Recreational diving has become an increasingly popular sport for women. Recent statistics show that the number of female scuba divers increases every year with about half of all new certifications being women.
It has been a longtime misconception that women were at a greater risk for Decompression sickness (DCS) than men. However, more recent and specific studies conducted in the area of recreational sport diving revealed that this parable may be inaccurate when women are conducting no-decompression dives. There are other myths that may create a sense of apprehension in females interested in taking up scuba diving such as the increased likelihood of a shark attack during menses or rupturing breast implants while diving at deeper depths. There are, however, real health concerns in recreational sport diving that women should take the necessary precautions to prevent and / or avoid.
Physical Differences Between Men and Women Relating to Scuba Diving
It is a known fact that most women have smaller lungs, a greater percentage of body fat, a lower aerobic capacity and less upper body strength than men. These physical differences inadvertently have some effects on diving. Because women generally have smaller lung volume than men, they tend to use less air per minute than men. This is usually apparent when diving with a group of male and female divers. Depending on the level of experience, in addition to gender, air consumption among women will usually last approximately 10 to 15 minutes longer than men?s. Apart from pregnancy, the useful differences between men and women when diving are not at all substantial.
Women and Decompression Sickness
Women have on average 10% more subcutaneous fat than men. Since fat tissue can hold five times more nitrogen than blood, it has been suggested that women might be more susceptible to DCS than men. Although studies have taken place in this area, concrete facts and results are inconclusive. Some studies have suggested an increase in DCS among women, while others have not found any difference. In short, as a result of inconclusive studies and lack of any perceived gender-related problems by professionals in the field, it is implied that there is no increased risk of DCS among female divers.
