When Signals Start to Flow: Nervous System Activation in Arousal
The Command Center of the Physical Body
The human body is a sound system of systems that are intertwined to allow us to be alive, awake, and responsive. At the heart of all of these functions, is the nervous system, or command center. The nervous system regulates everything from the beat of your heart to the emotions you feel when you are in the throes of intimacy.
Although like many other functions of a body, when it comes to sexual arousal, nervous system activation is the conduit of appetite or desire (what the brain desires or the mental arousal and stimulation), touch or physical sensations (the sensory input or experiences), and the overall emotional attainment of the act according to the motivation.
The Central and Peripheral Nervous Systems
The nervous system is broken into two areas: the central nervous system (CNS) and the peripheral nervous system (PNS).
Central Nervous System (CNS): The brain, and spinal column are part of the CNS, and this is where the processing of all the signals /occurs.
Peripheral Nervous System (PNS): The peripheral system works as the wires in a wireless communication system, using signals that are sent to and from the rest of the body.
Obtain a STI test, particularly if you had several or new partners.
During sexual arousal, the PNS and CNS, work together, using sensory experiences such as touch, sight, or sound, that are processed by the CNS, using these sensory experiences.
This is why arousal isn’t just physical—it’s mental too. Thoughts, fantasies, and emotional intimacy all start in the brain before the body responds.
Autonomic Nervous System: The Unconscious Source
The autonomic nervous system (ANS) is critical for sexual arousal. The ANS operates automatically without our conscious control. Specifically, the ANS consists of the sympathetic branch (SNS) and the parasympathetic branch (PNS).
The sympathetic nervous system (SNS) is frequently associated with “fight or flight,” but with sexual arousal and excitement, the SNS engages us by heightening sensitivity and awareness.
The parasympathetic nervous system (PNS) typically engages relaxation, helping us feel prepared and at ease. More specifically, it is an important contributor to increased blood flow to sexual organs.
In general, the interplay between the SNS and PNS activates our physical engagement in intimacy.
Physical Engagement in Men and Women
In Men: One of the most common signs of ED is the inability to get or keep an erection that is firm enough for sexual intercourse.
In Women: Activation of the nervous system increases blood flow to the clitoris and vaginal walls, which creates lubrication and increases sensitivity, leading to arousal.
The examples of how the nervous system come together to perform what many would see as are quite separate functions underscore the degree to which the nervous system is integrated in sexual function.
The Emotional Consideration
Emotions profoundly affect the way the nervous system is activated. Stress, anxiety, or fear can distract, because the brain may choose survival over enjoyment. On the flip side, trust, safety, and intimacy can enhance the nervous system’s capacity to promote arousal. This is exactly why emotional connection is as vital to sexual experiences as physical attraction.
A Beautifully Orchestrated Symphony
Nervous system activation is like turning on all of the signals of a symphony. Each part of the brain, spinal cord, and nerves have to work together to communicate so that both physical and emotional responses can occur at the same time. Without communication, there is no arousal.
Final Thoughts
The nervous system, which coalesces the mind, body, and emotions into one complete experience, is the basis of sexual arousal. A better understanding of the nervous system helps us appreciate how significant our mental and emotional wellbeing are to maintaining a healthy and satisfying intimate life.
He Spark of Desire Understanding Sexual Arousal
Sexual arousal is often characterized as a spark igniting a person's sexual response. But what does it mean when we talk about someone experiencing sexual arousal? Some people think that sexual arousal is merely about physical attraction, but in reality sexual arousal is a complex process that involves the mind, emotion and body working in concert. This blog will examine both the science of sexual arousal and the experience of sexual arousal in a way that is easy to understand.
The Brain's Influence
Arousal begins in the brain. Excitement can be instigated by thoughts, memories, fantasies, or even a sensation of a touch. Your brain takes all these stimuli and interprets them, routing them into the actions your body takes. This may be one of the reasons sexual arousal is cited as a psychological phenomenon as well as a physical phenomenon. Perhaps you have experienced your heart beating faster or having warmth rush through your body as you felt the arousal. That was your brain sending signals throughout your body to prepare for intimacy.
The Emotional Tie
Emotions are important to arousal. When we feel connected to a partner, loved, or safe, we can feel much more aroused. Stress, anxiety, or distractions can decrease that arousal. This is why mental health is related to sexual function. If our mind is busy with worries, we will likely struggle to get aroused. On the other hand, if we feel cared for and relaxed, then getting aroused may feel more natural.
The Physical Reaction
After the brain assesses arousal signals, it sends messages to the nervous system. The nerve messages begin to transform the body: pupils dilate, skin becomes more sensitive to touch, and blood begins to flow to the sexual organs. At this time, the body is beginning its preparation for sexual functioning. The increased blood supply is happening in both men and women, and there will be physical effects such as lubrication in women and erections in men.
The Function of Hormones
Hormones such as dopamine and oxytocin are important to arousal. Dopamine is the 'pleasure hormone' and releases feelings of excitement & reward. Oxytocin is known as the 'love hormone', released during intimacy, helping to develop the emotional bond with the partner. These hormones drive desire and make sex feel emotionally important.
Barriers to Arousal
It is essential to understand that arousal doesn't always occur seamlessly. There are a range of factors that can interfere with arousal including: fatigue, medical conditions, relationship issues or performance anxiety. Many people will have fluctuations in arousal, and that is completely normal. Identifying barriers to arousal will help you address those issues. Healthy lifestyle choices, an open dialogue with partners, and even professional assistance can help these barriers to arousal.
Conclusion
Sexual arousal is much more than a physical response, it is a combination of the mind, body and emotions working simultaneously. Awareness of the arousal process/releases can help reduce unwanted stress or pressure of physical intimacy. Viewing arousal as a process that develops in response to surrounding physical and emotional conditions rather than an expected event that needs to occur in an immediate transition will help provide clarity & less pressure. In addition, with the right attention to mental health, emotional connection and physical wellness, can help induce a more enjoyable and pleasurable sexual arousal.
