Caffeine Effects On The Body
What Is Caffeine?
A stimulant is an overarching term that covers many drugs including those that increase the activity of the central nervous system and the body.
They are pleasurable and invigorating, or drugs that have sympathomimetic effects.
This is the world’s most widely consumed psychoactive drug.
What Are The Caffeine Effects On The Following:
1. Caffeine Effects On The Blood
Blood pressure (BP) is the pressure of circulating blood on the walls of blood vessels.
Most of this pressure is due to work done by the heart by pumping blood through the circulatory system.
Used without further specification, “blood pressure” usually refers to the pressure in large arteries of the systemic circulation.
Blood pressure is usually expressed in terms of the systolic pressure(maximum during one heartbeat) over diastolic pressure (minimum in between two heartbeats)
It is measured in millimeters of mercury (mmHg), above the surrounding atmospheric pressure.
The eﬀect of caﬀeine on blood pressure in habitual consumers and abstainers has been investigated in more than 50 acute and 19 repeated-dose clinical trials with healthy or hypertensive subjects (reviewed by Myers 1988, 1998, James 1991c, Green, et al. 1996).
The results of the acute studies indicate that it induces an increase in systolic (5–15 mmHg) and/or diastolic (5–10mmHg) blood pressure
This occurs most consistently at doses >250mg/person, in adults of both sexes, irrespective of age, race, blood pressure status, or habitual caﬀeine intake
2. Caffeine Effects On Heart rate
Heart rate is the speed of the heartbeat measured by the number of contractions (beats) of the heart per minute (bpm).
The heart rate can vary according to the body’s physical needs, including the need to absorb oxygen and excrete carbon dioxide.
It is usually equal or close to the pulse measured at any peripheral point. Activities that can provoke change include physical exercise, sleep, anxiety, stress, illness, and ingestion of drugs.
The American Heart Association states the normal resting adult human heart rate is 60–100 bpm
Tachycardia is a fast heart rate, defined as above 100 bpm at rest
It works by increasing the rates of depolarization at the SA node
3. Caffeine Effects On Sleep
Sleep is a naturally recurring state of mind and body
It is characterized by
Altered consciousness, relatively inhibited sensory activity, inhibition of nearly all voluntary muscles, and reduced interactions with surroundings.
It is distinguished from wakefulness by a decreased ability to react to stimuli, but more reactive than coma or disorders of consciousness, sleep displaying very different and active brain patterns.
During sleep, most of the body’s systems are in an anabolic state, helping to:
Restore the immune, nervous, skeletal, and muscular systems
These are vital processes that maintain mood, memory, and cognitive function, and play a large role in the function of the endocrine and immune systems
It typically prolonged sleep latency, reduced total sleep time and sleep efficiency, and worsened perceived sleep quality.
Dose- and timing-response relationships were established.
The sleep of older adults may be more sensitive compared to younger adults
It may disturb sleep, but only in sensitive individuals.
4. Caffeine Effects On Your Brain
Alertness is the state of active attention by high sensory awareness such as being watchful and prompt to meet danger or emergency or being quick to perceive and act.
It has many positive actions in the brain and can increase alertness and well-being, help concentration, improve mood and limit depression
5. Caffeine Effects On The Elderly
In older adults, memory is typically best in the morning and gradually declines over the day.
Those who consumed caffeine in the morning showed much better memory, both short-term and long-term than those who consumed a placebo, especially in the late afternoon, where memory and attention may be most crucial to daily functioning for the elderly.
This is further supported by a study which showed that adults over the age of 65 who regularly consume caffeine in the morning are much more alert and function at a higher cognitive level throughout the day.
The authors conclude that it is beneficial for older adults to regularly consume average doses of caffeine in the morning to boost cognitive performance and alertness in the afternoon.
Again, one should not exceed the recommended dose of about 300 mg per day, otherwise, memory performance declines due to over-consumption.
