A study of young female university students in Saudi Arabia has found that symptoms of anxiety and insomnia are associated with reduced levels of natural killer cells, key components of the immune system’s early defense. The findings suggest that psychological stressors may be linked to weaker immune responses, though the research shows correlation rather than causation and is limited to a small, specific population.
A new study shows that slowing breathing rates can reduce anxiety-like behaviors even without any conscious effort or belief in its effects. Researchers used mice to demonstrate that the benefits come from physiological changes rather than placebo. The findings were presented at a summit in Los Angeles earlier this month.

A randomized clinical trial found that 24 minutes of specially designed music paired with auditory beat stimulation significantly lowers anxiety symptoms. Researchers at Toronto Metropolitan University tested various listening durations on 144 adults with moderate anxiety. The 24-minute session provided the strongest benefits.
