Hand washing is very important. Through touch, we take in information and substances from the environment. This information can be both positive (food) and negative (pathogens, toxic substances).

Therefore, we must take special care with the hygiene of our hands. In this article, we explain why it’s so important to wash your hands and the best way to do it. Take note!

What do we use our hands for?

Thanks to our hands, we’re able to carry out different daily activities through which we can catch or transmit germs, such as:

  • Understanding the world around us
  • Recognizing the texture of an object
  • Caressing our loved ones
  • Holding a purse
  • Preparing food
  • Eating
  • Playing, etc

In this way, if we neglect our hygiene, we can be harming not only our health, but that of the people around us – even our loved ones.

Personal hygiene and health

Since humans are born, they come into contact with their environment. We begin to relate to elements that are totally foreign to us. Therefore, our immune systems begin to strengthen, which prepares us to face future aggressions.

However, it’s not always possible to come out of these confrontations unscathed. As a consequence, diseases caused by viruses and bacteria that manage to enter the body appear.

That’s why for centuries people have been looking for ways to avoid or reduce the unfavorable influence of the outside world on their health. After numerous failures, they found the answer, which lasts to this day, and it’s good hygiene.

Hand washing helps to eliminate impurities that adhere to the skin of the hands and make us sick. In addition, there are other types of hygiene that we must take into account:

  • Food hygiene, which guarantees the correct state of the products we consume;
  • Mental hygiene, which takes care of the perfect development and psychological functioning of the person and his or her community.

However, the hygiene that most interests us in this article is the one that depends on each of us individually: personal hygiene.

Surely you may be thinking, “But I’m clean! I shower every day!” However, this alone is not enough to talk about proper personal hygiene. In addition, we must take into account several aspects whose importance we often fail to recognize.

Elements of good personal hygiene

Dietary hygiene

Who knew? Yes, a balanced and healthy diet is the basis of good health. Thus, a healthy diet can help boost the immune system, which helps protect us from germs and external agents.

Also, keep in mind that the body needs enough carbohydrates, vitamins, minerals, protein, and fiber to perform its vital functions, even if you’re trying to lose weight. It’s also important to eat about six small meals a day:

  • Breakfast
  • A mid-morning snack
  • Lunch
  • A mid-afternoon snack
  • Lunch
  • A light dinner

Don’t forget to chew your food well; this is an essential rule. That way, you will crush what you consume well and also facilitate its digestion. It’s also advisable to drink plenty of water – at least eight glasses a day.

Air and ventilation hygiene

Make sure to avoid dust and smoke, as well as polluted air. These threeharmful elements can:

  • Cause allergies
  • Damage your respiratory system
  • Cause toxic substances to build up in your tissues

In fact, some studies show that air pollution could be responsible for about 800,000 premature deaths each year. This is why it’s important to maintain proper hygiene at home:

  • Use the vacuum cleaner to remove dust, pet hair, and dander, as well as dust mites that accumulate in corners and carpets.
  • Avoid excessive heat in the rooms and make sure they are always well-ventilated.
  • Finally, a very simple tip: always breathe through your nose, since the air is filtered and heated before reaching your lungs.
