Now there are three types of clocks, which are conducting the affairs of our day-to-day life. These three clocks are 1.) Local clock 2) Global clock and 3) Biological clock. Local clock is clock which is dependent over the motion of sun in the area where we are living. Global clock is the clock, which never stops, and every company or organization working 24×7 is actually working under a global. Third clock is very important; this is our personal biological clock. We need to sleep in order to rest our body and brain and this is the third clock.
First two cloaks are mechanical clocks, but third clock belongs to a human body and it is the most difficult task to handle this clock. Now they are working under a kind of rotation policy where they change the shifts of employees every now and then. It is a herculean task to change this sleep cycle of human body. Sometimes it can take more than day two days and during this period the person has no other option but to stay in that haze of daytime drowsiness or excessive sleepiness during the working hours. If it is happening because of the fact that a person is changing his shifts too frequently then we can also name it as shift related sleep disorder as well.
This shift related sleep disorder and the probable attacks of daytime drowsiness are curable. Here all you need is to take this amazing pill, which is Provigil. This pill is an alertness promoter. They were using it for the same purpose with the patients of sleep apnea and narcolepsy as well. Provigil or Modafinil has this power to stimulate the tired neurotransmitters, which are present in the brain, and this is how it gives you an additional six more active hours and after it you retire for the sleep. This is an easy and tested way to take care of your shift related sleep disorder and get you adjusted with the global clock or any other clock for that matter.

In the last few years, they have witnessed a remarkable growth in the number of patients, which are suffering from sleep apnea. A big chunk of people is living a hazardous lifestyle, which can subject them to sleep apnea very frequently. Simple things like Smoking and obesity can also be a potential reason behind sleep apnea or obstructive sleep apnea.
Sleep apnea is a disease, which can envelop a person at any given age, and this is why they were not connecting it with any type of vices at all. On the contrary, they were treating it as a curse of God bestowed on them. Let us admit the fact that we are still short of effective cures against this disease. We can manage it but this is not a permanent solution. This is only a struggle for a patient whose life goes for a toss.
There are two types of sleep apnea. First is OSA or obstructive sleep apnea where a person gasps for breath when he is sleeping and often wakes up because he is feeling short of breath. This is the most common type of sleep apnea. Second is central sleep apnea, this disease attacks on the central nervous system of a person and he loses his cognitive abilities. He fails to decipher the signals of the brain and this makes him unable to perform the daily rituals, which are necessary for the life. Based on these two types they have also found a third type of Apnea, which is mixed apnea. In this case, a person may feel the signs of both types of apnea.
In the latest researches, they figured out three major risk factors. First factor is age. The chances increase many folds when a person crosses the age of 65. Rest of the two factors is under your control, they are obesity and smoking. OSA and CSA have added two more deadly chapters in the medical history of regular smokers and people who are careless about obesity. This is high time to control these two things and save you from a probable hazard.

You may have heard about cat’s nap and lion’s sleep a lot. Cats love  to sleep in between their hardworking missions. Lions love to sleep to point until they go for the next hunt. Now here we are talking about two very agile and focused animals from the wild kingdom. They understand the importance of the sleep to the core.

However, humans are forgetting the age-old wisdom that has been imparted on them. They are designing their working routines and routines in such a fashion where they do not have enough time to sleep. Here we are talking about the regular quota of sleep and not the siesta, which is very important for a person.

In the terms of literature siesta is an afternoon nap, which a person takes right after having lunch. Let us travel back to our roots, our villages. Masons and the farmers working in the fields never forget to enjoy this siesta right after the lunch; it reenergizes them for the work. This same siesta is very good for your brain, unfortunately, our office culture does not have any scope for this siesta and this is why some problems like day time drowsiness and excessive sleepiness during the day are surmounting their way in the life of these people.
These two things are more than sufficient to kill your performance during the second half of the day. Here you can take the services of an ideal alertness promoter drug. This drug is Modafinil and it is widely available on internet sources. You need to take this drug right before the probable attack of day time drowsiness and once it will seep in then it will settle down everything by stimulating your brain and bring your focus back in the work. As an aftermath of the consumption of this drug, you will retire to sleep after finishing all the important tasks of the day.
