Caffeine in food is not bad as it is generally safe in moderate amounts. Indeed, caffeine has its advantages in the system; it is an healthy beverage that contains a substance that may boost your mood, metabolism and mental and physical performance but when consumed in high quantity, there can be unpleasant consequences and damage to health.
Also, tolerance level for caffeine differs in individuals and according to research, the genes determine tolerance level. Consequently, the level of caffeine that affects each person determines on what the person’s system can manage
Caffeine is known to increase alertness by blocking the effects of adenosine, a brain chemical that makes you feel tired. At the same time, it triggers the release of adrenaline, the “fight-or-flight” hormone associated with increased energy. And when too much is consumed, effects may become more pronounced, leading to anxiety and nervousness; this is known as caffeine-induced anxiety disorder. Additionally, modest doses have been shown to cause rapid breathing and increase stress levels when consumed in one sitting (11Trusted Source, 12Trusted Source).
Caffeine’s ability to help people stay awake is one of its most prized qualities and it makes it difficult to get enough restorative sleep. Caffeine can help you stay awake during the day, but it may negatively impact your sleep quality and quantity.
While caffeine helps with bowel movement in many people; a laxative effect that has been attributed to the release of gastrin, a hormone the stomach produces that speeds up activity in the colon, large doses of caffeine may lead to loose stools or even diarrhea in some people.
Muscle breakdown, also known as rhabdomyolysis, a condition which causes damaged muscle fibers enter the bloodstream, leading to kidney failure and other problems can be cause by too much consumption of caffeine.
Caffeine is addictive just like some drugs. Going without caffeine for several hours may lead to psychological or physical withdrawal symptoms in those who consume large amounts on a daily basis.
And while caffeine doesn’t seem to increase the risk of heart disease or stroke in most people, it has been shown to raise blood pressure in some when consumed at high doses or prior to exercise though this effect may only be temporary, so it’s best to monitor your response.
Coffee, like other caffeinated beverages is a known energy booster but it can also have the opposite effect by leading to rebound fatigue after the caffeine leaves your system. So, although caffeine provides energy, it can indirectly lead to fatigue when its effects wear off. Aim for moderate caffeine intake to help minimize rebound fatigue.
Increased urination is a common side effect of high caffeine intake due to the compound’s stimulatory effects on the bladder. In addition, high intake may increase the likelihood of developing incontinence in people with healthy bladders.
It should be noted that moderate caffeine intake seems to provide impressive health benefits in many people while high dosages may lead to side effects that interfere with day-to-day living and wellness.
