Most people can not wake up without a cup of morning coffee, and the good news is that coffee is associated with numerous health benefits such as longevity and reduced risk of dementia. However, a double dose may also lead to a side effect that you may not have associated with coffee before. Of course, you do not have to give up your favorite beverage, but be careful not to overdo it!
From too much coffee you can become pretty nervous - caffeine stimulates the central nervous system while simultaneously increasing the levels of adrenaline, dopamine and glutamate. This combination can lead to anxiety, nervousness, rapid heartbeat, irritability and even anger.
Energy drops you throughout the day
Coffee can quickly irritate you and give you a run of energy, but when that energy is consumed it will come to a very strong fall. Some research has also shown how caffeine can destroy productivity, which can lead to delusions at work (just the opposite of the effect you want to achieve).
\You go to the toilet very often
Caffeine is a diuretic, which means that you drink more often by drinking coffee, especially if you do not drink coffee often. While research shows that you can not actually dehydrate coffee, if you do not drink enough water, your body will not be hydrated enough.
Your sleep schedule is disturbed
Scientists agree that coffee can disturb the dream and reduce its quality and length. Even if you consume coffee 6 hours before going to sleep it may happen that you can not sleep in the evening. Coffee can also disrupt your body's daily rhythm, which is why you will feel tired and slow down during the day.
