In this text, we will answer the question “when should you start drinking coffee?”. We’ll show you the effects of caffeine on your day and the recommended dose. In addition, we will discuss the harmful effects of excessive consumption of caffeine.
When should you start drinking coffee?
The ideal is to eat something before having the coffee drink, this will help to improve nausea and stomach pains. Thus, it is recommended to start drinking coffee after eating some food.
Why does coffee make me nauseous?
When consumed in excess, it is normal to have nausea with coffee consumption. Or in cases where the person has a health problem, such as gastritis.
Coffee stimulates the production of hydrochloric acid in the stomach, irritating the organ and causing pain, discomfort and even heartburn.
The discomfort is mainly perceived by those who suffer from gastritis, a condition characterized by the presence of superficial lesions in the stomach mucosa. If taken on an empty stomach, coffee can worsen the burning sensation in the stomach.
Another point that should be noted is the amount consumed. For those who already have some gastric dysfunction, the less coffee is ingested, the less discomfort the person will feel. But generally speaking, a “safe” amount for coffee to be considered a harmless beverage is on average up to four cups a day.
Excessive coffee consumption
There is a phrase that says “the dose makes the poison”. Coffee is no different. Although there are some benefits proven by science, a drink when not consumed in moderation can be harmful to your health.
Among the consequences of excessive consumption are insomnia, headaches and gastrointestinal problems such as reflux and heartburn. Listed below are the main effects of excessive caffeine consumption:
- Dry mouth
- Nausea and vomiting
There is no reason to panic because the consumption of coffee considered to be safe is quite high. Coffee is not scientifically proven to cause diseases, but excessive consumption is associated with uncomfortable effects and some illnesses.
What is the relationship between caffeine and sleep?
The substance caffeine has the ability to bind to the same adenosine receptors, inhibiting its activity and accelerating neural activity.
No matter how much adenosine we have accumulated, caffeine blocks the receptors, causing the feeling of sleep and fatigue to momentarily cease, but after the caffeine wears off, we feel the effects again.
With an effect of about 6 hours your body will still be processing a cup of coffee you had in the morning, until late in the afternoon. When you increase your caffeine dose or consume it later, your sleep is negatively affected.
Caffeine can be a big problem for people with insomnia, making a one-time problem a few nights chronic. It is known that caffeine consumption delays the onset of sleep, decreases total sleep time and increases the number of awakenings throughout the night.
As sleep is essential for health and quality of life, sleep and wake cycles are regulated by a fine tuning existing between homeostatic and circadian processes.
Caffeine can also completely modify the phases of your sleep, reducing the amount of deep sleep, which is the critical phase for physical and mental rejuvenation.
On the other hand, caffeine can help with the “jet lag” of intercontinental travel and those who suffer from some disorders of the circadian sleep-wake cycle.
To reconcile the pleasure and beneficial actions of coffee with the need to sleep, it is recommended to avoid coffee in the eight hours before bedtime.
Why when I drink a lot of coffee I can’t sleep?
The caffeine present in coffee disrupts the quality and quantity of sleep.
With an effect of around 6 hours, your body will still be processing a cup of coffee you had in the morning, until late afternoon, meaning when you increase your caffeine dose or consume it later, your sleep is negatively affected.
Caffeine has the ability to bind to the same receptors as adenosine, inhibiting their activity and accelerating neural activity.
It is as if caffeine “tricks” the brain: no matter how much adenosine we have accumulated, caffeine blocks the receptors, causing the sensation of sleep to momentarily stop.
What are the recommended doses of caffeine?
Drinking too much coffee can cause symptoms such as upset stomach, tremors and even insomnia. The maximum recommended dose of caffeine per day is 400 mg, equivalent to drinking about 600 ml of bag coffee per day or 3 espressos.
However, it is necessary to be careful and also account for the intake of other products containing caffeine, because caffeine is present in energy drinks, in some training supplements, some medicines, green, mate and black teas and even in cola-type soft drinks.
