My Blood Pressure is 150/100 is it Serious?

A blood pressure reading of 150/100 mmHg indicates that your blood pressure is elevated. Blood pressure is typically measured in millimeters of mercury (mmHg), with the first number representing systolic pressure (pressure in the arteries when the heart beats) and the second number representing diastolic pressure (pressure in the arteries when the heart is at rest between beats).

In general, a blood pressure reading of 150/100 mmHg falls within the stage 2 hypertension category according to the guidelines set by the American Heart Association (AHA). 

Here's a breakdown of the categories:

• Normal: Systolic <120 mmHg and diastolic <80 mmHg
• Elevated: Systolic 120-129 mmHg and diastolic <80 mmHg
• Stage 1 hypertension: Systolic 130-139 mmHg or diastolic 80-89 mmHg
• Stage 2 hypertension: Systolic ≥140 mmHg or diastolic ≥90 mmHg

With a reading of 150/100 mmHg, you fall into the stage 2 hypertension range. Hypertension, especially when uncontrolled, can lead to serious health complications such as heart disease, stroke, kidney damage, and other vascular issues.

It's important to note that a single high reading doesn't necessarily mean you have hypertension. Blood pressure can fluctuate throughout the day due to various factors such as stress, physical activity, and diet. However, consistently high readings should be taken seriously and addressed with your healthcare provider.

To manage high blood pressure, lifestyle changes such as adopting a healthy diet (low in sodium and high in fruits, vegetables, and whole grains), regular exercise, maintaining a healthy weight, limiting alcohol intake, and quitting smoking can be beneficial. In some cases, medication may also be prescribed by a healthcare professional to help lower blood pressure.

It's crucial to consult with your healthcare provider for a comprehensive evaluation and personalized management plan based on your individual health status, medical history, and any underlying conditions you may have. Regular monitoring and management of blood pressure are essential for maintaining overall health and reducing the risk of associated complications.

Why aren’t ultra high voltage transmission lines insulated?

They are insulated, by 10 or 20 feet of air, and by glass insulators at every support point.

They don’t use conventional PVC or thermoplastic insulation like low voltage wiring because

• up in the air they are protected from accidental contact
• thermoplastics will break down from UV exposure and have to be replaced periodically - a high maintenance cost. Air is free, no-maintenance, and lasts for ever
• ultra HV will require hugely thick and costly insulation to insulate it.
• insulation adds cost not only for the insulation but also because the wires become heavier and need to be stronger to support the weight, and the towers then need to be closer together, etc.
• cladding Insulation degrades the thermal performance. Bare wire has the highest heat dissipation, clad wire is usually thermally insulated and the I-R drop heats the wire increasing resistance and lowering power carrying capacity; bare wire has the highest thermal performance.
