Caffeine provides no nutritional value on its own. It’s tasteless, so you won’t necessarily know if it’s in your food either. It can be found in soft drinks, nescafe, tea etc. Even some medications may contain caffeine without your knowledge. Caffeine has various side effects despite the benefits when used frequently and in excess (It is addictive, you know).

The following are effects of caffeine on:

Central nervous system
Caffeine acts as a central nervous system stimulant. When it reaches your brain, the most noticeable effect is alertness. You’ll feel more awake and less tired, so it’s a common ingredient in medications to treat or manage drowsiness, headaches, and migraines.Studies have found that people who drink coffee regularly have a lower risk of developing Alzheimer’s and dementia, and cutsuicide risk by 45 percent. These benefits are limited to people who drink high-octane coffee, not decaf. Some people consider coffee to be a health drink, but like most foods, over indulging can cause side effects. For example, too much caffeine can give you headaches. This is primarily linked to caffeine withdrawal.The blood vessels in your brain become used to caffeine’s effects so if you suddenly stop consuming caffeine, it can cause a headache.Other symptoms of caffeine withdrawal include: anxiety, irritability, drowsiness.
In some people, sudden withdrawal may cause tremors.Although it’s extremely rare, it’s also possible to overdose on caffeine. Symptoms of an overdose include: confusion, hallucinations, and vomiting. An overdose can result in death due to convulsions.Overdosing happens by consuming large amounts of caffeine, most often in energy drinks or diet pills.Up to 400 milligrams of caffeine is considered to be safe, according to the Mayo Clinic. This equals about 4 cups of coffee, although the amount of caffeine in beverages varies widel

Digestive and excretory systems
Caffeine increases the amount of acid in your stomach and may cause heartburn or upset stomach. Extra caffeine doesn’t get stored in your body either. It’s processed in the liver and exits through your urine. This is why you might have an increase in urination shortly after having caffeine.If you have experience stomach problems, like acid reflux or ulcers, ask your doctor if it’s okay for you to have caffeine.

Circulatory and Respiratory systems
Caffeine is absorbed from your stomach. It reaches its highest levels in your bloodstream within an hour or two.Caffeine can make your blood pressure go up for a short time. This effect is thought to be attributed to either an increase in adrenaline or a temporary block on the hormones that naturally widen your arteries. In most people, there is no long-term effect on blood pressure, but if you have irregular heart rhythms, caffeine may make your heart work harder. If you have high blood pressure (hypertension) or heart-related problems, ask your doctor if caffeine is safe for you to consume.An overdose of caffeine may cause rapid or irregular heartbeat and breathing trouble. In rare cases, caffeine overdose can result in death due to convulsions or irregular heartbeat.

Skeletal and muscular systems
Caffeine in large amounts may interfere with absorption and metabolism of calcium. This can contribute to bone thinning (osteoporosis).If you consume too much, caffeine may cause also your muscles to twitch.If experiencing caffeine withdrawal, a symptom may include achy muscles.

Reproductive system
Caffeine travels within the bloodstream and crosses into the placenta. Since it’s a stimulant, it can cause your baby’s heart rate and metabolism to increase. Too much caffeine can also cause slowed fetal growth and increased risk of miscarriage. In most cases, a little caffeine is safe during pregnancy.According to the Mayo Clinic, you should limit caffeine consumption between 200 and 300 milligrams per day if you’re trying to get pregnant. There’s some evidence that large amounts of caffeine can interfere with the estrogen production and metabolism needed to conceive.
