In the hot season, drinking ice water is “extremely good” but beware of bringing enough diseases into your body-Health and Life

In the hot summer, drinking a glass of ice cold water will help us quench our thirst and bring back a pleasant cool feeling. Bringing immediate benefits, but drinking ice regularly in the hot season will cause our body to encounter many serious problems.

Causing fat accumulation in the body

If you drink ice cold water right after a meal, the cold temperature will solidify the fat from the food you just consumed, making it difficult for the body to break down unwanted fats in the body. No matter how active we are, it is difficult to burn that extra fat.

Slow down your heart rate

Research from Anglia Ruskin University shows that cold water also slows the heart rate, because ice cold water affects and stimulates the vagus nerve – an important part of the body’s autonomic nervous system. When this nervous system is inhibited, your heart rate slows down.

Inhibition of the vagus nerve

When drinking too cold water into the body, it will inhibit the vagus nerve – the nerve of the sympathetic nervous system that regulates the activity of the heart rate. When this nerve is inhibited, it can cause the heart to beat slowly, even increase blood pressure.

Therefore, you should not drink too much cold water often in the summer. To cool off on a summer day, you can drink tap water, green tea, and black bean juice. Along with that, you should eat a lot of potassium-rich vegetables such as gotu kola, tomatoes, jute vegetables, lettuce…

Reduced resistance

Usually ice contains a lot of bacteria and especially ice bought from outside, the quality will not be guaranteed. So when the ice melts in the body, the bacteria will start to attack you, which can cause dangerous diseases and gradually lead to a decline in the body’s resistance.

Damaged teeth

The harmful effects of ice are reflected in the sensitivity of your teeth to decay and at the same time affect the enamel, reducing the resistance of the teeth, thereby causing oral diseases. Drinking ice water can damage tooth enamel, even cracking and chipping due to thermal shock (when the temperature changes suddenly). The habit of chewing ice can also make teeth weak and brittle.

Causes sore throat

Drinking ice water when the weather is hot, the possibility of sore throat and nasal congestion is very high, because cold water will dry the protective mucus layer of the throat mucosa, causing cold burns, causing throat pain and injury. .

Causes constipation

Normally drinking water will help us digest easier, but drinking ice water can cause constipation. Because cold water enters the body, causing food to contract in the intestines, the ability to contract is affected, leading to poor digestion of the stomach and intestines, causing constipation.

Additionally, experts say that cold water and even cold drinks can constrict your blood vessels, thereby restricting digestion. It also interferes with the natural process of absorbing nutrients during digestion.

Reduces energy

Some people think that drinking cold water will make them more refreshing and give them more energy. But in fact, it can bring an instant feeling of comfort, but once inside, we will lose a lot of energy to heat up the cold water we just drank and make the body more tired and lethargic. more sluggish.

Heat shock

People should not drink cold water after exercise. When you exercise, a lot of heat is generated and if you drink cold water right after, the body temperature will change suddenly, affecting the digestive tract which can lead to stomach pain or heat stroke. .

4 cases to be careful when drinking ice water

After eating full or eating hot pot: The food temperature for the fastest absorption by the body is moderate warmth. Cold water will slow down the process of pumping blood to perform the body’s digestive function, leading to a feeling of fullness, even abdominal pain. Especially after eating hot pot, if you use cold drinks, this hot and cold mixture is very harmful to the stomach and intestines.

Immediately after exercise: After exercising and sweating, the blood vessels as well as the pores on the body widen. At this time, you should not be exposed to cold things, which cause a sudden drop in body temperature such as drinking ice water or entering a cold air-conditioned room immediately. Use only cold or lukewarm water just enough to replenish lost water. After your heart rate, temperature, and body are regulated again, wipe away sweat, use cool water to feel more refreshed.

When you have a cold: In addition to not drinking ice when you have a cold, people who are prone to colds should also limit their intake of ice.

During menstruation: This is a sensitive time for women, who hate cold foods and ice cold water is one of them. If used in the “red light” days, women are prone to blocked periods, menstrual pain. Women who often suffer from menstrual pain should also limit drinking ice even outside of their period.
