What Is Depression?

Depression is a mood disorder that affects your thoughts, feelings, and daily life. It is not the same as being sad. Sadness is temporary and has a clear cause. Depression lasts longer and affects how you see yourself, the world, and your future.

Depression is a real medical condition that affects:

  • Mood
  • Energy
  • Sleep
  • Appetite
  • Motivation
  • Concentration
  • Relationships
  • Daily functioning

People with depression cannot “snap out of it.” Depression is caused by real changes in the brain and body, mixed with life events, stress, and sometimes genetics.

Different Types of Depression

Many people do not know there are different types of depression. Online, people often search:

Here are the main types.

1. Major Depressive Disorder (MDD)

What Causes Depression?

Millions of people ask:

  • Why am I depressed for no reason?
  • Is depression genetic?

  • What chemical causes depression?

Depression is complicated, but here are the most common causes.

1. Brain Chemistry Changes

Depression involves changes in neurotransmitters such as:

  • Serotonin
  • Dopamine
  • Norepinephrine
  • GABA

These chemicals help control mood, motivation, and stress. When they are out of balance, it can lead to depression.

2. Genetics

Depression can run in families, but it does not guarantee you will have it. Genetics can increase risk, but environment and life experiences also matter.

3. Trauma and Stress

Events like:

  • Childhood trauma
  • Loss
  • Breakups
  • Illness
  • Work stress
  • Abuse
  • Neglect

4. Physical Health Problems

Chronic pain, thyroid problems, hormonal changes, or serious illnesses can raise the risk of depression.


5. Lack of Sleep

Poor sleep affects mood, energy, memory, and stress levels. Many people search:

Why does depression make me so tired?

The answer is: depression and sleep problems often go together.

6. Social Isolation

Loneliness is one of the strongest triggers for depression, especially in 2026 as more people work from home.


7. Life Changes

Even positive changes can lead to depression, such as:

  • Moving
  • New job
  • Ending a relationship
  • Becoming a parent

Change can bring stress, and stress can affect mood.
