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.

What Is Blue Light?

How Does Blue Light Impact Circadian Rhythms?

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.

Health Consequences Of Disrupted Sleep

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.

Devices That Emit Blue Light

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

How To Minimize Blue Light Exposure

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.

You've probably seen gallon jugs with stuff like "BORG o'clock somewhere" scrawled on them in Sharpies, often showing up at parties. Well, there's actual research on them now, and it's not great.

The study by Rutgers University, published in the Journal of Studies on Alcohol and Drugs, surveyed over 100 college students about their BORG habits. The study finds significant health risks.

What Is BORG?

BORG stands for "Blackout Rage Gallon," and it's basically a personal-sized jug loaded with liquor, water, and whatever flavoring you're into. It started gaining traction around 2020 and hasn't slowed down since the hashtag #borg has racked up millions in views on TikTok alone.

Here's the number that stands out, though. A full BORG can pack up to a fifth of liquor. That's about 17 standard drinks. In one jug. And it is meant for one person.

The study pointed out that drinking games have always been part of college culture. But BORG drinks might be worse than most, mainly because of how they're made. Mixing hard liquor with sweet flavors can make people drink more without realizing how much alcohol they're actually consuming, and the fact that people often share sips of each other's jugs only adds to the risk.

"Excessive drinking in young adults has been fueled by drinking games for many decades. But the mixing of hard liquor and additive flavorings in BORGs may be particularly harmful given the sweetness of the beverage and the lure of sharing one's BORG and tasting others' concoctions," said lead researcher Andrea King, a professor of psychiatry and behavioral neuroscience at the University of Chicago, US.

When Can BORG Drinks Go Wrong?

The actual numbers from the study are rough. Almost a third of students said they'd blacked out from a BORG at some point, not just "drunk," actually blacked out, meaning their brain stopped saving memories from that stretch of time.

Nearly 20 percent of students said they threw up, and nearly 6 in 10 admitted to saying or doing something embarrassing. And this is just the students who actually admitted to having done this. The actual count could be much higher. Some cases were serious enough to end in injuries or trips to the emergency room.

According to the World Health Organization, there is no safe level or risk-free amount of alcohol consumption that does not affect health.

BORGs: The ‘Safe Drinking’ Myth

What's even more interesting, however, is how this trend began in the first place. BORGs were initially promoted on social media as the more responsible choice when it came to drinking. The idea was for everyone to bring their own jug instead of sharing cups, so as to avoid the spread of germs during the pandemic.

Some recipes online even threw in electrolytes or caffeine, supposedly to dodge hangovers or keep people from getting too drunk. Students still shared their BORGs constantly, and the added ingredients did nothing to stop the harmful effects of drinking so much alcohol at once.

Even knowing all this, however, a lot of students said they're not planning to stop. That's part of why this study seems to emphasize the fact that awareness matters so much, both for students and for their parents.

As King put it, "There are choice points along the way, ranging from whether to attend a BORG event, and if one does attend, whether to bring a BORG beverage and how much (if any) alcohol to put in the beverage. It doesn't have to be all-or-none, as being aware and mindful to minimize risks can be key."

Alzheimer’s disease is normally seen as a disease of old age, something that starts when memory starts to fail in the 70s or 80s. But science has a totally different narrative. Alzheimer’s is not something you ‘catch’ suddenly in old age. It’s a sluggish, degenerative disorder that develops slowly over decades. When a person begins to forget names, ask the same questions, or have trouble with everyday chores, there may have been damage to the brain for years.

This is why neuroprotection should start much earlier, ideally in our 30s and 40s.

Today, most patients only see the neurologist when the symptoms are obvious. Unfortunately, at this stage the disease process has already progressed and therapy options are limited. Doctors and health professionals need to be more open about prevention, to teach younger folks that brain health is established well before retirement age.

Our modern lifestyle is a silent neurological risk. A busy life is making chronic stress, poor sleep, physical inactivity, bad diets and extended hours of sitting normal. But these common activities may be quietly contributing to inflammation that’s damaging blood arteries and brain cells over time. Studies increasingly connect mid-life problems like obesity, diabetes, hypertension and sleep difficulties to a greater risk of dementia in later life.

Sleep is particularly important for removing such toxic substances from the brain. Constant stress boosts cortisol levels, which may interfere with memory areas. A sedentary lifestyle lowers the blood supply to the brain and undermines cognitive resiliency. Something that seems inconsequential today may be important decades from now.

The good news is that prevention is effective. Regular exercise, good sleep, management of stress, social activity, mental stimulation and regular health checks can all help protect the brain. Neuroprotection is not about fear; it’s about awareness and action.

What we decide to do in our 30s and 40s is not just about our careers or lifestyles; it’s about the health of our brains in our 70s and 80s. We need to change the conversation around Alzheimer’s from late-stage therapy to early-life prevention.

From upscale salons to local aesthetic clinics, a quick IV infusion of glutathione is being offered for skin brightening and anti-ageing. But these increasingly popular cosmetic drips may neither be legal nor safe and may carry several health risks, doctors have warned.

Glutathione is an unapproved therapy that involves risks at many levels, including toxins. As per the US FDA, injectable/IV glutathione is not FDA-approved as a safe compounded sterile injectable, carrying high risks of contamination and severe adverse reactions.

Warning Against Glutathione IV Drips

In a social media post on X, noted hepatologist Dr Cyriac Abby Philips called out an advertisement for a clinic offering glutathione IV drips, promising skin whitening.

He warned people to “absolutely” avoid it, as the effects on skin may be temporary but carry long-term health risks from kidney to liver dysfunction, and potentially fatal skin reactions.

“Because the body continuously produces melanin, any potential lightening effect is temporary. Once the extreme systemic doses are stopped, the skin's natural pigmentation returns,” Dr Abby said.

Further, he also stated that the procedure is mostly offered by "cosmetologists" or commercialized dermatology clinic chains. As cosmetology is not a recognized medical degree or a protected medical title under the National Medical Commission in India, people claiming to be "cosmetologist" is not really a medical practitioner, but merely certified "coaches" or "wellness experts".

Poor Evidence Supporting IV Glutathione

The expert, better known as “LiverDoc” also noted that the clinical evidence supporting IV glutathione is exceptionally poor.

“The administration of IV glutathione in dermatology and cosmetology clinics is a lucrative marketing trend that operates outside the bounds of evidence-based medicine”.

“Marketing claims rely heavily on anecdotal reports and a single, widely criticized trial that suffered from a tiny sample size, poor study design, and unreliable evaluations,” he added.

FDA Warning Over Glutathione IV Treatments

“Because IV glutathione is not approved for cosmetic use, the solutions utilized in wellness clinics and med-spas are typically sourced from "compounding pharmacies". This bypasses standard pharmaceutical manufacturing regulations, introducing severe risks”.

Dr. Abby explained that a "compounded drug" is a custom medication created by a pharmacist or physician who combines, mixes, or alters ingredients on their own.

He cited how in August 2026, the US FDA issued an urgent safety warning after dozens of patients experienced potentially fatal infection (sepsis)-like symptoms — including fever, chills, low blood pressure, and hospitalization — following glutathione IV treatments.

“Clinics were found to be compounding IV drips using dietary-supplement-grade powder, which contained dangerously high levels of bacterial endotoxins. Administering high doses has been linked to severe adverse effects, including anaphylaxis, acute kidney and liver dysfunction, and potentially fatal skin reactions like Stevens-Johnson syndrome and toxic epidermal necrolysis (SJS and TEN),” Dr Abby said.

India Tightens Rules Around Injectable Cosmetics

In May 2026, the Central Drugs Standard Control Organisation (CDSCO) tightened rules around cosmetic use.

In a new public notice issued, the CDSCO stated that cosmetic products that come in injectable form do not fall under the definition of cosmetics under the law. It said that such products are not permitted for use by consumers, professionals, or aesthetic clinics.

Other Potential Health Risks

According to the Philippines FDA, given that glutathione affects the production of melanin — the pigment that gives human skin, hair and eyes their colour — there are theoretical concerns about the long-term skin cancer risk.

Other potential risks include transmission of infectious agents, such as HIV, hepatitis C and B. This is of particular concern when a non-medical practitioner administers this treatment or it is done in a non-sterile facility.
