The blocking of adenosine receptors in the brain also causes the brain to become ‘excited’. Try removing caffeine for 4 weeks and notice the difference it makes to your ability to fall asleep and quality of sleep, it may surprise you.
If a person is having a morning coffee, a mid-afternoon coffee, and then some dark chocolate after dinner, they are topping up the caffeine in their body every few hours - this means that come bed time their blood caffeine level will still be too high, making sleep difficult. The consumption of caffeinated products is one of the main reasons people struggle to fall asleep early enough to get enough sleep before they have to wake up again. When caffeine is present in the blood stream it is nearly impossible for the brain to produce melatonin – our sleep hormone. It takes the body 5-6 hours to process caffeine and excrete it from the body however, trans-fats, the contraceptive pill, medication, and poor liver healthy can increase this clearance time - extending the amount of time caffeine remains circulating in the blood stream. Caffeine binds to the adenosine receptors in the brain, thus preventing adenosine from causing the chemical cascade that tells the brain to initiate sleep or rest. One of the main concerns of consuming coffee regularly is the effect it has on sleep.
It is the most commonly used drug in the world. Caffeine is a stimulant, found in coffee, energy drinks, tea, soft drinks and chocolate. Too many people are surviving on caffeine, rather than thriving with out it. Then there are others that tell me they don’t drink any coffee but have two diet energy drinks and a bar of dark chocolate each day, they tell me that because it’s a diet drink or dark chocolate it must be healthy, right? Many clients sit down and tell me that they absolutely can not get out of the door in the morning unless they have had a coffee, or that there is no way that they can stay awake in their mid-morning meeting unless they have had their daily triple shot. Read below to find out what I had to say about caffeine…Ĭoffee has a cult following worldwide, photos of lattes fill Instagram every Sunday morning, and coffee dates are the basis of most friendly catch-ups - but it is time to get real about the effect caffeine has on your health. We report evidence that guarana seeds provide additional stimulation over caffeine alone, and document the changes to this stimulation in the context of both caffeine and glucose.Recently I was featured on Food Matters, a health and wellness website filled the articles and documentaries from some of the world’s top health experts.
To gauge the stimulant effects of guarana we studied how it altered the locomotor activity of the planarian species Dugesia tigrina. The locomotor activity and convulsive response of planarians with substance exposure has been shown to provide an excellent system to measure the effects of drug stimulation, addiction and withdrawal. To appreciate the stimulant effects of guarana and other natural products, a straightforward model to investigate their physiological properties is needed. Yet, despite the growing use of guarana as an additive in energy drinks, and a burgeoning market for it as a nutritional supplement, the science examining guarana and how it affects other dietary ingredients is lacking. The mix of other natural chemicals contained in guarana seeds is thought to heighten the stimulant effects of guarana over caffeine alone. Guarana is a climbing plant native to the Amazon whose seeds contain approximately four times the amount of caffeine found in coffee beans. Many energy drinks also contain other ingredients that might enhance the tonic effects of these caffeinated beverages. The stimulant effect of energy drinks is primarily attributed to the caffeine they contain.
