How Much Coffee Is Too Much Coffee?
Caffeine has its perks, but it can also pose problems. People who are susceptible may find they feel the effects after just one cup of coffee or tea, while others won’t feel effects until 3-4 cups of coffee. If you rely on coffee to get you going, you are not alone. Caffeine stimulates the nervous system, alleviates fatigue, increases alertness, and improves concentration and focus.
For most adults 200-300mgs (about 2 cups of coffee) a day isn’t harmful. Heavy caffeine use however, where you are consuming 500mgs – 600mg a day may cause the following symptoms, and may need limiting.
- Stomach upset
- Racing heartbeat
- Muscle tremors
How you react to coffee is subjective and varies from one person to the next. People who do not regularly drink coffee tend to be more susceptible to its effects, as regular coffee drinkers have built up a tolerance to the drug. Body mass, age, medication use and health conditions (such as anxiety disorders) can also play a part. There is also research to suggest that men are more susceptible to the effects of caffeine than women.
Taken in moderation, caffeine is harmless and may even be beneficial. Just keep an eye on your intake – whether an espresso, flat white, green tea or chocolate – be aware of your daily caffeine intake and it affects. If you are worried or stressed, or if you are pregnant, have less than 200mg a day.
