What Is Cortisol And How To Lower It

Summary: Cortisol is necessary for regulating stress, but maintaining the right levels is crucial, as excess cortisol can be harmful. Here are some tips on how to lower your cortisol naturally through stress reduction techniques. These include a healthy diet, regular exercise, adequate sleep and enjoyable activities.

The reality of life is that everyone deals with stress at some point. You may experience brief moments of high stress like when you are running late for work or in the minutes before an important presentation. Or you may suffer from chronic stress due to a long-term illness or financial insecurity.

Thankfully, our bodies are designed to combat stress by producing cortisol, a hormone released by the adrenal glands. Cortisol is commonly known as the “stress hormone” and helps your body regulate how it responds to a threat or challenge. Too much of it, however, can be a bad thing.

Let’s look at what cortisol is and how to lower cortisol levels.

Understanding cortisol, the stress hormone

Cortisol is a steroid hormone that plays an important part in many functions of your body. Cortisol helps us manage stress by preparing our bodies for either fight or flight — the ability to confront a problem directly or run from it. Besides regulating your stress, cortisol also helps:

• Manage your blood pressure
• Reduce inflammation
• Regulate your body’s metabolism
• Control your blood sugar levels
• Influence your body’s sleep-wake rhythms

Your pituitary gland, a small gland at the base of your brain, and the hypothalamus, a region of your brain that controls the release of hormones, work together to regulate the levels of cortisol in your body.

Why it’s important to maintain healthy cortisol levels

Cortisol levels that are either too high or extremely low can be hazardous to your health. There are at-home tests you can get at your local pharmacy to check and monitor your cortisol levels.  Wearable technology for tracking these levels is also on the verge of being launched. It’s important to maintain balanced levels of cortisol for your overall well-being.

Elevated cortisol levels over a prolonged period of time can have negative effects on your physical and mental health. Symptoms of high cortisol can include:

• Bruising easily
• Muscle weakness
• Weight gain in your abdomen and face
• High blood pressure
• Purple stretch marks
• Type 2 diabetes
• Irritability, anxiety and depression

It can also cause Cushing’s syndrome, which is a rare pituitary disorder that occurs when the body produces too much cortisol.

On the other hand, insufficient cortisol levels can restrict your body’s ability to respond to stress. Symptoms of low cortisol include:

• Chronic fatigue
• Low blood pressure
• Weight loss

Low levels of cortisol can be due to Addison’s disease, a potentially life-threatening condition where your body’s adrenal glands don’t produce enough cortisol.

How to lower cortisol naturally

The most straightforward way to lower your cortisol naturally is to reduce the stress in your life, a task that may be challenging but is definitely within your control.

The good news is that many of the tips on how to lower cortisol levels naturally are easy to follow and implement. Consider implementing some of these techniques for how to lower cortisol levels into your daily routine:

Practice mindfulness and relaxation: Spending just 15 minutes a day practicing relaxation techniques like meditation, yoga, or breathing exercises can help reduce stress and lower cortisol levels. Deep breathing is known to activate the vagus nerve, dampening the fight or flight response and thus lowering cortisol.

A popular breathing exercise is the 4-7-8 breathing technique. All you need to do is find a comfortable place to sit, and if possible, close your eyes. Then:

1. Breathe in through your nose for four counts.
2. Hold your breath for seven counts.
3. Exhale through your mouth for eight counts.
4. Repeat the exercise until you feel comfortable and calm.

Other stress-busting techniques include journaling, listening to calming music, or taking a warm bath.

Exercise regularly: Physical activity like walking, Pilates, swimming, or even some easy stretches can do wonders in relieving stress. However, high-energy exercise may have the opposite effect and could raise your cortisol levels, especially in short bursts. So, stick with low- to moderate-intensity exercise such as brisk walking or gentle yoga to if you are looking to reduce cortisol.

Get a good night’s sleep: Sleep deprivation can lead to a vicious cycle of irregular cortisol levels in your body. Lack of restful sleep can cause a rise in cortisol levels, and too much cortisol can cause sleep deprivation. To ensure you get a good night’s sleep, do something that helps you relax before bed, such as reading a book, drinking chamomile tea or taking a warm bath.

Control your exposure to blue light before bedtime: Blue light from cellphones or tablet screens can impact both cortisol and melatonin levels. Exposure to blue light can trick your brain into thinking it’s morning, causing cortisol to rise. In addition, melatonin — the sleep hormone — can’t be produced in the presence of blue light. So, read a book instead of scrolling through social media while in bed.

Do something you enjoy: Participating in an activity or hobby you enjoy can help reduce your stress and lower your cortisol. Some possible activities include gardening, dancing and even cleaning, if it brings you joy.

It might seem like odd advice, but laugh or giggle as much as you can, as both spontaneous and ‘forced laughter’ can bring cortisol levels down. Besides improving your mood and energy, ‘laughter yoga’, a combination of exercise and playfulness, has been shown to reduce cortisol levels of regular practitioners.

Limit coffee, cigarettes and alcohol: The caffeine in coffee and nicotine in cigarettes are stimulants that can disrupt your sleep pattern and increase your cortisol levels. Alcohol can have the same effect. So, it’s wise to limit your use of coffee, cigarettes and alcohol, especially close to bedtime, so you can rest easy and maintain low cortisol levels.

Spend time with a pet: There’s a reason dogs are called “man’s best friend.” Studies show that interacting with a (well-behaved) dog can help reduce stress and anxiety and improve your overall mood. In fact, spending time with a friendly pup can even increase levels of the feel-good hormone, oxytocin. If you’re a cat person, spending time with your feline friend can have the same effect.

Eat a healthy diet: The food we put in our bodies can have a significant impact on our cortisol levels. One study found that foods containing dietary fiber and Omega-3 fatty acids, as well as those that are aged or fermented, can help to reduce stress and anxiety, thus lowering cortisol levels. So fill your body with nourishing food.

Dehydration can also temporarily increase cortisol, so make sure to drink enough water throughout the day to stay hydrated.
