Have you ever wondered why you feel quite tired after an exciting, adrenaline filled day? If you are ever in need of a quick boost of energy, give yourself a good scare. That will get the heart pumping. Your body will release a hormone called adrenaline in situations of stress, fear, anger or high excitement to give you that sudden boost of energy and strength. That’s because adrenaline’s main function is to prep your body for fight or flight.
Getting your heart pumping with a burst of adrenaline is a short-lived affair.
Guess where adrenaline is ‘stored’ in the body? It lives in the kidneys! When adrenaline is released, the heart rate increases. Air passages and blood vessels in the body dilate, allowing more oxygen to be carried through and raising the blood pressure slightly. The heart pumps harder, pushing more blood out with each pump to reach muscles.
Once the emergency is over, the heart rate returns to normal. If excessive adrenaline is produced, for instance when a person suffers from panic attacks regularly, the resulting increase of adrenaline in the blood can disrupt normal bodily functions, leading to heart disease and other potential medical problems such as depression, obesity, memory loss, digestion problems and so on. It is advisable to visit a doctor and get on to managing the problem as soon as possible.
If the heart is racing thanks to exercise, you can heave a major sigh of relief and give yourself a pat on the back. Well done!
The heart is the most important organ in the body and it pays to take care of it well. Exercise gets the heart racing in a good way because even the thinnest person has fat build-up around some of the organs in the body. By getting heart-fit, you are minimising the risk of having fat build-up wrapped around your heart. The side benefits include a boost in the metabolic rate, increased energy levels and living longer in general. There is also a research out there that says women who lead an active lifestyle are 30 percent less likely to develop breast cancer.
We don’t need to be Cathy Freeman to achieve heart fitness, a start in leading a more active lifestyle is the first step.
