Why do you feel tired after squirting (relationship between energy consumption and neurological response)

　　Understanding the causes of fatigue after ejaculation will not only help people correctly understand their own physiological reactions, but also provide sexual healthy Provide valuable reference for maintenance. Next, we will start with the energy consumption and nerve This issue is analyzed in detail by reflecting two key aspects.

Energy expenditure and fatigue

　　Energy requirements for muscle activity: During ejaculation, multiple muscle groups of the body are involved. Pelvic floor muscles, abdominal muscles, etc. will contract and relax rhythmically. This continuous muscle activity requires a large amount of energy. Taking running as an example, the repeated contraction of leg muscles during running requires energy, and the same goes for the activities of related muscles during ejaculation. The body's energy reserves mainly exist in the form of glycogen and fat. When muscle activity increases, the body will accelerate the decomposition of these energy substances to provide energy. As energy continues to be used up, the body will gradually feel tired, just like feeling tired after exercising for a long time.

　　Burden on the cardiovascular system: During ejaculation, the cardiovascular system will also bear a certain burden. heart rate It will speed up and blood pressure will increase to ensure that all parts of the body can get enough oxygen and nutrients. The heart has to work harder to circulate blood, which also uses up extra energy. Just like the heart needs to pump harder during strenuous exercise, this stress response of the cardiovascular system during ejaculation will further increase the body's energy consumption. When energy expenditure exceeds the body's reserves and recovery capabilities, fatigue ensues.

Nervous reactions and fatigue

　　Excitation and inhibition of the nervous system: During squirting, the nervous system is in a highly excited state. The brain releases a variety of neurotransmitters, such as dopamine, endorphins, etc., which cause people to feel pleasure and excitement. However, after excitement, the nervous system will enter a state of inhibition. This is a self-protection mechanism of the body, just like a spring that takes a while to regain its elasticity after being overstretched. The transition of the nervous system from excitement to inhibition can lead to a feeling of fatigue in the body.

　　Regulation of the autonomic nervous system: The autonomic nervous system is divided into sympathetic and parasympathetic nerves. During the ejaculation process, the sympathetic nerves are excited, putting the body in a state of stress, such as accelerated heartbeat and shortness of breath. After the ejaculation ends, the parasympathetic nerves will gradually take over the dominant position, which will restore the body's various physiological functions to a calm state. This conversion process of the autonomic nervous system can also have an impact on the body, causing the body to feel tired and sleepy. For example, after a stressful work situation, the body will also feel tired when it relaxes, which is similar to the regulation of the autonomic nervous system after spraying.
