Bad News, Friends: Coffee Doesn't Actually Count Toward Your Daily Water Intake

  Bad News, Friends: Coffee Doesn't Actually Count Toward Your Daily Water Intake You'd be hard-pressed not to find a coffee-lover just about anywhere you go, and rightfully so. Not only can the sweet aroma of coffee be the perfect (and, let's be real, usually necessary) start to our mornings, but it also has tons of health benefits and can even help you lose weight. But does the water in coffee count toward your recommended daily intake of water? There are conflicting views regarding this because it's thought to be a diuretic (i.e. it makes you urinate more frequently), which makes it work against the antidiuretic hormone that our bodies produce.

A physician found a person’s response to caffeine is likely determined by two main genetic factors: whether their liver can metabolise caffeine quickly or slowly, and whether they carry a genetic variation that makes their central nervous system more sensitive to it.

Dr J Langer said coffee drinkers fall into one of three major groups: high, regular and low caffeine sensitivity.

Try one of these caffeine alternatives if you suddenly want to avoid coffee

Here are some of the best caffeine alternatives if you want to stop drinking coffee.It’s also worth pointing out that acrylamide has always been in coffee. It’s a byproduct of the roasting process, not an additive. While the chemical is still being studied, there aren’t any specific links between acrylamide in coffee and cancer. If anything, you need to be more worried about getting cancer from cigarette smoke before giving up your cup of joe.

In this regard, caffeine increases the sensitivity of neurons to stimuli. For you science types , the euglycemic, hyperinsulinemic clamp technique was used and glucose uptake was This measurement period occurred three hours after the exercise and one hour after the caffeine administration.

“It’s common for people to ask their doctor questions such as why they are kept awake by one cup of coffee, while their partner easily falls asleep after five cups,” said Dr Langer. “The answer is that we are all unique coffee drinkers. Our genetic make-up programmes our reaction to caffeine, just as it programmes our hair colour and eye colour.”

High sensitivity to caffeine 

If you find even the slightest amounts of caffeine gives you a boost and more than one cup of coffee keeps you up all night, it’s likely you have high sensitivity to caffeine.

This is likely due to slow-metabolism in the liver and ‘high binding’ in the central nervous system – basically it impacts the central nervous system more). 

Nocturnal 'night owls' risk early death

  Nocturnal 'night owls' risk early death People who stay up late and struggle in the mornings are more likely to die early, a new study has found.  Tracking 500,000 Britons over six years, researchers found night owls had a 10% greater risk of premature death than those who go to bed early and spring out of bed in the mornings.The risk was the same even when common problems night owls have, like metabolic dysfunction and heart disease, were factored in.The scientists behind the work are calling for employers to better adapt work schedules to fit their employees' sleep patterns.

Reports delivered within 24 hours. Another genetic link to caffeine sensitivity involves the type of adenosine receptors a person has in his/her brain. You should be able to identify your level of caffeine sensitivity based on the three descriptions above.

Kathy Smolewska and colleagues identified three forms of sensitivity measured by the Highly Sensitive Person Scale: Ease of Excitation, Low Sensory Threshold, and Aesthetic Sensitivity . Are you particularly sensitive to the effects of caffeine ?

Regular sensitivity to caffeine 

People with this level of sensitivity can generally drink 2-5 cups of coffee a day without sleep issues or adverse reactions.

It’s thought regular sensitivity is caused by a balance between caffeine inactivation in the liver and binding in the central nervous system.

For this group, caffeine is normally not recommended in the evening.

Low sensitivity to caffeine 

If you can drink coffee before bedtime and it doesn’t affect your sleep, you most likely fall into this category. An individual with low sensitivity to caffeine probably will not experience the typically desired effects of caffeine throughout the day, such as wakefulness, alertness and increased concentration.

It occurs because their body metabolises caffeine quickly.In this group, higher intakes of caffeine can be consumed, although people should have no more than five cups of coffee per day for health reasons.

The research is shared in a new report authored for the Institute for Scientific Information on Coffee.

Ryanair hikes fees for priority boarding - which passengers need if they want to take a suitcase in the cabin .
Previously, passengers could take a large bag such as a wheelie suitcase and a small bag such as a handbag on board.  But the budget airline changed its policy in January so that passengers with two bags could take the smallest into the cabin, then stow the larger bag in the hold free of charge.  © Provided by Associated Newspapers Limited Ryanair has hiked some of its fees and the only way to avoid paying is to buy priority boarding The only way of getting around this was by paying for priority boarding. Now Ryanair has made this expensive.
