Coping with the death of someone you care about may be one of the hardest challenges you face, and not just in terms of your emotional health. The fact is, grief can negatively affect your physical health as well.
Weakened immune system
Your immune system protects your body against things that can make you sick. The experience of grief can actually impact the immune system. In one study, older adults who had lost a loved one had weakened immune systems compared with those who had not suffered a loss.
A weakened immune system may also lead to illness and infections. A study showed that 249 people who lost an infant or child reported a total of 404 acute illnesses during the first year after the death. The most frequent were colds and flu, headaches, anxiety, infections, depression, and angina (severe chest pains).
Grief after the loss of a loved one is normal, and the grieving process may take some time. If you decide that you need help overcoming your grief, reach out to your doctor or mental health professional for support.
