Study Shows How Smoke Exposure Might Influence Sleep in Adults in the Early Stages of Life

Sleep disorder symptoms are a common issue, and medical experts continuously examine research to fill in knowledge gaps. With an estimated 50 – 70 million adults suffering from sleep disorders, more information must become available to help with prevention and treatments for those with insomnia or other sleep-related disorders.

One such study recently published in Scientific Reports suggests that prenatal exposure to nicotine and its by-products can produce long-term effects on sleep and stress response in some areas of the brain. Using an animal model, researchers were able to show how sleep in adults may be influenced by events that occurred in the early stages of life.


By exposing pregnant mice to nicotine and its by-products in the concentration of passive cigarette smoke, the researchers observed that their offspring, as adults, showed significant sleep issues. Most of these outcomes were found between the resting and the active phases, which corresponds to the morning awakening in humans.

Researchers also found an alteration of the expression of the glucocorticoid receptors (the stress hormones) in the hippocampus. This structure is the most sensitive to stress during brain development.

This study found two important points for sleep disorder analysis. First, exposure to nicotine and its by-products in the early stages of life can alter the expression and balance of corticosteroid receptors in the hippocampus. And second, glucocorticoid expression in the hippocampus is linked to sleep reduction.

Sleep problems are becoming a prevalent issue in the adult population, so it is vital to understand the root cause to address preventative measures. A healthy lifestyle balance can help those who suffer from insomnia or other sleep disorders.

This led her to revolutionize her own diet to help her get healthier and tackle her health problems. She began treating her illness by living a more balanced lifestyle through healthy food choices, exercise and other alternative medicine such as meditation. This total positive lifestyle change led her to earn a diploma in Nutritional Therapy from Health Sciences Academy in London, England. Today, Sarah enjoys helping others by teaching healthy lifestyle changes through her personal consultations and with her regular contributions to the Doctors Health Press. Also, passionate about following her dreams in life, Sarah moved to France and lived in Paris for over 5 years where she earned a certification in beadwork and embroidery from Lesage (an atelier owned by Chanel). She then went on to be a familiar face sitting front row and reporting from Paris Fashion Week. Sarah continues to practice some of the cultural ways of life she learned while in Europe.
