Due to increased sympathetic stimulation of efferent neurons from the cardiac accelerator center in the brain medulla. This results in an increased firing rate from the Sinoatrial Node and increased conductivity leading to greater contractility.
In decreases the heart rate.
No! they are cold blooded.
When someone is holding their breath, oxygen levels decrease. Heart rate will then increase to try to keep the oxygen flowing.
when u jump into a cold lake your heartrate immediately drops thats why some people can die when they jump into cold water imeediately as your blood cannot produce enugh oxygen it cant produce enugh oxygen becus when u jump ijto a cold lake u hold ur breath
I just came across some information on the vagus nerve. If it is stumulated, - which can be done by swallowing or by having cold water on or around your face - it can cause the heart to slow and even cause fainting. http://www.thesurvivaldoctor.com/2012/10/25/fast-heart-rate/ http://en.wikipedia.org/wiki/Vasovagal_response
Drinking cold water can have a temporary effect on the heart rate, causing it to temporarily increase. This is because cold water can stimulate the vagus nerve, which regulates the heart rate. However, this effect is typically short-lived and not harmful for a healthy heart.
the heart rate decreases, to a low rate oof 20 to 30 beats per minute. especially in cold water.
The lower the temperature the faster the heart beat which made us shiver.

you heart beat faster when you're doing heavy work. as you release energy it also pump more blood. When a cold water place in you, it makes you feel relaxed, and it minimizes your heart beat.

Your heart rate slows down as your body is trying to preserve energy in order to keep internal organs at appropriate temperature.

Yes, cold water can shock your system when you suddenly immerse yourself in it. This is because the sudden change in temperature can cause your body to react by increasing your heart rate and breathing rate, which can be dangerous if not managed properly.
The hand grips on the units have pulse sensors that allow the recording of your heart rate.
