The hypothalamic-pituitary-adrenal axis (HPA axis) is the hormonal communication system between your brain and adrenals that regulates your stress response. When this system is functioning optimally, you feel awake and alert during the day, easily fall asleep, can handle stress as it comes along, and recover from stress shortly after an acute episode.
When it’s not functioning correctly, typically as a result of high and prolonged stress, you don’t feel well, and you may experience circadian rhythm and sleep issues. Here are some ways to support a healthy HPA axis:
• Take time for yourself each day – actively counteract burnout with boundaries and self-care
• Eat breakfast (with protein) shortly after waking up to stabilize blood sugar
• Eat regular, balanced meals throughout the day. Think: protein + fiber-rich and colorful carbs + healthy fats
• Meet your vitamin C, magnesium, and vitamin B5 needs through food and supplements as needed
• Reduce sugar and processed foods in favor of whole foods
• Create a relaxing bedtime routine and go to bed around the same time each night
• Open the curtains when you wake up, or better yet, get outside first thing
• Spend time in nature – nature reduces stress and anxiety while recharging your resiliency
