How Much Caffeine Is Too Much?

Are you aware of how much caffeine you are consuming? Understanding how caffeine affects you, from energy levels to sleep quality. It is also essential to be aware of the recommended limit of caffeine intake and to ensure that you are not drinking too much.

Caffeine is a widely consumed stimulant, found naturally in seeds, leaves and fruit. It can boost energy levels and alertness, making it a popular choice for those needing a pick-me-up. It is extracted from these sources and used to create coffee, tea, chocolate and energy drinks.

For most people, a moderate amount of caffeine shouldn't cause problems. But you might want to consider cutting back if you have a health condition like heart palpitations or anxiety or if you're having trouble sleeping or relaxing.

This article provides an overview of caffeine and how to determine if you are consuming too much.

How Much Caffeine Should I Have In A Day?

Limiting caffeine intake to no more than 400mg daily, equivalent to around four to five cups of coffee or tea, is advised to stay healthy. Other sources of caffeine include chocolate, energy drinks, and certain soft drinks. It is important to note that the sensitivity to caffeine varies between individuals.

Doctors suggest that pregnant women limit their caffeine intake to less than 200mg daily; some even eliminate caffeine while trying to conceive or get pregnant. This is because some researchers believe the only way to ensure safety is to abstain altogether from caffeine.

How Caffeine-Rich Are Coffee, Tea, And Energy Drinks?

The following are the approximate caffeine levels found in everyday foods and drinks:

• Black tea (1 cup) – 48mg
  
  
• Dark chocolate (100g) – 43mg
  
  
• Flu or cold medicine (standard dose) – 50mg
  
  
• Energy drink (240ml) – 72mg
  
  
• Fizzy drink (1 can) – 34mg
  
  
• Medium coffee (Americano, latte, cappuccino) – 173mg
  
  
• Green tea (1 cup) – 12mg

What Does Caffeine Do To My Body?

Caffeine is a stimulant that can help you overcome fatigue and exhaustion. This is why it is popular in the morning or during physical or mental exertion. Your metabolism can be boosted by caffeine, and this can increase your physical and mental performance.

Studies have demonstrated that consuming a moderate amount of caffeine may have health benefits, such as a lowered risk of stroke and diabetes and even a longer life expectancy. However, the exact mechanism by which this occurs is still unknown. My research suggests that drinking a moderate amount of caffeine may be associated with increased longevity, though the exact mechanisms are still unknown.

How Do I Know If I’ve Had Too Much Caffeine?

Consuming excessive caffeine can lead to feelings of restlessness, nervousness, and discomfort in your stomach. Your body might react with a flushed feeling and a racing heart. People not accustomed to caffeine may be particularly susceptible to these reactions.

After ingesting caffeine, it takes approximately 15 minutes for the effects to start showing, and they can last for multiple hours.

Is Caffeine Dangerous For My Heart?

Contrary to popular belief, people with heart conditions may still be able to consume caffeine in moderation. While it can temporarily increase blood pressure, particularly in those with hypertension, research suggests moderate caffeine consumption is generally safe.

If your blood pressure is within a healthy range and you don't experience any abnormal heart palpitations, there is usually no need to make drastic changes to your habits. Caffeine should be consumed moderately and you should monitor how it affects your body.

It is essential to know that caffeine-containing foods and drinks may also be high in cholesterol-raising sugar and fat, such as coffees with cream or syrups and non-diet sodas. Therefore, it is essential to watch what you consume in order to maintain a healthy heart.

Could I Be Addicted To Caffeine?

Many scientists are uncertain if caffeine is addictive, as it does not cause physical or mental harm or lead to excessive use as other drugs do.

By preventing the action of adenosine, a neurotransmitter that induces feelings of drowsiness, caffeine keeps us alert and awake. When caffeine consumption is discontinued, the effects of adenosine become more prominent, leading to feelings of fatigue and exhaustion.

Daily consumption of coffee or energy drinks can lead to mild withdrawal symptoms if you miss your regular dose. This makes it difficult to break the habit, creating a cycle of dependency.

What Happens If I Cut Out Caffeine?

Quitting caffeine consumption abruptly can result in physical effects, such as:

• Headache
  
  
• Problems concentrating
  
  
• Tiredness
  
  
• Anxiety
  
  
• Low mood or feeling easily annoyed
  
  

The effects of caffeine withdrawal will start to be felt 12-24 hours after your last caffeine dose. Symptoms of caffeine withdrawal can last between 2-9 days.

How Can I Become Less Dependent On Caffeine?

Consuming too much caffeine can have several adverse effects, including difficulty sleeping, increased anxiety over time, and a reliance on caffeine to keep alert. The effects of caffeine can be mitigated by reducing your intake and improving your overall wellbeing.

Making gradual changes to one's habits is advantageous as it decreases the likelihood of experiencing withdrawal symptoms.

1. Reduce Your Intake Slowly

Start by cutting back by 100mg daily, so start by having one less cup of coffee in a week and then gradually reduce your intake.

2. Go For Decaf Swaps

Replacing your caffeinated drinks with decaffeinated or low-caffeine beverages could be done gradually.

3. Introduce A Brisk Walk

Instead of relying on caffeine, why not take a brisk walk in the fresh air? The endorphins released during physical activity can give you the same mood-boosting effects as caffeine.

4. Avoid Caffeine Before Bedtime

Avoiding caffeine for at least 6 hours before bedtime is advisable to get a good night's sleep.

When Should I Speak To A Doctor About Caffeine?

If you are pregnant, breastfeeding, or under 18, speaking to a doctor before consuming caffeine is essential. Additionally, if you have any existing health conditions, discussing with a doctor how much caffeine is safe to consume would be beneficial.
