Metabolic Syndromes such as hypertension and diabetics are top killer diseases in our world today; everyone appears to be at risk of doing or having something that may lead to any of them. Having any of these medical conditions could further lead to Cardiovascular and Cerebrovascular diseases and some others.
There have been hundreds of researches directed towards knowing more about these conditions, for causes, management and cure; until solutions are found, scientists have to keep researching to get the latest from causes to cure.
In this paper some other possible methods to research into are presented, this has to do with restoring blood pressure to normal or near normal for people that have essential HyPertensioN (HPN), this is ranging from nutrition, to ambient temperature and oxygen-rich air inhalation to help the autonomous nervous system and blood vessels return steady high blood pressure to normal.
It is the brain that controls blood pressure, since little is understood about processes involving certain causes of essential high blood pressure and correction from the brain is developing. This paper is looking at the elasticity of the blood vessels, directing this procedure at the blood vessels where signals about blood pressure are sent to the brain.
HPN patients from this should have steady combinational treatment overtime with believe for relieve. Each procedure is followed after another at intervals which will produce expected results.
For example glycoprotein, antithrombin, collagen, elastin, and other essential make up of blood vessels are administered to patients through natural fruits that contain these sugars and proteins, after which the patient is sited under an ambient temperature that is relatively lower than the one the body is used to, the patient is administered oxygen-rich air to reduce total air pressure in blood also. The procedure is elaborated under the heading below.
Conditional Combinational Treatment
Nutrition. Ambient Temperature. Oxygen
Is focused on food composition that can enhance ‘back to normal’ elasticity for aorta, arteries and arterioles in HPN patients; so that as the pressure of blood hits the walls of the arteries, the arteries due to ‘corrected’ elasticity are able to relax especially during sleep and other times to bring the blood pressure near to normal.
The nutrition can be taken by any mode of ingestion, that will aid the resistance of tunica intima against oncoming pressure, tunica media and tunica adventitia will also be leveraged in the process. There are epithelial cells that make up the tunica intima and other collagen fiber that make up the tunica adventitia and tunica media; these cells are made of glucose, proteins and amino acids. There are fruits that contain these, it is hoped that when absorbed in the body, overtime changes will be seen.
Challenges appear in this approach: the first is that since there is no major damage in any part of any artery so how does the fruit repair the blood vessels? The second one is that there are similar cells available in other parts of the body, if these supplements will not build up the cells of other tissues.
This is where other procedures aside eating those fruits come in; the blood vessels notice slight changes in pressure due to the procedures and possibly let the nutrients of the absorbed fruits make changes through it first before supply to other parts of the body. This presents a direction or blueprint towards achieving the objective, common edible fruits will leverage the epithelial cells, elastin and collagen of the arteries first before the food gets distributed to other parts of the body.
The cell membranes of some of the constituent cells of the blood vessels are renewed by some vitamins, minerals and other class of foods. Some of these other class of food mentioned here are made within the body while ingestion of nourishing fruits further meet renewal needs of the vessels.
If combinational therapy is administered to those who have HPN making selected fruits & other conditions directionally work to enhance the elasticity of the arterial wall and the capacitance of the blood vessels.
These may also provide some help for the arterial baroreceptors such that ensuing changes observed in enhanced capacitance are sent as messages to the brain making reluctant baroreceptors that becomes less sensitive to changes in people with HPN to avoid maintaining the high blood pressure as normal and respond to changes obtained from the week long treatment.
For fruits like water melon, garlic, lemon etc they can provide the body with glycoprotein, amino acids and monosaccharide; they will be eaten to meet the conditions to have desired changes against the state of HPN in man.
This will help increase the elasticity of the arterial wall to foster distending and recoil so as to promote blood flow in small arteries and arterioles and overall elastic matrix.
Taking a given amount of watermelon for a period of time helps to increase the diameter of the artery according to a research report. Watermelon contains an amino acid called arginine. This helps to produce a compound which is a useful constituent of the arterial wall. 
Garlic and Lemon
Garlic produces Hydrogen sulfide when it interacts with the blood cells; this compound makes sooth muscle cells to relax and takes aim at membrane channels. Garlic molecules called polysulfide possess the capacity to increase hydrogen sulfide production; Hydrogen sulfide lowering blood pressure may however be linked to oxidative process in cells.  Lemon is said to strengthen the arterial wall due to its vitamin C constituents. 
This high in antioxidant fruit helps reduce blood pressure in a way also. 
This has been proved from certain studies, and will also be good to be used in this treatment.
These fruits and some others presented in the Web references should be taken in batches according to order to be provided on the Treatment heading, since they have the potential to lower blood pressure, additional therapy provided will ensure essential blood pressure is reduced or returned to normal.
Following ingestion of the fruits, the patient is expected to stay under temperatures less than usual with respect to individuals, 2-5degree Celsius lower. The patient is expected to remain under that condition after these fruits are taken. It is known that hot food is cooled in the stomach and cold food is warmed in the stomach, so the temperature of the fruit is not the concern here, rather it is said that under cold external conditions, peripheral blood vessels constrict and visceral vessels get congested changing secretion and absorption pattern. 
The patient should stay there for some time to ensure that the body absorbs digested fruits and they act as expected in the blood vessels.
Lower temperatures will be helpful for blood pressure reduction with reference to vasoconstriction and vasodilation. The body should better respond to healing at the time.
Humans inhale and exhale air which contains some other gases at atmospheric pressure; a simple logic towards this is using oxygen therapy for essential HPN patients with the hope of ensuring that the fraction of oxygen gas in the blood is raised to about 30-40% against the usual 21% inhaled in air. The major need for air in man is oxygen; this paper seeks to have more amount of the required gas (oxygen) in the usual proportion of air delivered to pass through the blood vessels.
The blood vessel of man (healthy or with HPN) is used to certain pressure of normal air combined with blood. Inhalation of oxygen-rich air under same conditions as normal air will have the total pressure which the air and blood exerts to be changed being reduced by a certain amount. This will help reduce the contribution of air & blood pressure against the walls of the blood vessel.
This treatment is combinational and oxygen-rich air breathe will be used. This heading presents some calculations, (mass-volume ratio and partial pressures) showing how oxygen-rich air will help reduce contribution of air to blood pressure during this treatment in man.
The inclusion of oxygen for this treatment is to breathe it under normal atmospheric pressure as air. This therapy under careful conditions (due to risk of flammability) will have patients take oxygen that billows out of a vent with their nostrils close to the vent, to receive first hand oxygen-rich air under normal atmospheric pressure condition.
This will prevent patients using this therapy against possible complications that may arise with oxygen therapy and will ensure the oxygen-rich air is effective for the treatment. The method of inhalation will definitely be reviewed due to cost, recycling and flammability. Calculations are presented below:
If we have a certain volume of air, A, containing all the gases by volume; and we have another one, B, containing more volume of oxygen lets say 40%, having reduced volume of nitrogen, B, will comparatively exert lesser pressure than A, making pressure applied by a oxygen-enhanced air potent.
Air contains 78% of Nitrogen, 20.9% of oxygen, 1% of water vapor, 0.97% of inert gases and 0.035% of Carbon (IV) oxide. Usually increased mass equals to increased volume, but may not be vice versa for gases where pressure is also involved in mass-volume relationship. The relative atomic mass of Nitrogen is 14, Oxygen is 16.
My simple calculation for mass-volume ratio of Nitrogen and oxygen in normal air is:
14*78% = 10.92
16*21% = 3.36
If the percentage of oxygen is increased to 40%; which is (21 + 19) % and Nitrogen is reduced to 59% which is (78 - 19) %
My simple calculation for mass-volume ratio of Nitrogen and oxygen in oxygen-rich air is:
14*59% = 8.26
16*40% = 6.4
The volume of oxygen is therefore increased in the same amount of air, reducing the partial pressure of nitrogen in inhaled air and therefore reducing the total pressure exerted by inhaled air (and blood) in blood vessels. Nitrogen definitely exerts it own pressure, with this calculation, additional 19% increase in oxygen available in the rich air will be uniform with the usual 21% pressure. This diminutive increase in pressure will be balanced by reduced pressure from the new nitrogen volume in the blood vessels. Making the total volume of air exerted in blood vessels reduced for that time.
There is a certain volume of air that humans breathe in with their nostrils; this refers to the amount of normal air that enters the nostrils during breathe. Normal air contains the 21% of oxygen enough for metabolism in hale persons. Under improved oxygen administration process, oxygen-rich air can be inhaled as normal air without being under pressure (hyperbaric) as used in other therapeutic purpose.
A critical thought here is that the partial pressure of 78% of Nitrogen intake (in normal air) which the blood vessels are used to, will be reduced when 40% oxygen-rich air is inhaled.
For the oxygen-rich air, oxygen is 40% = 0.4, under atmospheric pressure, 0.4*760mmHg = 304mmHg. This is the partial pressure 40% oxygen-rich gas will produce under atmospheric pressure in a container. This is not expected to be same in human body because the oxygen-rich air for this therapy will be inhaled like air leaving additional pressure out.
According to studies, Nitrogen in normal inhaled air help to keep the alveoli expanded. For 40% oxygen-rich air, it does not reduce the Nitrogen role much since the therapy is for a short time interval.
This treatment is expected to be administered and changes will be monitored.
This therapy will make more sense close to bed time, meaning that patients may pass the night at medical center or go home relaxed after treatment. The reason for this is to ensure that the body is rested after the treatment while healing continues within.
This treatment should run through one hour daily for the seven days in one week.
Patients can take 40g of three of the fruits mentioned under the nutrition heading after which they relax under a low temperature room guarding some parts of their body while others are open to feel the cold.
After about 15minutes in the low temperature room; the patient is moved to a room where oxygen-rich air vent is; the patient should sit close to the vent to inhale the oxygen-rich air for about twenty minutes, and return to the low temperature room for another twenty minutes. Reasons for these have been explained under respective heading above.
So, what do we expect to get? The patient may enter the low temperature room thirty minutes after ingesting all the fruits to let absorption coincide with following procedure. Low “unusual” temperature is set to effect changes on blood flow in blood vessels with respect to vasoconstriction and vasodilation respectively; while the oxygen-rich air will see that absorbed fruit, vasodilation (after vasoconstriction) are all working to bring the blood pressure down.
Truly, only the effect of the fruit may outlive the one hour (or less) treatment period, those other conditions will ensure that while the fruits are absorbed and working as they should, blood pressure is decreased in a little way and may just help the baroreceptors notice the obvious change.
Blood pressure will be monitored in the morning before people go for their usual activity; the blood pressure reduction that stays through the night, should be seen in the latest result of the morning. The body after the first day may however return to its usual high blood pressure.
Different fruits will be administered on different days with different sequence; dwelling in low temperature room and oxygen-rich inhalation will also follow different pattern on other days as to which comes first and comes after. It may also be administered somehow together also. The oxygen-rich air should only be inhaled in twenty minutes or less per therapy.
This treatment should reduce blood pressure to 5mmHg lesser than usual high and as the treatment stays over a week, should increase to 10mmHg or more depending on the lifestyle changes the patient applies within that week.
This treatment will work and should go farther by reducing way-to-high blood pressure if the method is reviewed and followed. I can imagine that we have the HPN scourge out of man troubling healness list. It will be a leap for science.
