The Use Of Lasers In Medicine
What is a Laser?
Light amplification by stimulated emission of radiation is one of the most widely used technologies in medical science. Using this technology is cost-effective, without pain and complications. A laser is a high-energy excited light. Light amplification by stimulated emission of radiation is different from normal light. Laser can be created by special equipment. In this article, we introduce a number of laser applications in medicine .
The Use Of Lasers In Medicine
A laser is also a light. Laser has differences with ordinary light, which makes the laser’s efficiency extraordinary. The differences between laser and normal light are:
Ordinary light consists of visible and invisible light energy. Normal light consists of ultraviolet rays with the shortest wavelengths to infrared rays with the longest wavelengths. Laser consists of a type of light energy with a specific wavelength.
A laser is a monochromatic light. The accuracy and energy of laser is several thousand times higher than normal light.
The emission property of laser light is lower than normal light. When the laser is used in special devices, the laser passes its direct path exactly at a distance of several hundred meters. The radius of the radiation circle near the laser is equal to the radiation radius at several hundred meters of the laser. Because of this special feature, lasers are used in medicine.
Laser applications in medicine
Use of laser in surgery
Due to the unique features of laser, laser is used in the field of medicine to treat diseases and surgeries.
Today, lasers are used instead of knives in surgeries. The advantages of using laser in surgeries are:
Wound cutting : The advantage of laser surgery compared to traditional surgery without laser is cutting the wound by laser rays. In traditional surgery without laser, after cutting with a knife, the patient suffers pain, bleeding, and problems with dressing and post-operative care.
Anesthesia : General anesthesia is one of the concerns and limitations of surgery. In laser surgery, the problem is solved with local anesthesia of the patient.
Pain and bleeding : laser surgery has less pain and bleeding. Laser rays are painless when repairing damaged nerves. In laser surgery, capillaries and blood vessels are burned without bleeding.
Hospitalization of the patient : After the traditional surgery, the patient has to be hospitalized for 1-2 days due to pain, general anesthesia and bleeding. In the laser surgery method, the patient is immediately discharged and goes about his daily activities.
Duration of operation : The duration of laser operation is less than 1 hour. Traditional surgery takes longer due to anesthesia, wound incision, drainage and dressing.
Cost : The cost of traditional surgery is much higher than laser surgery due to the duration of surgery, hospitalization of the patient, multiple dressings and drugs. It should be noted that all insurances cover the cost of laser surgery.
Transmission of disease : due to open surgery without laser, the possibility of transmission of infectious and blood diseases is higher in traditional surgical method.
Use of laser for skin beauty
Another use of laser in medicine is skin rejuvenation and beauty. To rejuvenate the skin and solve skin problems, the use of laser is cheap, fast and without side effects. The application of laser for skin beauty is:
Removal of light and dark vascular moles
Removing various skin spots such as freckles and tattoos
Treatment and reduction of body hair growth
Removing skin wrinkles
Removal of skin warts, scars, stitches and burns
Removal of localized obesity (cellulite)
Lasers are also used in gum surgeries, cell repair and anti-inflammatory treatments in the field of dentistry. The use of laser reduces the pain and high cost of dental treatments. Laser applications in dentistry include:
Accurate diagnosis of tooth decay
Prevention of tooth decay
Eliminate tooth sensitivity
Use of laser in ophthalmology
Another advantage of laser is the treatment of eye diseases and problems. The application of laser in the field of ophthalmology is:
Treatment of glaucoma
Treatment of eye bleeding
Fix retinal detachment
Treatment of visual impairment
“Laser has many other applications in the field of treatment, such as treating hemorrhoids , treating hair cysts , treating fissures , etc. In this article, we have mentioned small parts of the application of this technology.

Why ADHD is Common These Days? Top Reasons
Attention deficit/hyperactivity disorder (ADHD) has become increasingly common in recent years, affecting individuals of all ages. This article aims to shed light on the reasons behind the rising prevalence of ADHD, exploring various factors that contribute to its occurrence in today’s society. Here are some of the reasons of why ADHD is common these days.
Improved Diagnostic Awareness:
One significant factor contributing to the apparent increase in ADHD cases is the improved diagnostic awareness and understanding of the disorder. In the past, ADHD was often misunderstood or misdiagnosed as simply a behavioral problem. However, increased education and awareness among healthcare professionals, teachers, and parents have led to earlier and more accurate diagnoses.
As a result, individuals who may have gone undiagnosed in previous years are now being identified and treated appropriately.
Reasons why ADHD is common these days also include genetic factors. Studies have shown that ADHD tends to run in families, indicating a strong genetic component. Certain genes involved in regulating dopamine, a neurotransmitter that plays a crucial role in attention and impulse control, have been linked to an increased risk of developing ADHD. However, no single gene has been identified as the sole cause of ADHD, suggesting that multiple genes and gene interactions contribute to its development.
Brain imaging studies have shown that the shape and function of the brains of people with ADHD are different. Specifically, there are differences in the regions responsible for attention, impulse control, and executive functions. These differences may affect the communication and coordination of neural networks involved in cognitive processes, leading to the symptoms observed in ADHD.
Neurotransmitters, such as dopamine and norepinephrine, play important roles in regulating attention, impulse control, and hyperactivity. Individuals with ADHD may have imbalances or dysregulation of these neurotransmitters, which can affect the brain’s ability to maintain focus, regulate impulses, and control behavior.
Evolving Environmental Factors:
Environmental factors in modern society can also contribute to the increased prevalence of ADHD. Some potential factors include:
The advent of smartphones, tablets, and other digital devices has brought about increased screen time and digital stimulation. Excessive screen time and overexposure to stimulating content may affect attention span and contribute to attention difficulties associated with ADHD.
Changes in Lifestyle and Diet:
Sedentary lifestyles, and poor nutrition, are one of the top reasons why ADHD is common these days. The consumption of processed foods high in artificial additives has become more prevalent in recent decades. These factors have been suggested as potential contributors to ADHD symptoms, although more research is needed to establish definitive links.
Exposure to certain environmental toxins, such as lead, pesticides, and air pollutants, has been associated with an increased risk of neurodevelopmental disorders, including ADHD. Industrialization and urbanization have led to higher levels of exposure to these toxins in some areas.
Societal and Educational Demands also contribute to why ADHD is common these days:
Modern society places high demands on individuals, including children, in terms of academic performance, multitasking, and meeting strict deadlines. The increased pressure to excel academically and the proliferation of structured activities may contribute to heightened stress levels and difficulties in maintaining attention and focus, potentially leading to the manifestation of ADHD symptoms.
While the exact reasons for the increasing prevalence of ADHD are multifaceted and not fully understood, several factors contribute to its rise. Improved diagnostic awareness, broadening diagnostic criteria, evolving environmental factors, and societal demands all play a role. It is crucial to continue research efforts to better understand and address the factors influencing ADHD prevalence to support affected individuals effectively.

Skin Pigmentation and Acne on the Face
Skin Pigmentation and Acne on the Face Top Reasons
Pigmentation and acne are common problems that make people feel bad about themselves and hurt their general health. In this article, we will explore the causes behind these conditions and discuss effective remedies for achieving healthier, clearer skin. Skin pigmentation and acne on the face top reasons include many. However, we need to understand what really is skin pigmentation.
Skin pigmentation is the quantity of melanin in the skin, which gives it its color. Melanin is a pigment produced by specialized cells called melanocytes. While pigmentation is influenced by genetics, various internal and external factors can lead to its alteration. Skin pigmentation and acne on the face top reasons are:
Excessive exposure to ultraviolet (UV) radiation from the sun stimulates melanocytes, leading to an overproduction of melanin. This can be skin pigmentation and acne on the face top reasons.
Fluctuations in hormone levels, particularly during pregnancy or while taking hormonal contraceptives, can trigger melasma. This condition causes dark patches on the face and is often referred to as the “mask of pregnancy.”
Post-Inflammatory Hyperpigmentation (PIH):
Inflammatory conditions like acne, eczema, or skin injuries can cause PIH, resulting in dark spots or patches. PIH occurs when melanocytes produce excess melanin in response to inflammation or trauma.
Acne on the Face:
Acne is a common skin disease that is marked by pimples, blackheads, whiteheads, and cysts or nodules in more severe cases. It happens when oil, dead skin cells, and germs get stuck in the hair follicles. Acne can be caused by more than one thing.
Hormonal fluctuations are one of the skin pigmentation and acne on the face top reasons, especially during puberty, menstruation, or hormonal disorders, and can increase sebum productionAcne caused by the clogging of pores by excess sebum and dead skin cells.
Propionibacterium acnes, a bacterium naturally present on the skin, can multiply in clogged pores, leading to inflammation and acne. Genes play a part in whether or not someone gets acne. If your parents had acne, you may be more likely to get it as well.
Diet and Lifestyle:
Consuming a diet high in processed foods, dairy products, or refined sugars may worsen acne. Additionally, factors like stress, inadequate sleep, and smoking can aggravate acne symptoms.
Remedies for Skin Pigmentation and Acne on the Face:
Apply sunscreen daily, wear protective clothing, and limit sun exposure to prevent further pigmentation.
Over-the-counter creams, serums, or prescription medications containing ingredients like hydroquinone, retinoids, or azelaic acid can help fade pigmentation and treat acne.
Dermatological procedures such as chemical peels, laser therapy, microdermabrasion, or photo facials can effectively reduce pigmentation and improve acne.
Adopt a balanced diet, practice good hygiene, manage stress, and maintain a regular skincare routine tailored to your skin type.
Understanding the causes of skin pigmentation and acne on the face empowers individuals to take appropriate measures for prevention and treatment. By implementing a comprehensive approach that includes sun protection, topical treatments, professional interventions, and lifestyle modifications, one can achieve clearer, healthier skin.

10. Tips for being happy: forget the result
First, clinging to things getting done a certain way, or waiting for the perfect moment to be happy can keep you from finding happiness.
You may feel that current circumstances must dictate your level of happiness.
You may think that you have to force fate and reach the final goal to deserve to be happy. But the problem is that you will never get to happiness if you wait to be happy.
Happiness is not a goal, but the path to the result. Stress and disappointment are based on expectations. Then look at how many of them are really realistic. Ask yourself why you keep clinging to the ones that aren’t.
