How can stress impact physical health?

Stress can have a significant impact on physical health, particularly by causing headaches and muscle tension. When a person experiences stress, their body releases hormones like adrenaline and cortisol. These hormones can lead to a state of heightened alertness, which may cause muscles to tense up as part of the body's fight-or-flight response. Prolonged stress can keep these muscles in a contracted state, resulting in physical discomfort, including tension headaches and other muscular aches. Additionally, chronic stress is associated with various long-term health issues, such as cardiovascular problems, but the immediate effects often manifest as headache and muscle tension, making this answer particularly relevant.
