The more we learn about the gut, its special intelligence becomes clear. A growing body of evidence suggests that the trillions of microbial inhabitants that live within us have a deep, complex relationship with our health and nervous systems, including our allergies, diabetes, and cancer, as well as, more mysteriously, with our brains and behavior.

This “brain in your gut” is transforming the scientific society’s familiarity with the connections between digestion, emotion, health, and even the way you think. Many scientists now refer to the gut’s neurons as “the second brain.”

Yet, a growing body of evidence links guts microbiota to gastrointestinal and extragastrointestinal illnesses. Dysbiosis and gut inflammation have been related to the development of numerous mental diseases, including anxiety and depression, which are common in today’s culture.

First, Understanding Our Brain

The brain utilizes the most energy of any organ in the body; under normal physiological conditions, the brain generates ATP mostly from glucose. When glucose is scarce, such as during prolonged fasting, ketone bodies become an important energy source for the brain.

Any mitochondrial damage and inflammation were related to cognitive problems. Research shows People with higher inflammation has cognition problem.

Inflammation Inhibits Brain Chemicals, Decreases BDNF production in Hippocampus.

Do you know that certain inflammation in your body leads to detrimental brain chemicals?

It’s critical to take brain inflammation seriously since it causes damage to and death of brain cells, speeding up the aging process and causing atrophy of the brain.  Studies showed on mice provide great insight into how the types of bacteria in your gut can influence your inflammation levels.

According to anthropologists, many ancient cultures placed a high value on dreaming and the stages of sleep. Some cultures believed that when a person slept, their soul entered another world. The idea that sleep slows down the body and brain to the point where it is almost dead was perhaps more prevalent in Western history.

Sleep is a physical and mental state in which the nervous system is mostly inactive, muscles are relaxed, and consciousness is suspended. It is also regarded as a condition of relaxation. Sleep is essential for survival, and sleep time influences morning testosterone levels in older men.

Yet, your body detoxifies during sleep by removing free radicals. Detoxification is crucial since free radicals can cause sickness and cancer. Also, according to research, people who are sleep-deprived report increases in negative moods (anger, frustration, irritability, sadness) and decreases in positive moods. More than %60 percent of the daily testosterone release in men occurs during sleep. (source)

As you can see, sleep affects our testosterone levels and other hormones. This article will dive deeply into sleep, testosterone, and brain health.  

Bullet Points

Low testosterone levels have been associated with sleep deficiency and severe sleep apnea. Total sleep time influences morning testosterone levels in older men. (source)

The effects of sleep loss on testosterone levels were clear. Male testosterone levels dropped by 10–15% after five hours of sleep. This shows that sleep is directly correlated to testosterone level.

During sleep, hypothalamic neurons release sleep neurotransmitters, including GABA and galanin, while inhibiting dopamine, histamine, norepinephrine, and serotonin neurons (monoaminergic neurons).

Human growth hormone secretions are the most important for one man and a female. The more you deep sleep, the more you have growth hormones because growth hormone surge is largely sleep-dependent hormones. Also, High-intensity, GABA, and intermittent fasting increase HGH the most, but in my opinion, forms of exercise are beneficial. Still, I believe Brazilian Jiu-jitsu is the best for increasing self-defense while enjoying exercise benefits.

According to human research, blood testosterone levels will fall when cortisol is administered into the circulation while the body is at rest. Evidence that increased cortisol levels by over-exercise may eventually lead to decreased circulating testosterone levels and impair sleep quality.

You can optimize your testosterone while lowering sleep, increasing healthy fats, exercise, and good quality sleeps. However, the best way lower stress or handles stress is using Cognitive Behavior Therapy, meditation, Hypnosis, and Wim hof breathing. Also, some adaptogens and supplements such as Rhodiola Rosea With B vitamins, Magnesium with B6, and Vitamin D are good for this regard.

Understand Testosterone and the Brain

When performing stress tasks, testosterone appears to activate a distributed cortical network called the ventral processing stream, and adding more testosterone enhances spatial cognition in both younger and older hypogonadal men. Furthermore, low testosterone is linked to depressive disorders.

Rhodiola Rosea

Stress can wreak havoc on the human body, including brain health, resulting in many health complications. Fortunately, there are many ways to combat stress and live a healthier lifestyle.

The side effect of chronic stress is enormous—people who have chronic stress have a lower quality of life, brain, and overall functions.

Do you know chronic stress affects the level production of BDNF protein?

BDNF is essential when it comes to memory and learning. Not at all; it also involves the process of mood regulation and more! (source)

Chronic stress has detrimental effects on creating BDNF protein. Yet, people have a high level of BDNF associated with a high level of stress resilience, better learning, and a high level of memory recall! (source)

Brain decline is a common concern of modern society. Fortunately, many nootropics can help combat this decline. Nootropics are substances with neurological benefits, and they come in the form of supplements, drugs, or plants.

Combine with Tyrosine

Tyrosine alone isn’t as effective as other supplements such as Rhodiola Rosea. These are great combinations when it comes to improving cognitive functions better way. You can add caffeine for further improvement.

Tyrosine does not have a strong nootropic effect, but amino acid is the main ingredient in dopamine production and adrenalin hormones.

Caffeine is excellent cheap, and nootropic. However, some people can’t tolerate caffeine well.

Do not exceed caffeine intake too much, and combine with it L-tyrosine for better results.
