A cough is basically a reflex action so the airways can be cleared of phlegm, mucus and other irritants like dust and smoke. An inflammation of the upper respiratory tract due to a virus could also cause a cough.

Coughing can be symptomatic of many conditions including bronchitis, asthma, the common cold, flu, whooping cough or smoking. There are even some prescribed medicines that can cause coughing such as ACE-inhibitors which are used to treat heart failure.

Sometimes a cough can be a symptom of an underlying serious medical condition such as heart failure, lung cancer, tuberculosis, pneumonia or a pulmonary embolism (which is a clot on the lung). Coughs that have been caused by things like flu or the common cold normally disappear after a few days, but coughs that have been caused by an infection of the lung, such as bronchitis, could persist for several weeks, even after the infection has cleared up and this is due to the inflammation of the airways which usually take a while to clear up.

Cough Mechanism and Receptors

If someone has been suffering from a cough for more than a couple of weeks after having a viral infection, they should go to their doctor for medical advice.

Restless legs can affect movement and sleep.  A person with restless legs has an uncontrollable urge to move their legs; the condition is more common in women and it is also known to affect people more as they age.

The severity of symptoms can vary from person to person.  Symptoms can be quite mild or very debilitating although it is not life threatening. These can include an urge to move the legs, disturbed sleep or trouble getting to sleep, uncontrolled jerking of the legs or unpleasant feelings deep in the legs.

Symptoms usually occur at night when the body is at rest.  People have described feelings like prickling itching or tingling which can be relieved momentarily by movement.

The two types of restless legs syndrome are primary restless syndrome and secondary restless leg syndrome.  Primary restless legs syndrome can begin at any age but usually occurs in early adulthood.  It occurs naturally and is usually mild to begin with but symptoms can increase and become more severe in later life.

Secondary restless legs syndrome is normally a result of another condition such as kidney failure, alcoholism, pregnancy or iron deficiency anemia.  Antidepressants and antipsychotics have also been known to worsen the symptoms.

Restless Legs

Lifestyle changes can help with mild cases of restless legs syndrome but for more severe cases this can be treated with a mixture of lifestyle changes and medication. Lifestyle changes can include avoiding caffeine, tobacco and alcohol, increasing exercise early in the day, creating a regular sleeping pattern and avoiding any medication which can increase symptoms. Taking a hot bath in the evening can also help to relieve symptoms as can stretching the limbs.

The common cold can be described as an infection of the higher reaches of the respiratory tract, or in other words the throat, the nasal passages and the nose. It is interesting to note that there are over two hundred different virus’ that can presently cause the common cold, but the main culprit in adults is the rhinoviruses, of which there are a hundred different strains and are classified as nose virus’.

When an individual becomes affected by a cold, the symptoms usually show up around two days later and these include a sore throat, a runny nose and sneezing. Later symptoms can consist of watery eyes, headache, muscle aches, stuffed nose, and a general feeling of being unwell. The symptoms of a cold can last anywhere from two to seven days but in some cases may even last up to two weeks.

Common Cold

People who have a common cold may find that is accompanied by bronchitis, laryngitis, an ear infection or with those who suffer from asthma, a worsening of the condition. Common cold infections are so prevalent that it is estimated that an adult will suffer between two and five colds each year. Because of this, the condition is the leading cause of people missing work days through illness.

Contrary to belief, colds are actually not very contagious when compared to other infections. Prolonged and close contact is required for the virus to spread and it must get into the nose for there to be infection.
