Diving into the water without an oxygen tank is called ‘free-diving.’ It is a form of apnea diving in which divers must hold their breath for an extended period while diving deep into the water with just one breath of oxygen. The difficulty in holding the diver’s breath during this time is not due to a lack of oxygen but rather an increase in carbon dioxide concentration. In other words, if you keep your heart rate low and your metabolism slow, you produce less carbon dioxide, which allows you to dive for a longer duration. The only way to maintain a low heart rate is to remain as calm as possible. Maintaining calmness has numerous benefits in life. - Joseph’s “just my thoughts”
Adenosine is released when our body is tired, making us feel exhausted. Rest serves as a complementary action for fatigue rather than a mere exercise of will to “take a rest.” The caffeine in coffee prevents the sensation of fatigue by interfering with adenosine’s binding to neuronal receptors in the brain. It doesn’t eliminate the substance that causes fatigue; it simply disturbs the senses. Humans have negative elements, and while removing them is the fundamental solution, they often misunderstand the impact of caffeine on their senses as a remedy. Ultimately, without rest, a person can become overwhelmed. Problem-solving should begin with acknowledging reality, but if we view illusion as a solution, there will be no answers. - Joseph’s “just my thoughts”
