5 Must Know Facts For Your Next Test

1. Chronic stress can negatively impact brain function, leading to disorders such as anxiety and depression.
2. Stress influences eating behaviors, often resulting in poor dietary choices that can exacerbate neurological issues.
3. The hypothalamic-pituitary-adrenal (HPA) axis plays a crucial role in the body's response to stress by releasing cortisol.
4. Nutritional deficiencies, particularly in vitamins B6, B12, and folate, can worsen the effects of stress on the nervous system.
5. Omega-3 fatty acids are known to help mitigate the effects of stress on brain health by supporting neuronal function.
