What does it mean when my heart beats really fast when I walk into a crowded room?

Well, dont worry, this happens to me as well; such a reaction may be linked to feelings concerning anxiety, nervousness, discomfort, and such; its important to understand that feeling this way is okay, its normal, and it happens; just try and calm down, breathe regularly, and try to keep your composure. Be confident and regain control, it will pass; dont be fearful of such sudden feelings either; you are strong:D

You're experiencing anxiety. You feel nervous and scared of what might happen. You also feel uncomfortable for being around too many people.

From my experience with social anxiety, it was because of my nervousness. I felt as if I was getting an anxiety attack and my heart would race and I wouldn't be anle to breathe. I just didn't like being around a lot of people.

It's a manifestation of social anxiety. Personally, if this happens I'd recommend just walking out of the room before it gets worse, wait to calm down a little, and then try and go back. Try and ease yourself into it.

Does this happen every time you walk into a crowded room? Does it matter whether you know the people in the room or not? I'd like to hear more.

It means that you're a normal person like everyone else. Also, it means that you're focusing on your physiological body too much which might not aid you in this case. Rather than focusing on your heart rate, take a deep breath, focus on your breath and know that you are in control of your body. And self assure yourself that "I AM OKAY".

It means you are concerned what people are thinking and how they will react. What you must remember is that they are thinking the same thing, so relax and enjoy yourself.

It means you may be experiencing some anxiety or nervousness about going into those crowded rooms.

It usually means you are nervous/anxious. When you feel like that you tend to get a racing heart rate, difficult to breath maybe and feel sick and many other symptoms you weren't aware of that can be caused by Anxiety. It basically means your brain sees fear and goes into danger mode and making your body think it is in danger when really you are not. Anxiety can be handled and you can cope with it. Meditation and breathing exercises really help but some others would disagree. Just find a way that helps with anxiety that suits you :) Talking to a friend, family member or therapy can help a lot!

Sounds like a touch of anxiety. Most people feel a heightened sense of excitement (a rush of energy) when engaging with a bunch of people at once. For some of us it can be slightly more unpleasant and feel just like stress or worry (anxiety).
