A growing body of evidence suggests that drinking tea and coffee in moderation can improve health. Studies at Harvard on large groups of people over time have shown that tea or coffee drinkers are less at risk of developing diabetes and possibly cardiovascular disease. However, caffeine can outweigh some of these benefits, especially if you are very sensitive to its effects. Among other things, caffeine can cause restlessness and sleep problems.
If you are looking to reap the health benefits of drinking tea and coffee without experiencing the ill effects of caffeine, decaffeinated is the way to go.
As Holland and Barrett point out, caffeine doesn’t provide any nutritional value, you might want to make the switch.
However, it’s no good that decaffeinated tea and coffee still contain traces of caffeine.
“On average, an 8 ounce (236 ml) cup of decaffeinated coffee contains up to 7 mg of caffeine,” says Holland Barrett.

The main finding is that the substances in decaffeinated coffee can protect neurons in the brain.
This could help prevent the development of neurodegenerative diseases like Alzheimer’s disease and Parkinson’s disease.
How do I know if I have drunk too much caffeine?
According to the Mayo Clinic, going over four cups of caffeinated coffee a day can trigger negative effects.
- Frequent urination or inability to control urination
- Rapid pulse
- Muscle tremors.
Sleep disturbances are a particularly troublesome effect of drinking too much caffeine.
“Even small amounts of sleep loss can add up and interfere with your alertness and daytime performance,” the Mayo Clinic warns.
Additionally, chronic insomnia is linked to a host of serious health issues, such as heart disease.
Whether you opt for caffeine or decaffeinated, there are also indirect health risks to consider.
“If you drink tea or coffee with sugar or have flavored syrups in your coffee drinks, you could unintentionally damage your teeth and add unnecessary calories to your diet,” warns the NHS.
Overloading your calorie intake can promote obesity – a marker of chronic disease.
According to the NHS, a wide variety of artificial sweeteners in tablets or granules are available and are safe to consume in hot drinks.
“But many people who choose to cut the sugar out of their hot drinks quickly get used to the taste,” notes The Health Body.
