Do you suddenly bolt awake between 1 and 4 AM, energy coursing through your veins? This can be one of many low blood sugar symptoms followed by a cortisol spike. Why?
Sleeping through the night represents a long period without food when blood sugar can drop too low. This is bad news for the brain, which depends on glucose for energy. When blood sugar drops too low, the body sounds the alarm bells to protect the brain. In response, the adrenal glands release stress hormones, mainly cortisol. Cortisol raises blood sugar back to a safe level. Unfortunately, sleep deprivation causes your body to secrete more cortisol during the day, perhaps in an effort to stimulate alertness leading to a further imbalance.
Cortisol is a hormone produced by a complex network known as the hypothalamic pituitary adrenal (HPA) axis. It is an alertness-boosting hormone. Normally, cortisol production normally drops to its lowest point around midnight and peaks about an hour after you wake up, around 9am.
Researchers have found that when the HPA axis is overly active, it can disrupt your sleep cycles, causing fragmented sleep and insomnia.
So what leads to this cortisol disruption?
➡️ Poor diet and a blood sugar imbalances
➡️ Eating while stressed or skipping meals sporadically
➡️ Chronic prolonged stress
➡️ Exposure to artificial light all day
➡️ Little to no sunlight exposure
➡️ Staying up late, especially on electronics
➡️ Lack of movement
➡️ Poor detoxification & elimination leading to chronic inflammation
➡️ Prolonged infections & lowered immunity
By addressing some of these lifestyle changes, we can balance these systems and get some well deserved full night’s sleep!
