In summer, we drink a lot of water without sweating in an airconditioned room so that excess water is easily accumulated in the body, but we have to be careful about edema that could be a sign of serious diseases.
Edema is the condition that when you press the skin with your finger, the water where is pressed is lost and a dimple is retained for about 10 seconds, while fat is the condition that the pressed area returns very quickly.
Edema caused by normal excess water can be improved by sweating a lot by taking a relaxing bath or exercises.
But if edema is not improved by sweating, there is a possibility of kidney diseases.
When you have kidney diseases, water can be discharged from your body and is accumulated in your body, resulting in edema of the whole body.
Edema in the leg in the morning (Fig. 1) and edema in the face in the evening (Fig. 2) are dangerous.
Edema in the leg in the evening is okay because water tends to be accumulate in the leg that is locate in the lower part of the body during the daytime.
But if you have edema in the leg in the morning, it could be caused by kidney diseases because the leg is not located in the lower part of the body while sleeping. Excessive water retention could be caused by some problems in the kidney.
On the contrary, edema in the face in the evening means that there is a possibility that water could be discharged sufficiently from the kidney as urine.
One of the causes of wrinkles is UV. The stratum corneum gets thicker to block UV. The thickened stratum corneum gets dry and becomes wrinkles.
But if you avoid UV too much, there is a possibility that the bone could be weakened. Our body makes the bone from vitamin D and calcium. Vitamin D is made by soaking in the sun. That is why if you avoid the sun light, you can’t make the bone in your body.
You can prevent wrinkles and spots and also protect the bone by absorbing UV from the palms of your hands because the palms don’t have melanin pigments that block the UV so that vitamin D can be made efficiently in a short time. Sufficient UV can be absorbed by soaking your palms in the sun for 15 minutes a day.
Wrinkles that could be a sign of dangerous diseases
Wrinkles made in the ear lobe could be a sign of heart diseases (Fig. 1).
The ear lobe doesn’t have many blood vessels so that the ear lobe is easily affected by hardening of the artery (arteriosclerosis) and wrinkles are made by poor blood circulation due to hardening of the artery. The ear lobe is one of rare spots in our body where we can check the condition of our blood vessel.
It is said that wrinkles on the forehead are also made by hardening of the artery, but they are made by UV as well, so the ear lobe that is not easily affected by UV is more useful to check the condition of the blood vessel.
According to a survey conducted on 108 people whose ages were 54-74 year old for 8 years in Chicago University, people who had wrinkles in the ear lobe tripled the risk of heart diseases.
Eating blue back fishes is recommended to prevent hardening of the artery because EPA contained in blue back fishes improves the blood flow and helps prevent hardening of the artery.

Which is better to prevent heat stroke, coffee or green tea?
Green tea is good to prevent heat stroke.
One of the causes of heat stroke is that the water in the body is lost by the raise of the body temperature.
According to a recent research, when drinking green tea, the amount of sweat was more than when drinking water in the heat, resulting in suppressing the raise of the body temperature.
However, barley tea is recommended to prevent heat stroke because barley tea is rich in minerals and doesn’t contain caffeine that promotes urination, so you can drink barley tea as much as you like.
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.
Damage to the skin
Which lowers the damage to the skin due to UV by about 25 %, drinking coffee or green tea?
According to a research in University Witten/Herdecke, Germany, drinking green tea lowers the damage to the skin due to UV by 25 %.
Spots and wrinkles are caused by active oxygen due to UV, but catechin contained in green tea removes active oxygen.
Catechin is a type of polyphenol, which is a substance protecting the plants from UV so that antioxidant action is expected.
Green tea contain vitamin C. 3 cups of green tea contains as much vitamin C as a piece of lemon.
Which is better to prevent the damage to the skin, drinking green tea before going out or after returning home?
Drinking green tea before going out is better to prevent the damage to the skin.
This is the same as you apply sunscreen before going out.
Which can make fat-burning amount about double, drinking 3 cups of coffee or green tea a day?
Drinking 3 cups of coffee a day makes fat-burning amount about double.
Chlorogenic acid contained in coffee suppresses the absorption of sugar and promotes the metabolism of fat.
Caffeine activates a type of enzyme called Lipase, which breaks down fat.
The effect of these two substances promotes fat-burning amount.
Which increases fat-burning amount, drinking iced coffee before exercise or after exercise?
Drinking iced coffee before exercise can be expected to increase fat-burning amount.
Chlorogenic acid and caffeine start to show the effect about 30 minutes after drinking coffee and the effect reaches a peak in 3 hours. That is why drinking coffee before exercise is more effective to burn fat.
How about green tea?
According to a research in UCLA, the metabolism of rats that were given green tea extract increased and the intestinal bacteria that gain weight turned into the ones that lose weight.
Which lowers the risk of stroke by 20 %, drinking a cup of Coffee or Green Tea every day?
If you feel dizzy when you are outside, you feel tingling sensation in the one side of your body or you can’t speak fluently, these symptoms can be a sign of stroke caused by the heat in summer.
Drinking a cup of coffee every day lowers the risk of stroke by 20 %.
When we sweat, the amount of water in the blood vessel decreases, the blood flow becomes bad and the blood vessel is raptured or blocked, resulting in stroke.
Caffeine contained in coffee widens the blood vessel and improves the blood flow.
Caffeine prevents the blockage of the blood vessel by promoting the metabolism of fat and other substances in the blood flow.
But taking large amount of caffeine at once contracts the blood vessel or can put a strain on the heart.
According to a research, drinking 3-4 cups of coffee a day lowered the risk of heart diseases, but drinking more than that didn’t show any effect, drinking 3-4 cups of coffee a day is the best for our blood vessels.
Which can control a rise in blood sugar levels, drinking a cup of coffee before a meal or after a meal?
Drinking a cup of coffee before a meal controls a rise in blood sugar levels.
Sugar and fat contained in a meal are absorbed in the blood vessel from the stomach and the intestine, but too much amount of sugar and fat raises blood sugar level rapidly and damages the blood vessel. Caffeine has the function to prevent the absorption of sugar and fat in the stomach and the intestine, so drinking a cup of coffee before a meal can be expected to prevent a rapid rise in blood sugar level.
Waste products like body cells are accumulated in the body with age. Then the immune cell which is supposed to protect our body attacks the cells that became waste products considered as the enemy, causing small inflammation.
This small inflammation is the cause of aging.
The small inflammation continues to increase all over the body with age.
It has turned out that there is a substance that slows aging. Administration of the substance prevents the cells that became waste from being attacked by the immune cells and inflammation is far less likely to happen.
The mice in Fig. 1 are the same age (80 years old if human). The left mouse, which looks young, was administered the substance and the right mouse, which looks old, was not administered the substance.
The substance that slows down aging is polyamine.
Polyamine exists in all the creatures and we can’t live without it. The amount of polyamine decreases with age, while the amount of inflammation increases with age in inverse proportion to the amount of polyamine.
Polyamine was known as the substance that increased the cell and was necessary when we grew up. It has recently turned out that polyamine slows down aging.
The food that is rich in polyamine is soy products and mushrooms.
It requires a few months to more than a year to show the effect by eating soy products and mushrooms, so it is important to eat them every day.
The young heart has a lot of capillaries and the blood circulation is good so that sufficient nutrition is delivered and the heart can beat vigorously.
But the number of capillaries decreases with age so that the nutrition delivered to the heart also decreases, making the heart beat weak. Ignoring this condition can cause serious heart diseases.
But recently a substance to stop the aging of heart has turned out.
The substance is GLP-1.
According to a research published on The New England Journal of Medicine, people who took GLP-1 for 3 and a half years had 22% less development of heart diseases that people who didn’t. Therefore, GLP-1 can be expected to prevent the aging of the heart and keep vigorous heartbeat.
GLP-1 is a hormone secreted from the small intestine.
The keys to increase the secretion of GLP-1 are:
(1)What to eat
(2)When to eat
(1) What to eat
The important things of what you eat are foods containing proper amount of sugar and insoluble dietary fiber, which stimulates the small intestine and promotes the secretion of GLP-1.
The foods containing proper amount to sugar and insoluble dietary fiber are root vegetables such as carrot, burdock, potato, sweet potato, yam, etc. Different from carbohydrate, the sugar contained in root vegetables is appropriate to stimulate the small intestine and root vegetables are rich in insoluble dietary fiber as well (Fig. 1).
(2) When to eat
The important thing of when to eat is eating 3 meals a day at the same time. This makes the small intestine stimulated at the same time, leading to more secretion of GLP-1.
GLP-1 originally got attention as a hormone lowering blood sugar and is used as the medication for diabetes. But it has turned out that GLP-1 protects the blood vessels of the heart as well.
2 functions of GLP-1
(1) It was said that lost capillaries wouldn’t increase again, but according to various researches, GLP-1 can increase capillaries.
(2) It was also said that plaque, which rapture causes heart attack, created once in the blood vessel wouldn’t be removed, but GLP-1 can decrease plaque, prevent the hardening of the arteries and protect the function of the heart.
Eating root vegetables at the same time 3 times a day stimulates the small intestine regularly and activates the secretion of GLP-1. It seems a little difficult.
But there is a food that is easy to take with you and is expected to secrete GLP-1.
Almond is the food expected to secrete GLP-1.
Nuts are rich in insoluble dietary fiber and almond has a higher content of insoluble dietary fiber than other nuts and root vegetables.
So it is recommended to eat root vegetables 3 times a day at the same time as often as possible and to take almonds when you can’t eat root vegetables at the regular time.
In UK, it is very common method to control the symptoms of pollen allergies.
The method is applying Vaseline in the nostril.
Pollens break when they come into the nostril and more allergen substances come out like the time of pollination. Nasal discharge is mildly alkaline which is suited to break pollens.
Vaseline prevents pollens from breaking because Vaseline is not water but mineral oil.
Applying Vaseline in the nostril prevents the symptoms in the eyes because there is nerve reaction between the eye and the nose.
How to apply Vaseline
Apply Vaseline around the entrance of the nostril with cotton swabs.
Sometimes blow your nose and apply again 3 to 4 times a day.
But if you have seborrheic dermatitis which the skin is sensitive to oil, avoid using Vaseline.
(1) Vaseline prevents pollens from going into the nostril, preventing the allergens of the husk.
(2) Vaseline prevents crushing husk of pollens, preventing the allergens of the inside.
Other preventative measures
(1) Sun bathing: Vitamin D produced by sun bathing suppresses allergy reactions (15 minutes a day, 2 times a week).
(2) Clean the floor: Pollens are difficult to be accumulated on the slippery floor.
(3) Mask: recent masks can cut pollens by 99 %.
