Humans can encounter negative consequences that decrease their bodies functions while they are practicing their life styles. Emotional reactivity and stress hormone reactivity, both of which are two of the basic roles that occur in the brain, have negative impacts in humans health. In the future, children might gain strong mental behaviors such as grooming and licking because they play inside the body. It might be true that these effects, which are stress and emotions, are mental results from humans lives that cannot be controlled; however, it should be recognized that there is a relationship between the brain and human body function. As had been noticed in McEwen's paper, humans bodies can be damaged by mental reactions and these consequences can be transmitted across generations. Stress is one ramification of the mental reactions that occur inside the brain. When people experience stress or unpleasant emotions, they start to care these emotions in unhealthy methods; as a result, these methods damage people's health. Even though this process happens inside the brain, people's responses to these feeling affect their health negatively. As McEwen …show more content…
Prenatal stress is claimed to be a factor in causing preterm birth, as well as full term birth with low birth weight. Childhood experiences in emotionally cold families increase likelihood of poor mental and physical health later in life. As McEwen illustrated, "Effects of early maternal care are transmitted across generations by the subsequent behavior of the female offspring as they become mothers, and methylation of DNA on key genes appears to play a role in this epigenetic transmission"(3). Because these emotions can affect gens, it can be transmitted to children. Therefore, other generations also can be at risk of many diseases because these emotions are existed in their parents'
