The cardiovascular (heart and circulatory system) and pulmonary (lung) effects of sleep apnea are very serious; over a period of years these effects become life-threatening. Strokes are three times more common in heavy snorers than in nonsnorers, and heart attack is more than 20 times more likely in people with untreated sleep apnea. The cardiovascular effects of sleep apnea result in the nocturnal sudden death of approximately 2,000 to 3,000 people per year in the United States.

Low blood oxygen concentration during the night is typical in a thực phẩm người cao huyết áp person with sleep apnea. This is responsible for much of the long-term harm resulting from sleep apnea. With each apnea event, the blood oxygen drops to an abnormally low level, depriving the body's cells of oxygen. The brain is particularly susceptible to low oxygen. If the low blood oxygen is severe and continues over a long period, it can unfavorably affect the brain. This may explain the changes in personality, memory, alertness, and coordination seen in people with sleep apnea. Let's look at some of the ways in which sleep apnea can damage people's health.

High blood pressure is one important cardiovascular effect of low blood oxygen. High blood pressure is seen in 35 percent to 50 percent of sleep apnea patients. Chronic high blood pressure results in enlargement of the heart, which is a risk factor for stroke and heart failure.

The relationship between high blood pressure and sleep apnea is complicated and not well understood. Some people have significant improvement in their blood pressure once their sleep apnea is treated. Other people show little change because their high blood pressure has other causes.

Blood pressure may be indirectly improved when the treatment of sleep apnea allows the patient to lose weight and enjoy regular exercise. Excess weight contributes to high blood pressure, and regular exercise can help to lower blood pressure.

Patients on high doses of blood pressure medications should make sure their doctors follow them carefully after their sleep apnea is treated to see if they need less medication. Otherwise they may develop sympstoms of low blood pressure because their body no longer needs so much medication. Careful adjustments of medications are necessary.

Sleep apnea contributes notably to a particular type of high blood pressure: unusually high pressure in the artery that carries blood from the right side of the heart to the lungs. This occurs mainly in people who have other health problems and already have low blood oxygen when they are awake. In time this condition can lead to enlargement of the right side of the heart and fluid congestion in the lungs.

Arrhythmia (abnormal heart rhythm) is seen in more than 90 percent of sleep apnea patients. Abnormal slowing of the heart, long pauses (more than two seconds), extra beats, and several other types of arrhythmias are associated with sleep apnea. People with sleep apnea are thought to run a higher than normal risk of sudden death from heart failure during the night, probably because of a fatal arrhythmia.

The operation of the lungs is affected by changes in blood pressure (described earlier) that result from low blood oxygen. In addition, the low oxygen and high carbon dioxide concentrations in the blood result in abnormal blood chemistry. These changes in blood chemistry also disturb the functioning of the lungs.

The combined damage from cardiopulmonary disturbances —abnormal blood pressure relationships in the heart and lungs, abnormal blood chemistry from too much carbon dioxide and too little oxygen, arrhythmias — is thought by most sleep specialists to be the greatest long-term danger to health from sleep apnea.

Erectile problems can occur in the male of any age. A number of factors contribute to ED including both physical and psychological causes; physical causes include high blood pressure, high cholesterol, heart disorder, overweight, sleep problems, substance abuse, and alcoholism; while psychological causes such as anxiety, depression, relationship issues, stress or poor communication with the partner.

Erectile issues occur normally as a result of not having a good blood supply to the male organ, thus foods that are good for your vascular system also help in preventing ED. Some of the foods include:

Leafy green vegetables, such as celery and spinach, are thought to increase the blood circulation owing to their high concentration of nitrates. Beet juice has been known to be actually high in nitrates. Nitrates are vasodilators, meaning they open up blood vessels as well as augment the blood flow. A lot of years before the U.S. Food and Drug Administration have recommended the first ED drug in 1998, a number of case reports on the favorable effects of nitrates for ED had already been available. The ED medications used today are based upon the relaxing effects of nitrates on the blood vessels that supply the male organ.

Lycopene is one of those phytonutrients that is known to be just mind-blowing for circulation and is thought to be good for sexual problems. Lycopene has been thought to be present in the deep red fruits such as tomatoes as well as pink grapefruits. A few research studies have found that lycopene may be absorbed best when combined with oily foods such as avocados as well as olive oil. Thus you might want to make yourself an ED-fighting salad. Studies have also shown that antioxidants including lycopene help to battle against male issues such as male infertility and prostate cancer.

A recent research study has observed that males having the problem of erectile dysfunction that had pistachio nuts on a daily basis for three weeks experienced noteworthy improvement in their sexual troubles, including ED, sexual desire, and complete pleasure. The benefits of pistachios in solving the erection troubles may be as a result of a protein named as arginine, which may aid relaxation of the blood vessels.

Some research studies have shown that watermelon is thought to exert positive effects on erectile dysfunction that are comparable to the ED medicine Viagra and is thought to increase sexual desire. Watermelon is high in valuable constituents known as phytonutrients. Phytonutrients are nothing but these antioxidants. One of their advantages is that they relax the blood vessels that deliver an erection. Even though watermelon is known to contain 92 percent water, the other 8 percent may work wonders for your heart as well as your sexual pleasure.

Research studies have also found that flavonoids in dark chocolate have been known to make better your blood circulation; which could be good for erection issues that occur because of poor circulation. Flavonoids are naturally-occurring antioxidants that help in looking after plants from toxins and help in renewing the cell damage. Studies show that flavonoids, as well as other antioxidants, have similar effects on people. They may help in lowering blood pressure and reducing cholesterol, both of which are factors that add to erectile dysfunction.

Oysters have always had an aphrodisiac status. One reason may be that oysters contain rich levels of the mineral zinc, which plays a key role in the production of the male hormone testosterone, and low levels of testosterone could be one reason for erectile dysfunction.
