Oxytocin, a hypothalamic nonapeptide, is linked to increased levels of social interaction, well-being and anti-stress effects.
Stress causes the body to release the hormone cortisol, which is produced by the adrenal glands. Cortisol is important to blood pressure regulation and the normal functioning of several body systems including cardiovascular, circulatory, and male reproduction.
Serotonin: Dubbed the "feel-good hormone," serotonin plays a key role in staving off anxiety and depression. In fact, the main class of drugs used to treat these conditions — SSRIs (selective serotonin reuptake inhibitors) — increase serotonin levels in the brain.
Mood: Serotonin in your brain regulates your mood. It's often called your body's natural “feel good” chemical. When serotonin is at normal levels, you feel more focused, emotionally stable, happier and calmer.
Hormones of the HPA axis, such as Cortisol, or corticosterone (in rodents), ACTH, and CRF are usually increased in a state of fear and anxiety. They also appear to modulate the response to threatening events.
Average cortisol level was found to increase approximately 9 times in stressful periods compared with that in relaxed periods. STAI, which shows state anxiety, showed an increase supporting this increase.
The Let-Down Effect occurs when the body produces an immune response (i.e., we get sick or experience some type of headache or flare-up) just after a stressful event has subsided. For example, maybe you finished a project deadline, dealt with a family emergency, or endured some other adrenaline pumping event.
Deep breathing, relaxation strategies, physical activity, and social support can all help if you are feeling the effects of a fight-or-flight response.
So, if you find that your body is constantly reacting to everyday stress with the fight-or-flight response, it should be a warning sign that your sympathetic and parasympathetic systems aren't working together in harmony.
Causes of chronic fight-or-flight mode
The most common example of this is post-traumatic stress disorder, or PTSD. It can also come from long periods of overwork and sleep deprivation that have essentially trained your brain to be agitated all the time, even though your health is being sacrificed.
A deep sigh is your body-brain's natural way to release tension and reset your nervous system. Simply breathe in fully, then breathe out fully, longer on the exhale. Studieshave shown that a deep sigh returns the autonomic nervous system from an over-activated sympathetic state to a more balanced parasympathetic state.
Stress that's left unchecked can contribute to many health problems, such as high blood pressure, heart disease, obesity and diabetes.
When the stress response is turned on, your body may release substances like adrenaline and cortisol. Your organs are programmed to respond in certain ways to situations that are viewed as challenging or threatening. The stress response can work against you.
Runny noses, coughing, inflammation, and experiencing flu-like symptoms are indications that the body is working to expel pathogens. In both instances, we can feel sick after a stressor has passed due to how the body's immune system copes when the body is under stress.
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.
Common symptoms of stress in women include: Physical. Headaches, difficulty sleeping, tiredness, pain (most commonly in the back and neck), overeating/under eating, skin problems, drug and alcohol misuse, lack of energy, upset stomach, less interest in sex/other things you used to enjoy.
If chronic stress has led to overwork, you can usually recover from it within a few weeks. If chronic stress has led to burnout, your body is exhausted. With exhaustion, recovery usually takes six months, a year or even longer. There can be a lot of variation in that.
The most common areas we tend to hold stress are in the neck, shoulders, hips, hands and feet. Planning one of your stretch sessions around these areas can help calm your mind and calm your body. When we experience stressful situations whether in a moment or over time, we tend to feel tension in the neck.
If the stressful event continues to persist, the body will enter the exhaustion stage. Symptoms of this stage include burnout, fatigue, depression, anxiety, and reduced stress tolerance. As the stressful event persists, the body's immune system will continue to weaken.
You may remember your heart racing, palms sweating, shoulders tensing up. These reactions are part of the body's natural stress response. When the brain perceives a threat, it triggers a release of chemicals that prepare the body for the challenge.
Magnesium, B vitamins, ashwagandha, omega-3 fatty acids, and GABA are some of the most effective supplements for reducing stress and promoting nervous system health. As always, it's important to talk to your doctor before taking any new supplements.
Your exhale should be long and slow. This is key to stimulating the vagus nerve and reaching a state of relaxation. The vagus nerve is connected to your vocal cords and the muscles at the back of your throat. Singing, humming, chanting and gargling can activate these muscles and stimulate your vagus nerve.
