Managing Cortisol Levels: The Key to Reducing Nighttime Wake Ups

Do you find yourself waking up at 3 a.m. and can’t fall back asleep? Cortisol may be to blame. Find out how regulating your stress hormones may bring sleep back to your nights.

What Is Cortisol and Why It Matters

Sleep is the body’s most powerful form of restoration but for many, staying asleep can be just as challenging as falling asleep. One of the hidden culprits behind nighttime waking can be cortisol, the body’s primary stress hormone. The good news is that understanding how cortisol works and learning how to regulate it can help you finally get the sleep you need.

Cortisol is produced by the adrenal glands and plays an essential role in keeping your body balanced. It regulates blood pressure, supports metabolism, and helps you respond to stress.

In a healthy rhythm, cortisol levels peak in the early morning in order to help you wake up. It begins to gradually decline throughout the day, reaching it's lowest point at night in order to help you sleep. However, when chronic stress, poor diet, or hormonal changes disrupt this rhythm, cortisol can spike at night, triggering wakefullness when you want nothing more than to be sleeping!

How High Cortisol Affects Nighttime Sleep

When cortisol levels remain high in the evening, you may experience:

• Difficulty falling asleep

• Frequent waking in the night

• Nightime/early morning waking (around 2–4 a.m.)

• Racing thoughts or anxiety at bedtime

• Daytime fatigue despite a full night in bed

This pattern is especially common during perimenopause and menopause due to fluctuations in estrogen and progesterone that can influence cortisol balance.

Strategies to Support Healthy Cortisol Levels

1. Create a Calm Evening Routine

This helps signal to your body that it’s time to unwind. Dim the lights, reduce bright screen exposure, and replace stimulating activities with calming rituals such as reading, light stretching, or gentle breathing exercises. If you've got kids at home it can be a great opportunity to create an evening wind down routine for the whole family.

2. Practice Stress Management Daily

Cortisol responds to both physical and emotional stress. Incorporate short moments of mindfulness or relaxation throughout your day. Don't underestimated the benefits of five minutes of slow, diaphragmatic breathing or a midday walk outdoors!

3. Balance Blood Sugar

Sharp drops in blood sugar can trigger cortisol release at night. Try eating balanced meals with protein, healthy fats, and complex carbohydrates throughout the day. If you tend to wake up hungry at night, a small protein rich snack before bed may help.

If you're like me and find great joy in nighttime snacking, reach for food rich in magnesium, tryptophan, and healthy fats such as almonds, a banana, or cottage cheese. These may not bring you the same dopamine rush as a sugary sweet but they can calm the body and provide slow burning energy without causing blood sugar spikes or other sleep disruptions like sugary snacks can.

4. Reduce Stimulants

Caffeine and nicotine elevate cortisol and can delay its natural evening decline. Try to limit caffeine after 2 p.m. and consider switching to herbal teas such as chamomile or rooibos in the afternoon and evening.

5. Exercise - But Time It Right

I cannot stress how beneficial exercise is to our physical and mental health. Moderate physical activity reduces cortisol over time, but intense workouts close to bedtime can do the opposite. Aim for morning or early afternoon exercise for optimal hormone balance. If you can get for a walk outside within one hour of waking up, even better!

6. Support Hormonal Balance

For individuals in perimenopause or menopause, shifting hormone levels can heighten cortisol reactivity. Working with a professional who understands this relationship can help tailor nutrition and lifestyle to support balance. This can be done without the use of hormonal therapy.

7. Prioritize Consistent Sleep Patterns

Going to bed and waking up at the same time each day reinforces the body’s natural circadian rhythm and helps cortisol follow a daily pattern.

The Bottom Line

Managing cortisol isn’t about eliminating stress, instead it’s about teaching your body how to manage and recover from it. By supporting healthy cortisol rhythms through daily habits, you can reduce nighttime wakings, improve your energy levels, and regain a sense of control over your sleep!
