Stress and anxiety are both wholly natural parts of life, but they can be harmful to your well-being if poorly managed. Long-term stress can result in inflammation, and it can also cause lasting damage to your immune system more generally.To manage your stress or anxiety sufficiently, in a way that ensures you avoid any lasting damage, it’s important to practice habits that are naturally calming. These can include maintaining a gratefulness journal, practicing meditation and mindfulness, and exercising regularly.
