Active Dehydration during Freediving
Freediving is a challenging and strenuous activity that requires a high level of physical and mental fitness. Dehydration, which is the state of insufficient water in the body, can have detrimental effects on physiological processes and physical performance. This review aims to provide an overview of the physiological mechanisms associated with dehydration in the context of freediving, as well as its effects on freediving performance. Additionally, the review discusses strategies for maintaining hydration during adventure freediving and suggests areas for future research. The review highlights the importance of adequate hydration for optimal performance in freediving, and the need for further research in this area.
Freediving is a form of underwater diving that relies on the diver’s ability to hold their breath, rather than using a breathing apparatus such as scuba gear. Freedivers may use fins and other diving equipment to help them swim deeper and faster, but they do not carry air tanks or use regulators to breathe while underwater.
Physiological Mechanisms of Dehydration in Freedivers
The role of water in the body is essential for maintaining homeostasis and proper physiological functioning. Dehydration, which occurs when there is a negative balance between fluid intake and output, can lead to a range of physiological changes, including decreased blood volume, increased heart rate, and impaired thermoregulation. Factors that can influence dehydration in freedivers include environmental conditions, individual factors such as body composition and physical fitness, and diving practices. In response to water scarcity, the body can initiate a range of adaptations, including changes in urine production and blood flow regulation, to maintain homeostasis.
Effects of Dehydration on Freediving Performance
Dehydration can have significant effects on physical and cognitive performance in freedivers. Studies have shown that dehydration can lead to reduced endurance and strength, impaired cognitive function, and increased risk of decompression sickness. The mechanisms underlying these effects are complex and involve alterations in cardiovascular function, fluid balance, and metabolic processes. Additionally, dehydration can have psychological effects, such as increased anxiety and reduced motivation, which can further impair performance.
Strategies for Maintaining Hydration During Adventure Freediving
Maintaining adequate hydration is essential for optimal performance in freediving, particularly in the context of adventure freediving. Pre-dive hydration strategies, such as increasing water intake prior to the dive, can help prevent dehydration. In-dive hydration strategies, such as consuming fluids during the dive, can also help maintain hydration levels. Post-dive hydration strategies, such as consuming electrolyte-rich fluids, can help replenish fluids and prevent dehydration-related complications. However, these strategies have limitations, such as the need for access to fluids and the risk of gastric upset.

Future Research Directions
Despite the importance of hydration for optimal performance in freediving, there is still a need for further research in this area. Areas for future research include the development of more effective hydration strategies, the impact of dehydration on specific aspects of freediving performance, and the potential long-term effects of dehydration on health and well-being in freedivers. Additionally, more research is needed to understand the mechanisms underlying the effects of dehydration on freediving performance, as well as the factors that influence individual responses to dehydration.
Dehydration is a critical concern for freedivers engaged in adventure diving. It poses a significant threat to their safety and can lead to various adverse effects on their physiological and cognitive functions. The severity of dehydration can vary depending on various factors, including the environment, diving duration, and individual factors. However, even mild dehydration can lead to a reduction in physical and cognitive performance, leading to a higher risk of accidents and injuries during diving.
Therefore, it is essential for freedivers to adopt adequate hydration strategies before, during, and after diving. These strategies may include drinking sufficient amounts of fluids, avoiding diuretics such as caffeine and alcohol, and monitoring hydration levels regularly. Additionally, it is crucial for divers to understand the signs and symptoms of dehydration and take necessary steps to address it promptly.
Future research can focus on exploring additional hydration strategies that may be beneficial for freedivers, including the use of electrolyte-infused drinks, water intake schedules, and pre-dive hydration protocols. Furthermore, understanding the impact of dehydration on divers with different levels of experience and training can help develop more targeted and effective prevention and intervention strategies.
In summary, adequate hydration is crucial for the safety and performance of freedivers during adventure diving. By adopting appropriate hydration strategies and understanding the risks and consequences of dehydration, divers can enhance their physical and cognitive abilities and enjoy a safer and more enjoyable diving experience.

Apnea is the temporary suspension of breathing. In the context of freediving, apnea refers to the act of holding one’s breath while underwater. Freedivers often practice apnea in order to increase their ability to hold their breath and to dive to deeper depths.
