Not much sleep, less likely to get dementia

Attention, Sleepyhead! Too much sleep may harm your health.

Spanish researchers found that older people who sleep more than nine hours a day, have a higher risk of developing dementia.

Dementia is a disease of the nervous system which is characterized by a deterioration of mental capacity and impaired concentration. Dementia is a disease that can occur during old age.

The study involved 3, 300 adults who were subjected to periodic surveys over three years. The results showed that those who sleep ten or more hours per day, including during the day, run the risk of advanced dementia and the risk is increased twofold.

Conclusions have been made taken into account other factors such as age, education, bad habits, smoking and consumption of alcohol.

Threatened with dementia are smokers. Smoking increases the average age of the possibility of developing dementia by 75%. However reading, writing and card games can slow the progress of dementia.
