Caffeine is the most common natural stimulant found in tea, coffee and cocoa plants. Billions of people start their day and rely on caffeine to survive night shifts and slumps in the afternoon. It works by stimulating the brain and central nervous system, maintaining attention and reducing the onset of fatigue. On a chilly morning, nothing is more soothing than hot tea with a soothing blanket. For most people, the intake of these caffeinated beverages increases during the winter because they believe they provide warmth to overcome the cold. But is that really the case? Is there any reason to avoid caffeinated drinks? Let’s check!
How caffeine works
Caffeine is considered safe, but drinking too much raises some concerns. When you drink a caffeinated drink, the intestines absorb it very quickly and send it into the bloodstream. From there, when it reaches the brain, it begins to block the effects of a neurotransmitter called adenosine. Adenosine relaxes your brain and makes you tired. Therefore, caffeine wakes up and stays vigilant by blocking its receptors. However, awakening also involves anxiety. At the same time, caffeine also stimulates our stress or “fight or flight” hormones.
Reasons to avoid caffeinated drinks during the winter
- dehydration: During the winter, most people have less thirst and automatically reduce their fluid intake. All caffeinated beverages are diuretics and tend to wash water from the body through the urine, so they lack not only water, but also the vitamins and minerals needed for the smooth functioning of the body.
- Amplified heart rate and blood pressure: Winter is not a good time for people with heart disease or high blood pressure. It is always advisable to keep away from low temperatures as it can constrict blood vessels and cause high blood pressure. Caffeine, a stimulant, also raises heart rate and blood pressure. Therefore, it can be more difficult for such people.
- Empty calories: Most caffeinated beverages contain sugar, which can be lethargic after a while as it not only contains empty calories, but also causes the sugar to crash later.
- Effects on digestion: Caffeine, a stimulant, increases muscle contraction that promotes intestinal motility or gastrointestinal contents. This may be the reason why you want to drink tea or coffee before and after a heavy meal. But this is not really good. This is because it reduces the amount of time food stays in each part of the digestive system and prevents it from completely absorbing nutrients. In fact, too much can cause diarrhea and then dehydration.
- Pregnancy and breastfeeding: Caffeine can easily pass through the placenta and reach breast milk. Therefore, women who drink caffeinated drinks may need to limit their intake to avoid the risk of miscarriage and low birth weight.
- Interaction with drugs: Our body usually flushes caffeine within 6-8 hours, but while in the system it can react with your medications and supplements, causing malabsorption and side effects.
- Suppress appetite: This can be good or bad for all weight watchers. Studies show that caffeine acts as an appetite suppressant, but increases plasma levels of PYY and leptin (anorexia hormone). It may make you eat less calories, but with less food, as well as less nutrition. Be aware that you overdose caffeine as our body needs more nutrition to maintain immunity.
