Many sufferers fail to spot the first stage of a migraine: the prodrome phase. It is characterized by pronounced yawning, drowsiness, food craving, sensitivity to light, increased thirst, or blurred vision. These symptoms can happen days or hours before the onset of a migraine.
The best way to recognise the symptoms is by keeping a record of your day: what you ate, your exercise habits, what you drank, how you felt at different points.
Sleep deprivation takes a sharp toll on the human brain and body, impairing cognition, motor ability, and mood. Willpower, memory, judgement, and attention all suffer. You drop and bump into things, crave sugar, overeat, and gain weight. You're more irritable, more anxious, overly negative, and more emotionally reactive.
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.
I'm extremely pleased to be writing about this topic. It's something I have been paying great attention to over the last 2 years. Brain function has not nearly been discussed enough in the past, however seems to be picking up speed over the last few years.
