Bahaya Vape Terhadap Paru-Paru dan Kesan Buruknya

 

Ramai pengguna vape beranggapan bahawa vape lebih selamat daripada rokok. Walaupun vape tidak menghasilkan tar seperti rokok biasa, ia tetap membawa risiko yang serius kepada kesihatan paru-paru.

1. Keradangan dan Kerosakan Tisu Paru-Paru

Cecair vape mengandungi bahan seperti propylene glycol, glycerin, nikotin dan pelbagai bahan perisa. Apabila dipanaskan, bahan-bahan ini boleh menghasilkan sebatian kimia yang merengsakan saluran pernafasan. Pendedahan berulang kali boleh menyebabkan keradangan pada paru-paru dan merosakkan tisu paru-paru yang sihat.

2. Risiko Penyakit EVALI

Terdapat satu penyakit yang dikenali sebagai EVALI (E-cigarette or Vaping Product Use-Associated Lung Injury), iaitu kecederaan paru-paru yang berkaitan dengan penggunaan vape. Pesakit boleh mengalami batuk yang teruk, sesak nafas, sakit dada, demam, dan dalam kes tertentu memerlukan rawatan di unit rawatan rapi (ICU). Ada juga kes yang menyebabkan kematian.

3. Mengurangkan Keupayaan Paru-Paru

Paru-paru berfungsi menyerap oksigen dan menyingkirkan karbon dioksida. Penggunaan vape secara berpanjangan boleh mengurangkan kecekapan fungsi ini. Pengguna mungkin mudah penat, cepat tercungap-cungap ketika bersenam dan kurang daya tahan fizikal berbanding individu yang tidak merokok atau menggunakan vape.

4. Risiko Penyakit Paru-Paru Kronik

Keradangan yang berlaku secara berterusan boleh meningkatkan risiko penyakit paru-paru kronik seperti bronkitis kronik dan penyakit pulmonari obstruktif kronik (COPD). Penyakit ini boleh menyebabkan kesukaran bernafas sepanjang hayat dan memerlukan rawatan berterusan.

5. Melemahkan Sistem Pertahanan Paru-Paru

Paru-paru mempunyai mekanisme semula jadi untuk menapis habuk, bakteria dan virus. Bahan kimia dalam vape boleh merosakkan silia, iaitu bulu-bulu halus yang membantu membersihkan saluran pernafasan. Akibatnya, pengguna lebih mudah mendapat jangkitan paru-paru seperti pneumonia dan bronkitis.

6. Pendedahan kepada Logam Berat

Kajian mendapati wap vape boleh mengandungi logam berat seperti nikel, timah dan plumbum yang berasal daripada elemen pemanas peranti vape. Apabila dihidu dalam jangka masa panjang, bahan-bahan ini boleh terkumpul dalam tubuh dan meningkatkan risiko kerosakan paru-paru serta masalah kesihatan lain.

Kesan Buruk Jangka Panjang

Antara kesan yang mungkin berlaku ialah:

Batuk berpanjangan.

Sesak nafas.

Cepat letih ketika melakukan aktiviti fizikal.

Jangkitan paru-paru yang lebih kerap.

Fungsi paru-paru yang semakin merosot.

Risiko penyakit jantung yang meningkat akibat nikotin.

Ketagihan yang sukar dihentikan.

Walaupun vape sering dipasarkan sebagai alternatif kepada rokok, bukti saintifik menunjukkan bahawa paru-paru manusia tidak direka untuk menyedut bahan kimia yang dipanaskan setiap hari. Paru-paru yang sihat memerlukan udara bersih, bukan wap yang mengandungi nikotin, bahan perisa dan pelbagai sebatian kimia lain. Oleh itu, mengelakkan vape adalah langkah terbaik untuk menjaga kesihatan paru-paru dan kualiti hidup dalam jangka panjang.

THE PHYSICAL BASIS OF THE BEAUTY IN PEACOCK FEATHERS REVEALED

Nobody looking at the patterns in peacock feathers can avoid being amazed at their beauty. One of the latest pieces of research by scientists has revealed that there is an astonishing design at the basis of these patterns.

Chinese scientists have discovered a delicate mechanism of tiny hairs in peacock feathers filtering and reflecting different wavelengths of light. According to a study performed by Fudan University physicist Jian Zi and colleagues, published in the journal Proceedings of the National Academy of Sciences, the feathers' bright colors are produced not by pigments, but by tiny, two-dimensional crystal-like structures. (1)

Zi and his colleagues used powerful electron microscopes to reveal the basis of the colors in the feathers. They examined the barbules of the male green peacock (Pavo rnuticus), in other words the even smaller micro hairs that come off of barbs emerging from the central stem of the feather. Under the microscope, they encountered the lattice design in the black-and-white picture to the right. This consisted of rods made of melanin, a protein, bound together with keratin, another protein. The researchers observed that these two-dimensional structures, each with a width hundreds of times thinner than a human hair, were arranged one behind the other on the micro hairs. Using additional optical examinations and calculations, the scientists examined the spaces between the crystals and their effects. As a result, it was revealed that the dimensions and shapes of these spaces in the lattice led to light being reflected at slightly different angles and thus to a variation in color.

"The male peacock tail contains spectacular beauty because of the brilliant, iridescent, diversified, colorful eye patterns," said Zi, who continued, "when I watched the eye pattern against the sunshine, I was amazed by the stunning beauty of the feathers." (2) Zi stated that until their study, the exact physical mechanism producing the colors in peacock feathers had not been known, and that although the mechanisms they had revealed were simple, they were absolutely ingenious.

Obviously, there is a very specially regulated design in peacock feather patterns. The tiny lattices and spaces between them are of the greatest importance in this design. The adjustment between the spaces is particularly striking. Were these not so arranged as to reflect light at slightly different angles to one another, then this variation in color would not take place.

The greater part of the color in the peacock feather is based upon structural coloration. There is no pigment in those parts of the feather that exhibit structural coloration, and colors reminiscent of those on the surface of a soap bubble are able to emerge. The color of human hair comes from pigment, and no matter how much care a person may take of his or her hair, it is never as shiny and beautiful as a peacock feather.

It has also been stated that this intelligent design in the peacock can be a source of inspiration in industrial design. Andrew Parker, a zoologist and coloration expert at the University of Oxford, who interpreted Zi's findings says that discovering so-called photonic crystals in peacock feathers could allow scientists to adapt the structures for industrial and commercial applications. These crystals could be used to channel light in telecommunications equipment, or to create new tiny computer chips. (3)

It is clear that the peacock has marvelous patterns and a special design, and that thanks to the imitation of this mechanism, maybe in the near future, we shall see objects and accessories covered in the brightest of coatings. Yet how did such a gorgeous, intelligent and inspirational design first emerge? Could the peacock know that the colors in its feathers depended on crystals and the spaces between them? Could the feather have itself brought the feathers on its body into being and later have decided to add a coloring mechanism to them?
Could it then have arranged that mechanism in such a way as to produce those stunning designs? Of course, not.

For example, if we were to encounter marvelous patterns made out of colored stones as we walked beside the edge of a river, and if we also saw that there were eye-like designs arranged like a fan, then we would think that these had been laid out in a conscious manner, and not that they had appeared by chance. It would be evident that these patterns, reflecting an artistic perspective and addressing human aesthetic tastes, had been made by an artist. The same thing applies to peacock feathers. In the same way that pictures and designs reveal the existence of the artists who produced them, the patterns in the peacock feather reveal the existence of the Creator Who made them. There can be no doubt but that it is God Who brought together and arranged the crystal-like structures in the peacock feather and produced such marvelous patterns from them. God reveals His flawless creation in a verse from the Qur'an:

He is God - the Creator, the Maker, the Giver of Form. To Him belong the Most Beautiful Names. Everything in the heavens and Earth glorifies Him. He is the Almighty, the All-Wise. (Qur'an, 59:24)
