10 health benefits of SCUBA diving

Updated: Apr 9, 2021


  1. Gaining strength and flexibility: As you move throughout the water during the dive, your muscles tend to work harder than they would if you were outside the water. This is due to the resistance of the water, but also the current. The more you dive and swim, the more your muscles lengthen, build strength and develop endurance as well as flexibility. Scuba diving and swimming through the water can not only strengthen your legs it can also help to build up your core strength, which is important for a good overall posture in your everyday life.

  2. Breathing: Breathing whilst diving is slow and deep, which is essential when conserving and optimizing your air consumption. During a dive, you breathe in and tend to breathe out slower which reduces the heart rate, promoting calm. Steady breathing also reduces the risk of a lung expansion injury, reduces mucus build-up and has actually been known to help with existing conditions such as asthma.

  3. Can lower blood pressure: When first diving into the water, a divers heart rate might spike, and their blood pressure will rise slightly. This may be due to excitement, adrenaline and even the cold water. For most dives, we usually find ourselves in water that is lower than our body temperature. When our body is immersed in cold water, our blood vessels on the surface of our bodies tend to constrict to conserve heat for our internal organs, which may cause our hearts to race. Once we warm up throughout the dive, our heart rate reduces as well as our blood pressure. The slow and deep breathing technique that we learn to do during our open water dive course can help lower your blood pressure and keep you calm throughout the dive. If however, you suffer from high blood pressure, then seek the advice of a medical professional before attempting to scuba dive.

  4. Maintains and increase fitness levels: Before we scuba dive, a diver should already have a good level of fitness to not exert the body too much throughout a dive, which could put the diver at risk of DCS (Decompression Sickness). Scuba Diving can be quite unpredictable and because of this, you may find yourself swimming against the current for a short amount of time. This repetitive movement of the legs against the resistance of the water can help to maintain as well as increase your fitness levels (it is certainly better for you than sitting on the sofa watching TV)!

  5. Travelling to warmer climates: It is, of course, possible to dive in colder climates, however usual dives include travelling to warmer parts of the world. With warmer parts of the world bring holidays, adventure, excitement and experiences, which can only do great things for your body, mind and soul.

  6. Healing effects of the water: The water has many healing effects, one of which is the way it brings you back to feeling like you are in your mother’s womb. This promotes feelings of security, well-being and happiness. In addition, being in salt water for long periods of time can cause your body to dehydrate. This means that you tend to drink a lot more after the dive, which means that you are replenishing your cells, receiving all the benefits of water both externally and internally.

  7. Interaction with marine life: When exploring the marine life surrounding you on your dive, your body is flooded with excitement, wonder and awe. Seeing the sheer variety of fish, corals and critters are enough to put anyone in a good mood. It has in fact been proven that seeing certain colours can affect the brain in many different ways, for example helping to change and improve your mood. Scientists believe that if we are subjected to bright and intense colours, similar to what we might find surrounding reefs, can help to promote feelings of happiness and upliftment. In addition, the colour blue has been known to induce a calming effect on the body.

  8. Exposure to sunlight: The body needs to
