Benefits of Caffeine

Improve energy levels. One of the reasons why people love coffee so much is that it rids of tiredness. This is mainly because coffee contains caffeine. Once our bloodstreams have absorbed the caffeine, it travels to our brain and enhanced the firing of neurons, which resulted to increase energy levels. 

Helps burn fat. Caffeine can be found in almost every commercial fat-burning supplement. Studies show that it can boost your metabolic rate and is one of the natural substances to burn fat. 

Reduces the risk of Parkinson’s and Alzheimer’s Disease. Studies show that lifelong caffeine consumption might reduce the development of Alzheimer’s Disease. The same goes for Parkinson’s Disease, where a study also concluded that those with higher coffee consumption have lower risks of developing the said condition. 

Memory booster. Johns Hopkins University suggested that drinking coffee after a learning session helps with long-term memory. 

Risks of Caffeine

Depression. If you are already diagnosed with depression, you might have to lower your caffeine intake. Research published in Korea in 2016 found out that higher caffeine intake is linked to a higher risk of severe depression. 

Blood Sugar. People diagnosed with type 2 diabetes observed a rise in blood glucose levels after caffeine consumption. There is some evidence that linked caffeine to an impairment in insulin action, which contributes to a small but detectable rise in sugar levels. 

Insomnia. When you consume coffee 3 to 6 hours before bedtime, there is a higher chance of sleep disruption. 

How to cope up with caffeine withdrawal?

If you noticed that you are consuming an unhealthy amount of caffeine every day and want to limit it, do it gradually. Don’t abruptly stop, doing so can cause withdrawal symptoms, such as headaches, anxiety, and nervousness. 

However, caffeine withdrawals are not dangerous but they are not exactly the most pleasant feeling in the world. If you are unsure of how to proceed or if you are already experiencing withdrawal symptoms that affect your daily life, it’s best to consult your health care provider about it.
