If you have a tension headache, place a heating pad on your neck or the back of your head. If you have a sinus headache, hold a warm cloth to the area that hurts. A warm shower might also do the trick.
If your ponytail is too tight, it could cause a headache. These "external compression headaches" can also be brought on by wearing a hat, headband, or even swimming goggles that are too tight.
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.
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.
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.
