1. Water returns us to our natural state:
We’re connected to water from the onset of life. Babies’ bodies are 75 percent water. As we age, we become drier (only 60 percent), but our brains are still three-fourths water and even our bones are 31 percent water.
The brain, which rests in a kind of “clear, colorless cerebrospinal fluid” in our heads, reacts to water very fondly because, “our ancient ancestors came out of the water and evolved from swimming to crawling to walking. Human fetuses still have ‘gill-slit’ structures in their early stages of development,” and the water in our cells “is comparable to that found in the sea.”
2. We’re more relaxed along the coast:
Areas of the brain associated with less stress and more empathy are activated when we look at nature scenes. While pictures of urban landscapes elicited activity in the parts of our brains associated with stress, participants who were shown nature pictures had heightened activity in the parts associated with “positive outlook, emotional stability and the recollection of happy memories.”
3. Looking at pictures is good, but water is even better:
While looking at pictures is one thing, it turns out the real-life natural world also wins over urban landscapes. People are happier when they were outside, but they are happier when near bodies of water.
4. Water rejuvenates a tired mind:
Now we have more screens to touch, social networks to update and websites to refresh, and our fatigued brains need to recharge.
Water, helps that happen.
5. Blue soothes:
Blue, it turns out, is the world’s favorite color. We evolved on a planet that is primarily shades of water and sky blue, so it makes sense that blue stimulates a positive emotional response. The arousal mechanism stimulated by blue’s wavelengths correlates to the release of neurotransmitters thought to be associated with feelings of euphoria, joy, reward, and wellness related to the effects of dopamine.
