2.2.1 Negative Hormonal Side Effects from Caffeine Intake
Too much caffeine can have a massive negative impact on your body when under
stress. Although it can give you a quick boost when required, the fatigue will catch up
once the caffeine has worn off. You should not need caffeine to focus, and if you do,
this lack of focus is your body’s way of telling you it needs rest. An over excess of
caffeine can lead to negative effects such as restlessness, lapses of concentration
and a decrease in your ability to be fully effective.
Caffeine also has a massive impact on the hormones in your body. The following
hormones are increased under the influence of caffeine. Adenosine - Alerts you but causes sleep problems in the future. Adrenaline - Gives you an extra boost but will make you feel fatigued once
the adrenaline has worn off. Cortisol - The Stress hormone. Makes you crave fatty foods. Dopamine - Initially makes the person feel good but once worn off, generates
a low and possible dependence/addiction
2.2.2 Weight Issues
As mentioned, the amount of cortisol produced by stress gives the person a strong
urge to divulge in foods that are high in carbohydrates, sugars and fats. This pattern
of eating will result in excess fat being stored around the upper half of your body
(mainly the abdomen). This type of fat around the abdomen can lead to serious
health problems, mainly concerning the heart. Continued stress will only make this
problem worse.
2.2.3 Poor Health and Immune System
Under stress, the body’s natural defences can be severely affected and leave the
person with a weaker immune system. This leaves the person more prone to
contracting illnesses. If the stressed person falls ill, then this will only lead to an
increased amount of stress inflicted on the body.
