Morning coffee: beware of this bad habit that you should avoid when you wake up
Drinking coffee after a difficult night, according to a new study, increases the bodys glycemic response by 50%. This bad habit could increase the risk of diabetes and cardiovascular disease.
Coffee is often considered a remedy after a difficult night. And for good reason: the effects of caffeine provide an energy boost to start a new day. However, a recent study published in the British Journal of Nutrition suggests that waking up coffee can have a negative impact on blood sugar control, that is, blood sugar levels. This habit could thus promote the risk of diabetes and cardiovascular diseases.
What are the consequences of having a coffee when you wake up?
For the purposes of the study, researchers from the Center for Nutrition, Exercise and Metabolism at the University of Bath (UK) recruited 29 male and female participants. The scientists asked them to undergo three tests:
In the first test, the volunteers slept from 11 p.m. until 7 a.m. without any sleep disturbance. When they woke up, they drank a sweet drink.
In the second test, the scientists woke the participants every hour for 5 minutes. They also got a sweet drink when they woke up.
In the latest test, the participants also had a restless nights sleep with wake-up calls every hour. This time, they had a fairly strong black coffee 30 minutes before sipping the sugary drink.
A coffee as soon as you wake up could affect your blood sugar control
Result: A restless night did not worsen the blood sugar response compared to a good nights sleep. However, the researchers observed that black coffee increased the blood sugar response in the participants by 50%. According to scientists, previous studies have shown that coffee can create insulin resistance. Therefore, caffeine could limit the bodys ability to tolerate blood sugar from breakfast.
"Simply put, our blood sugar control is affected when we drink coffee immediately after waking up, especially after a disturbed nights sleep," said Harry Smith, lead author of the study, in a statement. "It is possible to improve this situation by eating first and then drinking coffee if you still feel the need. This can have important beneficial effects on health," recommended the researcher from the Department of Health at the University of Bath.
