😢 Why do we cry?

We cry because our eyes need to stay wet and clean! 🌊 When we feel sad, happy, or even when something gets in our eye, our body makes tears to help us feel better or wash away the yucky stuff.

There are three types of tears:

• 😊 Happy tears – when we laugh or feel super happy!
• 😢 Sad tears – when we feel upset or hurt.
• 🧼 Cleaning tears – when dust or onion smells bother our eyes.

Tears are like little helpers for our eyes!

Tears are our body’s way of taking care of our eyes and emotions! 😊😢 There are three main types:

1. Basal tears – Always keep our eyes wet so they don’t dry out.
2. Reflex tears – Wash away dirt or irritants (like onion fumes!).
3. Emotional tears – Released when we feel strong emotions (sadness, joy, or even anger).

Scientists say emotional tears contain stress hormones, so crying can actually help us feel better! 💙

Crying is a complex biological and emotional process. Here’s why it happens:

1. Physical Protection

Tears contain lysozyme, an enzyme that kills bacteria, keeping eyes safe from infections. Reflex tears flush out irritants instantly.

2. Emotional Release

Emotional tears contain higher levels of stress hormones (like ACTH). Crying signals distress to others and may trigger empathy.

3. Social Bonding

Humans are the only species that cries emotionally. Studies suggest tears strengthen social connections by showing vulnerability.

🌍 Cultural note: In some cultures, crying is encouraged, while others see it as weakness.
