Summer cold is stubborn and can cause respiratory disorders like prolonged cough, pneumonia. Summer cold is often accompanied with diarrhea and vomit, and we also sweat a lot in summer, so it can cause dehydration.
The temperature difference between the indoor and outdoor is extreme so that the immune is weakened.
Which is better to prevent summer cold, coffee or green tea?
Green tea is better to prevent summer cold.
Catechin contained in green tea attaches to viruses and prevents them from attaching to the mucus membrane.
To make tasty green tea, the temperature of water should be 70-80 degrees C (158-176 degrees F), but to activate immune cells, the water to make green tea should be cold because more catechin can be extracted.
To prevent summer cold, about 500 cc (16.9 FL OZ) of green tea a day is recommended.
How about coffee?
Caffeine contained in coffee has the effect to widen the bronchial tube, so when you have cough, it is good to drink coffee.
