Am I not breathing enough?

Your body is trying to get rid of excess heat.  It dilates the capilaries in your skin to allow an increased blood flow so that the blood cools faster.\n\nYou probably don't sweat enough, or it's very humid when this happens.

you may just have a high metabolism...asthma may be a bigger problem if you were overweight not under weight\n\nYou can be overweight or underweight and still be malnutritioned, if you eat the right amount of food and not too much junk food then you should be ok.  If you are fatigued and feel sluggish a lot maybe you should change your diet and eat the recommended daily allowance of fruit, veggies, etc

I think you might be suffering from some milder form of hyperventilation, that can cause symptoms very much like the one you describe and is often mistaken for some sort of affliction of the heart.\nYoga can help you here, or some form of breathing-therapy.\nGood luck and good health!

Are you having a anxiety attack. I have had them over fear for my children several years back. Then again when I found out my Ex-Fiance was terminal. I totally freaked out. My skin was all prickly tingly numbness I couldn't  or had a hard time breathing. If you have ever done lamosse (sp) breathing it helped me allot. The Dr gave me a mild sedative but I don't like pills so I do the breathing. You need to relax, if it persists and is making you nervous push the issue with your Dr. change Dr's if you have to. But follow through and be persistent till you get the answer you need. Good luck

Along with what the others have said, breathing in your nose and out your mouth, time your breathing with your steps, this will help you regulate. IE: Three steps breath in, three steps breath out, or find a regulation that works for you. As long as you find a pace that works well for you that is what matters. Most often when you feel tired it isn't because your muscles are tired, but that they aren't getting enough oxygen to work properly.

Blah, blah, blah.  You know, with every breathe you take, you're one breathe closer to death.  Better stop breathing!

Too much stress and not enough exercise come to mind

Wow see a doctor, you might have exercise induced asthma or something else, maybe with your blood sugar. Please tell your parents or guardian and definitely see a doctor!

If you're not sweating and you don't feel like your lungs are working hard you are probably not doing enough. You would be better off working out for 30 minutes at a higher intensity. Every body is different and I can't tell you what is going to work for YOU, but bottom line is you need to listen to your body. I would try maybe running, either on a treadmill or just on the street, and make sure you are working at a level appropraiate for you. Ignore the machine's readings. People get too caught up in that and they are so general. You need to raise your body temp enough to break a sweat and you need to be breathing hard enough that you can still carry on a conversation but feel like you would rather not. That's the rule that I use and it works for me.

Air out your room and get out of your room and into some fresh air for a while. If your breathing gets worse then go to your local ER.

You must not be inhaling.\n\nCoach

YES!  \nAbsolutely it does!\nYou are not taking in the proper amount of oxygen therefore not oxygenating your blood stream/muscles/lungs properly.

Yes you still have to breathe for them.  \nCPR is like artificial heartbeat and breathing.  \nIf you are interested, maybe you should take the certification class.

It sounds like you have poor circulation. I will advise walking like 15 minutes a day. Maybe more if you get used to it. And take B12 is also good for you.
