HOW TO DEAL WITH FEAR AND ANXIETY?

Do you ever feel anxious? That faster beating of heart, shivering hands, shaking of legs while speaking in front of people, nausea inducing feeling of great fear and panic?


Anxiety is a state of mind that everyone experiences from time to time. It’s natural to feel stressed before a performance or an exam, or even during a particularly busy or over stimulating period. However, anxiety itself is more than simply 'stress'. If you notice yourself experiencing anxiety for long periods of time, and you can't seem to kick it, a closer examination of this may be beneficial. The following advice may help reduce your anxiety levels, both in the heat of the moment and on a long-term basis.

Anxiety feels like your mind is on fire, overthinking and over analyzing every little, irrelevant thing. Sometimes, it makes you feel restless and constantly distracted. It feels as if your thoughts are running wild in a million different directions, bumping into each other along the way.

Anxious people are those who are most likely processing everything around them so intensely that they can't handle a lot of questions, people or heavy information all at once. Anxiety is when you feel everything

Many people treat it as something lacking in them that other people have. But that’s not a true perception.

When I was in starting days of my engineering college I was enthusiastic about participating in various events which deals with thought process such as speech and debate. Because my thoughts were everything for me. But the big hurdle is to deliver the thoughts in front of several people.

Being anxious there are several imperfection comes in our presentation. Audience starts to feel the less confidence in us. Our voice gets too much high in expressing the thoughts. 

Shivering hands and sweating palms automatically diverts our focus from our thoughts.

Lets understand the SCIENCE OF ANXITY First. Our brain contains an almond shape structure called as Amygdala located deep in the brain. Amygdala is the part of the limbic system responsible for fear and other emotional reactions. When we are going to do any task which is important for life and have risk the amygdala tells Hypothalamus fight or flight response. This release a type of Epinephrine (C9H13NO3) in blood increasing the heart rate. The nervous system then kicks into overdrive and produces some physical symptoms like Shivering hands and shaking legs.

Limbic System


Some tips to get rid of anxiety:

Take a time-out: Practice yoga, listen to music, meditate, get a massage, or learn relaxation techniques. Stepping back from the problem helps clear your head.


Face Your Fears: Fear comes when you try to do something at a single time instance that may be studying for an exam some hours before, delivering a speech without or less practicing, etc. So, break your work in small parts and there will be no confidence require to process that small parts.


Eat well-balanced meals: Do not skip any meals. Do keep healthful, energy-boosting snacks on hand. Avoid carbonated drinks or Soft drinks.

Never Drink Alcohol and Smoke: Our body is made to process good food to stay healthy life, the food that takes your conscious from you is worse. Also it can aggravate anxiety and trigger panic attacks. 

Get enough sleepWhen stressed, your body needs additional sleep and rest.


Exercise daily:  It help you feel good and maintain your health. Do yoga it connects your mind with body. 

Welcome humour:  A good laugh goes a long way and it boosts confidence.


Maintain a positive attitude: Make an effort to replace negative thoughts with positive ones.

Get involved: Volunteer or find another way to be active in your community, which creates a support network and gives you a break from everyday stress.

Learn what triggers your anxiety:  Is it work, family, school, or something else you can identify? Write in a journal when you’re feeling stressed or anxious, and look for a pattern.


Exercise and meditation plays an important role in Anxiety:


Jog, walk, bike, or dance three to five times a week for 30 minutes.

Set small daily goals and aim for daily consistency rather than perfect workouts. It's better to walk every day for 15-20 minutes than to wait until the weekend for a three-hour. Lots of scientific data suggests that frequency is most important. 

Find forms of exercise that are fun or enjoyable. Extroverted people often like classes and group activities. People who are more introverted often prefer solo pursuits.

Be patient when you start a new exercise program. Most sedentary people require about four to eight weeks to feel coordinated and sufficiently in shape so that exercise feels easier.

With meditation, the physiology undergoes a change and every cell in the body is filled with more energy. This results in joy, peace, enthusiasm as the level of Energy in the body increases.


On a physical level, meditation:
  • Lowers high blood pressure
  • Lowers the levels of blood lactate, reducing anxiety attacks
  • Decreases any tension-related pain, such as, tension headaches, ulcers, insomnia, muscle and joint problems
  • Increases serotonin production that improves mood and behavior
  • Improves the immune system
  • Increases the energy level, as you gain an inner source of energy

WHY DO WE STUDY COMPUTERS?

A computer is an electronic device that manipulates information, or data. It has the ability to store, retrieve, and process data. Computer can use type documents, send email, play games, and browse the Web. You can also use it to edit or create spreadsheets, presentations, and even videos.


A computer is a device that accepts information (in the form of digitized data) and manipulates it for some result based on a program or sequence of instructions on how the data is to be processed. Complex computers also include the means for storing data (including the program, which is also a form of data) for some necessary duration. A program may be invariable and built into the computer (and called logic circuitry as it is on microprocessors) or different programs may be provided to the computer (loaded into its storage and then started by an administrator or user). Today's computers have both kinds of programming.

Computers play many important roles in society, helping to promote communication and interaction with others as well as providing users a way to shop, play games and have access to education. Additionally, computers provide a convenient way to create and store valuable information along with media and files, making them particularly useful for businesses.


WHY DO WE STUDY CHEMISTRY?

Every material in existence is made up of matter even our own bodies. Chemistry is involved in everything we do, from growing and cooking food to cleaning our homes and bodies to launching a space shuttle. Chemistry is one of the physical sciences that help us to describe and explain our world.


CHEMISTRY = CHEMICAL + MYSTERY

Chemistry is  knowing of chemicals, there reactions and Product achieved by various chemical reactions.


Chemistry is the study of matter, its properties, how and why substances combine or separate to form other substances, and how substances interact with energy.


Periodic Table of Elements


Five branches

There are five main branches of chemistry, each of which has many areas of study.

1. Analytical chemistry uses qualitative and quantitative observation to identify and measure the physical and chemical properties of substances. In a sense, all chemistry is analytical.

2. Physical chemistry combines chemistry with physics. Physical chemists study how matter and energy interact. Thermodynamics and quantum mechanics are two of the important branches of physical chemistry.

3. Organic chemistry specifically studies compounds that contain the element carbon. Carbon has many unique properties that allow it to form complex chemical bonds and very large molecules. Organic chemistry is known as the “Chemistry of Life” because all of the molecules that make up living tissue have carbon as part of their makeup.

4. Inorganic chemistry studies materials such as metals and gases that do not have carbon as part of their makeup.

5. Biochemistry is the study of chemical processes that occur within living organisms.

Doctors, nurses and veterinarians must study chemistry, but understanding basic chemistry concepts is important for almost every profession. Chemistry is part of everything in our lives.

WHY DO WE STUDY BIOLOGY?

Biology plays an important role in the understanding of complex forms of life involving humans, animals and plants. Understanding these intricate details of life helps humans understand how to care for themselves, animals and plants in the proper manner. Biology helps individuals understand the interaction between humanity and the world. It also develops interests in the lives of living organisms in an effort to preserve them.


Through studying biology, pathologists understand the human body, the functions of various organs, how diseases affect the body and ways to effectively control diseases. Veterinarians have to study biology to appreciate the functions of animals, including marine animals and creatures that live on land. Environmentalists rely on the study of biology to learn how man’s actions affect his surroundings and the ecosystems of other living beings.




Studying biology is the foundation of all characteristics of life on Earth. Apart from creating solutions to the challenges many living organisms face, it paves the way for inventions and discoveries that improve the quality of life. Without studying biology, humans would probably never realize how important maintaining a healthy ecology is for themselves, animals and plant life. Additionally, studying biology enables the use of forensics to trace and arrest errant members of the society. It also allows agriculturalists to rear unique breeds of plants and animals.

WHY DO LUNAR ECLIPSE OCCUR?

An  eclipse happens when a planet or a moon gets in the way of the sun’s light. Here on Earth, we can experience two kinds of eclipses: solar eclipses and lunar eclipses.

Let we understand why do lunar eclipse occur?



During a lunar eclipse, Earth gets in the way of the sun’s light hitting the moon. That means that during the night, a full moon fades away as Earth’s shadow covers it up.

The moon can also look reddish because Earth’s atmosphere absorbs the other colors while it bends some sunlight toward the moon. Sunlight bending through the atmosphere and absorbing other colors is also why sunsets are orange and red.

A lunar eclipse occurs at night during full Moon when the Earth passes between the Sun and the Moon.

The blood moon lunar eclipse sets behind Pikes Peak April 4, 2015 in Colorado Springs.

Every year, there are at least two lunar eclipses and as many as five, although total lunar eclipses are significantly less common. If one knows the date and time of an eclipse, it is possible to predict the occurrence of other eclipses using an eclipse cycle like the saros.

WHY DO SOLAR ECLIPSE OCCUR?

An  eclipse happens when a planet or a moon gets in the way of the sun’s light. Here on Earth, we can experience two kinds of eclipses: solar eclipses and lunar eclipses.

Let we understand why do solar eclipse occur?


A solar eclipse happens when the moon gets in the way of the sun’s light and casts its shadow on Earth. That means during the day, the moon moves over the sun and it gets dark.

While we call it a solar eclipse, astronomers call it an occultation. An occultation happens when an object blocks your view of another object. In this case, the moon blocks your view of the sun.

A solar eclipse occurs in the day time at new moon, when the moon is between the Earth and the sun.



CAUTIONNever look directly at the Sun, even for a second! It will damage your eyesight forever!

To view a solar eclipse, use special solar viewing glasses. Get them from a camera store or online. Welding goggles will also work.

SUNGLASSES DO NOT WORK, EVEN IF YOU STACK MANY OF THEM TOGETHER.
