Feeling cold when you're sad or mad is a common physiological response that can be attributed to the body's stress response system. When you experience intense emotions like sadness or anger, your body undergoes various changes, including the activation of the sympathetic nervous system, which is responsible for the body's "fight or flight" response.
During the fight or flight response, the body prepares to respond to perceived threats or stressors by releasing certain hormones like adrenaline and cortisol. These hormones trigger a series of physiological changes aimed at providing the body with extra energy and alertness to deal with the situation.
One of the effects of the sympathetic nervous system activation is the redirection of blood flow away from the skin's surface and extremities towards the body's core. This process is known as vasoconstriction. The goal is to conserve heat and ensure that essential organs receive adequate blood flow and oxygen in case of a potential threat or need for physical exertion.
As blood flow shifts away from the skin, you may feel colder, even if the ambient temperature remains the same. The sensation of coldness can be more noticeable in your hands and feet, as these are the peripheral areas most affected by vasoconstriction.
In addition to vasoconstriction, stress and strong emotions can also cause tense muscles and increased muscle activity, which can lead to a sensation of chills or shivering, further contributing to feeling cold.
It's worth noting that individual responses to emotions can vary. Some people might experience heightened warmth or sweating during emotional arousal, while others might feel cold. The autonomic nervous system's response to emotions can be different from person to person.
If you find that you frequently experience feeling cold in response to emotions, it is generally considered a normal physiological reaction. However, if you have concerns or experience other symptoms that are distressing or disruptive, it's always a good idea to discuss them with a healthcare professional to rule out any underlying medical issues.
