A simple explanation would be that Natural sunlight varies during the day from low UVB in the early morning to high UVB in the mid day sun. Low pressure tanning has the sunburn potential of the midday sun and the sun tanning potential of the early morning sun. High pressure offers the tanning potential of the mid-day sun and the burning potential of the early morning sun.

High-Pressure tanning utilizes very small lamps that produce up to 20 times the power of those used in base beds. These extremely powerful lamps emit less than 1% UVB making sunburn highly unlikely. While VHR systems often use these lamps for facials, high-pressure tanning systems feature full body coverage. These luxurious systems will let you achieve an incredibly deep, dark tan in only 3 short sessions.

A high-pressure bed is composed of high wattage lamps which produce UV A rays. A regular- pressure bed is composed of lower wattage bulbs which produce UV B rays. UVA and UVB are both forms of ultraviolet light emitted by the sun. While both are involved in obtaining a tan, they each penetrate your skin to cause different reactions. While UVB is a necessary ingredient for acquiring a tan it stimulates melanocytes in your skin to produce melanin while UVA darkens the melanin, forming a tan.

High pressure beds allow for a deeper, darker tan. Thereby, increasing the longevity of your tan. The high pressure bed will also build up your base tan faster. Once your base tan is developed, continual tanning in a high pressure bed would require less frequent trips to the salon. Which is a great time saver for that busy on-the-go tanner.

Your heart pumps blood through a network of arteries, veins, and capillaries. The moving blood pushes against the arterial walls, and this force is measured as blood pressure. High blood pressure results from the tightening of very small arteries (arterioles) that regulate the blood flow through your body. As these arterioles tighten (or constrict), your heart has to work harder to pump blood through the smaller space, and the pressure inside the vessels grows.

Low pressure is 1 – 10 psi and does not need an external air supply source. Airsleds use a self-regulating blower that automatically adjusts to increases in weight. The system is contained and portable. High pressure is over 10 psi, needs an external air supply source and an air regulator.

Low pressure units emit both UVA & UVB at a lower energy level. Low pressure units are the traditional beds you normally think of when you think of tanning beds. To build your base tan in low pressure units, you'll usually start off with about ? of the recommended maximum tanning time and increase by a minute or two with subsequent visits*. High pressure units give you immediate results. By filtering out the UVB rays (burning rays), you can tan quickly without burning.

If you don't fancy being trapped in a small, claustrophobic bed, high pressure tanning beds allow you to get the great tan you want without the headaches. High pressure beds are engineered with open sides so that most of the space around you is... Your skin is a very clever organ. No matter which in the arsenal of developments in anti aging skin care products are proudly emblazoned on the bottle and in the marketing literature, your skin knows the truth. And whilst it may play the game for a...

Low pressure units emit both UVA & UVB at a low energy level. Low pressure units will give more of a red tone tan, and you'll need to maintain more often. High pressure units generate UVC, UVB, & UVA, but by means of a sophisticated filtering system, only UVA is emitted during a tanning session. It will take fewer sessions with a high pressure unit it to build a golden tan and to keep it.

Blood pressure is a measure of how hard the blood pushes against the walls of your arteries as it moves through your body. It's normal for blood pressure to go up and down throughout the day, but if it stays up, you have high blood pressure. Another name for high blood pressure is hypertension. When blood pressure is high, it starts to damage the blood vessels, heart, and kidneys. This can lead to heart attack, stroke, and other problems.

There are at two explanations for the positive effects of slow breathing on blood pressure. The first is a simple physiological response: Breathing slowly and deeply relaxes muscle tension, particularly in the chest area, which allows the blood vessels to open up and relieve pressure on the heart. Now there is a new theory proposed by Dr. David Anderson of the National Institute of Health that has less to do with relaxation.

In most cases, doctors can't point to the exact cause. But several things are known to raise blood pressure, including being very overweight, drinking too much alcohol, having a family history of high blood pressure, eating too much salt, and getting older. Your blood pressure may also rise if you are not very active, you don't eat enough potassium and calcium, or you have a condition called insulin resistance.

Most people find out they have high blood pressure during a routine doctor visit. For your doctor to confirm that you have high blood pressure, your blood pressure must be at least 140/90 on three or more separate occasions. It is usually measured 1 to 2 weeks apart. You may have to check your blood pressure at home if there is reason to think the readings in the doctor's office aren't accurate.

Get 3,500 mg of potassium in your diet every day. Fresh, unprocessed whole foods have the most potassium. These foods include meat, fish, nonfat and low-fat dairy products, and many fruits and vegetables. Follow the DASH eating plan (Dietary Approaches to Stop Hypertension). This diet is rich in fruits, vegetables, and low-fat dairy products and is low in fat. This information does not replace the advice of a doctor.

High blood pressure, also called hypertension (or "HTN") is the most common of all cardiovascular diseases in the industrialized world. According to research, 44-51% of overweight individuals have high blood pressure.

The American Heart Association considers a normal blood pressure to be less than 119 (systolic) / 79 (diastolic); your doctor or nurse might communicate this as "119 over 79".

High blood pressure is the leading cause of stroke and a major cause of heart attack. It is also strongly associated with type 2 diabetes, high triglycerides, high cholesterol, and insulin resistance. Consistently high blood pressure forces the heart to work beyond its capacity. This can injure blood vessels as well as damage the brain, eyes, and kidneys.

Patients with these medical conditions can safely undergo joint replacement operation. These conditions need to be controlled well with medication prior to surgery.
