Nose Bleeding

Causes of Nose Bleeding most commonly are, trauma to the nose. Trauma to the outside of the nose, such as a blow to the face, or trauma inside the nose, such as nose picking or repeated irritation from a cold, can cause a nosebleed.
Less commonly, an underlying disease process, such as an inability of the blood to clot, may contribute to the bleeding. Abnormal blood vessels or cancers in the nose are rare causes of nosebleeds. High blood pressure may also contribute to bleeding but is almost never the only reason for a nosebleed.

Blood Transfusion

A blood transfusion is the transfer of blood or blood products from one person (donor) into another person's bloodstream (recipient). This is usually done as a lifesaving maneuver to replace blood cells or blood products lost through severe bleeding, during surgery when blood loss occurs or to increase the blood count in an anemic patient.

Blood transfusions can be a life saving measure. Volunteer donor blood usually is readily available, and when properly tested has a low incidence of adverse events. The likelihood of contracting infections from a blood transfusion is very low. Blood conserving techniques are an important aspect of limiting transfusion requirements. Blood banks are responsible for collecting, testing and storing blood. People with Type O, negative blood are considered universal donors as it is safe to transfuse to nearly everyone.

Effects of Air Pollution

  • The effects of Air pollution are very alarming, they create several respiratory and heart
    conditions along with Cancer, among other threats to the body. Several millions are known to have died due to direct or indirect effects of Air pollution. Children in areas exposed to air pollutants are said to commonly suffer from pneumonia and asthma.
  • Another direct effect is the immediate alterations that the world is witnessing due to Global warming. With increased temperatures world wide, increase in sea levels and melting of ice from colder regions and icebergs, displacement and loss of habitat have already signaled an impending disaster.
  • Harmful gases like nitrogen oxides and sulfur oxides are released into the atmosphere during the burning of fossil fuels. When it rains, the water droplets combines with these air pollutants, becomes acidic and then falls on the ground in the form of acid rain. Acid rain can cause great damage to human, animals and crops.
  • Just like humans, animals also face some devastating affects of air pollution. Toxic chemicals present in the air can force wildlife species to move to new place and change their habitat. The toxic pollutants deposit over the surface of the water and can also affect sea animals.
  • Ozone exists in earth’s stratosphere and is responsible for protecting humans from harmful ultraviolet (UV) rays. Earth’s ozone layer is depleting due to Air pollution. As ozone layer will go thin, it will emit harmful rays back on earth and can cause skin and eye related problems. UV rays also have the capability to affect crops.

Blue Fingertips

Our fingers, toes and ears are the most vulnerable to temperatures. When we are exposed to the cold,

Symptoms of Raynaud’s can include tingling and numbness in the fingers and toes, whitening of the fingers and the blue discolouration.
our bodies conserve heat by decreasing blood flow to our hands and feet. In general, this is short-lived and will reverse quickly – unless you have Raynaud’s.
