Stress can be an inescapable part of modern life. Whether it's work-related pressures, financial worries, or personal struggles, we all face stress at some point in our lives. However, while a certain level of stress can be motivating and even beneficial, chronic stress can take a toll on our mental and physical health. In this blog, we'll explore the impact of stress on our lives and offer practical strategies to help manage it.
Impacts of Stress on the Body
Stress is a common aspect of daily life, but chronic stress can have a significant impact on our health. Stress triggers the release of various hormones in the body, including cortisol, adrenaline, and noradrenaline. These hormones play a crucial role in the body's fight-or-flight response, which can be beneficial in certain situations - like being chased by a bear. However, when stress becomes chronic, it can lead to several negative health effects, including increased cortisol levels, hormone imbalances, and inflammation.
Cortisol is a hormone that the body releases in response to stress. It plays a vital role in regulating the body's metabolism, immune response, and blood sugar levels. However, chronic stress can cause cortisol levels to remain elevated, which can lead to several health problems. High cortisol levels have been linked to weight gain, insomnia, depression, anxiety, and increased blood pressure.
Effects of Stress on Blood Pressure
Stress can have both short-term and long-term effects on blood pressure. When you experience stress, your body responds by releasing hormones that increase your heart rate and constrict your blood vessels, which can cause a temporary increase in blood pressure. In the short term, this increase in blood pressure is a normal and healthy response to stress, as it helps your body prepare for action.
However, if stress becomes chronic, meaning you experience it frequently or for long periods of time, the sustained increase in blood pressure can have negative effects on your health. Chronic stress can lead to various health problems, including high blood pressure (hypertension), which increases your risk of heart disease, stroke, and other complications. Additionally, stress can exacerbate existing hypertension, making it more difficult to manage with medication and lifestyle changes.
Chronic stress can also disrupt the balance of other hormones in the body, such as testosterone, estrogen, and progesterone. Hormonal imbalances can lead to a range of health problems, including mood swings, fatigue, and weight gain.
In addition to hormonal imbalances, chronic stress can also cause inflammation in the body. Inflammation is the body's response to injury, infection, or stress. However, when inflammation becomes chronic, it can damage tissues and organs, leading to several health problems, including heart disease, diabetes, and autoimmune disorders.
Effects of Stress on Blood Glucose
Stress can affect blood glucose, sometimes called blood sugar, levels in several ways. As we’ve discussed, when you are stressed, your body releases stress hormones such as cortisol and adrenaline, which can cause your liver to release glucose into your bloodstream. This is part of the body's natural fight or flight response to stress, which helps to provide energy to your muscles.
However, if you are experiencing chronic stress, this can lead to sustained increases in blood glucose levels, which can be harmful to your health. Over time, this can increase your risk of developing Type-2 diabetes, especially if you are already at risk due to other factors such as obesity or family history.
In addition to increasing blood glucose levels, stress can also make it more difficult for your body to use insulin effectively, which can further contribute to high blood glucose levels. Insulin is a hormone that is made and secreted by the pancreas, a gland located behind the stomach. The pancreas contains specialized cells called beta cells that produce insulin and release it into the bloodstream in response to rising blood glucose levels.
Once insulin is released into the bloodstream, it travels to various tissues and organs throughout the body, where it helps to regulate the uptake, use, and storage of glucose. Insulin acts as a key that unlocks the doors of cells, allowing glucose to enter and be used for energy. However, if this chain is thrown out of balance, it can lead to a cycle where stress worsens blood glucose control, which in turn increases stress levels.
Managing Stress for Better Health
So now that we know some of the ways stress can negatively impact the body, let talk about what can be done to manage stress. It's important to find healthy ways to manage and cope with stress in order to maintain optimal health. Things that can be helpful in managing stress can include regular exercise, mindfulness and relaxation techniques, and seeking support from friends, family, or a mental health professional if needed. These are some additional ways to help manage stress and feel better:
Exercise regularly: Regular exercise can help reduce stress by releasing endorphins, which are feel-good hormones that promote relaxation and improve mood.
Practice mindfulness: Mindfulness meditation, yoga, and deep breathing exercises can help reduce stress and promote relaxation.
Get enough sleep: Getting enough sleep is essential for reducing stress levels. Aim for seven to nine hours of sleep each night.
Eat a healthy diet: Eating a healthy diet rich in fruits, vegetables, whole grains, and lean proteins can help reduce stress and promote overall health.
Practice self-care: Taking time to do things you enjoy, such as reading, listening to music, or spending time with loved ones, can help reduce stress and promote relaxation.
Exercise & Stress Perception
Regular exercise can help to improve the body's response to chronic stress by reducing stress hormones, promoting relaxation, improving sleep, boosting mood, and enhancing immune function. As previously mentioned, endorphins play an important role in improving human perception of stress. Endorphins are natural chemicals produced by the body that act as neurotransmitters in the brain and nervous system and are released by the body during and after exercise. They are known for their pain-relieving and mood-boosting effects and are often referred to as the body's "feel-good" chemicals.
Endorphins are made in several areas of the body, including the pituitary gland, the hypothalamus, and the adrenal glands. When endorphins are released into the bloodstream, they bind to special receptors in the brain and nervous system called opioid receptors. This activates a cascade of events that can lead to feelings of euphoria, reduced pain perception, and a general sense of well-being.
Endorphins are stored in several areas of the body, including the pituitary gland, the hypothalamus, and the adrenal glands. They are also found in various tissues throughout the body, including the spinal cord and gastrointestinal tract.
Exercise is one of the most effective ways to stimulate the release of endorphins in the body. This is why many people report feeling a "runner's high" or other sense of euphoria after a challenging workout. But, generally speaking, any type of exercise that raises the heart rate and gets the blood flowing can help to stimulate the release of endorphins. Some types of exercise that have been shown to be particularly effective at releasing endorphins are:
Aerobic exercise: Aerobic exercise, also known as cardio, increases heart rate and blood flow, which can help to reduce tension and relax the body. This increased blood flow can also help to clear the mind and improve cognitive function, allowing us to better manage stress and think more clearly.
In addition, regular aerobic exercise has been shown to reduce overall levels of anxiety and depression over time. This may be due in part to the fact that exercise promotes the growth of new brain cells and increases the production of neurotransmitters, such as serotonin, that regulate mood. Even a short burst of exercise, such as a brisk walk or jog, can help to boost mood and reduce stress in the moment.
High-intensity interval training (HIIT): HIIT (high-intensity interval training) has been shown to be an effective way to reduce stress because it promotes the release of endorphins, natural chemicals in the body that act as mood boosters and painkillers. The short, intense bursts of activity followed by periods of rest or recovery that characterize HIIT workouts can stimulate the release of endorphins, which can help to reduce feelings of stress and anxiety.
In addition, HIIT workouts that are performed in a group setting or with music can further boost mood and promote a sense of community and social support. This sense of connection and belonging can help to reduce feelings of isolation and loneliness, which can be a source of stress.
Finally, the sense of accomplishment that comes with completing a challenging HIIT workout can promote feelings of confidence and self-efficacy, which can be powerful tools for managing stress.
Resistance training: Activities like weightlifting, bodyweight exercises, and resistance bands, like other forms of exercise we've mentioned, can also stimulate endorphin release and can help reduce feelings of stress and anxiety. Some of the other ways that resistance training promotes a better sense of well-being is through:
Increasing sense of control: Resistance training can give people a sense of control over their bodies and their environment, which can be empowering and help reduce stress levels.
Improving sleep: Resistance training has been shown to improve sleep quality, which can help reduce stress and promote overall health and well-being.
Enhancing self-confidence: Resistance training can lead to physical improvements in strength and muscle tone, which can enhance self-confidence and promote a positive self-image.
Reducing muscle tension: Resistance training can help to reduce muscle tension, which is often a physical manifestation of stress.
Promoting mindfulness: Resistance training requires concentration and focus, which can promote mindfulness and help individuals stay present in the moment.
Yoga and stretching: Yoga and stretching are effective ways to reduce stress because they promote relaxation and release tension in the body. When we experience stress, our muscles tend to tighten up, leading to physical discomfort and pain. Stretching and yoga poses help to stretch and lengthen these muscles, promoting relaxation and reducing tension.
In addition, both yoga and often stretching incorporate deep breathing techniques, which have been shown to be effective in reducing stress and promoting relaxation. By focusing on the breath and slowing down the body, we can calm the mind and reduce feelings of anxiety and stress.
Other activities shown to reduce stress include laughter and socializing. Overall, any type of exercise that is challenging, enjoyable, and performed on a regular basis can help to reduce stress, improve mood and overall well-being.
