Lack of Sleep and Obesity

Lack of Sleep and Obesity



 
What is the connection between lack of sleep and obesity?

The recommended amount of sleep per night is 7 to 9 hours; however, most Americans average somewhere around six hours. Researchers found that the further away one is from getting the recommended hours of sleep, the higher their risk of obesity is.

What is the scientific basis of sleep debt leading to obesity?

If one is lacking the optimal amount of sleep, their leptin levels drop. Leptin is a blood protein that suppresses appetite and affects how the brain registers when the body is full. Also, sleep deprivation raises levels of grehlin, which is a substance that increases one's urge to eat. In short, if you sleep less number of hours, your leptin level falls, and grehlin goes up, resulting in overeating and weight gain.

What is the result of obesity on sleep loss?

Fat accumulation in the throat and neck cause obstruction of airways during sleep leading to poor oxygenation of the lungs. This causes pathological snoring called sleep apnea. You wake up several hundred times during the night. You have day time drowsiness, and again another night of disturbed sleep. This condition is called obstructive sleep apnea.


If so, the obstructive sleep apnea leads to more sleep debts, more stress, and more leptin and grehlin problems, more weight gain in a vicious cycle.

So what is the solution?

1. If you snore a lot, get yourself checked for obstructive sleep apnea.

2. Work on weight loss.

3. Control stress and maintain better sleep hygiene

What are the true costs of building

and owning an in-ground swimming pool?



 
Have you ever wondered how much it would cost to install a beautiful in-ground pool in your backyard? Then once you have the pool, what would be your on-going costs to keep it maintained?

This article will discuss, and show, the true costs associated with building and maintaining an in-ground pool. Due to the many details being discussed, the article is divided up into 4 parts. Part 1 is below. The other 3 parts can be found at the web address given below.

If you would like to know what would be your cost, per month, to own and maintain a pool, please read this very informative article to its end.

GENERAL POOL COSTS
===
The cost of installing a new in-ground swimming pool is going to vary widely. You could have a decent size pool installed for as little as $10-12,000, or one that could reach towards 6 figures and upwards, depending on whether you want a gold-plated pool or not. Actually, I don't think gold-plated pools exist but you get the idea about the expense. We obviously we will focus on the lower end.

TYPES OF POOLS
===
Now on to the details, the first factor that will determine pool cost is the type of pool. Your choice will probably fall into one of the three following types:
1.) steel-walled, vinyl lined pool
2.) fiberglass pool
3.) cement (or unite) pool.

OTHER POOL FACTORS TO CONSIDER
===
The second factor is the size and shape. It should be obvious that the larger pools are going to cost more, but fancy shapes will also be expensive. You could potentially get an 18 ft x 36 ft rectangle for a cost similar to that of a 16 ft x 32 ft kidney shaped pool. You get the idea
 



From here on, we'll deal exclusively with the cost of a vinyl lined pool, but please keep in mind, that fiberglass and gunite pools should be competitively priced depending on where you live. In fact, in some markets, there are so many pool builders that the gunite pools are cheaper than the vinyl ones.

Furthermore, some environments require a gunite pool. If all this is true, then why are we talking about a vinyl pool? Well, simply because the company I worked for only installed vinyl pools, and the pool that was installed at my home is a vinyl pool. I think we'll all be better off if I go with what I know best.

THE MAJOR COST OF POOL INSTALLATION
===
The first thing to remember is that one of the major costs of building a pool is labor. In fact, I heard once that materials for gunite pools are actually cheaper than vinyl-lined pools because the only material is basically cement mixture, rebar and piping. But this type of pool is quite labor intensive. On the other hand, the kit for a vinyl pool includes things that cost a bit more, like the steel walls, framing, steps and the vinyl liner, but many pool builders prefer to install these vinyl pools because they are much quicker and easier to install.

For more information on the actual costs associated with buying, installing, filling, and maintaining a new pool, please see the web site listed below. This article will end with your approximate total monthly outlay to own a pool.
