Liquid of Your life- Water

Can You Imagine Life without Water?

Water is a chemical. Because pure water is homogeneous throughout its structure, it is a pure chemical. It is denoted by H2O. It is composed of identical molecules (H2O), each of which has the same atoms combined and arranged in the same way (with the same proportion of hydrogen to oxygen).

Amazingly, water is a substance. All kinds of organisms benefit from its presence in terms of life and growth, whereas those that lack it suffers from the opposite. It is the only substance that naturally occurs on the planet in all three states—solid, liquid, and gas—and makes up 80% of its surface. Its composition is remarkably straightforward for a substance of such importance. It is the liquid of life.


Chemical Structure of Water

Two hydrogen atoms and one oxygen atom make up the structure of water. Electrostatic attraction is what draws them to one another. The oxygen atom is negatively charged, whereas the hydrogen atom is positively charged. In water, opposites do indeed attract. This charge attraction causes water to be attracted to other water. the same way that atoms are put together. One water molecule's hydrogen will form a bond with another molecule's oxygen atom.

Water is available in three states as:-

1. Liquid

The easiest way to see the water is when it is liquid. After all, it covers the majority of the planet. Water can only change states when a few specific conditions are met, and water can only stay in its current state as long as those conditions are met. For instance, for water to remain a liquid, the temperature must be between 32 and 212 degrees Fahrenheit. Precipitation is the main way that liquid water reaches the Earth's surface. Water vapor will condense into liquid water in this process. This results in the formation of clouds, which then brings about precipitation and the return of water to us.

2. Solid (Ice)

Ice is simply water that has frozen over. Water expands as it freezes, encasing air molecules as it does so. In actuality, it is the only known non-metallic substance that will expand in this way. Ice will float in a glass of water for this reason. It can become ice without necessarily being in a liquid state. Water vapor has the ability to condense into ice crystals, such as frost. From snow and hail to icebergs and icicles, ice can be found in the environment in many different forms.

3. Gas (H2O Vapor)

When water is in its gaseous state, it is a vapor. There are several ways for this to happen, but it mostly does so at temperatures higher than 212 degrees Fahrenheit. Water boils above this point and transforms into steam, a vapor that can be seen. Below this temperature, water can also exist, as when you can see your breath on a chilly day. Evaporation, or the absorption of liquid water into the atmosphere, is a further process by which water can turn into vapor. A wet surface is allowed to dry would be an illustration of this. That water simply evaporated into the air around it rather than dissipating.

Properties of water

On Earth, in addition to the three states, water has a variety of special qualities. Water doesn't shrink as it gets colder like the majority of liquids do. At about 39 degrees Fahrenheit, water stops shrinking, and as the temperature drops further, the process reverses and it begins to expand. Cohesion is a different property that describes how water is drawn to other water. It has a high specific heat capacity.

Chemistry of Psychotropic Drugs (Chemotherapy of Mind)


The brain is thought to contain 100 billion neurons. Neurotransmitters are molecules that serve as "chemical messengers," carrying messages along neuronal pathways in the brain. A neurotransmitter is released by the first (sending) neuron into the synaptic cleft, a tiny space between neurons, where it binds with receptors on the second neuron. According to the saying, the neurotransmitter "fits into the receptor like a key into a lock." The second (receiving) neuron's firing can either be inhibited by this binding action or caused to fire. An inhibitory response reduces the activity of the neuronal network, while an excitatory response moves the message along the neuronal pathway. The chemical messenger is then "transported" back into the first neuron to complete the message and is then saved for later use.

In research, Hyman observed that all psychotropic drugs interfere with the brain's normal neurotransmitter function. However, the brain has a number of feedback mechanisms to monitor the activity of its neurotransmitters, and in response to the drug's disruption of that function, it undergoes a number of "compensatory adaptations." The brain strives to continue operating normally. For instance, the brain reduces its own serotonergic activity when a drug increases serotonin levels. The brain increases its dopaminergic activity if a drug blocks dopamine receptors and so on. According to Hyman, the brain is now functioning in a way that is "qualitatively as well as quantitatively different from the normal state" at the conclusion of this compensatory process. The key concept here is that all psychiatric medications interfere with neurotransmitter function, which causes compensatory changes that result in abnormal brain function. So, 

What are Psychotropic Drugs?

Psychotropic drugs are those that alter mood, perceptions, and behavior. It is also known as Psychoactive or Psychopharmaceutical. Psychotropic drugs, especially when used in conjunction with psychotherapy, can be effective tools in the treatment of conditions such as borderline personality disorder (BPD), anxiety, bipolar disorder, depression, and schizophrenia. A broad class of medications known as psychotropics is used to treat a wide range of ailments. They function by modifying the concentrations of neurotransmitters such as dopamine, gamma-aminobutyric acid (GABA), norepinephrine, and serotonin in the brain. The psychotropic drugs fall into five main categories:

1. Anti-anxiety medication

2. Antidepressants

3. Antipsychotics

4. Stabilizers of mood 

5. Stimulants

Some psychotropic drugs can have very severe side effects and necessitate special monitoring by medical professionals.

How does it work?

As already mentioned, Psychotropic drugs are used to treat symptoms of mental illness such as mood swings, rage, hallucinations/delusions, and other issues that can interfere with therapy. With these symptoms under control, you can concentrate on learning skills to cope with and manage your mental health. These medications work by affecting the balance of neurotransmitters in your body, such as serotonin, dopamine, and -Aminobutyric acid (GABA). These chemical messengers transport signals between your organs to help them function properly. They assist neurons in communicating with one another in the brain to control mood, concentration, perception, and other aspects of brain function. They are specific to the cells that they attack.

How quickly do psychotropic drugs start working?

You may notice side effects right away in some cases, but you may not feel the full beneficial effects for several weeks or even months. If you believe your medication isn't working, consult your doctor to discuss alternatives. Never discontinue a psychotropic medication on your own; this can be dangerous and unpleasant. To avoid this, your doctor will know how to gradually reduce your dosage.

Note:- Never take psychotropic drugs (or any other prescription drugs that have not been prescribed to you) unless you have a prescription.
