going to become nervous, your heart will race, you might go hot, you might start shaking, etc. This is your survival mechanism, and it has evolved from the days of the rather hairy cavemen and still quite hairy cavewomen. The same can be said for attraction. When we like something or someone, we automatically show physiological signs of attraction. [Read: The 12 rules of attraction as explained by science]

The 15 most obvious physiological signs someone likes you

If you see just one of these signs, it might be best to wait and see how things develop; if however you’re noticing more than three, that’s a pretty good indicator of the fact they’re into you too!

#1 They smile a lot around you. It’s hard to be sad and frown around someone you really like. You’re automatically going to smile, because you feel joy, and your face simply can’t help itself! In terms of the most obvious physiological signs someone likes you, a constant smile is a pretty good measure.

#2 They often make eye contact, or you notice them staring when you’re not looking. Eye contact is a definite sign of attraction, and if you notice that the guy or girl you’ve got your eye on literally has their eye on you, especially when they think you’re not looking, you can pretty much put it down as a definite ‘yes.’ [Read: The best subtle eye contact flirting moves that always works]

#3 Or, they can’t look at you. Confusing, right? Some people are a little shy naturally, or they might suddenly become shy around the people they like. If you’re noticing that he or she looks at you and then quickly looks away, perhaps like they’ve been caught doing something they shouldn’t, that’s of the clearer physiological signs someone likes you too! It depends on the person and the way they react to what is a slightly embarrassing situation.

#4 They display open body language … or it might be closed. Yet another complete confusing contradiction is the subject of body language. Generally speaking, if someone likes you and wants you to know about it, their body language will be open and not at all defensive. This could mean that their arms are by their sides, and not over their body, their shoulders are where they should be and not hunched up out of stress, and they look generally quite relaxed around you.

On the flip side, some people *shy types again* may actually display very closed body language around you for no real reason; this means they may cross their arms over their body as the main example. The best way to figure it out is to see if they do the same thing with anyone else and that should give you your answer. [Read: 18 signs to decode a guy’s body language and read his feelings]

#5 Their body is angled towards you. We tend to unknowingly lean towards the things we like, so if you’re noticing that his or her body is angled towards you, and not away from you, that’s a pretty clear sign too. Even if someone is showing closed body language out of shyness, they will probably still lean into you a little. This won’t be a move that looks forced, it will also be quite subtle, but it’s definitely there.

#6 Their cheeks are flushed. One of the clearest physiological signs that someone likes you is flushed cheeks. It’s not particularly hot, but they’re certainly going a little pink! The reason for this is thought to be the release of adrenaline, which causes an increase in blood flow. As a result, you get that pink tinge to your cheeks!

#7 They might be shaking slightly. Isn’t it great when your mere presence causes someone to lose all control and start shaking a little! Take it as a compliment, because if you see someone with flushed cheeks who has the slight shakes, it’s a very clear sign that they’re crushing on you!

#8 They stumble over their words. If someone is stumbling over their words around you and they normally don’t have an issue with it, it’s a clear sign you either terrify them or they like you! Hopefully it’s the latter.

#9 They fidget a lot. Another common physiological sign someone likes you is fidgeting. This can be messing with their hair, touching their neck, tugging on their lip, pulling on their sleeves; it can basically be any type of fidgeting motion which they wouldn’t normally do.

#10 Their pupils dilate. Okay, you’re going to have to look pretty closely to see if this is happening, but when we like someone, our pupils get larger in size. This can also be a reaction to light, so if you’re in a pretty dark environment, don’t take this is as a certain sign, but if it’s in conjunction with other signs and it’s a normal lighting kind of situation, you’re in there!

#11 They mirror your posture. The same kind of thing as leaning into you, when we like someone, we tend to mirror their posture and movements to a small degree. If he or she is standing in a similar way to you, that could be a clear sign. [Read: 13 lusty signs of sexual attraction to keep an eye on]

#12 They have a strong posture. This is more likely to be a man, but it can sometimes be a woman too. In this case, the posture is strong, because they’re trying to impress you with their strength, and in this case, manliness. A woman could be doing it to exude confidence.

#13 Their heart is beating faster. Again, pretty difficult to identify unless you get very close, but if someone likes you, their heart is likely to beat a little faster when you’re around. Look at their neck if you get the chance, can you visibly see their pulse? You might also notice they’re a little breathless as a result.

#14 They might be a little hot or sweaty. Attractive, right? If you’re noticing that he or she seems a little hotter than is necessary, it could be a clear sign that they’re feeling hot under the collar due to your presence in the room!

#15 They’re instinctively protective over you. Exhibiting protective behavior is another sign that someone likes you, because we tend to want to protect those we care about. This could be sticking up for you verbally, either when you’re around or not around, or it could be stepping into a fight. Either way, it’s a good sign.

Remember, just one or two doesn’t really tell you a huge amount, but more than three, especially when they don’t do it in anyone else’s presence and you’ve got a very clear answer coming your way!

These are 15 very clear physiological signs someone likes you. The next time you’re around that person that you’re so curious about, see how many you can tick off the list.
