Human's studies have shown that caffeine increases hormones such as cortisol and epinephrine during resting periods. So drinking coffee actually re-creates stress conditions for the body. 2. The release of too many of these hormones sends our body into a "fight or flight" behavioral mode.
“Drinking caffeine can increase estrogen levels in women, sometimes leading to an estrogen dominant state,” says Odelia Lewis, MD, a medical contributor to ABC News Medical Unit. “Estrogen dominance is associated with premenstrual syndrome, heavy periods, fibrocystic breasts, and even certain breast cancers.
The way caffeine works on your brain is that it inhibits a natural neurotransmitter called adenosine (a naturally calming hormone), which naturally builds up throughout the day, making you feel tired as the day progresses.
Caffeine causes sex hormone imbalances.
Because of its capacity to contribute to HPA axis dysfunction and cortisol dominance, regular caffeine intake can affect the delicate balance of your reproductive hormones, including oestrogen, progesterone, and testosterone.
For most people, caffeine withdrawal symptoms can last two to nine days and you should be feeling fine again no more than two weeks after you stopped using caffeine.
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. Estrogen, on the other hand, is a vital hormone for the female body, responsible for everything from reproductive health to bone strength.
Caffeine consumption is also linked with increases in blood pressure in females (but not males). This makes coffee and caffeinated beverages dangerous stuff if you suffer from existing hormone balances — or if you are concerned about protecting your hormones and your fertility in the future.
Hot flashes, flushes, and night sweats are the most common symptoms of low estrogen. At times, blood rushes to your skin's surface. This can give you a feeling of warmth (hot flash). Your face may look flushed.
Usually, coffee feels good in the short term, but too much of it can backfire. Since coffee inhibits the absorption of adenosine (a hormone that calms the body), it makes you alert and feel awake. It can also increase the production of cortisol, the stress hormone, which can gear you up for the task at hand.
Consuming coffee during periods is also connected to longer, heavier periods and other irregularities, according to a 2014 study published in the Journal of Taibah University Medical Sciences. It also says that habitual use of caffeine needs to be considered as a risk factor for most of the menstrual abnormalities.
Drinking coffee can boost your happy hormones
Coffee contains caffeine, which is a stimulant that can boost mood and energy levels. The caffeine in coffee works by increasing the levels of certain chemicals in the brain, such as dopamine and norepinephrine, which can lead to feelings of happiness and euphoria.
Too much estrogen in the body can also cause many reproductive health conditions, such as painful periods, polyps, polycystic ovary syndrome (PCOS), dense breast tissue, fibroids and increased endometriosis pain.
As estrogen levels drastically change in perimenopause, high levels can cause bloating, breast tenderness, and heavy bleeding. Once these levels become more consistently low, that can cause hot flashes, night sweats, mood changes, changes in fat distribution (new or growing “spare tire”), insomnia, and fatigue.
Some studies on caffeine intake and menopause symptoms have shown that an increased caffeine intake can lead to an increased frequency of hot flushes [8]. However, there is limited data on the quantity and frequency of caffeine consumption and hot flushes.
Among men, consumption of caffeinated coffee increased total testosterone and decreased total and free estradiol. Among women, decaffeinated coffee decreased total and free testosterone and caffeinated coffee decreased total testosterone.
The effects of caffeine on weight are mixed. Under certain circumstances, it may cause weight gain and an increase in belly fat. But if consumed sensibly, it will actually benefit the waistline. Continue reading to discover caffeine's numerous effects on weight management, metabolism, and fat burning.
