Reduced sleep time may be a source of weight gain!!!

One of my best friends is engaged from few months. Just like all other couples, they too are often spending lots of time chit chatting at night time. Both have to wake up early in the morning to start their busy daily routines and have to travel quite a long distance for their jobs. In spite of this, he is able to find time for maintaining good health and is concentrating on building  muscle mass and improving physical fitness as his marriage date is nearing. And as we all know your looks are most important on the occasion of your marriage...so one will surely be health conscious at this moment...

Today morning I got a call from him. While we were having casual talk, he informed me that he went through an article on internet which says,

"Reduced sleep time may be a source of weight gain!!!"

 I also became curious and went through it. I found it interesting and it was really worth reading...

So thought of sharing it with u friends...here are some glimpses of the same...

Main finding of the article was:  loss of sleep causes weight gain and loss of muscle mass. Possible mechanism explained for this may be sleep loss is associated with down-regulation of the glucose metabolism pathway in skeletal muscle, whereas this pathway instead is up-regulated in subcutaneous adipose tissue. It is published in science advances. A study was conducted among healthy participants who had at least 7 to 9 hours of good quality sleep per night.

Important facts due to acute sleep deprivation:

  • Increased levels of proteins responsible for production of fat cells.
  • Changes in gene profile favoring fat production and deposition
  • Lower skeletal muscle mass
  • Increased levels of the catabolic hormone cortisol.
  • Reduced sex hormone i.e. testosterone levels

What are the symptoms that you feel that I am not getting enough sleep?

Sleep deprivation, either from regularly not allowing enough time for sleep or due to a physical or mental problem that prevents restful sleep, produces noticeable symptoms, including the following:

  1. a) Feeling of sleepiness during the day or at work.
  2. b) Very brief episodes of sleep i.e. microsleeps
  3. c) Routinely falling asleep within only 5 minutes of lying down in bed for the night

In modern days, sleep deprivation or changed pattern of sleep is often seen in people working in shifts, call centre and frequent travelers. Various researches have showed association of sleep disturbances with health issues and economic impact in the past.

Sleep loss does have an impact not only on one’s health but also on economic welfare...

  1. A) Impact on health:
  • Obesity in adults and children
  • Diabetes and impaired glucose tolerance
  • Cardiovascular disease and hypertension
  • Anxiety symptoms
  • Depressed mood
  • Smoking,
  • Excessive alcohol and sugary drink consumption,
  • Lack of physical activity,
  • Stress at work, shift work/irregular working hours, and
  • Long commuting.
  • Higher mortality risk - An individual that sleeps on average less than six hours per night has a 13 per cent higher mortality risk than someone sleeping between seven and nine hours. An individual sleeping between six to seven hours per day still has a seven per cent higher mortality risk.
  1. B) Economic impact:
  •  Financial losses due to lack of sleep are estimated to be around approximately U.S. ( up to $411 billion a year), Japan (up to $138 billion a year), Germany (up to $60   billion) and the UK (up to $50 billion)
  •  Small changes to sleep duration could have a big impact on the economy. For example, if individuals that slept
  •  Sleep deprivation is linked to lower productivity at work, which results in a significant amount of working days being lost each year. On an annual basis, the U.S. loses  an equivalent of around 1.2 million working
