Physical or emotional tension triggers a series of physiological changes in the body. Almost all of the body's organs and functions react to stress: Excess adrenaline is secreted, heart rate and blood pressure increase, digestion can slow and cholesterol can rise. Cortisol, an adrenal hormone that regulates carbohydrate metabolism and blood pressure, is also released during stressful times.
Function of Cortisol
Cortisol is a steroid hormone that plays a role in many different body systems, such as the immune and circulatory systems, metabolic function, nervous system and bone health. Diseases such as Addison's and Cushing's disease can lead to high levels of cortisol. Physical and emotional stress increase the levels of cortisol in the blood. Chronic stress can lead to chronically elevated levels of cortisol, which can age brain cells and increase belly fat. Prolonged periods of stress can inhibit the body's ability to fight disease and reduce immune function.
Antianxiety Herbs
Hops, valerian, chamomile, catnip and kava kava can help calm the mind, body and nervous system. They may help reduce feelings of moderate anxiety, nervousness and stress. These herbs can have a sedative-like effect that may cause drowsiness and are used to help reduce insomnia. These herbs are often found in a variety of combinations in teas and pills that are used to help manage stress. These herbs should not be combined with other sedative medications.
Adaptogenic Herbs
The Ayurvedic herb ashwaganda is an adaptogenic herb that helps calm the nervous system, reduce feelings of stress and increase energy. Ashwaganda has been used for hundreds of years for its rejuvenating qualities. Holy basil, also called tulsi, can help reduce feelings of stress and lower cortisol levels. Ginseng, another adaptogenic herb, is recommended by the University of Maryland Medical Center for its ability to help the body cope with stress.
Considerations
A blood test can be performed to test the levels of cortisol in the blood. Although herbal remedies may help reduce symptoms of stress, which will help lower cortisol levels, always speak with a medical professional before starting a new herbal routine. Herbs may interact with prescription medications, and additional human clinical research is needed to confirm their efficacy.
