Are You A Night Owl? Staying Up Late May Risk Your Health, Study Finds



A recent study has shed light on the potential health risks faced by night owls. These individuals, who prefer staying up late and sleeping in, may be at a higher risk of developing type 2 diabetes and engaging in unhealthy lifestyle habits.

Staying Up Late May Risk Your Health, Study Finds

The research, led by Sina Kianersi, a postdoctoral research fellow at Brigham and Women’s Hospital and Harvard Medical School, discovered that night owls had a staggering 72% increased risk of developing type 2 diabetes over an eight-year study period when compared to early birds.

The study also uncovered strong associations between the night owl chronotype and several unhealthy behaviors known to contribute to chronic diseases like diabetes.

Night owls were more likely to have poor dietary habits, be less physically active, consume higher quantities of alcohol, maintain an unhealthy body mass index (BMI), smoke, and experience either too much or too little sleep, deviating from the recommended seven to nine hours per night.

Even after accounting for these unhealthy habits, the risk of type 2 diabetes for night owls decreased to 19% when compared to early birds. Dr. Bhanu Prakash Kolla, a sleep medicine specialist at the Mayo Clinic, suggests that there might be a genetic predisposition or other unaccounted factors contributing to this risk.

It’s important to note that everyone has an internal body clock or circadian rhythm that regulates various bodily functions, including sleep.

Night owls have a delayed release of melatonin, making them more alert and active in the afternoon and evening, while early birds are more active in the morning.

The disruption of these circadian rhythms due to staying up late can lead to hormonal changes, temperature regulation issues, and metabolic disturbances, increasing the risk of diabetes and other chronic illnesses.

Early birds tend to excel academically and remain active throughout the day, which could explain their lower risk of cardiovascular disease.

The study, which followed nearly 64,000 nurses participating in the Nurses’ Health Study II, found that night owls who worked during the day had a higher risk of developing diabetes compared to those with different work schedules.

In conclusion, while lifestyle factors play a significant role in the risk of developing type 2 diabetes, genetics and circadian rhythms also contribute.

Night owls can reduce their risk by maintaining a healthy lifestyle, which includes moderating alcohol intake, quitting smoking, increasing physical activity, and ensuring adequate sleep.

Personalized work schedules that align with an individual’s chronotype could also be beneficial in reducing health risks associated with being a night owl.

Study Reveals the Complex Relationship Between Calorie Restriction and Longevity

For years, scientists have speculated that consuming fewer calories might help people live longer. A recent study has shed new light on this topic, suggesting that the relationship between calorie restriction and longevity is more complex than previously thought.

“We’ve known for nearly 100 years that calorie restriction can extend healthy lifespan in a variety of laboratory animals,” stated one researcher last year to CNN.

However, the new study seems to indicate a more intricate relationship between calorie restriction and living to a ripe old age.

“There are many reasons why caloric restriction may extend human lifespans, and the topic is still being studied,” explained Waylon Hastings, lead author of the study and postdoctoral researcher. “One primary mechanism through which life is extended relates t

Exercise Cuts Heart Disease Risk by Lowering Stress, Study Finds

New research indicates that physical activity lowers the risk of cardiovascular disease, in part by reducing stress-related signaling in the brain. The study, led by investigators at Massachusetts General Hospital and published in the Journal of the American College of Cardiology, found that people with stress-related conditions such as depression experienced the most cardiovascular benefits from physical activity.

To assess the mechanisms underlying the psychological and cardiovascular disease benefits of physical activity, Ahmed Tawakol, an investigator and cardiologist in the Cardiovascular Imaging Research Center at Massachusetts General Hospital, and his colleagues analyzed medical records and other information of 50,359 participants from the Mass General Brigham Biobank who completed a physical activity survey.

A subset of 774 participants also underw

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
