AsthmaA chronic inflammatory disease, asthma occurs when lungs do not get adequate amount of oxygen. The condition affects the airways that carry oxygen to the lungs. Inflammation makes the airways sensitive to irritations and makes you susceptible to an allergic reaction. These symptoms usually worsen during nights and in the morning time. Asthma mainly develops during childhood and aggravates with age.

Symptoms and Causes

There is no one cause of asthma; several factors may contribute to asthma symptoms.

  • Air pollution
  • Allergies from house dust
  • Sudden change in temperature
  • Food allergies
  • Irregular menstrual periods in case of some women

Some of the most common symptoms of asthma include:

  • Tightness in your chest
  • Short breath or breathlessness
  • Coughing and wheezing regularly
  • Problems in exercising


Scientists are of the opinion that vitamin D may help reduce production of a chemical that makes symptoms of the condition worse. Vitamin D significantly reduce production of the natural chemical that is helpful in defending itself against infection, showing its potential as an effective treatment for asthma. Researchers at King's College London have found vitamin D extremely useful in reducing the symptoms of asthma sufferers, helping them to breathe easy.
