According to
Harvard Health, scientists are looking into the relationship of stress on the immune system. While it's difficult to determine the exact impact of stress, short-term stressors, such as panicking about the virus, might not be so damaging as long-term stressors such as relationship issues or job-related stress that may impact the immune system. Where possible try and cut the stress from your life, which is easier said than done, but prayer and moments of reflection are helpful to lean on.
