Most of us know the energizing buzz we get from drinking a cup of coffee. But could our love for this caffeinated elixir be doing more harm than good? Can drinking too much coffee cause tingling?
Studies have revealed too much caffeine can have a range of effects on our health and wellbeing. Multiple suspected side-effects have been linked to excessive caffeine consumption, one of them being tingling sensations in various body parts including the hands, fingers and fingertips.
Coffee-drinkers, used to their daily fix, may not consider the potential harmful impact of overdoing it. According to research, a moderate intake of caffeine for the average adult is about 400 milligrams per day; equivalent to four cups of coffee.
It’s worth noting a large or ‘grande’ cup of some coffee franchises contains around 300-400mg of caffeine; meaning two or more of these could easily exceed the recommended daily allowance.
Excessive caffeine consumption can alter nerve impulses in the body, thus causing tingling sensations in the hands, feet, fingers and lips. It’s also been known to increase heart rate and blood pressure – something medical experts say should be monitored, with those suffering from heart conditions particularly vulnerable.
Drinking more than four cups of coffee each day greatly increases the odds of these types of side effects emerging. In fact, caffeinated drinks have been known to cause tingling in some people with little-to-no previous history of abnormal caffeine consumption.
Going without coffee for a period of time can reduce the likelihood of unwanted side effects, however the process is often hard for those hooked on their daily fix. There is a range of caffeine-reduced coffees and tea-based substitutes available, meaning you can still enjoy your favourite hot beverages without necessarily overdoing it.
Health and Wellbeing Risks
Research has shown excessive coffee consumption can lead to insomnia, chronic headaches, irritability, depression and indigestion, not to mention other neurological symptoms. The physiological effects of consuming too much coffee or energy drinks can lead to an increased risk of heart palpitations, and in the most serious of cases, trigger panic attacks.
The Mayo Clinic, one of the most renowned medical practices in the US, recently conducted a study on the potential impacts of caffeine intake. Results revealed certain people’s psychopharmaceutical makeup can lead to increased sensations of tingling and numbness, with levels even higher those consumed through coffee.
The consensus from medical professionals is that coffee can be enjoyed responsibly, however drinkers should be aware of their own personal limits to avoid the risks of long-term and short-term health concerns.
Potential Benefits on Mental Health
Coffee has been suggested to have a wide range of potential benefits, mostly related to mental health. Studies show caffeine can help with increased focus, alertness and creativity, enabling us to enhance productivity and performance.
Caffeinated beverages have been known to improve mood, treat headaches and provide relief from constipation and other digestive issues. Some studies have also revealed potential links between coffee consumption and improved long-term health, including reduced chances of developing diabetes and suffering from stroke.
That said, as with anything, too much caffeine, in any form, can lead to serious health complications. Medical experts stress individuals consider their own circumstances – caffeine can affect us all in different ways.
Sensitivity to Caffeine
Individuals can differ in their sensitivity to caffeine, with some responding to larger doses of caffeine quicker than others. While rare, there have been cases reported in medical literature where individuals can overreact to caffeine, resulting in excessive tingling, weakness, nausea and vomiting.
The effects of caffeine can be similar to an allergic reaction, so it is important to know your own personal limits. And, if experiencing any unusual symptoms as a result of drinking coffee, it’s highly advised you speak to your doctor.
Reasons to Cease Drinking Coffee
Aside from potential health risks associated with excess coffee consumption, there are a variety of reasons why people may choose to give up their daily fix; the impact on mood and sleep habits, unpleasant tastes, financial costs, and even an inability to properly digest the caffeine.
Scientific research further suggests that for individuals prone to tingling sensations or similar symptoms, abstaining from coffee or energy drinks may be the best solution long-term.
Alternatives to Coffee
It’s possible to reduce caffeine intake without going cold turkey on your hot beverages. Coffee doesn’t have to be eliminated from the diet (unless deemed medically necessary) as there are a range of caffeine-reduced and deliciously non-caffeinated alternatives.
Green tea is perhaps the most popular substitute, containing far less caffeine than regular coffee. Studies have suggested green tea has a range of health benefits, such as improved heart health, blood pressure and preventing the onset of chronic diseases.
Other alternatives include decaffeinated coffee, chamomile tea, yerba mate and herbal teas. Those giving up regular coffee should experiment to find what works best for them, as the taste of decaffeinated coffee may not always suit everyone.
Identifying Triggers
Sickness, stress or hormones can all serve as caffeine triggers. Similarly, certain people may believe they need a cup of coffee throughout the day to remain energized. Such an attitude can lead to caffeine dependency; if you’re unsure whether you have a problem, it can be helpful to monitor your own consumption.
Habitual coffee drinkers may feel as though they are unable to function without regular consumption. While this isn’t necessarily a medical diagnosis, it goes to show just how easily our bodies can adapt to a certain lifestyle. Experiencing symptoms such as tingling on a regular basis may indicate a reliance on caffeine.
Tingling Sensations Symptoms
The symptoms of tingling sensations can range from mild to severe. Those experiencing pins and needles or numbness in their limbs may find massaging the area or taking a break from drinking coffee can help reduce the symptoms. If the symptoms persist or worsen see your doctor for a medical opinion.
As with anything, it comes down to responsible consumption. Maintaining a controlled caffeine intake is one way to reduce the risks of developing long-term health complications.
Expert Advice
There is no black and white answer when it comes to the effects of drinking coffee. Caffeine sensitivity will vary from one to the other; what works for some may not work for others. It’s important to be mindful of your own habits, seek medical advice and keep an eye on regular side effects.
Drinking coffee occasionally can provide a beneficial buzz, however medical professionals warn against going overboard on your daily consumption. Becoming too reliant may lead to a range of health complications and an inability to function without.
Genetic Impacts of Caffeine Intake
The amount of caffeine people should consume is often based on studies and general guidelines. However, recent research suggests genetics play a bigger role when it comes to finding one’s own caffeine tolerance levels. Some will experience adverse effects from low levels of caffeine intake, whereas others may be able to consume coffee or energy drinks every day without any problems.
The secret to reducing any potential caffeine-related health complications strictly lies within understanding how to manage one’s own intake. Research suggests people with a family history of heart and neurological conditions should exercise the most caution when consuming caffeinated drinks.
Where to Get Help
Ultimately it’s not just the number of cups of coffee we drink — it’s also the amount of caffeine we take in that can affect us. Those experiencing regular symptoms should speak with their doctor to identify potential sensitivities, allowing them to modify their caffeine intake if necessary.
Alternatively, professional dieticians can provide assistance and advice on adjusting one’s caffeine intake. As with anything diet related, any medical advice should be taken seriously with regular check-ups.
Avoiding Burnout
Coffee burnout is something people often forget to think about. Caffeine can be highly taxing on the body and affect mood, energy levels and cognitive functioning. Regular breaks from drinking any form of caffeine can help alleviate mental and physical fatigue.
It’s important to consider one’s own lifestyle when drinking coffee, taking into account factors like professional or academic workloads, current diet and regular physical activity habits.
The benefits of a balanced diet should never be overlooked, with a proven link between physical health, mental health and the food we consume. Eating right, drinking in moderation and exercising regularly can go a long way towards mitigating the potential impacts of drinking too much coffee.
