Blue light emitted by devices like smartphones, computers, and televisions is becoming a major factor disrupting our sleep cycles. Research reveals that a significant number of Americans use electronic devices close to bedtime, contributing to poor sleep quality. Reducing exposure to blue light, particularly in the evening, is a simple yet effective way to help your body prepare for restful sleep.
Circadian rhythms are 24-hour cycles that control essential bodily functions, including sleep. Light is the primary factor that aligns these rhythms with day and night. Historically, exposure to sunlight during the day helped set our body clocks, signaling when to be awake and when to sleep. However, the widespread use of artificial lighting and electronic devices has introduced more light exposure after dark, disrupting these natural cycles.
Blue light, in particular, has the strongest impact on circadian rhythms. During daylight hours, blue light helps us feel alert by stimulating the brain, raising body temperature, and increasing heart rate. But in the evening, exposure to blue light can confuse the body’s internal clock, suppressing melatonin—the hormone responsible for making us feel sleepy. As a result, our brains may remain in “daytime mode,” preventing us from winding down for the night.
Persistent disruption of circadian rhythms can lead to a range of health issues, including metabolic disorders, poor mental health, and increased risk for conditions like depression and anxiety. Furthermore, the inability to sleep well at night affects cognitive performance, mood, and overall well-being. Chronic exposure to blue light in the evening may significantly contribute to these negative health outcomes.
Many common devices in our daily lives emit blue light, including:
- Smartphones and tablets
- Computer monitors and laptops
- Televisions and e-readers
- LED and fluorescent lighting
- Video game consoles
To reduce the effects of blue light on your sleep, here are some practical strategies:
1. Turn off screens before bed: Try to avoid using electronic devices at least two to three hours before bedtime. Reducing screen time helps prevent blue light from interfering with melatonin production.
2. Adjust your lighting: Dim your home’s lights or switch to warmer-toned lighting in the evening. You can also use lamps with red or orange light, which are less likely to impact your circadian rhythms.
3. Night mode settings: Many smartphones and computers have a "night mode" feature that reduces blue light emission. Make use of these features to limit exposure in the hours leading up to bedtime.
4. Blue light-blocking glasses: Special glasses designed to filter out blue light may be helpful for some individuals. These glasses can block or reduce the melatonin-suppressing effects of blue light.
5. Apps for blue light reduction: There are several smartphone and computer apps available that reduce blue light emission, allowing you to use your devices before bed without disturbing your sleep.
6. Create a sleep-friendly environment: If you can’t control light sources in your bedroom, consider using an eye mask to block out ambient light and promote better sleep.

Irritable Bowel Syndrome (IBS) is a common but often overlooked gastrointestinal disorder; as a result, IBS is very prevalent, with less than 15% being diagnosed.
Individuals frequently experience recurrent symptoms such as bloated abdomen, abdominal pain, gas, diarrhea, or constipation, and normalize these symptoms over time or attribute them to "something they ate" or everyday stresses. Therefore, IBS remains undiagnosed for many years.
Why Diagnosis Is Often Delayed
One reason for this delay in being diagnosed is that the symptoms occur intermittently. It is also important to note that the presentation of these symptoms is inconsistent and unpredictable; there may be episodes where the IBS can last many days, and then completely resolve, thus providing a false sense of relief. Therefore, many individuals choose to delay consulting with a physician due to their belief that the symptoms they are experiencing are not serious.
Stigma Around Digestive Health
Another contributing factor is that there is still a degree of reluctance or discomfort associated with discussing problems related to the gastrointestinal tract openly; this only further complicates under-reporting statistics.
A ‘Functional’ Disorder Adds to Confusion
Finally, IBS is a functional disorder. Therefore, routine diagnostic testing will not reveal any visible abnormalities. Many patients may assume that the symptoms they are experiencing are not "real" or are not significant enough to warrant seeking medical attention, even though the discomfort they experience can be quite significant and affect their daily lives.
If you continually ignore symptoms of IBS, it will hurt your quality of life, productivity, and mental health. If you have persistent discomfort, you are likely to develop anxious feelings about eating, socializing, and travelling. Furthermore, if you don't manage your symptoms, you may experience a combination of untreated IBS with one or more other illnesses that are either gastrointestinal or metabolic; consequently, establishing the correct diagnosis for your IBS will be increasingly difficult as time goes on.
It is of the utmost importance to identify and respond to early warning signs of IBS as quickly as possible. A thorough evaluation can rule out other illnesses and provide a pathway for appropriate management, including dietary modifications, stress management techniques, and, if necessary, medical treatment.
Once you address your IBS, you will experience better control of your symptoms and eliminate the long-term consequences of IBS, both physically and psychologically.
Colorectal Cancer is not only one of the most common and deadly cancers, but is also one of the most preventable ones.
Unlike many other cancers, patients have a clear window of opportunity to stop it before it even begins. Almost always, these cancers start as small growths called polyps or precancerous lesions on the inner lining of the colon or rectum.
There is a long interval of time before polyps develop into cancer. During this time, they can be removed if they are identified. If a doctor removes a precancerous polyp during a routine screening, they would not only have nipped the cancer in the bud, but would have also prevented it from occurring.
However, there is a persistent taboo surrounding discussing bowel movements and other risk factors, and public understanding of its symptoms and crucial screening procedures frequently lags.
Dr Jeremy Clark, a consultant general surgeon specializing in colorectal diseases at Nuffield Health in Brighton, has underscored five critical warning signs the public must recognize, The Independent reported.
1. Blood in stool
“Passing blood when you go to the toilet is a worrying feature that you should flag to your GP,” Clark said, adding that the color can vary from bright red to almost black.
“If you see blood in the stools, particularly darker-colored blood or blood that’s actually mixed in with the stools, just once, and it’s significant, that should be reported to your doctor straight away. Don’t wait for that to keep on happening,” he added.
2. Changes in Bowel Habits
Dr. Clark stated that although more constipation may not be a risk factor, any sudden changes in bowel movements that last for a couple of weeks and do not go back to normal must be checked.
“If your bowels go from working once a day like clockwork, and then suddenly you’re going two or three times a day, and the bowels are a bit looser, that’s something that needs to be looked into,” the expert added.
3. Abdominal pain
Dr Clark highlighted that bowel cancers can cause abdominal pain, even in the initial days.
4. Bloatedness
The feeling of being 'quite often’ bloated may also indicate that something is going wrong in the bowel, Dr. Clark said.
5. Unexplained weight loss
Bowel cancers can impact digestion and cause weight loss

Dr Clark said that as these symptoms are common with other conditions, such as hemorrhoids or irritable bowel syndrome (IBS), people often ignore or easily dismiss these symptoms. He urged patients not to ignore and visit their doctor if they notice any of these symptoms.

What Is Colorectal Cancer?
The American Cancer Society notes that colorectal cancer is a cancer that starts in the colon or the rectum. Colorectal cancer impacts around 1.9 million people every year, noted the World Health Organization (WHO) as per its 2022 data.
It is a disease of the large bowel and a type of cancer that originates from the rectum or colon. A person's colon, cecum, rectum, and anus make up the large intestine.
According to experts, if you are above 45 years of age or have high-risk factors, you need to take the initiative to be screened.
The FIT (Fecal Immunochemical Test) is a simple, non-invasive at-home stool test kit that can collect a small sample of your feces, which can then be tested.
“If it comes back as positive, that means there is blood in your stools which needs to be investigated,” Clark said, adding that the next step is typically the Colonoscopy – the gold standard.
CBT is a structured way to deal with crises and respond with greater awareness. (Photo credit: AI generated)
Cognitive Behavioural Therapy (CBT) is often mentioned in conversations around mental health, yet its depth and practical relevance are not always fully understood. Rooted in the connection between thoughts, emotions, and behaviours, CBT offers a structured way to recognise patterns, question unhelpful narratives, and respond with greater awareness. Rather than offering quick fixes, it equips individuals with tools that can be applied in everyday situations, making it both accessible and effective. Here’s a closer look at what truly defines CBT and how it works in real life. Aanandita Vaghani, Founder and Mental Health Counsellor at UnFix, listed the five key things everyone must know before considering CBT.
At its core, CBT is not about eliminating difficult thoughts or emotions but about changing your relationship with them. It invites you to step out of autopilot, question familiar patterns, and respond with greater awareness and intention. When approached thoughtfully, often alongside other therapeutic tools, it becomes less about fixing yourself and more about understanding yourself. And in that understanding lies the ability to navigate life with more clarity, flexibility, and choice.
