1, does ice water accelerate body metabolism?
After exercise, a glass of cold ice water can not only effectively reduce fever, but also make people feel refreshed after drinking! However, in addition to quenching thirst, it has recently been circulated on the Internet that "moderately drinking ice water below body temperature will make the body consume more calories to raise the temperature and keep the body temperature constant. Therefore, drinking ice water is a small coup to help improve metabolism and help lose weight. " Is drinking ice water really so magical? And listen to what doctors and nutritionists of professional Chinese medicine say!
1, it is very important to protect health and drink water in moderation! Regulating body temperature and eliminating waste all depend on water.
Drinking water in moderation is very important for human health! Water not only accounts for 70% of human body composition, but also plays a role in regulating body temperature, transporting nutrition and eliminating waste. Therefore, drinking enough water every day is one of the keys to maintain the normal operation of physiological functions.
As for how much water adults should drink every day to meet their needs, it is generally suggested that healthy adults should consume at least 1500c.c and at most 3500c.c, and it is not appropriate to take a short-term swig, but to sip moderately to avoid the metabolic burden of the kidneys caused by sudden excessive drinking.
2. Drinking ice water can improve metabolic rate? Most studies still can't help to judge.
2. The influence of water temperature on the body.
Does drinking ice water in moderation really improve metabolic rate and help you lose weight?
Dr. Chen Junru-zhong and nutritionist Jiang Miaoyun wrote in the joint book "A Good Way to Lose Weight _: You can't lose weight. It turns out that there is something wrong with your immune system! It is mentioned in the book that according to previous research data, in 2006, Swiss scientist Brown said that drinking steamed water at room temperature will not increase energy consumption, while drinking cold water at 3℃ will increase energy consumption by 4.5% (15kj, 3.57 kcal), which is far lower than the theoretical value of heating water to body temperature (70kj, 65437 kcal).
In addition, in 2007, German researcher Boschmann pointed out that the stimulation of water temperature cannot be used to explain the cardiovascular regulation and metabolic response caused by drinking water. Therefore, based on the above point of view, it is impossible to know whether drinking warm water and ice water will help to lose weight.
3. Cold drinks can easily lead to obesity.
Decreased metabolic rate of iced drinks can easily lead to obesity.
In addition, Tan, a Singaporean scholar on 20 15, also mentioned in his comments on fluid temperature and athletes' endurance, and Siegel, an Australian scholar, pointed out in his study on 20 10 that drinking cold water at 4℃ and smoothies at-10℃ would reduce the athletes' anal temperature by 0.3℃ and 0.6℃ respectively. In terms of metabolic rate, the representative metabolic rate decreased by 4.2% and 8.4% respectively. If this value is converted into kcal, the metabolic rate of adult women will be reduced by 50 kcal and 100 kcal respectively; The metabolic rate of adult males will decrease by about 63 calories and 126 calories respectively.
This study is aimed at athletes whose body temperature rises during exercise. Their body temperature is higher than the core temperature during exercise, so low temperature will not affect their metabolism, but it will help improve their endurance during exercise. However, if we consider that ordinary people do not exercise, such a decline in metabolic rate is not a good thing, and may even lead to obesity because they often drink cold drinks or ice products.
4. Women should drink less cold drinks.
Prevent qi and blood stasis from brewing gynecological diseases! Chinese medicine drinks warm water better than ice water.
Women with cold constitution and insufficient qi and blood may damage the spleen and stomach if they eat ice products and drink cold drinks again, so that the cold will block the relevant meridians and affect the circulation of qi and blood. The uterus, in particular, is the organ that needs qi and blood most in the body. Once qi and blood are not smooth, it is easy to cause gynecological diseases.
As for Chinese medicine, drinking warm water can reduce the burden on the body! This prevents the body from consuming yang, and the ice water after drinking is heated to a constant temperature of 37℃ with the body temperature. Especially for women with cold constitution and insufficient qi and blood, if they eat ice products and drink cold drinks again, they may damage the spleen and stomach, make the cold block the relevant meridians and affect the circulation of qi and blood. The uterus, in particular, is the organ that needs qi and blood most in the body. Once qi and blood are not smooth, it is easy to cause gynecological diseases.
Therefore, it is suggested that friends who need to lose weight should develop regular exercise habits and improve blood circulation, instead of counting on drinking ice water to promote metabolism and help lose weight. At the same time, a normal work and rest and a balanced diet are the only ways to stay healthy and have a slim figure!
5. Don't drink ice water after exercise.
After strenuous exercise, your whole body blood circulation is accelerated, so it is important to concentrate on supplying muscles and brain. If you drink ice water at this time, your body temperature will soon drop below normal, that is, there is no gradient. This will affect your blood vessels and even cause damage. At the same time, it will give your stomach a strong impact, cause stomach wall spasm and cause stomach pain. So don't drink ice water.
