You are what you eat as the story goes. Our bodies are made from amino acids, salts, essential fatty acids, sugars, vitamins and minerals along with other essential nutrients obtained from our diet and lifestyle. Vitamin D from the sun, electrolytes from clean water, and fresh oxygen all help to maintain optimal health, build protein chains (hair, fingernails, skin, joints), supply energy to our brain and muscles, rebuild torn tissue, as well as maintain cellular functions. All are contributing to what is referred to as homeostasis in the body, balance.
Researchers have noted this is why we are at our cognitive best in the late mornings and most likely wanting to nap between 2-3pm.
In the same way we perk up in the evenings with our ‘second wind’ and are most likely in our deepest sleep cycle between 3-4am.
It’s believed around 15% of our genes are regulated by our Circadian Rhythm and scientists have linked it to health issues like Diabetes, Obesity, Depression & Dementia through regulation of hormones, although a ton of research is still needed.
