Hypertension, also known as high blood pressure, is a chronic medical condition in which the blood pressure in the arteries is persistently elevated. It is a major risk factor for cardiovascular disease, including heart attack and stroke.

Signs and Symptoms

Hypertension is often called the "silent killer" because it typically has no symptoms until it has caused significant damage to the heart and arteries. Some people with high blood pressure may experience headaches, dizziness, or shortness of breath.

Causes

The exact cause of hypertension is often unknown, but several factors can contribute to its development, including:

• Genetics
• Unhealthy diet, particularly high salt intake
• Lack of physical activity
• Obesity
• Excessive alcohol consumption
• Smoking

Diagnosis

Hypertension is diagnosed by measuring blood pressure using a sphygmomanometer. A reading of 140/90 mmHg or higher is generally considered high.

Treatment

Treatment for hypertension typically involves lifestyle changes and medication. Lifestyle changes may include:

• Eating a healthy diet
• Reducing salt intake
• Engaging in regular physical activity
• Maintaining a healthy weight
• Limiting alcohol consumption
• Quitting smoking

Medications used to treat hypertension include diuretics, beta-blockers, ACE inhibitors, and calcium channel blockers.

Complications

If left untreated, hypertension can lead to serious health problems, including:

• Heart disease
• Stroke
• Kidney failure
• Vision loss

Prevention

Preventing hypertension involves adopting a healthy lifestyle, such as eating a balanced diet, exercising regularly, and avoiding tobacco and excessive alcohol use.

A Dheki is a traditional rice husking device used in the Indian subcontinent, particularly in rural areas of Bangladesh, India, and Nepal. It is a manual foot-operated wooden machine that plays a crucial role in the post-harvest processing of paddy into rice, making it an integral part of the agricultural heritage of these regions.

Description

The Dheki consists of a large, heavy wooden beam mounted on a fulcrum, with one end designed to hold a pestle that pounds the paddy, and the other end serving as the foot-operated lever. The device is typically operated by women, who use their body weight to press down on the lever, causing the pestle to lift and then forcefully strike the paddy contained in a stone or wooden mortar. This process separates the rice grains from their husks.

Operation

Operating a Dheki requires skill and coordination, as the operator must maintain a rhythmic motion to efficiently husk the paddy. The process is labor-intensive but is considered to produce higher quality rice compared to mechanical mills, as it is less likely to break the grains and often retains more of the nutritional value.

Cultural Significance

The Dheki is not only a tool for rice processing but also a symbol of rural life and traditional farming practices in the Indian subcontinent. It has been featured in folk songs, stories, and paintings, reflecting its importance in the agricultural and cultural landscape. Despite the advent of modern milling technology, the Dheki remains in use in many areas, cherished for its simplicity, sustainability, and the quality of rice it produces.

Challenges and Preservation

The use of the Dheki is declining due to the labor-intensive nature of its operation and the increasing availability of electric and diesel-powered rice mills. There are concerns about the preservation of this traditional technology and the knowledge associated with it. Efforts are being made by cultural preservationists and some rural communities to keep the tradition alive, recognizing the Dheki's role in promoting sustainable agriculture and preserving cultural heritage.
