Good health involves keeping all parts of the external body clean and healthy.
It is important for maintaining both physical and mental health.
In people with poor personal hygiene, the body provides an ideal environment for germs to grow, leaving it vulnerable to infection.
Personal hygiene is the practice of keeping all parts of the external body clean and healthy.
It is important because it protects you and others from getting or spreading infectious diseases
Good personal hygiene involves washing your hands with soap, bathing regularly, brushing your teeth, and keeping your hair and nails tidy.
Good personal hygiene involves washing your hands with soap, bathing regularly, brushing your teeth, and keeping your hair and nails tidy.
Personal hygiene deals with the continued cleanliness of one’s body, clothing, and overall being in order to preserve and maintain your health.
Every day we are exposed to millions of germs, viruses, bacteria, and more and it is each of our responsibilities to maintain proper personal and body hygiene so that we can limit our exposure, thus protecting our health and the health of others.
It is clear that practices like these are more important than ever.
Understanding the different ways to maintain good personal hygiene can make a far-reaching difference in our personal lives, the lives of our families of friends, and the lives of everyone around us who are currently experiencing the same hardships as we are.

Thank you ….Effects of Smoking on the Brain and Nervous System
Tobacco can be obtained by inhaling it or chewing it, but when inhaled, the mixture of nicotine with small tar particles travels to the lungs.
It is quickly absorbed there, then the nicotine is transferred to the bloodstream, and it soon reaches the brain within eight seconds after it is inhaled.
In the case of obtaining tobacco by chewing it; It takes three to five minutes for nicotine to reach the central nervous system.
Nicotine has a clear effect on both the central nervous system and the peripheral nervous system, depending on the person’s mood.
The dose of nicotine taken causes smoking to stimulate or relax.
Smoking may increase your risk of developing dementia and stroke, and it may also cause personality changes.
If you smoke, you may experience faster cognitive decline than non-smokers.
The longer you smoke, the higher your risk of greater loss of age-related brain volume.
Speaking of the rapid effect of nicotine, it can be explained as follows:
Increased blood pressure or hypertension.
Increased heart rate.
Increased breathing speed.
Constriction and contraction of the arteries.
Stimulation of the central nervous system.
Do you want to add a word or two?….
Smoking and Brain Aging
Although the effect of smoking on cognitive abilities is relatively little and needs more studies to be predicted correctly and completely, the effect of smoking actually exists, and this can be explained in some detail as follows:
Reduced cortical thickness of brain areas: Although the thickness of the cerebral cortex decreases with age as normal, smoking increases the possibility of this more, as it was found that the cerebral cortex of smokers is less thick than non-smokers.
This is because smoking destroys an important component of the brain, which is the gray matter, and we mention here that the cerebral cortex has a very important role in basic thinking skills such as learning and memory.
Nicotine in cigarettes causes addiction: The nicotine present in cigarettes causes addiction, and addiction to nicotine induces changes in the brain.
When smoking, the brain increases the number of receptors that nicotine naturally attaches to as a way of adapting to absorb the high doses that reach the brain.
Therefore, if a person stops receiving normal amounts of nicotine, they produce nicotine withdrawal symptoms, including confusion and the desire to smoke.
In fact, those who smoke temporarily show fewer withdrawal symptoms than others, and this helps them get rid of this habit more easily.
Your Comments….
Nicotine dependence: Regular and frequent smoking leads to what is known as nicotine dependence, which calls for an increase in the number of cigarettes used in order to be able to increase the percentage of nicotine that enters the body to achieve similar results.
It can be noted the smoker may suffer from a problem of psychological or physical dependence, or both, so smoking becomes a habit that is difficult to get rid of.
Psychological dependence: A smoker feels the desire to smoke when he is in a certain social environment or with friends.
Physical dependence: This appears after the smoker’s body depends on certain amounts of nicotine, and the body’s need for its presence after it has adapted to it.

Mental changes: The amount of changes that occur to the brain when smoking is not yet known, and it is not clear whether these changes are reversible after stopping smoking or not, but it is known that smoking is accompanied by dementia and a decrease in the level of perception or knowledge.
In fact, there are indications that smokers, on average, have a relatively poor cognition in the later stages of their lives, and that memory and flexible perception are less compared to non-smokers.
According to what was published in the National Center for Biotechnology Information (NCBI), smoking is associated with an increased risk of developing dementia.
It is believed that approximately 14% of Alzheimer’s cases around the world are attributed to smoking.
Smoking is also linked to brain atrophy, and a decrease in the volume of the cerebral cortex in some areas, as mentioned above.
