THE TRUTH ABOUT ALCOHOL

CAFFEINE
Caffeine is a drug that is naturally produced in the leaves and seeds
of many plants.
It acts as a natural pesticide that paralyzes and kills certain insects
feeding on the plants.
It's also produced artificially and added to certain foods.
Caffeine is defined as a drug because it stimulates the central
nervous system, causing increased alertness.
Caffeine gives most people a temporary energy boost and elevates
mood.
PHYSICAL EFFECTS OF CAFFEINE
• Increased heart rate, respiration, and/or blood pressure.
• Sweating
• Frequent urination  dehydration

CAFFEINE
Caffeine is a diuretic
Diuretic: a substance that results in the body producing an
increased amount of urine
Our bodies generate ADH (anti-diuretic hormone)  needed for
water reabsorption  diuretics block ADH  instead of
absorbing water, it is excreted as urine.
GOT THE JITTERS??
Many people feel that
caffeine increases their
mental alertness, and it
can. However, higher
doses of caffeine can
cause anxiety, dizziness,
headaches, and the jitters.
Caffeine can also interfere
with normal sleep   
CAFFEINE AND HEADACHES
Many times pain medication that is designed to treat headaches
contains caffeine.
The caffeine in the medication is meant to “override” the headache
and provide alertness and a feeling of well-being.
Long-term caffeine use/abuse can lead to the caffeine being the
reason for the headaches and migraines.
QUITTING CAFFEINE
Caffeine can be the cause of migraines, headaches,
nausea, and the jitters.
Ironically, going cold turkey and quitting heavy caffeine
use can actually cause all of those symptoms as well.
