Sympathetic Nervous System(SNS)
Massage therapy has been shown to have a positive impact on the hypothalamic-pituitary-adrenal (HPA) axis and the sympathetic nervous system (SNS). Studies have found that massage can reduce cortisol levels, which is a hormone associated with stress, and increase levels of serotonin and dopamine, which are neurotransmitters associated with feelings of well-being. Additionally, massage can decrease heart rate and blood pressure, which are indicators of the body's stress response.

Stress is a term that refers to the physiological response of an organism to any factor that disrupts homeostasis. It has been a part of human life since the beginning of animal existence, arising from pain, fear, or exposure to temperature extremes. In the 21st century, psychological stress has become highly prevalent, and almost everyone experiences its negative impacts. Chronic stress has been linked to the exacerbation of many diseases, including cancer. Two major pathways can be activated in response to stress: the (1)hypothalamic pituitary adrenal axis (HPA) and the (2)sympathetic nervous system (SNS).
(1) The hypothalamic-pituitary-adrenal (HPA) axis is a complex system that plays a crucial role in regulating our body's response to stress. The HPA axis involves the hypothalamus, pituitary gland, and adrenal glands, which work together to produce and release hormones that help us cope with stress. Understanding the HPA axis can provide valuable insights into how stress affects our health and well-being.

(2) The sympathetic nervous system is responsible for the body's "fight or flight" response. When activated, it prepares the body to respond to perceived threats by increasing heart rate, dilating pupils, and releasing adrenaline. This response can be helpful in dangerous situations, but chronic activation can lead to negative health effects.
