Is caffeine an addictive substance? Can caffeine cause any harm to our body when we drink the products of caffeine like cold drinks or coffee or tea?

Hye. Anything in excess can become harmful for the body. Taking 2 cups of tea or coffee is not a problem as long as it's not taken to wake up, replace a snack or suppress appetite. The problem with aerated drinks is not as much as about caffeine but more so about the chemicals and sugars present in them too. So, keep to moderation and avoid excessive intake of either.

Whether soda contains caffeine ? Whether soda is more dangerous than other soft drinks ?Please tell.

Homeopath, Faridabad
Whether soda contains caffeine ?
Whether soda is more dangerous than other soft drinks ?Please tell.
Hi, carbonated water is water into which carbon dioxide gas under pressure has been dissolved. Some of these have additives such as sodium. Most carbonated water is sold in ready to drink bottles as mineral water and carbonated beverages such as soft drinks. Whether homemade or store-bought, soda water may be identical to plain carbonated water or it may contain a small amount of table salt, sodium citrate, sodium bicarbonate, potassium bicarbonate, potassium citrate, potassium sulfate, or disodium phosphate, depending on the bottler. By itself, carbonated water appears to have little impact on health. While carbonated water is somewhat acidic, this acidity is quickly neutralized by saliva. Carbonated water may increase irritable bowel syndrome symptoms of bloating and gas due to the release of carbon dioxide in the digestive tract. There is tentative evidence that carbonated water may help with constipation among people who have had a stroke. Some carbonated waters have added sodium, so they may be an issue for those on low-sodium diets. Carbonated soft drinks such as colas do have health risks. Carbonated colas have a correlation with slightly decreased bone density in older women. Soft drinks are about 100 times more erosive to teeth than plain carbonated water. A soft drink (see terminology for other names) is a drink that typically contains carbonated water, a sweetener, and a natural or artificial flavoring. The over-consumption of sugar-sweetened soft drinks is associated with obesity, type 2 diabetes, dental caries, and low nutrient levels. Many soft drinks contain ingredients that are themselves sources of concern: caffeine is linked to anxiety and sleep disruption when consumed in excess.

Caffeine - Can It Cause Infertility?

Caffeine - Can It Cause Infertility?

Many studies have shown that excessive caffeine intake affects your chances of conceiving by influencing the ovulation, hormone, and the fallopian tubes but the opinions on this issue are divided. However, research on this topic mostly indicates that, though caffeine can give you a kickstart in the morning, it can have quite a reverse effect on your efforts to conceive.

How intake of excessive caffeine reduces your chances of conceiving?
The fallopian tubes are responsible for carrying the eggs from ovaries to the uterus by rhythmic movements and too much caffeine can affect this movement and cause disruption in the journey of the eggs. Moreover, consuming more caffeine has also been associated with baby's growth restriction, miscarriages, and weight issues. It is preferable to get rid of caffeine altogether from your diet when you are trying to conceive but if you are an avid coffee drinker then you might want to cut back or replace your caffeine intake with milk and syrup which is far more healthy and beneficial.

Which foods and beverages do you need to avoid?
There are so many caffeinated foods and beverages, that it is almost impossible to avoid them. But it is better to take note of them so that you can regulate your caffeine intake. Coffee, tea, soft drinks, energy drinks are obvious sources of caffeine as they are supposed to give you energy. Some herbal teas also contain caffeine. Chocolate, ice creams and candies with coffee flavors, over the counter drugs for allergies, cold and headache also contain caffeine so it is important to read the ingredients list before consuming any of them.

To higher your chances of getting pregnant, it is important to cut back on caffeine. Most doctors are of the opinion that exceeding 50 mg of caffeine intake daily can seriously hamper your chances of conceiving. If you wish to discuss about any specific problem, you can consult a Gynaecologist.

Can Too Much Of Caffeine Cause Premature Ejaculation?

It is important for you to both take care of your body and love your body. At times due to certain factors our body does not perform the way we wants it to. There are various phases of sexual activity that include attraction, stimulation, excitement and peak. These stages usually come in close sequence and follow a normal course until the sexual peak ends in sexual orgasm. Yet, this process can be hindered by a condition known as premature ejaculation that many men suffer from. Premature ejaculation happens when a man ejaculates sooner than required or planned, in the process of sexual activity and intercourse. This usually happens within a minute or so of penetration. There are a variety of causes for this, starting from biological to psychological. Read on to know more about these causes.

  1. Erectile Dysfunction: This condition is one where the male patient experiences trouble during sexual encounters and experiences. As per this condition, the patient will have difficulty in mustering up and thereafter, retaining an erection for satisfactory sexual intercourse. This condition can also contribute to premature ejaculation.
  2. Chronic Health Issues: Many male patients who are suffering from chronic health issues are at 
  3. Health risks: Serious risk of developing premature ejaculation in the long run. These health issues range from diabetes to heart disease. Due to these diseases and ailments, the patient may feel considerable stress or even may not be able to ejaculate later in the process of intercourse.
  4. Anxiety: Anxiety is one of the primary reasons for such physical problems that one experiences during sex. These patients may be suffering from anxiety due to their performance in bed, or they may be anxious about a new relationship or partner. This anxiety can lead to a state where the patient is not able to fully enjoy the act of intercourse and ends up ejaculating prematurely.
  5. Relationship problems: Another issue that many male patients suffering from this condition face includes relationship problems. These problems can create trouble in the sex life of the patient due to which sex may not be happening on a frequent or regular basis. Due to this, the ejaculation may also suffer, leading to further stress.
  6. Biological Issues: There are a number of biological problems due to which men may also experience premature ejaculation and other related health issues. Abnormal hormonal levels and an imbalance in the state of one's hormones can lead to this condition. Also, there are instances where the neurotransmitters of the brain enjoy an abnormal level of activity which can lead to an abnormal reflex reaction in the ejaculatory system of the patient. Nerve damage can also lead to this condition.
  7. Thyroid: Male patients suffering from thyroid problems have also reported instances where premature ejaculation becomes a problem. If you wish to discuss about any specific problem, you can consult a Sexologist.
