Getting enough sleep
Getting adequate sleep and having a regular sleep-wake schedule may help reduce cortisol levels.
Fish oil is high in Omega 3 fatty acids which lower cortisol production due to mental stress, while the vitamin K2 content plays a role in replenishing hormone stores in the body.
Research suggests these herbs and natural supplements might lower stress, anxiety and/or cortisol levels: Ashwagandha. Rhodiola. Lemon balm.
Remember magnesium will help lower cortisol, if you do not have adequate levels of magnesium your body cannot relax and remove excess cortisol. Start by taking some at diner and before bed.
The level of cortisol in your blood, urine and saliva normally peaks in the early morning and declines throughout the day, reaching its lowest level around midnight. This pattern can change if you work a night shift and sleep at different times of the day.
Various factors can cause high cortisol levels. But the biggest culprits on the list are sleep insufficiency, chronic stress, circadian misalignment, high-intensity exercise or overtraining and certain medical conditions like Cushing's disease.
Index Foods
It is recommended to consume foods such as eggs, meat, poultry, fish, and vegetables to lower cortisol levels. High-glycemic-index foods containing large amounts of sugar or starch are poor choices for reducing this hormone level, and may even increase the level of cortisol in the blood.
As the body's primary stress hormone, cortisol surges when we perceive danger, and causes all the symptoms we associate with “fight or flight”—increased blood pressure and heart rate, muscle tension, and the digestive system slamming to a halt, resulting in nausea, vomiting, and diarrhea.
For humans, cortisol begins to increase immediately after fasting commenced (Fig. 1C) [78]. Five-day fasting increases cortisol levels and shifts the peak from the morning to the afternoon [79]. Other fasting experiments for 2.5 to 6 days dramatically elevates plasma cortisol levels [80–82].
Maintaining a healthy diet of lean proteins, fresh vegetables and fruits is an excellent way to reduce cortisol. These are foods that help the body sustain exercise and recover from workouts. Avoiding sugar and sweets also keeps the body from going through spikes in blood sugar, which can affect stress and mood.
After jolting you into wakefulness in the early morning, your body's release of cortisol surges for 30-45 minutes before gradually quieting down as the day wears on. Cortisol concentration then reaches its low point around midnight.
Caffeine also increases cortisol and epinephrine levels both at rest and during periods of stress (al'Absi and Lovallo, 2004). The cortisol response to stress varies across individuals (al'Absi et al., 1997), raising the question of variability in caffeine's effect on cortisol secretion.
Why is my cortisol high at night? An abnormally high level of cortisol at night may be caused by a short-term stressor (think fight or flight) or prolonged light exposure, and less screen time at night may be helpful in this situation.
So, what causes cortisol levels to rise in the morning? In anticipation of wake time, the circadian clock sets off a cascade of hormones that results in the release of cortisol. Past the early morning spike, your body's cortisol reserves gradually decline as the day goes on.
Vitamin D supplementation significantly reduced cortisol levels and cortisol:cortisone ratio but had a nonsignificant effect on cortisone.
Vitamin B12 is known to help your body produce more cortisol if you are deficient and help to control your cortisol if your levels are out of balance.
Medications to control excessive production of cortisol at the adrenal gland include ketoconazole, mitotane (Lysodren) and metyrapone (Metopirone). Mifepristone (Korlym, Mifeprex) is approved for people with Cushing syndrome who have type 2 diabetes or glucose intolerance.
Serum cortisol levels reduced with both Ashwagandha 250 mg/day (P < 0.05) and Ashwagandha 600 mg/day (P < 0.0001). Compared to the placebo group participants, the participants receiving Ashwagandha had significant improvement in sleep quality.
“Eating foods such as processed meats, high sugar foods, caffeine and alcohol, which provide little nutritional value, have been associated with more psychiatric symptoms and can increase cortisol levels—our primary hormone responsible for stress,” she said.
