The unconscious functions of the brain, such as blood pressure and heart rate, are also positively affected. This stimulation of the brain eventually reduces stress and boosts energy and relaxation.

Aromatherapy essential oils release chemicals like endorphins and serotonin in the body, promoting pleasure and happiness. This consequently calms and relaxes the mind.

Nervous System & Essential Oils

Essential oils help balance the body’s communication channel— The nervous system. This system helps us sense our environment and generate the related response. It is responsible for coordinating all our actions and sensory information. It also helps recognise environmental changes that impact the body. Pure, undiluted essential oils used in aromatherapy support a healthy nervous system. The system’s functions can benefit immensely by using aromatherapy products with essential oils. The central nervous system is responsible for controlling and coordinating all the activities you do. This includes thinking, breathing, feeling and walking. The system comprises the brain, spinal cord and the network of nerves in the body. These nerves carry messages from the brain to different parts of the body and vice versa, making it easier for the brain to interpret and take appropriate action.

Essential Oils & the Cardiovascular system

Essential oils have shown that ingesting aromatic compounds through aromatherapy has incredible heart health benefits.

The cardiovascular System, also known as the circulatory system or the blood-vascular system, is composed of the heart, veins, arteries, and capillaries. It is responsible for circulating blood, which delivers nutrients and oxygen to the tissues through the bloodstream.

The cardiovascular system maintains homeostasis, which is dependent on the controlled and continuous flow of blood through the capillaries, which reach every tissue and cell in the human body. Many control mechanisms integrate and regulate all functions and components of the system to supply blood to all body areas as required.
