We usually wake up at six in the morning to start our school or work routine; therefore, after 10:00 a.m. we want to take one or several naps. This situation is quite common and may not have anything special to the naked eye, but when the desire and sensation of sleep last for hours, even days, it could be a warning signal.
According to a study published in the scientific journal JAMA Neurology, in which more than 2,900 people were studied, feeling excessively sleepy during the day doubled the chances of developing Alzheimer's.
In the study conducted by experts at the Mayo Clinic in Minnesota, United States, it is claimed that excessive daytime sleepiness is associated with an increase in the accumulation of amyloids. (Amyloid: protein that Alzheimer's disease accumulates in the brain and strangle to nerve cells).
This means that people with drowsiness or excessive sleep during the day are more vulnerable to the pathological changes associated with Alzheimer's.
When you sleep, your brain eliminates the unnecessary deposits of amyloids for the proper functioning of memory, but when you do not have a good night's sleep the amyloids accumulate and cause irreversible damage.
Participants who reported daytime sleepiness had more amyloid deposits compared to those who were not very sleepy during the day.
Maintaining a stable sleep cycle is paramount, otherwise you will attract a series of problems to your health. You will accumulate amyloids in the brain, you will mess up the production of neurotransmitters such as serotonin and dopamine and your mood will not be the best. Therefore, the ideal is to sleep seven to eight hours a day.
