Insufficient Sleep Can Cause Obesity

A recent study from the University of Leeds

A recent study from the University of Leeds showed that people who were sleeping on average around six hours a night had a waist measurement that was 3cm greater than individuals who were getting nine hours of sleep a night. And shorter sleepers were heavier too. The results strengthen the evidence that insufficient sleep could contribute to the development of metabolic diseases such as diabetes.

Previous studies have shown that poor quality sleep and lack of sleep contributes to obesity through poor dietary choices - namely the types of food people consume and their portion sizes. In this study, the researchers found a new metabolic link relating to sleep - shorter sleep was linked to reduced levels of HDL cholesterol in the participants’ blood – another factor that can cause health problems. HDL cholesterol is ‘good’ cholesterol that helps remove ‘bad’ fat from the circulation. In doing so, high HDL cholesterol levels protect against conditions such as heart disease.

Dr Hardie said: “Because we found that adults who reported sleeping less than their peers were more likely to be overweight or obese, our findings highlight the importance of getting enough sleep.

"How much sleep we need differs between people, but the current consensus is that seven to nine hours is best for most adults.”

Sleep Disorder Prevention Tips for Night Shift Workers

All of us have an inbuilt biological system within the body that keeps us awake and alert during the daytime. Long-term deviation from this natural cycle can very easily lead to different types of sleep disorders.

If you have ever tried to sleep during the day, you must have experienced that it is extremely difficult to have seven or eight hours of uninterrupted sleep. It may seem almost impossible to fall and remain asleep with so much of noise and other hindrances around. Even when you manage to find a quiet and cozy corner, personal relationships and family responsibilities can very easily play spoilsport.

People with a routine time for sleep and waking up regulate their biological hormones to initiate and maintain sleep well. When this normal schedule is switched too frequently, the body often fails to adapt to the changed pattern. Sleep disorder is common with many shift workers because their work and rest schedule keeps changing all the time and the body sleep rhythm cannot keep up with the changes. On average, it has been found that people working in night shifts have a sleep deficit of two hours compared to an average adult. This deficit exposes them to the risk of several long term health problems.

Finding the correct shift pattern for the body clock is extremely important for shift workers. If your job necessarily demands working in shifts, it is advisable to stick to a particular routine for at least two consecutive weeks. Always remember that working in rotating shifts is comparable to a never ending jet lag. Therefore, it really helps to have a relatively longer adjustment period between the different types of shifts.

Working in shifts is often associated with putting in extended working hours. If you end up working for more than eight hours, you are at a higher level of risk. Also, please remember that all individuals are different, and some people may find it relatively easier to adapt to erratic shift timings. You must be extremely careful about ensuring adequate sleep time, if your body finds it difficult to adjust to your shift pattern. In case of a serious sleep disorder, you may even want to consider working on a regular shift during the daytime.

If you are not able to change your shift time, here are a few things you can do to optimize your night shift schedule

  • Before starting your night shift schedule, gradually taper your sleep-wake cycle towards your upcoming schedule
  • Always take a nap before the start of the night shift
  • When you have the same shift for a few days, promote the natural cycles of the body by taking meals at the same time every day.
  • Avoid caffeinated drinks in the later part of the shift because it may reduce your sleep hours after the end of the shift.
  • Use dark drapes or curtains at home to ensure adequate sleep and no light disturbance.
  • People living in a noisy environment may also use earplugs.
  • Try to remain fit by regular exercising, especially in the first few hours after waking
  • Try to get sunlight or outdoor light exposure soon after waking up and limit light exposure (e.g. with sunglasses) in the few hours before you want to sleep.

Tips to Fix Your Snoring Problem


Before finding a way to control your snoring problem, it is important to understand why we snore. The muscles in our throat  relax during sleep. Turbulent airflow then occurs through a narrowed airway causing vibration and shaking of the uvula and soft palate tissues to cause snoring.

Snoring is often associated with obstructive sleep apnoea, a breathing disorder in sleep where the airway closes off completely and the person stops breathing. This is turn is associated with a number of health conditions such as stroke and heart disease, high blood pressure, anxiety, depression, low self esteem, and reduced libido. Work place or driving accidents can occur due to daytime sleepiness and lack of attention.  

Do you suffer from a snoring problem? Have you ever been teased by your family members and friends for your loud snoring during sleep? Well, you are certainly not alone. Nowadays, a high percentage of adults as well as minors are affected by this problem. There is no denying the fact that snoring can disturb others. However, snoring can be a clue to a serious health concern that demands attention. People with a snoring problem are more likely to be irritable and tired because it can also be associated with impacts on their own sleep quality. Moreover, the noise caused by snoring affects their sleeping partners. If left unattended, snoring can be a constant source of frustration and tension between the couples.

Some lifestyle factors exacerbate snoring and obstructive sleep apnoea. Being overweight, evening alcohol, smoking, and sleep deprivation are some of these factors.

Snoring and obstructive sleep apnea are treatable. Simple early lifestyle changes include:

  • Losing weight: even 10%  weight loss can have a big effect.
  • Changing sleeping position: in some cases, sleeping on your side will reduce snoring and obstructive sleep apnoea.
  • Stopping  smoking
  • Avoiding alcohol consumption before bedtime
  • Avoiding heavy meals at night

Often snoring is a symptom of obstructive sleep apnea (OSA). Clues to obstructive sleep apnoea include breathing pauses in sleep, gasping episodes overnight, daytime tiredness and sleepiness. OSA needs to be investigated and managed medically. You should visit your GP and be referred to a Sleep Specialist for further testing and treatment advice.
