Does Stress Raise Blood Sugar? Exploring the Link and Management Techniques


Stress and elevated blood sugar levels are two conditions often associated with each other. Stress is a biological and psychological response to external stimuli that requires action or adaptation, and it can affect every aspect of our health and wellbeing, including blood sugar levels. Stress-induced blood sugar spikes can be especially problematic for people with diabetes. This article explores the connection between stress and high blood sugar levels, examines the underlying science, and offers some stress management techniques to keep blood sugar levels in check.

The Link between Stress and High Blood Sugar Levels

Stress can affect blood sugar levels in different ways, depending on the specific biological and psychological response triggered by the stressor. The stress response involves several hormones, including adrenaline, cortisol, and glucagon, which prepare the body to face a threat. These hormones raise blood sugar levels by stimulating the breakdown of glycogen stored in the liver and muscles. This allows the body to release glucose into the bloodstream as energy fuel for the muscles and the brain. However, if the stressor persists or is chronic, this process can become overactive, leading to chronically elevated blood sugar levels.

The Science behind the Stress-Blood Sugar Connection

Research has found a clear link between stress and elevated blood sugar levels, even in people without diabetes. A study published in the Journal of Clinical Endocrinology and Metabolism found that acute mental stress, such as public speaking or solving math problems, can raise blood sugar levels by up to 15% in healthy adults. This effect was more pronounced in people with impaired glucose metabolism, such as prediabetes or insulin resistance.

One mechanism behind the stress-blood sugar connection is the activation of the sympathetic nervous system and the release of adrenaline and noradrenaline. These hormones stimulate the breakdown of glycogen and the release of glucose into the bloodstream. Additionally, chronic stress can lead to increased insulin resistance, meaning that the body’s response to insulin is impaired, and blood sugar levels remain elevated.

Stress Management Techniques to Lower Blood Sugar Levels

Managing stress is essential for maintaining healthy blood sugar levels, particularly in people with diabetes. Here are some stress management techniques that can help:

Meditation: Meditation is a practice that involves focusing one’s attention on a particular object, thought, or activity to achieve mental clarity and relaxation. Several studies have found that meditation can help lower blood sugar levels, reduce stress, and improve overall wellbeing in people with diabetes.

Deep Breathing: Deep breathing exercises, such as diaphragmatic breathing or belly breathing, can help reduce stress levels and promote relaxation. By taking slow, deep breaths, you can activate the parasympathetic nervous system, which slows down many bodily functions, including heart rate and breathing, and reduces stress hormones’ release.

Exercise: Regular exercise is an effective stress-busting tool that can also lower blood sugar levels and improve insulin sensitivity. Exercise triggers the release of endorphins, the body’s natural painkillers and feel-good hormones, and reduces cortisol and adrenaline levels.

Relaxation techniques: Other relaxation techniques that may help manage stress and blood sugar levels include progressive muscle relaxation, guided imagery, aromatherapy, biofeedback, and yoga.

How Stress Can Impact Diabetes Management

Managing stress is vital for people with diabetes, as it can have a profound impact on their blood sugar levels and overall health. Chronic and unmanaged stress can affect diabetes management in several ways, including:

Difficulties in managing blood sugar levels: Stress can make it harder for people with diabetes to balance their blood sugar levels, making it more difficult to avoid highs and lows. This is particularly important for people with type 1 diabetes, who have to take insulin or other medications to manage their blood sugar levels.

Increased risk of complications: Chronic stress has been associated with a higher risk of developing diabetes complications, including eye problems, nerve damage, kidney disease, and heart disease. Stress can also exacerbate existing complications by increasing inflammation, impairing wound healing, and interfering with immune function.

The Role of Diet and Exercise in Reducing Stress-Induced Blood Sugar Spikes

Diet and exercise can play a crucial role in managing stress and lowering blood sugar levels. Here are some tips to help reduce stress-induced blood sugar spikes:

Eat a balanced diet: A nutritious diet rich in fiber, complex carbohydrates, lean protein, healthy fats, and antioxidants can help stabilize blood sugar levels and promote overall health and wellbeing. Avoid sugary and processed foods and opt for whole, unprocessed foods that provide sustained energy and keep hunger at bay.

Exercise regularly: Regular exercise can help reduce stress levels, improve insulin sensitivity, and decrease blood sugar levels. Aim for at least 30 minutes of moderate-intensity exercise most days of the week, such as brisk walking, cycling, or swimming.

Practice mindful eating: Mindful eating involves paying attention to your senses, emotions, and hunger and fullness signals while eating. This practice can reduce stress-related emotional eating and promote healthy eating habits.


Stress and high blood sugar levels are interconnected conditions that can have a significant impact on our physical and emotional health. Managing stress through relaxation techniques, exercise, and a balanced diet is essential for maintaining healthy blood sugar levels, especially in people with diabetes. By taking proactive steps to manage stress, you can reduce the risk of long-term complications and improve your overall quality of life.
