Beware of hitting that snooze button too hard on weekends! Sleeping in on weekends could be bad for your health: says a recent study!

Sleeping In On Weekends Could Be Bad For Your Health

London’s King’s College researchers delved into the intriguing realm of “social jet lag,” a term that describes how irregular sleep patterns mess with your body’s internal clock, potentially causing health issues.

The study, published in the European Journal of Nutrition, involved nearly 1,000 adults whose blood, stool, and gut microbiome were scrutinized. The participants were divided into those who stuck to a steady sleep schedule and those who danced to a more erratic bedtime beat.

Surprisingly, even a mere 90-minute shift in sleep midpoint wreaked havoc on the composition of gut bacteria.

In a recent study led by senior author Dr. Wendy Hall from the School of Life Course & Population Sciences, researchers revealed a noteworthy connection between slight variations in sleep timings throughout the week and differences in gut bacterial composition.

Dr. Hall emphasized the significance of this discovery, marking it as the first study to establish such a link. The investigation, conducted as part of the Zoe Predict study, which is recognized as the most extensive ongoing nutritional study of its kind, shed light on the potential impact of circadian rhythms on the gut microbiome.

The study uncovered that individuals experiencing “social jet lag” – misalignment between their social schedule and internal body clock – exhibited lower diet quality. This was characterized by a decrease in the consumption of fruits, vegetables, and nuts, coupled with an increase in the intake of sugary beverages.

Such dietary patterns were found to influence the gut microbiome composition. Notably, three out of the six identified microorganisms in socially jet-lagged individuals’ gut were associated with adverse health outcomes, including indicators for obesity, inflammation, and cardiovascular risk.

The research also indicated that maintaining consistent sleep patterns – adhering to regular bedtime and wake-up routines – could be a simple yet impactful lifestyle adjustment with potential benefits for gut microbiome health.

Dr. Sarah Berry, Chief Scientist at health science company Zoe, emphasized the significance of this finding, suggesting that aligning sleep schedules could positively influence gut health.

This study contributes to the growing body of research investigating the interplay between circadian rhythms, sleep patterns, and gut microbiome composition.

The significance of healthy sleep patterns in promoting overall health has been highlighted in previous studies, which indicated potential risks associated with both excessive and insufficient sleep.

Research from Columbia University’s Mailman School of Public Health underscored the potential of improved sleep quality in reducing the risk of cardiovascular diseases. As the exploration of these interconnections continues, the implications for public health become increasingly evident.

While it’s no surprise that extremes in sleep – too much or too little – have their own set of problems, the King’s College study sheds light on the subtler impact of sleep irregularities.

So, next time you consider trading sleep for a lazy weekend lie-in, remember, your gut might not be as thrilled about it as you are. Maintaining a consistent sleep schedule could be a simple yet effective step towards a healthier you.

Lack of Sleep Linked to Rising Cases of Non-Alcoholic Fatty Liver Disease, Warns Expert

In a recent revelation, lack of adequate sleep has been associated with a concerning rise in cases of non-alcoholic fatty liver disease (NAFLD), according to insights shared by medical experts. As sleep deprivation continues to plague a significant portion of the population, the implications on public health are becoming increasingly alarming.

More than a third of adults in the United States fail to attain the recommended seven to eight hours of sleep each night, a trend that has sparked growing concerns among healthcare professionals. The scarcity of shuteye, it turns out, can have profound effects beyond daytime fatigue and drowsiness.

Study Explores Impact of Residential Green Space on Childhood Mental Health

A recent study published in JAMA Network Open investigates the relationship between residential green space and externalizing and internalizing symptoms in children. Conducted in the United States, the study aims to identify potential factors that can mitigate risks associated with childhood mental health disorders.

According to the study, up to 40% of children in the US may meet the criteria for mental disorders by adulthood, with an increased prevalence of externalizing (e.g., rule-breaking and aggression) and internalizing (e.g., depression and anxiety) symptoms.

Researchers suggest that environmental factors, such as green spa

Study Links Volatile Work Hours to Burnout and Health Issues

A recent study conducted by NYU Social Work professor Wen-Jui Han has shed light on the detrimental effects of volatile work hours on both physical and mental health. The research, which analyzed data spanning over 30 years, found a significant correlation between irregular work hours and increased health concerns.

The study, which examined the work schedules and sleep patterns of over 7,000 Americans, revealed that individuals working rotating shifts were more prone to health problems such as diabetes, obesity, and heart disease. The primary factor contributing to these issues was identified as a disruption in sleep patterns caused by inconsistent work schedules.

Jamaica Shiers, a representative from Path Behavioral Health in Salt Lake City, emphasized the prevalence of burnout among adults, attributing it to the pressure to maintain peak performance at al

New Study Suggests Balanced Diet Better Than Vegetarian Diet for Brain Health

In a groundbreaking study published in Nature Mental Health, researchers have shed light on the relationship between dietary patterns and brain health. The study suggests that a balanced diet, comprising various food types, may be superior to a vegetarian diet in supporting mental well-being and cognitive function.

The research, which analyzed data from nearly 182,000 participants, focused on four main dietary patterns: starch-free/reduced starch, vegetarian, high-protein/low-fiber, and balanced diet. Participants’ food preferences were examined in categories such as fruits, vegetables, starches, protein, and snacks.

Optometrists Share Expert Tips to Prevent Eye Sunburn as Summer Approaches

As we gear up for the longer and sunnier days of summer, it’s essential to protect our eyes from potential harm caused by UV rays. Optometrists have shared expert advice on how to prevent eye sunburn and what to do if you experience it.

Eye sunburn, also known as photokeratitis, occurs when the sun’s UV rays damage the cornea and conjunctiva, leading to symptoms like pain, redness, sensitivity to light, and blurry vision. While discomforting, these symptoms typically resolve within 24 hours as the cornea heals.

Moreover, prolonged exposure to UV rays can also damage the retina, particularly if one stares directly at the sun. This damage, known as solar retinopathy, can cause distorted vision or even vision loss.

Unfortunately, retinal damage is often permanent due to the lack of pain receptors in the ret

Researchers Share 5 Strategies to Complete Stress Cycle and Prevent Burnout

In a recent article published by The Conversation, Theresa Larkin and Susan J. Thomas, both associate professors at the University of Wollongong, shed light on the significance of completing the stress cycle to avoid burnout and depression. Chronic stress, they warn, can lead to severe health issues including heart disease, stroke, and diabetes.

The authors delineate the three stages of the stress cycle: perceiving the threat, experiencing the fight-or-flight response driven by stress hormones like adrenaline and cortisol, and finally, achieving relief which signifies the completion of the cycle.

While stress is an inevitable part of life, remaining in the heightened state of fight-or-flight can have detrimental effects on both physical and mental health.
