Air pollution may promote asthma and worsen lung diseases by altering immune regulation and increasing oxidative stress, according to recent research on mice.

"There was also a study in mice that showed chronic stress may accelerate the greying of hair." Scalp itch can also be a manifestation of stress, anxiety or depression, Cobb adds.

When injected, this virus increased the levels of CB1 receptors in the mice's astrocytes but not in their neurons. These mice were then subjected to chronic social stress.
