  3. Your body can change your heart rate to benefit you. After you exercise your heart rate starts to drop. It rose the whole time you exercised. When you exercise your heart rate raises which is beneficial becaus e it is exercising you harder. When you sleep your blood rate goes down.

  5. Sleep and exercise affect pulse rate. Increased heart rate can make your heart stronger. If your heart beats extremely fast it might hurt itself.

  7. When you're excited or working out really hard your pulse rate can go up. An increase in pulse rate is helpful when you are exercising because your body needs more blood. An increase in pulse rate is harmful when you are simply excited and not exercising because that means your blood pressure is increasing and high blood pressure can cause heart attacks. And, as everybody knows, heart attacks can cause death! Dun dun daaaaaaaaah!

  8. Excercising can increase your pulse rate if you're excersising. Your heart can be stronger the more you work the heart. If your heart beats very fast it will probably hurt itself a-lot.

    Your body changes it to fit you. If your pulse is too fast then you could die.

  10. Some major factor of this that can effect the pulse rate is your activity level, fitness level, air temperature, your body position whether your standing or laying down, emotions, body size and weight, and your medication use. Abusing medicine can effect your pulse rate in ways you don't want like stressing your heart by having it beat to fast. Then causing your heart to stop all together. But there are many ranges of pulses so someone else's might be a lot higher or lower depending on their size and weight.

    Some of the things that can effect someones heart rate would be exercise, strenuous activity, and breathing heavily are all things that can result in INCREASED heart rate. Things that have the ability to decrease your heart rate would be things like sleeping, slowly breathing, meditating, and sitting still. Times when your pulse would be beneficial would be when your running away from something and it makes it so that you have more oxygen and you have more adrenalin pumping through your veins.
    A time when it would be painful would be when your arteries and veins are clogged and your heart is pumping harder and you end up getting a heart attack.

    the factors of pulse rate are the amount of exersise that you are doing. an incrase of pulse rate are, again the amoutnt of exersise you are doing. the more strenues the exersise, the higher the hart rate. it is benifitial when you are exersising because then if you didnt you would die because of the lack of blood. it can be harmful if you are just relaxing and the heart rate is to high.

  13. How hard you are working and for how long can affect your pulse rate. If oxygen cannot get to your heart because you are working so hard, you can have a heart attack... obviously harmful. Your body needs more blood per second when you are working, so a higher pulse is good.

  14. Factors that affect the pulse rate are age, body temp, pain, emotion, exercise, and blood pressure. An increase in pulse rate would be beneficial when your running away from something or in a race. It would be harmful when your pulse is already high. It could go to high.

  15. Pulse rates raise when you have large amounts of exercise or emotion, the rate lessens with the lack of these things. High pulse rate + low blood pressure is dangerous. A high blood rate can be good if you are exercising because the body needs more blood.

  16. If you're excited, or exercising very hard, your pulse increases to get the blood necessary to the parts being exercised. If you're relaxing or asleep, you're pulse is going a lot slower because you do not need that much blood, because of the fact that you aren't doing anything strenuous that requires extra blood.
    If your pulse for the average adult is below 60 or above 110, it isn't that safe. If your pulse is too you will have a heart attack, if you pulse is too slow you will probably get hypothermia, and probably die.

  17. Some factors that can affect your pulse rate are Stress ,Illness ,Over training and Caffeine. An increase in pulse rate is beneficial when in fight or flight. High pulse rate gets bad because high blood pressure can cause heart attacks.

  18. Several things that can effect your pulse to make it faster or slower are exercise, drugs, emotion, heart damage, and dehydration. During healthy exercise or strong emotion it is beneficial to have an increase in heart rate. When dehydrated, taking drugs, or experiencing heart damage such as a stroke or heart attack an increase in heart rate would not be beneficial.
