Vaccination, handwashing, and similar strategies can reduce the risk of illness, including the chance of getting shingles. However, once a person has shingles, there is no clear evidence that reducing exposure to triggers will make the rash heal more quickly.
A person taking drugs that weaken the immune system should contact their doctor about whether to continue these drugs. They should also avoid starting or stopping any new medication without first talking with a doctor.

Some examples might include avoiding:
- sexual contact involving friction if the rash is near the genitals
- manicures or pedicures if the rash is on the hands or feet

- saunas or high heat, since sweat might irritate the rash
- swimming, contact sports, and close contact that could spread the virus to vulnerable people
- massage, acupuncture, or other activities directly on or near the rash
Washing hands thoroughly, especially after contact with the rash, can help prevent spread.
