World Diabetes Day 2025: Expert Tips to Manage Diabetes Effectively During Winter

World Diabetes Day, observed annually on November 14, serves as a global platform to highlight the escalating burden of diabetes—a chronic condition that saw its prevalence surge from 200 million cases in 1990 to 830 million in 2022, according to the World Health Organization. In India, often dubbed the "diabetes capital of the world", millions grapple with this metabolic disorder, which, if unmanaged, can precipitate severe complications, including kidney failure, neuropathy, and vision loss. As winter settles across the country with dropping temperatures, reduced daylight, and heightened pollution levels, individuals with diabetes face amplified challenges that demand tailored management strategies. Dr Ambrish Mithal, Group Chairman of Endocrinology & Diabetology at Max Super Speciality Hospital in Saket, emphasises that proactive care during this season is crucial to mitigate risks and maintain glycaemic stability.

Cold weather introduces physiological and behavioural shifts that can disrupt blood sugar control, such as diminished physical activity due to shorter days and indoor confinement, cravings for calorie-dense comfort foods, and impaired circulation that slows insulin absorption. Dr Mithal notes that people with diabetes are 60% more likely to require hospitalisation for flu-related illnesses, with poorer outcomes exacerbated by seasonal respiratory infections and pollution spikes that trigger inflammation and insulin resistance. Furthermore, limited sun exposure depletes vitamin D levels—vital for insulin sensitivity—and may induce seasonal affective disorder (SAD), where stress and low mood further destabilise glucose readings. These interconnected factors underscore the need for vigilant monitoring, ideally through Continuous Glucose Monitoring Systems (CGMS), to capture real-time fluctuations influenced by diet, exercise, and medication.

Effective winter management hinges on a multifaceted approach, beginning with frequent glucose checks and timely medication reviews with an endocrinologist to adjust insulin or oral agents as needed. Vaccination against flu and pneumonia remains a cornerstone, alongside indoor exercise routines like yoga, resistance training, or stair climbing to compensate for curtailed outdoor activity. Dr Mithal advocates leveraging midday sunlight for walks when pollution is lower and incorporating seasonal, nutrient-rich foods such as bajra, green leafy vegetables, amla, garlic, and nuts, which bolster fibre intake and antioxidant defences. Foot care emerges as particularly critical amid dry air that cracks skin, increasing infection risks; daily inspections, moisturising (avoiding inter-toe areas), and warm footwear are non-negotiable to prevent wounds that heal slowly in diabetic patients.

Avoiding festive indulgences like ghee-laden parathas, deep-fried snacks, and halwa in moderation helps curb glycaemic spikes, while recognising red flags—persistent hyper- or hypoglycaemia, non-healing foot injuries, or signs of depression—prompts immediate medical consultation. Dr Mithal reassures that with disciplined adjustments, winter can be navigated successfully, allowing individuals to enjoy seasonal offerings without compromising health. This holistic framework not only aligns with World Diabetes Day's ethos of awareness and action but also empowers patients to transform seasonal hurdles into opportunities for sustained well-being.

As India confronts its diabetes epidemic amid climatic shifts, expert-guided vigilance ensures that winter's chill does not translate into health crises, reinforcing the message that informed lifestyle tweaks can yield stable control and enhanced quality of life year-round.
