Can't Sleep - Coffee, Tea and Insomnia

Why can't you sleep after drinking coffee?

We all know coffee and sleep doesn't go together. But tea does -which seems strange since tea contains the same stimulant as coffee (caffeine) although in lower doses.

Coffee Tea

The acknowledge is that tea contains two alkaloids, which are plan to relax the level muscles whilst coffee stimulates the heart, and the respiratory system. Tea thus soothes you more than it stimulates. You can also find caffeine in chocolate, especially dark chocolate, and in some nuts, and of course in many soft drinks. It can also be found in some pain killers and vigor drinks.

This happens when you drink coffee:

o Your heart rate goes up and your Central Nervous system is stimulated.

o Your blood pressure goes up.

o Less blood flows to your skin.

o Your kidneys work harder - maybe manufacture you dehydrated.

o The brain releases more Dopamine.

o Fatty acids are released from fat tissue.

What does all this mean then? Simplified and in short - you feel more awake and alert! You can even feel anxious and over stimulated, some persons get anxious and "hyper".

Caffeine also counteracts the build-up of a natural brain substance called adenosine, which builds up during daytime and which promotes tiredness and sleep.

Now, this is exactly the opposite of what you want when you are getting ready for sleep.

Difficulty going to sleep is a tasteless reaction after coffee, because the brain's normal habit before bedtime is to yield melatonin, which helps to relax us, and to production of adrenaline.

Coffee however, suppresses melatonin and increases the production of adrenaline. In other words, exactly the opposite of what you want!

Some studies have shown that if you drink coffee before going to bed you'll take about twice as long to go to sleep than if you drink decaf coffee. And of course, since coffee might make you anxious and make you feel "hyper" it's not helpful ...

When To Stop Drinking Coffee - Or Caffeinated Drinks

Caffeine is readily absorbed, and you'll have peak concentrations about an hour after you've had your cup. How long it remains in your system varies a lot between people, a fairly tasteless appraisal is that it does take between 3 to 6 hours to disappear.

Why the difference?

Nobody knows, really. Your genes truly play a role, as does how used you are to it. Persons used to drinking coffee can drink more than man who drinks it for the first time.

On median most grown-ups in Europe consume about 200 milligrams of caffeine per day, which corresponds to about 2 - 3 cups of coffee a day (or about 8 cups of tea). This includes soft drinks, so even if you don't drink coffee you probably get some caffeine in your system. The median in the Us is probably higher, maybe twice or even more.

The coffee may be weaker but the servings are bigger!

A good idea if you know you're sensitive is to avoid coffee the last 3 -4 hours before bedtime. Some people - me included! - can drink coffee quite late and it doesn't have any ill effects at all.

will coffee then make you sleep deprived? Give you sleep problems?

Almost truly not, unless you drink impressive amounts or are particularly sensitive. There is a lot of evidence now that the amount of sleep you truly need is often less than you think -as long as the ability of sleep is good.

If you like coffee then remember there is evidence that coffee truly has some very good effects, apart from manufacture you more alert. The newest one comes from the "Alzheimers investigate Trust", suggesting that maybe caffeine is good for memory!

Earlier studies recommend it can be good for some eye conditions "blepharospasm"), and lower your risk of diabetes, Parkinsons disease and more. No proof, just suggestions, but without fail something to think about...

So don't feel bad if you like coffee!
