Does drinking (too much) coffee make you jittery, anxious or makes it harder to fall asleep? You’re not alone.
There’s a lot of conflicting evidence about coffee. Some research states that a moderate caffeine consumption may actually be good for you, while other studies found adverse side-effects of excess caffeine, like insomnia, anxiety and heart palpations.
One of the explanations for these mixed results may lie in your genes. Thanks to genetic variations, some people produce a less active version of the enzyme responsible for metabolizing caffeine than others. If that’s the case, caffeine will stay in your body and brain for a longer period of time. As a result, the physiological effects of caffeine will be more pronounced. That’s why slow-metabolizers experience are more sensitive to consuming caffeine than fast-metabolizers.
And of course, things like your liver health, use of oral contraceptives or being pregnant also play a role in caffeine sensitivity.
Whatever your reasons for wanting to cut back on caffeine, you can still wake up to a warming, energizing drink. Try these 9 coffee alternatives to start your day off with a bang.
