You plug in the tree, crank the heater, and admire that cozy glow.
It’s peak holiday comfort — until your eyes start burning or the room feels stuffy.
It’s not just “winter dryness.” Both holiday lights and indoor heaters can quietly irritate your eyes and affect air quality.
Let’s break down what’s really happening 👇
LED lights are energy-efficient, but that sharp blue-white glare can strain your eyes.
Prolonged staring at bright or blinking lights causes fatigue, headaches, and dryness.
Children’s eyes are more sensitive to flicker and brightness.
Decor tip: use soft-white or warm LEDs, and keep strands out of direct sightlines.
💬 If your eyes feel gritty after decorating, it’s not allergies—it’s glare fatigue.
Heaters make rooms cozy but zap humidity fast.
That dry air leads to itchy eyes, irritated sinuses, and even increased static.
Keep eye drops handy for instant relief.
While you’re fixing eye irritation, don’t ignore the air you’re breathing.
Check heater filters before turning them on.
Keep vents unblocked to prevent overheating.
And yes—test your carbon monoxide detector before guests arrive.
A little maintenance now prevents the “mystery headaches” that sometimes strike during gatherings.
If your eyes feel tired or dry:
Blink often, look away from lights for 20 seconds.
Use preservative-free lubricating drops.
Step outside for a few minutes of natural light.
Your eyes will thank you for every break.
If dryness, redness, or dizziness stick around even after you adjust lighting and airflow, check in with CallOnDoc. Quick online visits can rule out infection, allergies, or CO exposure—without leaving home.

Warning Signs and Symptoms of Prediabetes
More than 1 in 3 Americans—approximately 96 million adults—have prediabetes, and an estimated 80% do not know it. Prediabetes often develops silently, without obvious symptoms, making early detection challenging. Because symptoms are usually mild or absent, many people do not realize they are at risk until blood sugar levels progress to type 2 diabetes.
Understanding what prediabetes is—and how to intervene early—can significantly reduce your risk of developing diabetes, especially if you have a family history or other risk factors.

National Diabetes Awareness Week
Diabetes affects the body’s ability to get energy from glucose. People with this condition are either not able to produce sufficient insulin (Type 1) or are unable to use the insulin their body makes to its full potential (Type 2).
When either of these things occurs, an excess of sugar remains in the blood. Left unchecked, too much sugar in the bloodstream can lead to the development of serious problems like kidney and heart disease, as well as vision loss. Unfortunately, 20% of people with diabetes may never know they have it.

Feedback from our amazing patients!
"I can’t believe I did not know about this kind of service! This was absolutely perfect for my health concern and they were able to provide me with the necessary medication and with such cinch. Completely recommended this service. For minor health concerns, this can save you an unnecessary and costly trip to an urgent care center."
"Amazing!! Easy and fast! I didn’t have to take my 4 year old into an urgent care where only god knows what germs are there. The doctor sent the script right to my pharmacy within minutes!!!"
"I would give 10 stars if I could! CallonDoc is literally the reason I am recovering instead of suffering as I write this. I was skeptical at first, but I’m not kidding when I tell you I got prescribed my antibiotics and picked it up at the pharmacy within 2 hours. So instead of waiting & paying around 300$...I paid 40$!! I’m very pleased."
