It contains caffeine, which is a stimulant increasing alertness and wakefulness. Coffee also improves focus and concentration. In addition, coffee can help improve your physical performance. Caffeine increases the release of adrenaline, which gives the body a boost of energy.
As Parvinder Sagoo, Pharmacist and Online Health Adviser for SimplyMedsOnline, explains: “Drinking coffee as soon as you wake up could interfere with your body's cortisol production which could leave you feeling more stressed and anxious if you dive straight in for a coffee as oppose to a glass of water.”
Drinking water first thing in the morning immediately helps rehydrate the body. Your six to eight hours of sleep is a long period to go without any water consumption. Drinking two or three glasses of water right when you wake up is a good way to rehydrate your body quickly.
The benefits of drinking water on an empty stomach include positive effects for flushing toxins from the body, increasing energy and immunity, reducing weight and increasing metabolism, and preventing headaches and kidney stones. It aids in the cleansing of bowels and improves hair and skin health.
When you drink coffee, the tannins in the brew seep into those pores, leaving deep stains behind. As coffee is acidic, it can also wear the enamel away over time, leading to more stains. Other beverages that contain tooth-staining tannins include black tea and red wine.
Health organisations around the world suggest that most people can safely consume up to 300mg of caffeine a day. Some people are advised to consume less though. The NHS suggests that pregnant women consume no more than 200mg, or 2 cups, of caffeinated coffee a day.
These problems include: The high acidity of coffee can interfere with your hormones and impact the amount of oil your skin produces. Coffee drinks with dairy products increase your risk of developing acne. Dehydration from coffee and other drinks such as soda or alcohol may also cause skin redness or inflammation.
Adenosine is a neurotransmitter that promotes sleepiness, and its levels increase throughout the day. By waiting 90 minutes after waking to consume caffeine, you allow your adenosine levels to rise slightly, making the caffeine more effective at blocking the receptors and keeping you alert.
cortisol production is strongly related to your level of alertness, and it just so happens that cortisol peaks for your 24-hour rhythm between 8 and 9 a.m., on average. Therefore, you are drinking caffeine at a time when you are already approaching your maximal level of alertness naturally.
“After brushing, it is safe to drink water and coffee immediately since the minerals in toothpaste have strengthened, remineralized, and rid the teeth surfaces of bacteria build up,” Dr. Huang shares. “However, for the best taste, you may want to wait 10 minutes to avoid toothpaste-flavored coffee or water.”
Chewing gum helps generate saliva, which in turn can wash away staining acids and bacteria-harboring plaque. It's not a bad idea to pop in a piece of gum after finishing your morning cup; just make sure it's sugarless!
Scientists also say that biologically, our cortisol hormone levels peak between 8 to 9 a.m., noon to 1 p.m., and 5:30 to 6:30 p.m. Therefore, coffee should be consumed between these windows—such as between 9:30 to 11:30 a.m. "I would say that mid-morning or early afternoon is probably the best time to drink coffee," ...
In fact, if you're trying to balance your hormones, caffeine may be a no-go. Research shows that it can increase estrogen levels. While caffeine is known to give you a quick energy boost, it can also disrupt your hormones, particularly estrogen levels.
The American Academy of Pediatrics recommends no caffeinated coffee, tea, soda, sports drinks or other products for children under 12, while adolescents between 12 and 18 should limit their intake to less than 100 milligrams per day — about the size of an old-fashioned cup of coffee.
