Deep Sea Diving: Is Your Heart Ready for Underwater Adventures?

You dive headfirst into an aquatic adventure but remember that your heart dives first. The heart plays a pivotal role in deep-sea exploration. The cardiovascular system is most influenced by external water pressure. The deeper you dive, the higher the pressure your body faces. There is more poor circulation in limbs, and the heart maintains that pressure. It works tirelessly to pump oxygen-rich blood to our muscles and vital organs. So, the heart has to work at its total capacity. You can understand how the heart must be healthy for this enjoyable diving experience. It's a safe sport until you keep your heart health a priority.

Why Heart Health is Important in Deep Sea Diving

At the dry land, your heart buzzes along, keeping you alive and well. Your oxygen supply is limited in water. Your heart must efficiently use every bit of oxygen from your reservoir. Under the crushing pressure of the deep sea, it faces a persistent challenge. When you dive, your body undergoes several physiological changes, so your heart health matters to enjoy marine life:

  • Increased Oxygen Demand

Swimming is a physically demanding activity that requires perseverance and strength. At the same time, managing diving equipment requires significant effort. Your body tries to put your heart to work at the best capacity to meet the oxygen needs.

  • Reduced Heart Rate

The mammalian diving reflex stimulates the vagus nerve, which lowers the heart rate. This reflex is important in mammals to reduce the consumption of oxygen. However, in humans, it is very systematic as blood pressure increases, thus resulting in a load on the heart.

  • Increased Blood Volume

When you dive, water exerts pressure on your body and, thus, on blood vessels.  It increases the blood volume in your chest, boosting central venous pressure and increasing cardiac output to circulate the larger blood volume.​

  • Change Of Temperature

There is always a sharp drop in temperature that can cause coronary artery spasms and arrhythmia. This can result in a heart attack or cardiac arrest.
