My wife suffer arthritis problem.

Yes, it can if you're not careful. Exercises that involve heavy lifting or high impact can put extra stress on your spine and make the condition worse. However, gentle exercises like walking, swimming, or stretching can actually help relieve pressure on your disc and strengthen the muscles around it....

Yes, stress can cause heart palpitations because when you are stressed, your body releases a hormone called adrenaline which makes your heart beat faster. But, it could be something else too like too much caffeine or alcohol, certain medications, asthma inhalers, dehydration and other health issues.....
