How Stress Affects Your Heart Health

Stress is a normal part of life. Short-term stress can help the body respond to challenges. But long-term stress can affect heart health. Learning how stress affects the body can help people take steps to protect their hearts.

The Body's Stress Response

When a person feels stressed, the body reacts right away. This is often called the “fight or flight” response. It helps the body deal with danger or pressure.

During stress, the body may: 

• Increase heart rate: The heart beats faster to move more blood and oxygen. 
• Raise blood pressure: Blood vessels tighten, raising blood pressure. 
• Release stress hormones: Adrenaline and cortisol help the body respond to stress. 

These changes can be helpful for short periods. When stress happens often or lasts too long, the heart works harder
than it should.

Long-Term Effects of Stress on the Heart

Stress that does not go away can strain the heart and blood vessels. The body may remain tense for long periods.

Over time, stress may lead to:

• High blood pressure: Blood pressure may stay high, which strains the heart.

• Higher risk of heart problems: Stress can raise the risk of heart disease or stroke.
• Inflammation: Long-term stress can increase inflammation throughout the body, which can affect heart health. 

Managing Stress to Support Heart Health

Lowering stress can help protect the heart. Small daily habits can help the body relax.

Helpful ways to manage stress include: 

• Movement: Walking, stretching, or light activity can lower stress. 

• Calming habits: Slow breathing, quiet time, or gentle relaxation can help. 
• Support: Talking with friends, family, or support groups can ease stress. 

Managing stress does not mean removing it completely. Taking small steps each day can help the heart stay healthier over time.
