Anxiety and depression share a biological basis. Persistent states of anxiety or low mood like those experienced by people with clinical anxiety and mood disorders involve changes in neurotransmitter function. Low serotonin levels are thought to play a role in both, along with other brain chemicals such as dopamine and epinephrine.
While the biological underpinnings of these problems are similar, anxiety and depression are experienced differently. In this way, the two states might be considered two sides of the same coin. If you have symptom of fatigue constantly, loss of interest, easily angry, difficult in concentration, sexual dysfunction and suicidal thoughts, you may have different levels of depression or anxiety (https://www.verywellmind.com/am-i-anxious-4045683).
CBD may help users to relax and unwind. By interacting with numerous receptor sites associated with feel-good neurotransmitters, CBD can temporarily shift brain chemistry to support feelings of ease and contentment.
Early research suggests that CBD increases levels of anandamide in the body. Also knows as "bliss molecule", anandamide plays the role of an endocannabinoid neurotransmitter. The appealing name of this chemical accurately describes how it can influence the mood.
Research links low levels of anandamide to mood disorders and apprehension. Interestingly, CBD might help to raise these levels. Typically, higher levels of anandamide equate to a better mood and feelings of relaxation. The bliss molecule is even believed to contribute to the so-called "runner's high" — a state of euphoria felt after aerobic exercise.
