The migraine
The hallmark of the migraine attack is a wave of excitation across the brain quickly followed by a wave of inactivity.
The neurochemical changes associated with these waves cause the blood vessels to narrow in the head. Since a lack of blood-flow in the head can be deadly, our body reacts with a massive blood vessel dilation in response. The heightened activity in your brain means you will have trouble moving, thinking, remembering things, and photophobia. In effect, migraines shut us down until the neurchemical balance is restored.

How to Powerhouse through Sleep Deprivation
Sleep deprivation
Willpower, memory, judgement, and attention all suffer when you are sleep deprived.
You drop things, crave junk food sugar, overeat, gain weight. You’re more irritable, negative, emotio...
Get through sleep deprivation:
- Stabilize your blood sugar, by eating hearty food (protein and fat) more often.
- Reduce refined carbs and increase fats and proteins.
- B-complex vitamin supplements can give you an immediate boost in alertness and mental clarity.
- Soak in an Epsom salt bath - might even help you get enough energy to exercise the next day.
- Drink more water than you usually do to help compensate.
- Exercise is the single best way to “take out the trash” in your body, and after staying up more hours than you should.

This Is How Your Brain Becomes Addicted to Caffeine
Coffee As An Addictive Substance
- Coffee is the world’s most popular psychoactive drug, with over 80 percent of American adults having it daily.
- Quitting caffeine produces withdrawal symptoms like ...
How Coffee Affects Us
- When we have coffee, it gets absorbed in our gut as well as in our bloodstream. As the chemical is soluble in water and fat both, it can easily enter the brain.
- Adenosine, a molecule present in our brain which is remarkably similar to caffeine, is responsible for a feeling of tiredness.
- Caffeine acts like a doppelganger and is able to fit in the receptors that adenosine fits, preventing any tiredness to occur for a few hours.
- The surplus adenosine now floating in the brain signals that adrenal gland to produce and secrete adrenaline, which is also a stimulant.
Addicted To Coffee
The chemistry of the brain changes when a person takes a regular intake of caffeine, as it grows more adenosine receptors.
Eventually, it takes more caffeine to feel the effects, and as there are now more receptors, not having a stimulant results in ‘caffeine withdrawal headache’ and other symptoms due to the original molecule connecting to the increased number of receptors in the brain.
