As temperatures drop and flu season gears up, many people start thinking about how to “boost” their immune system. The truth is, immunity isn’t about a quick fix—it’s about daily habits that strengthen your body’s defenses over time. The good news? Small, consistent choices right now can make the difference between catching every bug that goes around and staying resilient all winter long.
Flu season usually peaks between December and February, but cases start climbing well before then. Add shorter days, colder weather, and more time indoors, and your exposure risk rises quickly.
During this season, the immune system is working overtime. Stress, lack of sleep, and poor diet can weaken your defenses, making you more vulnerable not just to the flu, but also RSV, colds, and other infections. That’s why early winter is the ideal time to reset and give your body the tools it needs to fight back.
Research shows that long-term immune health is built on simple, everyday habits:
None of these are quick hacks—they’re sustainable steps that keep your immune system strong throughout the season.
Even with great habits, sometimes you need more targeted help. Consider:
​​​​​​​Pay attention to warning signs like persistent fever, shortness of breath, or extreme fatigue. These could mean it’s more than just a seasonal bug.

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.

"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."
