Why does poor sleep lead to poor memory?

Memory has a great impact on people's lives, because memory is the basis of people's personal activities. Once memory declines or disappears, it will have a very adverse effect on the body. There are many factors that affect memory. Among them, memory decline caused by poor sleep quality is the most common. Let's take a look at why poor sleep leads to poor memory? I hope everyone can understand it.

The reasons for the obvious decline in memory are long-term lack of sleep, lack of exercise, facing the computer all day, lack of fresh air, excessive smoking and drinking, etc., which can all lead to memory loss. This is a physiological reason. Long-term excessive anxiety, depression, excessive psychological pressure, etc. can also cause memory loss, which is a psychological reason. This memory impairment is a functional disorder caused by excessive brain fatigue. There is no damage to the brain's tissue structure, so it is functional, temporary and reversible.

With the increasing popularity of computers, young people in their twenties and thirties are increasingly suffering from memory loss. The main reason is that they rely too much on computers, which in turn weakens their brain function. Certain diseases, such as neurasthenia, depression, cerebral arteriosclerosis, chronic sinusitis, etc. are common causes of memory loss. Neurasthenia patients often show memory loss. The root cause is that their attention is distracted and they cannot concentrate, which affects their memory ability. Sleep is also closely related to memory. Poor sleep can also affect memory function, and patients with neurasthenia often have sleep disorders. From this it can be seen that patients with neurasthenia suffer from poor concentration and sleep disorders, which lead to forgetfulness.

Smoking is harmful to the brain and may cause memory loss as smokers age. Studies have shown that smoking is one of the risk factors for dementia in the elderly. One important cause of dementia is obstructed blood flow to the brain, and smoking can lead to vascular stenosis and insufficient blood supply to the brain.
