Research into issues

As I was unsure upon which issue to tackle research was conducted. This can be seen below. 


Natural disaster 


Natural disaster- a natural event such as a flood, earthquake, or hurricane that causes great damage or loss of life.


As well as being dangerous to humans, these events shape our planet and affect where and how we live. Volcanoes are thought to have played an important role in the emergence of life. They enrich soils, making the land around them good places to grow crops. Earthquakes signal the movement of Earth's tectonic plates, which build mountains(including volcanoes). Fault lines are often rich inminerals – for example, gold is found along the San Andreas Fault in California.


How do natural disasters occur?

In order to gather a greater understanding upon how these events occur, online video were watched in order to demonstrate this clearly to myself. This allowed for myself to gain a greater knowledge upon why the life changing events occur. 


Earthquakes



Information I gained from this: 
  • The earth is made up from tectonic plates, where the plates meet this is called fault lines. Fault lines are where earthquakes occur.
  • Pressure from other plates causes a plate to slip, causing mass energy. 
  • The power of an earthquake is measured upon the Richter scale.


Floods 




  • One of the most common natural disaster
  • 15cm of waters to knock a human, 60cm can move a car
  • floods occur when water has no where to go
  • Floods spread disease
  • Disrupt water supplies


Tsunamis




  • Under sea earthquakes can displace a huge amount of water
  •  The displaced water is pushed out
  • Same speed as a plane 
  • Some measure up to 30m high
  • Nations across the specific are most likely to have one 
  • Warnings usually only come hours before 
  • Water born illnesses. 


Hurricanes, Typhoons and Cyclones




  • All the same just in different oceans 

  • The warm, moist air over the ocean rises upward from near the surface. Because this air moves up and away from the surface, there is less air left near the surface. Another way to say the same thing is that the warm air rises, causing an area of lower air pressure below.Air from surrounding areas with higher air pressure pushes in to the low pressure area. Then that "new" air becomes warm and moist and rises, too. As the warm air continues to rise, the surrounding air swirls in to take its place. As the warmed, moist air rises and cools off, the water in the air forms clouds. The whole system of clouds and wind spins and grows, fed by the ocean's heat and water evaporating from the surface.
  • Usually occur in tropical regions



Mental Illness 




a condition which causes serious disorder in a person's behaviour or thinking.

A few forms of mental illness:
  • Anxiety & Panic Disorders.
  • Bipolar Disorder.
  • Depression.
  • Eating Disorders.
  • Schizophrenia.
  • Substance Abuse & Addiction.
  • News & Features.
  • Find a Psychiatrist.

As every mental illness is different I would have to focus directly upon one specific area. For this task I decided to focus upon the number one reason individuals have time off work, depression. 



Depression is a common mental disorder that causes people to experience depressed mood, loss of interest or pleasure, feelings of guilt or low self-worth, disturbed sleep or appetite, low energy, and poor concentration.

Depression is different from feeling down or sad. Unhappiness is something which everyone feels at one time or another, usually due to a particular cause. A person experiencing depression will experience intense emotions of anxiety, hopelessness, negativity and helplessness, and the feelings stay with them instead of going away.

Depression can happen to anyone. Many successful and famous people who seem to have everything going for them battle with this problem. Depression also affects people of every age.

Half of the people who have depression will only experience it once but for the other half it will happen again. The length of time that it takes to recover ranges from around six months to a year or more.

Living with depression is difficult for those who suffer from it and for their family, friends, and colleagues. It can be difficult to know if you are depressed and what you can do about it.


Signs
  • Tiredness and loss of energy.
  • Sadness that doesn’t go away. 
  • Loss of self-confidence and self-esteem. 
  • Difficulty concentrating. 
  • Not being able to enjoy things that are usually pleasurable or interesting. 
  • Feeling anxious all the time. 
  • Avoiding other people, sometimes even your close friends. 
  • Feelings of helplessness and hopelessness. 
  • Sleeping problems - difficulties in getting off to sleep or waking up much earlier than usual.
  • Very strong feelings of guilt or worthlessness. 
  • Finding it hard to function at work/college/school. 
  • Loss of appetite. 
  • Loss of sex drive and/or sexual problems. 
  • Physical aches and pains. 
  • Thinking about suicide and death. 
  • Self-harm

Cause



Depression can happen suddenly as a result of physical illness, experiences dating back to childhood, unemployment, bereavement, family problems or other life-changing events.

Examples of chronic illnesses linked to depression include heart disease, back pain and cancer. Pituitary damage, a treatable condition which frequently follows head injuries, may also lead to depression.

Sometimes, there may be no clear reason for your depression but, whatever the original cause, identifying what may affect how you feel and the things that are likely to trigger depression is an important first step.


Forms 


Mild depression

Depression is described as mild when it has a limited negative effect on your daily life. For example, you may have difficulty concentrating at work or motivating yourself to do the things you normally enjoy.
Major depression

Major depression interferes with an individual’s daily life - with eating, sleeping and other everyday activities. Some people may experience only one episode but it is more common to experience several episodes in a lifetime. It can lead to hospital admission, if the person is so unwell they are at risk of harm to themselves.
Bi-polar disorder

The mood swings in bi-polar disorder can be extreme - from highs, where the individual feels extremely elated and indestructible, to lows, where they may experience complete despair, lethargy and suicidal feelings. Sometimes people have very severe symptoms where they cannot make sense of their world and do things that seem odd or illogical.
Post-natal depression

Many new mothers experience what are sometimes called 'baby blues' a few days after the birth. These feelings of anxiety and lack of confidence are very distressing but in most cases last only a couple of weeks. Post-natal depression is more intense and lasts longer. It can leave new mothers feeling completely overwhelmed, inadequate and unable to cope. They may have problems sleeping, panic attacks or an intense fear of dying. They may also experience negative feelings towards their child. It affects one in ten mothers and usually begins two to three weeks after the birth.
Seasonal Affective Disorder (SAD)

SAD is associated with the start of winter and can last until spring when longer days bring more daylight. When it is mild, it is sometimes called ‘winter blues’. SAD can make the sufferer feel anxious, stressed and depressed. It may interfere with their moods and with their sleeping and eating patterns.




 Cardiovascular disease



Cardiovascular disease (CVD) is a class of diseases that involve the heart or blood vessels.Cardiovascular disease includes coronary artery diseases (CAD) such as angina and myocardial infarction (commonly known as a heart attack).



From the above video, mass information was discovered. Some of this is listed below. 



What is a heart attack?
A heart attack occurs when a blocked artery prevents oxygen-rich blood from reaching a section of the heart. If the blocked artery is not reopened quickly, the part of the heart normally nourished by that artery begins to die. The longer a person goes without treatment, the greater the damage.Symptoms of a heart attack may be immediate and intense. More often, though, symptoms start slowly and persist for hours, days or weeks before a heart attack. Unlike with sudden cardiac arrest, the heart usually does not stop beating during a heart attack. The heart attack symptoms in women can be different than men.

What is cardiac arrest?
Sudden cardiac arrest occurs suddenly and often without warning. It is triggered by an electrical malfunction in the heart that causes an irregular heartbeat (arrhythmia). With its pumping action disrupted, the heart cannot pump blood to the brain, lungs and other organs. Seconds later, a person loses consciousness and has no pulse. Death occurs within minutes if the victim does not receive treatment.
