The world in the 21st century is one of rapid expansion. The world’s population has ballooned to over 7 billion people. It is estimated that there over a billion cars now being driven worldwide and 6 billion cell phones in the hands of people from Manhattan to Mali. This expansion has led to a host of unsurprising yet concerning effects and consequences. Environmental degradation now affects every corner of the globe. More and more people, mostly in developing nations, are lacking access to clean drinking water. Respiratory illnesses are becoming more commonplace due to poor air quality in parts of the globe. These are just a couple of the growing concerns related to contemporary issues of pollution.
While these problems are worldwide and do not recognize borders, some of the most dire situations are found in the world’s cities. The 21st century world is an urban one. Current projections estimate that the percentage of the earth’s population living in urban areas will be at 70% in 2050. The effects of urbanization can be both positive and negative. The concentration of human populations in urban areas can create a situation where rural areas are subject to less strain and more open to wildlife and pristine wilderness. However, if this increase is not done intelligently and sustainably, the negatives will outweigh the positives. Increased fossil fuel consumption, further deterioration of forests, pollution of fresh water sources and exponential industrial growth are just a few important environmental concerns. The following are a few of the most polluted cities in the world: Read more…

Healthy eating is the most important aspect of healthy life. To eat healthy it is important to make healthy meal plan and adhere to it as closely as possible. While making healthy meal plan, what is required is to have provision for all the nutrients we need for healthy living, such as macronutrients (carbohydrates, fats, proteins etc.) and micronutrients (such as vitamins and minerals) and trace minerals such as boron, selenium, copper, zinc etc.
Healthy meal plan for carbohydrates, fats and proteins:
Most of us have some staple food. For some staple food may be rice, for some wheat, maize or some other grain, We can get carbohydrates we need from the staple food we eat and for that planning is not required. Every gram of carbohydrates supplies four Kcal (kilocalorie) of energy. Carbohydrates supply majority of or calorie needs (approximately 65%) for humans.
Planning for adequate and right kind of fat require some planning. We must avoid animal fats (such as beef, pork fats, because they are rich in cholesterol) and eat more plant based fats and fish oil, which are rich in unsaturated fatty acids and good for reducing cholesterol level. Every gram fats supplies nine kilocalories of energy and fats should contribute to not more than 20% of total calorie intake for healthy life. For healthy meal plan add nuts (walnut, groundnut, cashew nut etc.) and fish (sea fish as well as fresh water fish) and vegetable oils such as olive oil. Read more…

Your teeth are meant to last for a lifetime, however a little care can help them remain attractive and strong. Orthodontic care is directed towards creating a highly improved self-esteem.
Here’s a list of top 5 tips to guide you when you set out for an orthodontic treatment:

Few people have the perfect set of teeth. Most people have misaligned teeth. This will require corrective braces or dental surgery. A dentist can give you a general idea on whether you require braces or surgery. If you are uncertain, you must see a dental specialist as soon as possible, for quick corrective measures.
2. Delays can escalate into other trouble areas – If an orthodontic service is required but not undertaken for whatever reasons like finances or lack of insurance etc, it could lead to cosmetic and physical problems, later in life. Extreme misalignment can lead to uneven placement of your teeth. This will further lead to aesthetic issues of the face, speech problems and compromised chewing.

The subject also covers the overall effect of neuro-musculoskeletal disorders on overall general health of an individual. At present chiropractic practice, is available in more than 100 countries, although most chiropractic practitioners are fond in North America (especially in United States and Canada), Europe (in UK and other countries) and Australia.

Nursing is an incredibly fulfilling job, but it does come with a number of occupational hazards. It’s incredibly important that you take good care of yourself in the same way that you would your patients – if you’re not able to work, you won’t be able to help them! Here are 5 common nursing injuries and how to avoid them.
Nicks and Cuts
Nicks and cuts are incredibly common for a nurse, and even minor cuts like paper cuts can develop into something more serious if they get infected, so it’s really important that you try to minimise your risk of getting them. Because nurses handle sharps everyday, it can sometimes result in automatic handling – meaning that you’re more likely to get cut. Always be aware of what you’re carrying and be very respectful of knives and other sharps at all times. If you do get cut, wash the area well and apply a bandage. Look after the area, change the bandage regularly and if you need to, apply an antiseptic.
It’s also surprisingly common for nurses to get burns while working – sterilisers can get very hot, while many nurses are known to rush about with a mugful of extremely hot coffee, and with just one slip you can burn yourself quite severely. Be careful when handling hot drinks and hot liquids, as well as foods, and when using sterilising equipment and autoclaves, take real care! If you do get a burn, rinse the area with cold water, apply ice and antiseptic if needed and wrap with a bandage. Seek medical attention if the burn is particularly severe. Read more…

Electronic cigarette (also known as e-cigarette) is an electronic inhaler that uses vaporized liquid in aerosol mist form, which simulate tobacco cigarette. The liquid used in electronic cigarettes include propylene glycol, vegetable glycerin, polyethelyn glycol-400 etc. All these (propylene glycol, vegetable glycerin, polyethelyn glycol-400) are used as food additive and as additive in tooth pastes as well as in inhalers used for treatment of asthma. Electronic cigarettes were marketed as a tool for quitting smoking, but currently in many countries it is not used as tool for quitting smoking.
Electronic cigarette and conventional cigarettes differ in many ways. Most e-cigarettes look similar to conventional tobacco cigarettes, in size and shape, but some do not have any similarity at all. Electronic cigarettes do not contain any tobacco product, it contain a liquid instead. The liquid may contain nicotine or may not contain nicotine. In most electronic cigarettes the nicotine content approximately same as that of a conventional tobacco cigarette. In some electronic cigarettes the quantity of nicotine released can be controlled by the user.
Health concerns of electronic cigarettes:
Electronic cigarettes use nicotine in the liquid, which raises health concern, as there are not many clinical studies done on this subject to find out the effectiveness and the risk involve. The supporters and manufacturers of electronic cigarette claim that it gives the effect of smoking (due to presence of nicotine) to smokers, but it is devoid of harmful substances that cause lung cancer and other deleterious health problems if one smoke conventional tobacco cigarettes.
