Study Links Anxiety and Insomnia to Weakened Immune System in Young Women
A recent study published in the journal Frontiers in Immunology has identified a potential link between anxiety, insomnia, and a weakened immune system. Conducted by Renad Alhamawi and her team at Taibah University in Saudi Arabia, the research focused on 60 female students aged 17 to 23. The study found that 75% of participants reported symptoms consistent with generalized anxiety disorder (GAD), and 53% reported insufficient sleep. Blood tests revealed that those with anxiety symptoms had 38% fewer natural killer (NK) cells, which are crucial for the body's defense against infections and cancer. The study highlights a correlation between anxiety, sleep deprivation, and reduced NK cell levels, although a causal relationship has not been established.
