Arterioles dilate in warm environments (vasodilation). Dilate means to open. Vasodilation is a process in which the increased blood flow through the dermis brings excess heat close to the body surface to be radiated to the environment. Arterioles constrict in cold environments (vasoconstriction). Constrict means to close. Vasoconstriciton is a process in which the decreased blood flow through the dermis keeps heat within the core of the body. Both take place to maintain homeostasis.
In stressful situations, vasoconstriction takes place. It will shunt in the dermis or redirect blood to more vital organs such as the muscles, heart and brain.
Adrenocorticotropic hormone (ACTH) is essential for the stress response, as it stimulates the adrenal glands to produce cortisol, which helps the body respond to stress by regulating metabolism, immune function, and blood pressure.
The sympathetic nervous system responds to stress by releasing adrenaline and increasing heart rate, blood pressure, and breathing rate to prepare the body for a "fight or flight" response.
The endocrine system in the human body is responsible for producing and releasing hormones that regulate various bodily functions, such as metabolism, growth, and reproduction. These hormones are secreted by glands like the pituitary, thyroid, and adrenal glands, and they help maintain the body's internal balance and respond to stress and changes in the environment.
The sympathetic nervous system is responsible for activating the body's fight-or-flight response during times of stress. It releases adrenaline and other stress hormones, increasing heart rate, blood pressure, and breathing rate to prepare the body to respond to a perceived threat.
The sympathetic nervous system is activated during stress, leading to the release of adrenaline and other stress hormones. This causes an increase in heart rate, blood pressure, and breathing rate, preparing the body for a "fight or flight" response. This heightened state of arousal helps the body to respond quickly to the stressor.
Collagen fibers makes up 75% of the dermis, which is the inner layer of skin that protects the body from physical stress, it also contains elastic fibers, and ground substances.

Stress response
The epidermis is the outermost layer of skin forming a waterproof, protective wrap over the body's surface. The dermis is the layer beneath the epidermis which is made of connective tissue that provides cushioning from stress and strain.
