Now, you don’t often hear about cats getting depressed. In fact, most people don’t even know if depression is possible in animals.
A typical morning for cats usually involves purring, meowing, and stretching alongside family members. Then they’ll go to their favorite place to settle down in, and you continue with your day.
While we become comfortable with our cat’s daily routine, do we actually know our feline pets? What if your cat is depressed? Could you understand why? How can you help your cat overcome winter blues?
Cats are extremely sensitive to changes in light, more than humans. If there’s less light, a decrease in brain chemicals, including serotonin, can occur. When the weather changes to rain or snow, it’s not unusual for cats to feel the shift in sunlight.
Your cat, whether indoor or outdoor, may become depressed during the winter months. The lack of sunlight, less physical activity, and more time alone can contribute to feelings of restlessness or seasonal affective disorder (SAD).
What causes SAD?
SAD in felines occurs similar to humans, and it’s highly influenced by the amount of sunlight they’re exposed to daily.
If your cat has SAD, you may notice them behaving gloomy and moving slower than usual during the winter. However, when April and May roll around, they have more energy and appear happier.
The lack of sunlight is a serious problem as it reduces melatonin production, which results in depression, lethargicness, and anxiety. It also creates low levels of serotonin which acts as a neurotransmitter. With low serotonin, your cat may show signs of aggression, mood swings, and depression.
Achieving chemical balance is not easy, especially since serotonin cannot be given in a shot or pill. While your vet may prescribe a serotonin reuptake inhibitor (SRI), it comes with its side effects. A natural and non-invasive treatment option is light therapy, which adds natural sunlight into your cat’s environment to restore their chemical balance.
Using light therapy to treat SAD
You’ll often heart veterinarians recommend light therapy as a treatment for SAD. Light therapy is an affordable, natural, and non-invasive treatment option that can help stabilize your animal’s emotional highs and lows. And it costs less than a year’s supply of pet food.
At Kaiyan Medical, we recommend treating your animal for 30 minutes every day with red light therapy. Cat and dogs suffer from many conditions such as inflammation, arthritis, and infections. Light therapy gives you the chance to help treat your pet and reduce their pain and suffering.
How it works
How does red light therapy actually help to treat animals? While you may think the answer is complex, it’s not. Red light therapy delivers red and infrared light into the animal’s cells, boosting the body’s natural ability to heal.
Using either LEDs or LASER diodes, light penetrates through the skin, entering the body’s cells. Photoreceptors in your animal’s cells absorb the light’s energy, enhancing the natural healing process by stimulating the cells’ energy production.
The use of varying lights helps treat different areas of the body. For example, red light is easily absorbed by tissue rich in hemoglobin, helping to heal surface wounds.
Near-infrared light penetrated into deeper tissues within the body, entering muscles, joints, bones, tendons, and ligaments for extensive treatment. Combing red, green, and near-infrared light offers a well-rounded treatment for your animal.
What else light therapy can do for your cat?
The way light therapy stimulates cells can help treat several conditions in animals, including:
Clinical data has supported and proven light therapy’s effectiveness in treating animals. In one study, horses suffering from chronic back pain responded to red light therapy in less than three months of therapy, with 70% gaining the ability to train and compete. Other studies have also proven that horses treated with red light therapy experience faster tissue healing times.
If you’re considering treating your dog or cat with light therapy, the first thing you need to do is consult your veterinarian, ensuring it’s the right treatment option for your pet.
Light therapy treats various conditions; however, if your pet is experiencing severe SAD, they may need an extensive treatment plan. At Kayian Medical, we love our animals and want to provide them with the best support possible.

We’ve all been in the search to help us achieve perfect skin. But is it just a dream, or can it really be achieved? It looks like having light shined on your face may be the most important part of your skin routine.
Red light’s anti-inflammatory and collagen-building effects on the skin have been documented for years, showing its healing abilities. However, light therapy is branching out, including other light spectrums such as green, blue, purple, and amber, for different healing abilities.
Ellen Marmur, a New York dermatologist, said, It has just enough variety that people stay excited to use it.” While many at-home devices are small and require multiple treatments to cover the entire face, masks help solve this issue.
“It makes people feel good, like they’re taking care of themselves,” Dr. Marmur said. “You can treat your skin while doing other things, so it’s easier to form the habit of doing it every day.”
So How Does LED Work?
LED therapy, known as photobiomodulation, can alter biological matter using varying wavelengths of light.
Jared Jagdeo, associate professor of dermatology and director of the Center for Phototherapy, SUNY Downstate Health Science University, studies LED therapy. “You can alter the skin through photo-damaging with lasers, or photobiomodulation, which is a much more gentle way of changing the way the skin functions,” he said.
When asked why red light works particularly well with skin, he said, “There’s a specific receptor in the mitochondria of the skin cells that red light specifically acts upon. And that’s why red light is an ideal wavelength for changing the way the skin functions.”
Red light can pass through the skin, deeply entering tissue and stimulating the cell’s mitochondria, which results in anti-inflammation and the skin’s rejuvenation. Collagen is also produced in the dermis, smoothing out wrinkles and plumping the skin.
While blue light doesn’t penetrate deeply into the skin, it kills acne-causing bacteria on the skin’s surface. Green light, on the other hand, focuses on melanocytes, reducing excess melanin production.
Brain S. Biesman, assistant clinical professor of ophthalmology, dermatology, and ENT at Vanderbilt University Medical Center in Nashville, states that most red light therapy devices aren’t powerful enough to cause eye damage. “Just normal blinking and eye movements should be sufficient to protect the eyes,” he said. “But never stare at a bright light source.”
“As far as the F.D.A. is concerned, if I use CO2 laser resurfacing, it better work because of the amount of risk involved,” said Suzanne Kilmer, a clinical professor of dermatology at the UC Davis School of Medicine in Sacramento and director of the Laser and Skin Surgery Medical Group.
“Compare that to a home device,” Dr. Kilmer said. “If it doesn’t kill you, blind you or make things much worse, it’s probably going to get approved. So it’s actually more incumbent upon the people selling home devices to show efficacy. You have to trust the people who are selling them.”
“LED is real, but it’s probably not optimized yet,” Dr. Kilmer said.
With light therapy, various factors help determine the amount of light your skin needs: the light’s strength, the distance from the skin, the length of time the device is used on the skin, and the natural color of your skin.
“Some of these lights on the market are very weak, and they may not have enough energy output to actually have a biological effect,” Dr. Jagdeo said. “Imagine a glow stick. It produces a color. But you could shine it on your face all day, and it’s not going to change the way your skin works.”
Moreover, the medical community hasn’t determined the standardized dose for treating skin conditions such as hyperpigmentation and acne at home. Dr. Marmur chose her MMSphere dosing on Blu-U, an in-office blue light typically used as an alternative therapy for precancerous lesions.
“Consistent Sphere treatment for seven weeks will equal the energy given in the office with the Blu-U,” she said.
Another device, the Dr. Dennis Gross DRx SpectraLite FaceWare Pro, $435, releases red and blue light in a mask format, with each session lasting only three minutes. The mask’s LEDs are in contact with the skin, which may be a more effective treatment.
Dr. Jagdeo said, “This is a tremendously undertapped area in medicine. But LED light therapy is going to revolutionize the way home medical treatment is delivered for skin care over the next 10 to 15 years.”

Life without light is darkness. Light plays a vital role in our healthy life. Now the light is expanding the business scope in business for LIGHT THERAPY.
Light therapy also known as phototherapy is a simplified process, where the skin is precisely exposed before a light-emitting source on a routine. This light resembles natural light which helps to stimulate cells in the affected section.
Light Therapy has a notable history. It started back in 1903, when Niels Ryberg Finsen, developed a device that produced synthesized light. He was also awarded Nobel Prize in Medicine for this discovery. Later in 1938, a hospital in Massachusetts performed effective testing on patients with colored lights.

Wouldn’t it be great if we could each reduce a couple of inches off our waist without having to diet or exercise for so long? Losing weight and fat is one of the most common health goals, both for medical and cosmetic reasons. For years, millions of people have tried different pills, injections, “natural” herbs, and many products that are supposed to help us reduce weight. Unfortunately, these usually don’t work
Many people trying to lose weight just want to look better in the mirror, or at the beach. A wide variety of therapies to target fat and improve appearance are called “body contouring” or “body sculpting”, some surgical, others noninvasive. But many of them don’t work, or produce troublesome side effects. Green light therapy is completely natural & noninvasive and has proven to be an effective option for changing the way your body looks.
In the clinical trial NCT03647748 a double-blind, placebo-controlled randomized evaluation of the effect of Cellulize, a green light low-level laser system for aesthetic use for the non-invasive reduction in fat layer for body contouring and reduction of cellulite.
The Cellulize is a non-invasive green light system with a power output of 105mW/cm2, consisting of 150 light-emitting diodes (LEDs) that emit visible light at a nominal wavelength of 532nm ± 3nm (visible green light spectrum) and a spectral bandwidth of 10nm. Cellulize® is indicated for uses non-invasive dermatological aesthetic treatment for the reduction of circumference of hips, waist, and thighs. The Massager component is indicated for the temporary reduction in the appearance of cellulite.
Cumulative circumferences of waist, hip, left and right thighs for each patient was calculated before and after treatment. Three main points were concluded as a result of the study:
1. Cellulize causes immediate inch loss in subjects after a regimen of six treatments of 32 minutes (8 minutes on each of four positions) compared to individuals subjected to a placebo device for equivalent treatment. In a typical regimen, patients lost an average cumulative of 2.67 inches of circumference compared to the placebo average of 0.5 inches. This meets the anticipated primary outcome measure “Average Change in Inches of Total Circumference Measurements for the effect of Cellulize, a LED 532nm green light low-level laser system for aesthetic use for the non-invasive reduction in fat layer for body contouring from baseline measurements, and after treatment. ”
Figure 1, below, shows the graphical summary of inch loss for patients in the Cellulize active group and the Placebo control group respectively. Table 1 gives the mean values for both groups as well as the standard deviation for the “after” measurements, as well as 7-day and 14-day follow-ups relative to the “before” measurements for each patient:
2. While the durability of effect is also impacted by extrinsic factors after treatments such as diet, it was demonstrated that subjects were more likely to show continued inch loss upon following up with each subject at 7 days and again at 14 days. In general, patients undergoing active Cellulize 532nm green light continued losing some inch with an average continued loss of an additional 1.20 inches for a total average inch loss of 3.87 inches where average placebo measurements after 14 days yielded a net gain (not a loss) of 0.875 inches. This implies that the green light treatment meets the expected primary outcome of demonstrated durability of effect after a short -term follows up of 2 weeks.
3 Finally, the effect of Cellulize LED 532nm green light without any other intervention was measured for its effect on cellulite as part of the study. The Nurnberger-Muller Scale (NMS), a four-stage scale used as an industry standard to classify stage or degree of cellulite and to determine the change in stage or degree of cellulite following treatment intervention, was used to ensure consistent evaluation standards. Results from the active device as well as placebo both showed that cellulite, in general, did not decrease on the back of thigh/buttocks for subjects after a single treatment of 532nm green light. This result failed to meet the anticipated primary outcome measure of decreasing the appearance of cellulite as a measure of the Nurnberger-Muller Scale (NMS) from baseline to completion of treatment for the thigh/buttock area.
