A new study conducted by the Harvard Medical School in Boston reveals the answers related to how stress can affect our brains. The researchers performed their research on participants aged 49 years on an average and those who weren’t diagnosed with dementia.

Stress affects the body heavily and affects mind and body when experienced on the regular basis. The person who is suffering from stress on a regular basis they might feel tired or feel more irritable and are unable to focus properly. Moreover, chronic stress interrupts appetite, sleep patterns, and libido. It also worsens our health conditions that include heart diseases, diabetes, gastrointestinal problems, and other similar problems.

The researchers found that the participants having increased blood cortisol levels had a very poor memory when compared to people with normal blood cortisol level. This is because the participants were grouped into high, middle, or low levels of cortisol. Essentially, these participants had impaired memory much before the general symptoms of memory loss were appeared. The researchers also found that these results persisted even after adjustment in the investigation on the part of relevant modifying factors including smoking habits, sex, age, and body mass index.

After the result, the researchers stressed that people need to find ways to reduce stress. It is very important. This can be done with the help of getting enough sleep, incorporating relaxation techniques, and engaging in moderate exercise.

However, the study still has certain limitations such as only blood cortisol were taken into consideration rather than any other factor. This factor may not be representative of their long-term exposure to this hormone. In addition, the study mainly comprised of participants from European descent that implies the results may not be for other populations.
