1. What water should I not drink in the morning?
1, a long-standing boiled water
If boiled water is left for a long time, the nitrogen-containing organic matter in it will be continuously decomposed into nitrite. Especially boiled water stored for a long time will inevitably be contaminated by bacteria. At this time, the decomposition of nitrogen-containing organic matter will be accelerated and more nitrite will be formed. After drinking such water, nitrite will combine with hemoglobin and affect the oxygen transmission function of blood.
Therefore, the boiling water in thermos bottles for many days, the residual water that has been boiled for many times, and the water that has been boiled for a long time on the stove have all changed in composition and cannot be drunk. You should drink boiled water for no more than 24 hours. In addition, bottled and barreled purified water and mineral water should not be stored for too long. Bottled or barreled purified water and mineral water should not be drunk for more than 3 days.
2. Salt water
Some people think that drinking light salt water is good for health, so drinking light salt water in the morning is really wrong. Drinking light salt water is good for your health. It is necessary to replenish water after sweating in summer, but replenishing water in the morning is not only useless, but also a wrong practice that harms your health.
According to physiological research, people don't drink water during the whole night's sleep, but breathing, perspiration and urination are all going on, and these physiological activities consume a lot of water. When I got up in the morning, my blood had become concentrated. At this time, if you drink a certain amount of boiled water, you can quickly dilute the blood and correct hypertonic dehydration at night. Drinking salty boiled water will aggravate hypertonic dehydration and make people thirsty. What's more, the morning is the first peak of human blood pressure rise. Drinking salt and boiled water will raise blood pressure and endanger health.
Step 3 drink
It is best not to drink juice, cola, soda, coffee, milk and other drinks in the first glass of water in the morning. Most carbonated drinks such as soda and cola contain citric acid, which will accelerate the excretion of calcium during metabolism and reduce the content of calcium in blood. Long-term drinking will lead to calcium deficiency. Other drinks are good for urination. Drinking water in the morning can not only effectively replenish the water that the body lacks, but also increase the collective demand for water, resulting in water shortage in the body.
Fruit juice, milk and coffee should not be used as the first cup of drinks in the morning, because these substances can not provide the most needed water for the body at this time, but also make the body digest and absorb the gastrointestinal tract in a state of water shortage, which is not conducive to health.
4. Tap water
Some people are used to getting up in the morning, turning on the tap and drinking a glass of tap water, which is not right. The tap water that has been stopped all night and the tap water in the water pipe are still. This water, the metal pipe wall and metal cavity of the faucet will produce hydration reaction, forming metal polluted water, and the residual microorganisms in tap water will also multiply in large quantities. This kind of water contains a lot of substances harmful to human body, and may also contain Legionella, an acute respiratory infectious disease that threatens human health. So when you turn on the tap in the morning, the tap water that comes out at first is inedible stagnant water. People who have this habit should correct it immediately so as not to damage their health.
Second, the precautions for getting up in the morning
1, avoid eating immediately after waking up.
After a night's sleep, my stomach is still in a state of "half dream and half awake" in the morning, and it takes ten minutes to half an hour to wake up. Moreover, saliva and gastric juice are secreted less in the morning. If you eat it right away, especially some indigestible foods (such as meat), it will easily lead to indigestion. Tan, director of the Nutrition Department of Tianjin First Central Hospital, suggested that it is best to drink a glass of water after getting up in the morning and eat later. This glass of water can not only replenish the water lost during sleep, increase the secretion of digestive juice, but also promote blood circulation and prevent cardiovascular accidents. It should be noted that this glass of water is preferably boiled water with the same room temperature. You can drink warm water in winter, but fruit juice, coffee, milk, carbonated drinks and light salt water are not suitable. Also, don't drink too much water in the morning. A sip is more beneficial to your health.
2. Avoid strenuous exercise after waking up.
With plenty of time, moderate exercise in the morning has many benefits to health. However, some people start strenuous exercise immediately after getting up in the morning, such as sit-ups, running and square dancing. Others ran all the way to catch the bus to work, exhausted and panting. Zhou Yingchun reminded that strenuous exercise in the morning can stimulate excessive excitement of sympathetic nerve, disturb autonomic nerve rhythm, make people nervous and anxious all day, and middle-aged and elderly people are prone to cardiovascular and cerebrovascular emergencies such as myocardial infarction. She suggested that office workers should get the clothes and things they want to wear the next day the night before, so that they don't have to hurry to pack up. Try to take your time on the road, don't walk fast or trot. Exercise early, it is better to do "health exercises". The specific method is: lie flat and relax, cross your fingers, put your palms up on your head, straighten and alternately hook your toes, and turn left and right at the same time; Then rub the chest and ribs with your palm from top to bottom in turn; Then, massage the periumbilical points clockwise with your palm for 50 times; Finally, pat the outside of both lower limbs with both hands and half fists, and feel the skin on the outside of both lower limbs warm. If you want to get up and exercise, it is recommended to take gentle and gentle exercise, such as walking, Tai Ji Chuan and Baduanjin.
Don't get up without opening the curtain.
Many people are too lazy to open the curtains after getting up, but Zhou Yingchun pointed out that in order to wake up from sleep quickly and thoroughly, it is best to open the curtains first, let the sun shine in and give a signal to the biological clock. At this time, the body will stop secreting drowsy melatonin and increase the level of serotonin (a hormone that brings pleasure and happiness) in the brain. Open the window conveniently, stand by and open the window for a while, take a few breaths of fresh air, and provide enough oxygen for the brain, which can accelerate the brain to wake up. Opening light in the bedroom in rainy days can achieve the same effect.
4. Avoid urinating immediately after waking up.
Drinking too much water at night, or having frequent urination and urgency symptoms, is often awakened in the early morning. If you get up in a hurry to go to the toilet, you will often get dizzy. Professor Yang Li of Chinese Academy of Traditional Chinese Medicine pointed out that during sleep, the metabolic level of human body drops, the heartbeat slows down, blood pressure drops, and various physiological functions operate slowly. At this time, suddenly going to the toilet, the bladder emptying is fast, which is easy to induce hypotension, causing short-term blood supply to the brain, leading to voiding syncope. In the cold winter, the morning is the "devil time" for sudden myocardial infarction and stroke. Middle-aged and elderly people go to the toilet immediately after waking up, which is also easy to induce cardiovascular and cerebrovascular diseases. So, even if you have to pee urgently, don't get up and run to the toilet immediately, but get up slowly, sit by the bed for a few minutes, and then walk slowly to the toilet.
Don't get up immediately after waking up.
Many people wake up in the morning and get up in a hurry, but they are "knocked down" by a sense of dizziness. Professor Zhou Yingchun, the chief physician of the Department of Traditional Chinese Medicine in the Southern Hospital of Southern Medical University, told the reporter of Life Times that it takes a process from inhibition to excitement after waking up. If you get up immediately, get dressed and wash, your body will not adapt and your blood flow will be slow. If oxygen cannot be delivered to the brain in time, dizziness, dizziness and other discomforts are prone to occur, and cardiovascular and cerebrovascular accidents are also prone to middle-aged and elderly people. Zhou Yingchun suggested not to get up in a hurry after waking up. Old people can do the following activities on their backs: first, rub their hands, dry their faces several times, and then massage their temples, back of their heads and neck in turn for 20 times; Secondly, make a fist with both hands half-clenched, lightly punch the back 10 times, and then punch the sides of thighs and the outside of calves; Finally, kick the soles of your feet alternately, and then rub them to make them feel warm.
6. Don't fold the quilt immediately after waking up.
Many parents educate their children to form the "good habit" of folding quilts immediately after getting up. However, a study by Kingston University in England shows that it is good for your physical and mental health not to fold the quilt immediately after getting up. Dr. Pu Reithler, the chief scientist of this study, pointed out that even in a very tidy bedroom, there are at least 6.5438+0.5 million mites in the bedding on each bed. Because indoor dust mites are not easy to survive in dry and exposed environment, the folded quilt can easily preserve the temperature and sweat of human body, thus creating living conditions for dust mites. In addition, people will emit a lot of waste gas during a night's sleep, including carbon dioxide and other chemicals 149, and about 150 substances evaporated from sweat, which will be adsorbed on the quilt. Cover the quilt immediately after getting up. These substances are not easy to disperse, leading to the accumulation of harmful substances and the proliferation of microorganisms, which not only changes the properties of quilt fibers, but also is reabsorbed by the human body at night, which is harmful to health. So don't fold the quilt and make the bed immediately after getting up, but turn the quilt over, let the quilt face outwards, and open the doors and windows to ventilate, and then fold the quilt after washing.
7. Avoid staying in bed after waking up.
Many office workers are used to lying in bed during holidays. However, most bedridden people have this feeling: they have been lying for a long time, or they feel heavy limbs, listless and dizzy, and have no spirit to get up early on weekdays. Zhou Yingchun pointed out that lying down for a long time is harmful to qi, and sleeping late is not conducive to the declaration of human yang, leading to poor qi movement and easy stagnation. Some people get up and wash in a hurry after the alarm clock rings several times, which will make the sympathetic nerves excessively excited and the autonomic nerves disordered, which will easily make people feel irritable. According to a study by British Psychological Association, people who get up early are healthier and happier than those who get up late. Therefore, we should form a good habit of staying in bed at any time. Go to bed early on weekdays, try to get up early for a while, and set aside a glass of water and breakfast. Don't stay in bed on holidays, go to the morning market, buy some fresh fruits and vegetables and treat yourself with breakfast when you come back. It is better to take part in aerobic exercise outdoors than to enjoy it in bed.
8. Avoid working immediately after waking up.
Some people have a very tight task, and when they wake up, they throw themselves into the intense work. But at this time, insufficient blood supply to the brain not only leads to low work efficiency, but also easily leads to fatigue. Zhou Yingchun suggested that no matter how busy you are at work, you'd better lie in bed and think clearly about your plan for the day after waking up, so that your resting muscles and blood can "wake up" slowly. Then get up slowly and stretch. You can also do a little stretching exercise in bed to relax your whole body muscles: straighten your left leg, bend your right leg, open your arms horizontally, and twist your upper body rhythmically for 20 times; Then lie on your back, curl up, put your arms around your knees, stand still for a while, and then slowly roll up and down for 20 times.
