As we understood from previous post, freediving to depth is generally a more comfortable and enjoyable experience for the majority of freedivers than freediving to distance. This can also be explained from a scientific standpoint. ⠀ When you freedive to depth, your lung volume decreases due to increasing ambient pressure. This results in a significant increase in your blood oxygen concentration, despite the large amount of oxygen consumed during the first stage of your freedive. According to Boyle’s Law, at 20 meters depth, your lung volumeis three times smaller than at the surface. Your blood oxygen concentration is therefore three times greater. ⠀ While oxygen is transported through your body bonded with hemoglobin, there is always a small amount of oxygen dissolved in your blood plasma which enables the transfer of oxygen both into and out of your bloodstream. This small amount of oxygen dissolved in your blood plasma continues to increase as you freedive deeper. ⠀ The dissolved oxygen is used for metabolic processes within body tissues together with oxygen transported by hemoglobin, and so at depth your blood is saturated with oxygen faster and oxygen is more easily transported to your body tissues. As a result, you feel in better condition at depth than at the surface. This is known as hyperoxia and is caused by an excess supply of oxygen to your body tissues, that is, a higher than normal partial pressure of oxygen. ⠀ There are also a number of effects of hyperoxia on your body’s central nervous system. It can inhibit and suppress brain activity and consequently during a freedive, your internal dialogue halts and you withdraw. This is one of the reasons that freediving to depth gives feelings of joy, harmony, peace and a sense of reuniting with nature. ⠀ However, for this reason it is important to be prudent at depth to ensure your freedive is performed safely and conservatively. ⠀ #freedive #freediving #freedivingschool #freedivingcourses #learnfreediving #freediveindonesia #freedivingindonesia #freedivebali #freedivingbali #iamssiindonesia #iamssi #divessi #molchanovs #molchanovsfreediving #underwaterphoto #freedivephoto #underwater (at Nusa Penida / Penida Island) https://www.instagram.com/p/B_yJnKGhWxF/?igshid=1p7xvmc7ihwhs
