Air-Conditioning Use and Hygiene Care

The use of air conditioners plays an important role in ensuring temperature of a room.

However, living in an air-conditioned room also leads to some health problems due to the poor hygiene care of air conditioners.

Bacteria, fungi and so on can be found in the ductwork of air conditioning systems with poor hygiene.

There is constant temperature and humidity within the ductwork to allow them to grow, and over time, a lump of dust accumulated within the ductwork is a good nutrient source of bacteria and fungi.

In particular, mites inhabit the ductwork and grow with the fungus as a nutrient source.

In general, the main parts of the mechanical system in air conditioners are being managed, but the narrow ductworks that cannot be reached by the human hand are almost impossible to clean.

This is why during the long-term use, dust accumulates in the ductwork, and all kinds of pathogenic microorganisms inhabit and grow, entering the air conditioner and contaminating the room air.

Studies suggest that people working in an air-conditioned room have a relatively high incidence of irritation, weakness, sleepiness, discomfort, muscle pain, and cold as well as a significant reduction in work efficiency.

This is a phenomenon that occurs because the air conditioning system contaminates the indoor air.

Therefore, the ductwork should be well maintained when using an air conditioner.

To eliminate the source of contamination, the ductwork must be cleaned and disinfected by preventing the dispersion of spores so that fungal spores do not fly into the air in aerosol form.

Organic matter, dust and so on can reduce the effectiveness of the disinfectant, thus the waste of the ductwork must be removed thoroughly before disinfection.

The ductwork disinfection is mainly done when severely contaminated and no air conditioning system should be operated during disinfection.

A List of Foods that Should Not be taken in Hypertension

Some foods, which can cause rapid rise of blood pressure, should be taken with care or avoid when the blood pressure is too high.

Such foods are as follows.

1. Foods with high salinity

Salinity is a strong factor that has been proven to affect the rise of blood pressure.

Sodium holds hydration in the body. As a result, blood circulation increases, leading to higher blood pressure.

Among these foods are salted fish (herring, mackerel), cans (of fish, meat, and vegetables), sausages, smoked products, crisps, instant food, etc.

2. Foods with high sugar content

If a large amount of sugar suddenly enters the blood, it may result in hyperglycemia. This can activate the sympathetic nervous system and result in frequent veins, thereby increasing blood pressure.

In addition, large amounts of sugar destroy the elasticity of the blood vessels.

Among these foods are candies, sweet soda, fruit juice, honey, jam, etc.

3. Fat-rich caloric foods

A high intake of high-calorific foods results in a greater flow of blood to the digestive organs. To ensure this process, the heart begins to function more actively, which can result in a transient blood pressure rise.

In addition, saturated fat can lower the elasticity of blood vessels. Among these foods are fat-rich meat, fat, butter, etc.

Winter Underwear and Health

People often wear a lot of underwear, saying it can prevent them from the severe cold.

So, is it really good for health?

Wearing a lot of clothes prevents carbon dioxide and other harmful substances from escaping quickly out of the body, staying between the skin and clothing, interfering with the breathing activity of the skin as well.

The air between the clothes and the skin is also damp, so it prevents sweating properly as well as cooling off.

This makes your body sticky, your chest stuffy, and your mind restless. In addition, when the weather turns cold, heavy clothing often causes physical inactivity. Therefore, you can easily catch a cold, even in a small drop of temperature.

Thus, even in winter, you should make a habit of wearing a proper overcoat or padded clothes instead of heavy underwear.

Vascular System Diseases to Be Attentive

During the period of temperature change, blood cholesterol levels and body inflammatory levels rise.

Therefore, you should be cautious of vascular diseases in the morning when the whole body wakes up after having been in a relaxed state and sympathetic nerve gets strained.

You should be careful of angina and myocardial infarction.

In order for the heart to beat incessantly, it must be well-supplied with oxygen and nutrition.

There are large blood vessels that supply oxygen and nutrition to the heart, which are called coronary arteries.

Blocking of the coronary arteries can have irreversible effects on the heart.

Typical diseases caused by blockage of these vessels are angina and myocardial infarction.

It is called angina that blood is not supplied due to the accumulation of oil in the cardiovascular system, resulting in anemia in the heart muscle.

A typical symptom of angina is a severe pain and stress in the chest. A brief pause of chest pain lasts 2-5 minutes and then disappears.

Myocardial infarction refers to the sticky blood being tangled with intravascular waste to prevent blood vessels.

There is also arrhythmia among the diseases that need to be taken into account during the periods of temperature change.

Arrhythmia refers to the disease that heartbeat and pulse are abnormally fast, late, or irregular. Normal pulses range from 60-80 beats per minute. Even if you are not strained, you will develop symptoms that can cause a rapid beating of your heart or an intolerable pain in the chest. On the contrary, you might experience dizziness, dyspnea, weakness, fatigue, and so on as you lose strength.

Arrhythmia can cause intracardiac thrombosis, heart failure, stroke, and so on and, in severe cases, respiratory arrest.

Alcoholic and Soft Drinks Harmful to Liver

Alcoholic and soft drinks are harmful to liver.

Liver is an organ that degrades and detoxifies alcohol; therefore, excessive drinking can cause a burden on the liver, increasing the risk of developing liver diseases.

The appropriate amount of alcoholic drink is said to be about 20g of pure alcohol per day. One bottle of beer corresponds to 20g of pure alcohol.

In addition to alcohol, beverages supplemented with sugar, such as soft drinks, also imposes a burden on the liver, which is related to carbohydrates.

As sugar-rich soft drinks, coffee with sugar, and so on taste good, you should be careful not to drink too much of them.

Liver has a function of accumulating nutrients, with a limit to carbohydrate storage.

Therefore, excessive intake of carbohydrates turns into lipid and accumulate in the body.

This is the cause of fatty liver. It is recommended for you to drink proper alcoholic or soft drinks as a favorite drink.

Some Foods that Keep Brain Healthy

Brain is the main organ of the human central nervous system.

It is responsible for the function throughout the organism. Any abnormality in brain function immediately affects human vitality. Brain diseases bring about serious consequences. Therefore, it is important to pay attention to the proper nutritional intake to ensure that the brain gets enough vitamins, minerals and fat acid.

Foods that keep brain healthy are as follows.

1. Oil fish

Oil fish is a loyal "friend" of the brain. Fishes are rich in ω-3 fat acid. Fishes with the highest level of this substance are herring, mackerel, flatfish, salmon, etc.

In a sense, ω-3 fat acid is beneficial not only for the brain but also throughout the organism. That is, it not only builds and cleanses the vessel walls and normalizes blood pressure, but also prevents cardiovascular disease and improves metabolism.

The brain functions very well and efficiently thanks to the ω-3 fat acid.

2. Chocolate

It involves only the case of bitter chocolate with cocoa content of above 55%.

The higher the cocoa content, the more beneficial. Cacao fruit contains anthocyan that improves the function of the vessel walls and enhances blood entry into the brain. Thus, the brain becomes vigorous, functioning more effectively, and memory is improved.

3. Egg

Eggs contain many vitamin B complexes that are important for brain health. Eggs prevent senile dementia and improve the young’s abilities to remember and concentrate.

Yellow yolks contain choline, which is used to improve memory and treat atherosclerosis. Without choline, nerve tissue cells cannot function normally. Two eggs a day are enough to take daily quantities of choline.

4. Walnut

Walnuts contain melatonin, magnesium and ω-3 fat acid that are beneficial to the brain. These substances help to improve memory and other cognitive functions.

Walnuts, like other nuts and seeds, contain vitamin E that stimulates the brain. According to scientists, this vitamin can cope with free radicals, alleviate inflammatory processes in the body, and even prevent Alzheimer's disease.
