32+ Zeitgebers (Biological Cues) And How To Enhance Your Circadian Rhythm

Right now as I write this, I am watching the morning sun, sitting on a bench in Dolores Park with my shirt off an laptop out - in 50ºF weather!

Last night I had no sleep as I just traveled from FL to CA and helping my brother pack until 4am… and I woke up around 5am (8am my normal time… thanks jetlag).

That’s why I believe today’s topic of discussion should be circadian rhythm cues, also called Zeitgebers.

Zeitgebers (the German word for “time givers”) are signals that help synchronize the body's circadian clock with the environment.

In this post, we will discuss the most common zeitgebers, how they affect our circadian rhythm, and how we can use them to enhance our sleep, stress, weight, social life, and more.

256+ Ways To Increase Dopamine Naturally (Supplements And Genetics)

Dopamine is extremely important for everyday function and plays a much larger role in the body than just bonding, motivation, cognition, emotion, well-being, and movement.

Unfortunately, our environment today is very good at manipulating and hijacking our dopamine system.

In this post we will discuss, how/why dopamine is produced, how chronic inflammation affects dopamine, what are some quick fixes for dopamine, and what are some long lasting dopamine builders, as well how to avoid losing dopamine.

How Chronic Fluoride Can Damage Mitochondria And The Gut Biome

Fluoride is a trace element, but it is found in our daily exposure more than a "trace". 

In small amounts, it appears to be okay

The problems with fluoride appear to be in chronic use of it over long periods of time, and/or being exposed to a high dose of it in a single instance. 

Apart from skeletal tissue and teeth, fluoride can cause changes in the kidneys, liver, thyroid, parathyroid, pituitary gland, testis, muscle tissues, stomach, brain, neurons, and immune system. 

I have mild dental fluorosis, probably from drinking too much fluoridated water, using fluoridated toothpaste, along with taking fluoride at the dentist to protect my enamel.

Blue Light's Unique Effects On Our Health

In 1958, researchers looked at how each unique color affected organisms. 

They found out that blue light could change the circadian rhythm of algae, and this was later found out to be true with humans as well. 

Our understanding about blue light has increased and I have summarized what the literature shows to date.

Blue light is quite powerful and has the power to reset/disrupt our circadian rhythms, but if used and timed properly it may mitigate diseases like diabetes, obesity, depression, anxiety, bulimia, schizophrenia, dementia, and Parkinson's Disease. 

Some of the reasons (more explained below) is because blue light influences hormone secretion, heart rate, alertness, sleep, body temperature, and gene expression.

Why You Need To Get Out Into The Sun

In common day western society, we are consistently bombarded by artificial light.

Our workspaces are indoors, powered by fluorescent blue lights (which blue has its own negatives).

We only get sun rarely and it's either partial (such as through glass while driving to work) or too much (single sessions of long periods hanging out at the beach).

We also try to supplement for the sun by taking vitamin D hormone supplements, which is not as bioactive for creating the active form vitamin D.
