Lack of sleep can make you look old and gloomy

September 4, 2013

Lack_of_sleepWashington, Sep 4: Lack of a good night's sleep can not only give you puffy eyes but also make you look old by increasing the wrinkles and fine lines on your face, a new study has found.

People also looked sadder when sleep-deprived than after normal sleep, and sadness was related to looking fatigued, scientists said.

Sleep deprivation affects facial features such as the eyes, mouth and skin, and these features function as cues of sleep loss to other people.

Researchers from the Karolinska Institute in Stockholm, Sweden, found that the faces of sleep-deprived individuals were perceived as having more hanging eyelids, redder eyes, more swollen eyes and darker circles under the eyes.

Sleep deprivation was also associated with paler skin, more wrinkles or fine lines, and more droopy corners of the mouth.

"Since faces contain a lot of information on which humans base their interactions with each other, how fatigued a person appears may affect how others behave toward them," said Tina

Sundelin, lead author and doctoral student in the department of psychology at Stockholm University in Stockholm, Sweden.

"This is relevant not only for private social interactions, but also official ones such as with health care professionals and in public safety," Sundelin said.

The study photographed 10 subjects on two separate occasions: after eight hours of normal sleep and after 31 hours of sleep deprivation.

Forty participants rated the 20 facial photographs with respect to 10 facial cues, fatigue and sadness.

According to the authors, face perception involves a specialised neuronal network and is one of the most developed visual perceptual skills in humans.

Facial appearance can affect judgements of attributes such as trustworthiness, aggressiveness and competence.

The study was published in the journal Sleep.

Washington D.C., May 5: Working from home has become the new normal ever since the outbreak of coronavirus and in today's time the work duties can be easily dealt with by means of mobile devices at home.

However, this easy use of technology, mobile devices for that matter, has the potential to blur the fine line between work and the other daily life routines.

But, contrary to the belief, a study at the University of Jyvaskyla reveals that the mixing of work and other daily life routines may have more benefits than previously assumed, and points to the importance of boundary-spanning communication.

A smartphone enables phone calls, email, and file transfers from the comfort of home. The study shows that there may be more effective ways to maximise the benefits of smartphone use, without diminishing employees' flexibility and the use of these technologies.

"People often forget to talk about positive effects, such as autonomy and freedom the employees gain when they have the flexibility to schedule their work," said Postdoctoral Researcher Ward van Zoonen from JYU, who with his colleagues examined the use of smartphones for work matters outside working hours.

The study paid special attention to the benefits of talking about domestic matters with the immediate supervisor outside the working hours given to an employee.

"This reduces the conflict between work and other life," van Zoonen said.

"If people in an organisation strive for more dialogue between employees' different life domains, it is possible to create a functional environment where people can talk about different matters."

The research findings show that when employees communicate across boundaries and talk at work about their life in other respects, they can receive new kinds of support and understanding from their immediate supervisor.

"This kind of communication creates a low threshold for contacting one's supervisor, which helps employees build a balance between the different domains of their lives and strengthens their organisational identification," said Professor Anu Sivunen describing the findings.

This means that tight working time restrictions to protect employees might not be beneficial after all, if they hinder reaching the positive results indicated in this research.

For the study, a survey was taken of 367 employees who were asked questions such as -- how much they talk about their work with their family, and how much they talk about their family with their immediate supervisor.

"Both supervisors and their employees answered the surveys, and the study actually focused on their mutual communication," Sivunen said.

"Usually people at workplaces are interested in how communication within the work community is succeeding. It is often forgotten how an immediate supervisor can take an employer's other life into account and thereby help the employee gain work-related benefits."

"Communication with one's immediate supervisor during flexible working hours, also on matters other than work, could ease the daily lives of many employees if they could share the possible challenges of their family life or free time with their supervisor in these settings," Sivunen added.

According to the study, such a practice could make the supervisor aware of the employee's situation as he/she works from home and the related impacts on their work performances.

The COVID-19 pandemic and the subsequent lockdown saw many people turning chefs overnight, but those who could not turned to online delivery of food. And not just any food, as per a new report, Indians "craved the most for Biryani" during the lockdown.

The "StatEATistics report: The Quarantine Edition" from food delivery platform Swiggy found that Indians ordered biryani over "5.5 lakh times" from their favourite restaurants.

The new normal might have opened a pandora's box of behavioral changes, but some old habits die hard like the love for Biryani, which took the top spot for overall orders. It was followed by butter naan and masala dosa at 3,35,185 and 3,31,423, respectively.

Biryani has topped the list of most ordered dishes for the fourth year in a row, the food delivery platform noted.

Indians didn't forget to indulge their sweet tooth in the uncertain months of lockdown. Their favourite comfort food during the lockdown period was the moist and decadent Choco Lava cake, ordered around 1,29,000 times.

"The humble Gulab Jamun (84,558) and chic Butterscotch Mousse cake (27,317) followed suit," said the report derived from Swiggy's order analysis in the past few months across cities that it is present in.

Also, as birthday parties moved to video calls, and virtual cake cutting sessions, according to the food delivery platform, it delivered nearly "1,20,000 cakes" to complete these celebrations.

According to the report, on average, "65,000 meal orders" were placed by 8 pm each day to make sure food arrived in time for dinner.

"It was the busiest hour for Swiggy delivery partners and restaurants. On average, they (customers) chose to tip Rs.23.65, with one particularly generous customer tipping Rs. 2500!," it added.

For those who only relied on home-made food during the quarantine, Swiggy delivered a whooping 323 million kgs of onions and 56 million kgs of bananas through its grocery section and hence ensured that its consumers were all stocked up.

That said, it also took care of the 'quick-fix meal' tribe -- consumers who resort to the evergreen college hacks of living on instant noodles.

"Around 3,50,000 packets of this ideal easy to cook meal were ordered during the lockdown," it said.

In all, Swiggy delivered 40 million orders across food, groceries, medicines and other household items during India's lockdowns. It also delivered over 73,000 bottles of sanitizers and hand wash along with 47,000 face masks as the definition of essentials' changed during these uncertain times.

Being overweight or obese is now recognised as a serious cause of ill health and disability. There is a significant positive association between orthopaedic disorders and the level of obesity causing pain, deformity and difficulty in walking.

Excess body weight accumulation increases pressure on joints, particularly the hips, knees and ankles.

Here are a few type of  arthritis:

Osteoarthritis

It is a condition of damage/ wear and tear of the joint lining or cartilage. Obesity triggers this by loading excessive weight on the weight bearing joints like the knee and the hip. 

Knee Osteoarthritis

This is the most common arthritis especially in the Indian subcontinent.

While walking, an individual exerts 3 to 6 times pressure that of the body weight on the weight-bearing knee joint, which means in an obese with excess body weight, larger forces are exerted, which lead to higher risk of deterioration of cartilage.

In addition, there are excessive fat tissues that produce hormones and other factors that affect the joint cartilage metabolism and cause inflammation of the joints giving rise to joint pathology.  Leptin is one of the hormones causing knee osteoarthritis. 

Hip osteoarthritis

The force exerted across the hip is 3 times that of body weight. Hip osteoarthritis is caused by factors such as joint injury, increasing age and being overweight.    

Hand osteoarthritis

The observation that obese individual has a higher risk in having hand osteoarthritis has led to a hypothesis that the metabolic effect produced by fat tissue is the underlying factor. 

Osteoporosis

It is a progressive bone condition of decrease in bone mass and density (Bone Mineral Density or BMD) which can lead to an increased risk of fracture. Recent research suggests that obesity may accelerate bone loss. It is the amount of muscle mass which is seen in an active person, which accounts for bone strengthening effects and not due to the fat seen in a heavy person.

Low back pain

Low back pain from degenerative disc disease of the lumbar spine is one of the most disabling conditions in the community and overweight and obesity have the strongest association with seeking care for low back pain.

Managing Hip and Knee Osteoarthritis

Life style changes

If one is overweight, try to lose weight by doing more physical activity and eating a healthier diet. Regular exercise keeps you active and mobile and builds up muscle, thereby strengthening the joints and can improve symptoms. 

Pain Killers

Painkillers help with pain and stiffness for short term. They don’t affect the arthritis itself and won’t repair the damage to your joint. Creams and gels can be applied directly onto painful joints.

Nutritional Supplements

Glucosamine and chondroitin are nutritional supplements. Animal studies have found that glucosamine can both delay the breakdown of and repair damaged cartilage. However, there is insufficient evidence to support the use of glucosamine in humans and one can expect only a mild-to-moderate reduction in pain

Joint injections

If pain from osteoarthritis is severe joint steroid injections are injected into the joints that can reduces swelling and pain. The injections can start working within a day or so and may improve pain for several weeks or months. 

Hyaluronic acid injections, which help to lubricate your knee joint also give short term relief. In early stages. Stem cell treatment or cartilage regeneration procedures are being tried in young people with small defects, however it is still experimental and lacks long term evidence.

Surgery

May be recommended if you have severe pain or mobility problems.

Arthroscopy

If one has frequent painful locking/stiffening episodes especially in the knee joint, an operation to wash out loose fragments of bone and other tissue as joint can be performed by a minimally invasive key hole procedure called Arthroscopy.

Arthrodesis

If hip or knee replacement is not suitable, especially in young people who do heavy manual work, one can consider an operation known as an arthrodesis, which fuses your joint in a permanent position. This means that your joint will be stronger and much less painful, although you will no longer be able to move it.

Osteotomy

In young, active people in whom a knee joint replacement would fail due to excessive use one can consider an operation called an osteotomy. This involves adding or removing a small section of bone either above or below your knee joint.  This helps realign your knee so your weight is no longer focused on the damaged part of your knee. An osteotomy can relieve your symptoms of osteoarthritis, although you may still need knee replacement surgery eventually as you grow old

Joint replacement surgery

Joint replacement therapy is most commonly carried out to replace hip and knee joints. It involves replacing a damaged, worn or diseased joint with an artificial joint made of special plastics and metal.

For most people, a replacement hip or knee will last for at least 20 years, especially if it is cared for properly and not put under too much strain.
