Brain & Emotion
Understanding how the brain, emotions, and the body interact.
The brain continuously interprets information from the body and the surrounding environment. Emotions such as stress, anxiety, and happiness influence physiological responses through neural and hormonal signaling.
Understanding the connections between the brain and the body can help people recognize how emotional experiences affect physical health, sleep, immunity, and overall well-being. This section introduces key concepts in brain–body interaction and emotional health.
