Coffee acts like a drug. Almost billions of people rely on it to go through a very busy and hectic schedule. It is the most popular beverage worldwide and about 30-40% of its population consumes it every day.
Coffee is always the talk of the town because of its effect on the human body. It does more than just keeping you alert and awake.
Some studies show its benefits on health, while others indicate serious health issues.
Coffee has caffeine, a natural stimulant for the central nervous system. To be more precise, it’s not about how coffee affects the human body but more about how caffeine affects it.
According to the FDA, 400mg is a healthy coffee intake for adults. However, children and pregnant women should be cautious with the amount they take.
Reading the label and measuring cup size is also essential for the correct intake of caffeine. Also, age, overall health, and body weight are important factors that one should check since those affect coffee’s influence upon the body.
Short Answer: Coffee can be beneficial for your body as it contains many antioxidants and has been proven to lessen the risk of a few diseases. However, excessive coffee intake can be dangerous to your body as well.
Drinking too much coffee daily makes you build a tolerance to it.
Coffee affects your body in various ways that make you question what does coffee does to your body?
Let’s find out the effects of caffeine on your body.
Long Term Effects of Caffeine
Caffeine causes several long-term effects on your body. Drinking a healthy amount of coffee regularly proves to protect you against diseases such as Parkinson’s and Alzheimer’s.
Let’s look into other effects of caffeine on the body in detail.
Central Nervous System
Caffeine is a central nervous stimulant used in many drugs to treat migraines, headaches, and drowsiness.
All health benefits come from high-octane coffee while decaf coffee is not that impactful.
Coffee helps you stay awake and alert, however, overconsumption can lead to:
- Withdrawal syndrome
- And Death( yes, death)
Overdose of caffeine drugs eventually leads to death due to convulsion.
The safe amount is 400mg of caffeine per day. Anything above this amount can cause health risks.
Coffee can cause increased blood pressure. This happens when caffeine causes arteries to widen the blockage of hormones or increase adrenaline.
Moreover, caffeine is not a safe drink for people with irregular heart rhythms. An overdose might cause issues in breathing or rapid heart rate. You can read about how coffee can affect your blood pressure in my other article to know more.
Skeletal and Muscular systems
Caffeine can hinder the absorption and metabolism of calcium. This can contribute to osteoporosis or bone thinning.
Overconsumption of caffeine may also cause your muscles to twitch.
Digestive and Excretory Systems
Coffee helps you digest faster by boosting the stimulating process. But, it can also cause acid reflux due to stomach acid.
It can also be known to cause upset stomach and heartburn.
Doctors warn pregnant women not to take too much caffeine. Caffeine overdose can cause slowed fetal growth and increase the risk of miscarriage.
Although a cup of coffee is safe during pregnancy, I still recommend talking to your doctor first before consuming any amount.
What Happens If You Drink Coffee Every Day?
Drinking coffee every day makes you dependent on caffeine.
Daily consumption of caffeine stimulants leads to many health benefit issues and risks.
You will feel more alert and focused on work. Plus, studies show that caffeine increase brain activity and neurotransmitters such as norepinephrine and dopamine.
Other studies indicate those who drink coffee daily are less depressed than those who don’t.
According to the Journal of Medicine, a daily cup of java reduces the risk of premature death in people above 50 than those who don’t drink coffee daily.
Coffee has also been linked to lower body fat in women, especially those who drank two to three cups a day. Caffeine improves physical performance and helps burn fatty acids in the blood.
However, keep in mind that coffee alone won’t make you slim and fit. A healthy diet and daily exercise help you maintain a healthy weight.
When you have work piled up and nights when you need to prepare for the exam, coffee works like magic that saves your day. However, if you find yourself drinking it every day, it leads to addiction.
The reason behind addiction is because caffeine binds with adenosine receptors in the brain that block sleep pressure. This makes the body create more adenosine that the average amount of caffeine cannot bind with increasing receptors in the mind.
In layman’s terms, this causes low energy levels and tiredness, which make you crave more coffee.
Not getting enough coffee daily make you develop withdrawal symptoms, including headache, irritability, inability to focus, and exhaustion. This further leads to a disturbing sleep routine.
So, daily coffee intake is not harmful, but the key is to keep the daily consumption in check to avoid all the side effects.
In conclusion, if you find yourself drinking coffee daily, stick to a moderate amount. (average amount here points toward 400mg coffee per day).
