What is Caffeine?
- It is proven that a cup of hot coffee can help uplift your senses and refresh you. This quality of coffee can be attributed to the presence of caffeine, which is a central nervous stimulant.
- Caffeine is basically a bitter white crystalline alkaloid. It is a stimulant drug that is found in varying amounts in the seeds, leaves and fruits of some plants.
- Caffeine is most commonly consumed in the form of tea, coffee, soft drinks and energy drinks.
- It is widely consumed in the form of infusions extracted from seeds of the coffee plant and leaves of the tea bush.
- Other sources include edibles containing products derived from the kola nut.
- Caffeine is often considered a harmful drug as it can be addictive. Taking it in the right dose can have positive effects on your health.
- Using caffeine causes an improvement in sports performance, increases alertness and reduces fatigue.
- It can temporarily ward off drowsiness and lift up your mood. Hence, unlike other psychoactive substances, caffeine is legal and unregulated in almost all parts of the world.
Benefits Of Caffeine For Health
A question that everybody has in mind is whether caffeine is good for health. The amount of caffeine contained in two to four cups of coffee a day is not harmful. However, excess caffeine intake can make you feel restless, irritable and anxious. Some people are sensitive to caffeine, and they need to restrict their intake. Taking caffeine in the right doses can provide the following health benefits.
1. Good For Liver
Caffeine, when taken in the form of caffeine enema, detoxifies your liver and cleanses the colon. A study at Duke University has proved that caffeine may reduce fatty liver in those suffering from non-alcohol related fatty liver disease.
2. Reduces The Risk Of Diabetes
Research says that drinking 5 cups of coffee a day can reduce the risk of developing diabetes. This is primarily because of the presence of high level of disease-fighting antioxidants. Drinking sugar-free coffee daily can make you less likely to suffer from type 2 diabetes.
3. Sharpens Your Brain
Caffeine is good for your brain. It causes the release of dopamine, the brain chemical that stimulates the area of gray matter. This again is responsible for alertness, problem-solving and pressure, thus making your brain active and sharper. No wonder we need a cup of strong coffee first thing in the morning. It helps us stay alert all day.
In fact, research at Harvard has proven that people who drink four cups of caffeinated drink are half as likely to suffer from Parkinson’s disease in comparison to others. This is primarily because caffeine keeps dopamine molecules active. It also blocks adenosine that may slow down the buildup of amyloid-beta, a toxic brain plaque that is associated with Alzheimer’s disease.
4. Cardiovascular Health
A few cups of coffee per day can gift you with a healthy heart! Wondering how? Well, caffeine constricts your arteries by infiltrating the receptors that line the blood vessel walls. This causes your blood pressure to rise. However, this is a problem with non-habitual drinkers. The effect on blood pressure tends to be much smaller on habitual coffee drinkers as their bodies are somewhat tolerant to its effects.
In fact, research at Brooklyn College has found that men who consumed 4 cups of caffeinated beverage daily are less likely to suffer from heart disease than those who never took a sip. Drinking coffee has been found to reduce the risk of stroke by 22%. So don’t give up on caffeine just like that, it has a lot to offer!
5. Aids In Weight Loss
Drinking caffeinated drinks can help in weight loss. Regular drinkers often report a decrease in appetite, resulting in weight loss. Just make sure you don’t go overboard with it! 300-400 milligrams of caffeine in any form (cola, tea, or coffee) is enough.
6. Eye Health
Caffeine has been associated with eye health benefits recently. Being a powerful neuroprotectant, caffeine is known to reduce the chances of hypoxia (deprivation of oxygen) in the retina, thus preventing retinal degen
7. Anti-Cancer Properties
Caffeine can reduce the risk of developing cancer. It also delays the onset of common cancer.
Several published studies have focussed on caffeine’s effect on cancerous cells. And here we aren’t talking about one or two cups daily; all these studies focus on four cups of caffeine on a daily basis to cut cancer risk.
Studies reveal that having at least 5 cups of caffeinated drinks can reduce the risk of oral cancer by 39%, brain cancer by 40%, colon cancer by 42%, breast cancer by 49%, and endometrial cancer by 19%.
8. Improves Muscle Performance And Stamina
Research has proven that consuming 140 to 400 mg of caffeine 30 to 60 minutes before exercising can improve both speed and endurance. What a way to make your workout easier!
Caffeine slightly increases your heart and breathing rate by stimulating your nervous system. This prepares your body for peak performance. It also facilitates muscle contraction blocking the adenosine receptors attached to muscle fibers. This triggers electrical activity that prompts bigger bursts of calcium.
Additionally, caffeine, when mixed with carbs, can replenish muscle glycogen concentrations faster after exercise. Hence, caffeine is often used in energy drinks to increase stamina.
9. Treatment Of Migraine And Headaches
A night of binge drinking (alcohol) can lead to an uncontrollable headache the day after. Yup, I’m talking about the inconsiderate and painful hangover. A cup of strong black coffee might help beat that cruel pain! The strong neuroprotective effects of caffeine are helpful to hike the effectiveness of gastrointestinal uptake of painkillers. Hence, it is beneficial for patients with migraine and headache medications.
10. Improves Memory
Caffeine increases the level of a neurotransmitter called acetylcholine. This is associated with attention, concentration, learning and memory. Hence, it has a positive effect on memory and cognitive function. All in all, caffeine is excellent for our brain health!
Benefits Of Caffeine For Skin
Besides boosting your mood, caffeine can improve your skin as well. There is a reason cosmetic companies have started incorporating caffeine in their range of skincare products. Read on to know how:
11. Fights Free Radicals
Free radicals are responsible for causing premature skin aging. This results in the appearance of wrinkles, fine lines, and loss of elasticity. Yeah, the feared three signs of aging!
But caffeine can help. The antioxidants contained in caffeine can attack these free radicals and eliminate them. This will improve the overall appearance of your skin. For this reason, caffeine is widely used in anti-ageing day and night creams in conjunction with retinol.
12. Soothes Inflammation
Caffeine possesses anti-inflammatory properties that make it useful in reducing inflammation and redness in your skin. Using caffeine in skincare products can reduce and prevent inflammation and redness and give you beautiful, even skin tone.
13. Treatment of Under Eye Dark Circles
Dark circles can be caused by various factors such as dehydration, allergies, lack of sleep or genetics. Even though caffeine cannot cure hereditary dark circles, its anti-inflammatory properties make it beneficial in reducing puffiness and inflammation associated with dark circles. Caffeine also reduces the accumulation of blood under your eyes which contribute to dark shadows.
You don’t have to go places in search of caffeine. Used tea bags would do too. Tea leaves contain caffeine. So you can put moist tea bags under your eyes for 5 minutes to reduce dark circles and puffiness without spending too much.
14. Reduces Cellulite
Caffeine present in skin care products can dehydrate fatty cells. This results in the water disappearing from the surface of your skin. This minimizes the appearance of cellulite, thus providing you with a smoother skin.
Research at the University of Sao Paulo has proven that the application of skin cream containing caffeine reduced the size of cellulite fat cells by 17%. A number of anti-cellulite creams are available that can decrease the appearance of cellulite. Another way to use caffeine is to add ground or instant coffee to regular body scrub at home.
15. Treatment Of Rosaceae
Caffeine constricts blood vessels to reduce redness. This makes it an ideal treatment for facial flushing and rosaceae. When applied topically, caffeine works as a diuretic, aids in circulation and is also a powerful antioxidant. Thus, it has the ability to calm irritated and reddened skin caused by sun damage and rosaceae.
16. Repairs UV Damage
Studies have indicated that caffeine may also repair the skin damage caused by exposure to UV rays. It is considered a stronger antioxidant than the polyphenols contained in green tea. In fact, it is among the best and strongest antioxidants to combat UV damage.
17. Tightens Skin
Another added benefit of caffeine is that its topical use can tighten fine lines and smooth puffy skin. Caffeine used in creams is absorbed by your skin to firm and tighten its appearance. It also inhibits the growth of skin cancer cells. Beauty products often include caffeine as it can provide you with a flawless appearance.
Benefits Of Caffeine For Hair
The length and quality of your hair depend on the health of your hair follicles and hair growth cycle. Caffeine stimulates not only your body and mind, but also your hair roots. It is often used as an ingredient in shampoos and other hair care products to improve hair growth and structure. It has the following hair benefits.
18. Treatment Of Hair Loss
Men often experience hair loss due to the effects of the male hormone dihydrotestosterone (DHT) which affects susceptible hair follicles. Consequently, these follicles become smaller and finally disappear, causing baldness. This process, known as miniaturization of the hair follicles, adversely affects the growth phases of hair.
Caffeine, when applied topically, penetrates into the hair roots and stimulates them. Besides preventing male baldness and hair loss, it stimulates the hair roots in the scalps of women and triggers stronger hair growth.
For caffeine to be effective, allow the caffeine-containing shampoo to stay on your scalp for two minutes so that it can penetrate the hair roots.
19. Stimulates Hair Growth
Caffeine is considered a stimulant for hair follicles. Research by the International Journal of Dermatology indicated that topical treatment with caffeine resulted in the increase in average growth of hair follicles by around 46%. It also extended its life cycle by 33%. This is because caffeine can block the effect of DHT, which damages the hair follicles and is responsible for causing male pattern baldness.
20. Makes Hair Manageable
Besides strengthening the hair shaft, caffeine products add natural shine to your hair and make them more manageable.
Caffeine can provide various benefits for your skin, hair and health. However, this is only possible with the right dosage of caffeine. Excessive intake of caffeine has been reported to cause adverse effects on your health. Moreover, some individuals are sensitive to caffeine, and they are required to restrict its consumption or completely avoid it.
Increased consumption can also cause dependence due to increased tolerance, and you require greater amounts of caffeine to obtain the same stimulatory benefits. Given below are the negative effects associated with excess consumption of caffeine.
