Sneezing stops heart rate. It is scientifically proven!
A lot of agents can affect heart rate, but let's say... Cocaine (accelerates the heart rate) Adrenaline (accelerates the heart rate) Potassium chloride (reduces it to zero - this is the chemical they use in executions to make the heart stop)
Stop altogether, no. There are some that have some degree of control however.
stop watch
It goes up, or if your really out of shape it can stop.
It has so far, for every human being who has died.
heart rate of 60 beats per minute
your hart would stop and you would die
How stress affects your heart rate is when you get all pumped up from being stressed it causes your heart to beat alot faster which affects tour heart rate by increasing it.
when you are afraid scared or excited adrenaline is released hence increasing heart beat rate. due to increase in heart beat rate your breathing rate increases as well. After sometime your impulse is send to your brain to stop the releasing of adrenaline and your heart beat rate decreases along with your breathing =) hope i answered your question
Yes. Using a technique called "bio-feedback", it is possible to learn to control (within limits) your heart rate. Your heart rate naturally increases during times of excitement or vigorous exercise, such as running. Your heart rate will naturally decrease when you are relaxed and tranquil, and even more when you are asleep. If your heart stops, you will be dead.
Any exercise will accelerate your heart rate, but running and jogging are perfect if that is what you wish to concentrate upon. Remember not to abruptly stop running or jogging at the end of your work out, though you may want to. It is much safer for your heart to gradually decrease your activity than to suddenly stop, so begin running or jogging at slower paces until your body has calmed before you stop.
You have a heart. It beats periodically. The rate at which it does so is your heart rate. If you don't have a heart rate, then your heart isn't beating, meaning you're dead or dying.
