When It’s not your cup of Tea?
Many of my friends are addicted to tea, according to them having a cup of tea always feels us rejuvenating. Usually, it is consumed during our breaks and gives a feeling of freshness and instant energy. In India it’s very common to offer a cup of tea to any guest anytime even in summer and is supposed to be a good gesture of welcoming anyone.
However, I am going to tell you all about tea which you must know before having a sip.
Unhealthy effects of tea:
So the very first question is why we should avoid tea? You will find your answer in below quick points. Heavy consumption of tea can cause-
- Addiction: The caffeine in the tea is responsible for the addiction. Caffeine also causes anxiety and restlessness. Caffeine is an Adenosine antagonist (a substance which blocks or inhibits the biological response of another), so indirectly it affects release of some neurotransmitters like dopamine, serotonin etc. These neuro-chemicals give us a feeling of reward which our brain wants to repeat again and again, and my dear friend, that is nothing but addiction.
- Dehydration and Bloating: Excess caffeine and L-Theanine consumption can lead to reduced absorption of water which turns into dehydration. Dehydration leads to water retention which causes bloating.
- Insomnia: This is very well known effect of tea and coffee. Sometimes it’s taken for the purpose of late night working or to avoid sleep. It causes Insomnia because caffeine stops signals for relaxation of smooth muscles by binding to adenosine receptor.
- Adenosine is a neurotransmitter that helps in sleeping by binding to its receptor (A2A) and causes vascular smooth muscle relaxation which leads to vasodilation. But caffeine, which has similar structure like adenosine, binds to adenosine receptors and prevents adenosine to bind there which stops us to sleep.
- Caffeine also stimulates our Central Nervous System (CNS) which alert our brain and not allow it to sleep.
- Diuresis: It’s a process in which body produces more urine. It makes you dehydrated when you lose too much sodium and water from the body. Dehydration causes a number of dysfunction in the body like food absorption etc. These effects can be avoided if caffeine consumption is less than 500 mg (around 3-5 cup).
Facts you should know:
I would like to mention that if you are buying a cup of tea outside from a stall or road side vendor then you should know about below terms, which can save you from harmful effects-
Leaching Effect: If we are outside, we often drink tea or coffee in a plastic or disposable cup. These are made of polyethylene, wax coating or harmful chemicals (can be carcinogenic also). These chemicals percolate or leak into hot drinks in a very small but dangerous amount after pouring boiling liquid and keeping it for some time. This effect is known as leaching effect of chemicals when heated up.
Wax in paper cups: Paraffin wax used as a thin coating inside the cup to uphold the durability in paper cups. It prevent leaking and soaking of hot liquids. Human body can discard a little amount of wax. However, large amount of wax accumulate by long term use of these cups may lead to intestinal obstruction and stomach disorders.
Glasses not washed well: The tea glasses not properly washed is responsible for germs and bacteria transfer from one to another. Natural cleaners, baking soda, vinegar and lemon are good to clean glasses and hot water would be good to use with natural cleaners. After washing, the glass needs to be dry properly.
So, now the very important thing comes up.
How many cups of tea a person should consume in a day?
Of course, we will measure it with cup size. As per health and nutrition specialists, we should use one or two cup of tea in a day. We should prefer in our own well washed cup for good health.
Excess use of caffeine can lead to increased heart rate, excessive urination, anxiety, sleep disorders and other metabolic disorders.
Pregnant women should avoid too much consumption of caffeine because it contains tannins, which can cause underweight baby and also decrease the absorption of folic acid and vitamins that helps to prevent birth defects.
- Do not drink more than 2 cups of Tea or coffee in a day.
- Avoid having Tea from road side stalls if they does not look hygienic.
- Try to use your own tea cup made up of glass, ceramic or stainless steel to avoid germs and bacteria
