World Diabetes Day 2025: Does Screen Time Before Bed Affect

The rapidly increasing ratio of diabetic patients has created an alarming situation. Doctors and researchers are continually evaluating the factors that disrupt blood glucose levels. For this purpose, they considered different core reasons.

WHO World Diabetes Day 2025 Campaign emphasizes that “Supporting well-being and self-care empowers people with diabetes at every age. Sleep hygiene and lifestyle factors, including screen use, are part of integrated care.”

Similarly, a news medical study confirms that “Late sleep timings or inadequate sleep durations negatively impact glucose regulation, a process critical to preventing diabetes and other metabolic disorders.”

Years ago, it was commonly thought that stress and anxiety could increase blood sugar. But in recent analysis reports, bedtime screen habit is the top reason for hormonal changes. People with a habit of scrolling and streaming reported disrupted sleep patterns, which reduced their body’s control over glucose levels.

What Doctors Say About Screens and Blood Sugar

The blue light of the screen keeps the brain in start mode. It’s constantly trying to stay awake to reduce the melatonin release. A lack of this sleep-promoting hormone or its delayed release results in poor sleep quality. The body loses its natural resistance to insulin, and eventually the sugar level starts to rise.

The famous Indian endocrinologist, Dr. Shehla Shaikh, who is an endocrinologist, also stated that screen use at night is the primary cause behind diabetes. She said, “Blue light from screens suppresses melatonin, delays sleep onset, and reduces sleep quality. Poor sleep directly impairs insulin sensitivity, which can raise blood sugar levels overnight.”

He further added that “When patients use phones or laptops before bed, they often experience disrupted circadian rhythms. This disruption makes glucose regulation harder, especially in people already at risk of type 2 diabetes.”

In a YouTube awareness session, she stated, “We now have strong evidence that late-night screen exposure increases the risk of insulin resistance. Even healthy individuals show higher fasting glucose after nights of poor sleep linked to screen time.”

Simple Changes You Can Make Tonight

The latest reports and expert reviews do not mean leaving the screen entirely. But throughout their reviews, they shared that a person should leave all types of screens for at least one hour before going to bed.

Dr. Bhawna Attri, Endocrinologist, emphasized that “Lifestyle modification is central to diabetes prevention. Sleep hygiene, including reducing screen time before bed, is as important as diet and exercise in maintaining stable blood sugar.”

This time is enough to relax the brain, allowing it to naturally release the sleep hormone. For better sleep, you can find an alternative that has no side effects. For example, you can read a story, stretch, or perform any meditation exercise. Their constant performance not only improves sleep but also increases insulin resistance.

Dr. Chuck Dinerstein, MD, MBA, said, “Insulin sensitivity has a bedtime. Aligning sleep and light exposure with circadian rhythms is critical. Late-night light exposure, including screens, disrupts this rhythm and worsens glucose control.”

The Bigger Picture for Diabetes Care

In today’s digital world, screen time has become a significant risk to our lives. It not only affects our sleep but also causes several other complications. World Diabetes Day 2025 not only reminds us of the importance of managing this disease but also encourages us to learn how to control it.

According to Wildwood Lifestyle Center, “Evidence is quickly mounting that individuals with diabetes may improve their glucose levels by tightly regulating their exposure to light. Evening light exposure is one of the major culprits promoting insulin resistance.”

It reminds us that medicine is not only the solution for insulin resistance, but that sometimes small lifestyle changes can yield satisfactory improvements.
