Caffeine is the most popular psychoactive substance on the planet. Its presence in tea, coffee, and energy drinks makes us feel active immediately after intake. But the effects of caffeine are very serious to health. After feeling energetic, one may feel dizziness or get an upset stomach. That happens when caffeine is consumed in excess. In light or moderate usage, caffeine doesn’t prove to be harmful to users. Caffeine affects people in different ways. Since 90% of the world population is consuming caffeine, its effects must be known.

Positive

  1. Alertness: We feel alert after consuming tea or coffee in the morning. We get rid of our sleep for completing our tasks. This is because caffeine blocks adenosine receptors in the brain, preventing the brain from falling asleep and making us attentive.
  2. Pain relief: Intake of coffee reduces inflammation and blocks the pain receptors in the brain, working as a pain relief medicine.
  3. Stamina: Caffeine influences the method by which our muscles use glycogen, allowing them to function much better before fatigue arrives.
  4. Productivity: Drinking tea or coffee increases the output of dopamine levels in the body. Dopamine keeps us in a positive state of mind helping us to accomplish our tasks well.
  5. Neurological diseases: Caffeine manipulates the brain to release important neurotransmitters which have a positive impact on our health. Dopamine release reduces the chance of Parkinson’s and Alzheimer’s disease. Caffeine consumption can prevent many cases of hyperactivity disorders.

Negative

  1. Insomnia: Since caffeine helps us in staying alert, its intake later in the day will give rise to insomnia. This will affect the sleeping schedule of the person which has severe effects.
  2. Addiction: Caffeine is addictive and overcoming it isn’t easy. The effects of caffeine addiction will have serious implications over the heart and digestive system of the body.
  3. Severe heart conditions: Caffeine increases the heart rate of the body. People with heart conditions will experience negative effects of tea and coffee as caffeine gives rise to heart complications. It doesn’t give rise to heart abnormalities, but the intake is still unsafe.
  4. Anxiety: The blockage of adenosine by caffeine intake causes anxiety attacks. Caffeine-induced anxiety is a popular issue among excess caffeine users. Even moderate users are prone to anxiety due to caffeine.
  5. Digestive issues: People consume caffeine in the morning as it helps them to keep the bowels moving. The laxative effect of caffeine is very popular, but excess consumption may lead diarrhea. Gastroesophageal reflux disease (GERD) is a serious case of caffeine intake. People with a sensitive stomach should not consume caffeine.
