Is consuming caffeine regularly good or bad for your body?
- Caffeine can stimulate the adrenal gland, resulting in cortisol levels shooting up
- Caffeine’s stress response causes disturbances in the blood sugar levels
- The beverage can hinder our ability to sleep if consumed before bedtime
For most people, a cup of freshly-brewed coffee is the first meal of the day. It induces a feel-good vibe and instantly wakes them up. While the right amount of coffee has several health benefits, excessive consumption of the beverage can be disadvantageous.
Caffeine affects the sleep cycle
The beverage can hinder our ability to sleep if consumed before bedtime.
“Caffeine primarily stimulates the central nervous system in our body which directly affects the neurotransmitters in the brain — The basic effects include sleeplessness and heightened awareness levels for an acute duration as caffeine directly engages with the sleep-inducing molecule adenosine and latches itself onto the adenosine receptors in the brain to cause alertness and sleep inhibition,” nutritionist Mugdha Pradhan, Founder, Thrive FNC told the Indian Express.
Caffeine affects the endocrine system
Caffeine can stimulate the adrenal gland and produce adrenaline in the blood, resulting in cortisol levels shooting up and increase in heart rate.
“As this process releases glucose stores in the body, caffeine causes high sugar level which further increases insulin level. The rise in insulin causes a fall in the body’s sugar level which leads to mood slumps and pangs of lethargy,” Pradhan told the outlet.
Caffeine affects the blood sugar level
Caffeine’s stress response causes disturbances in the blood sugar levels and can also result in insulin resistance, substance dependency and weight gain in some cases.
Caffeine affects the digestive system
People usually tend to intake more amount of the beverage to increase the metabolism. This results in the focus being diverted from the digestive system.
“In accordance with the stress response activated by caffeine, energy and focus are diverted from the digestive system of the body. As the body often identifies caffeine as a toxin, the body attempts to eliminate the toxin via bowel movement,” Pradhan explained.
Coffee addiction and withdrawal system
The beverage “belongs to the mild drugs category and can cause major dependency,” the nutritionist explains. Some of the withdrawal symptoms include inactiveness, headaches, low energy level, irritability and muscle pain.
