vegetables that keep you healther !!!

Cucumbers  

Cucumbers are your best bet in summers as they are 96 per cent water and eaten in raw green state. They contain vitamin C and silica which are known for tissue growth and skin cleansing properties. Their high water content makes them ideal for summers. It is important to eat cucumbers with the skin because their outer skin is rich in potassium, magnesium and fibre which has tremendous health benefits for the body.  


Brinjal
Brinjal or baingan is a common purple vegetable containing lots of dietary fibre and antioxidants. It is an excellent source of molybdenum, potassium, vitamin K, magnesium, copper, vitamin C, vitamin B6, folate, and niacin. It is known to have a dominant antioxidant which can also lower bad cholesterol. But if you already have kidney problems or gall bladder issues, you should avoid eating brinjal. 

Tomatoes

Listed both in the category of fruits as well as vegetables, the health benefits of tomatoes are splendid in summers. Tomatoes are considered to be helpful in reducing prostate cancer risk and are good for diabetics and heart patients. They are a wonderful source of vitamin C, vitamin A and vitamin K. Other important nutrients in tomatoes include lycopene, potassium, vitamin B6, folate, dietary fibre, manganese, magnesium, niacin, and vitamin E. They are great as coolers.

Green Beans

Green beans are an excellent source of vitamin C and vitamin A, as well as bone-building vitamin K which is important for blood clotting too. They also have antioxidant vitamins that protect cells against oxidative damage and keep the immune system healthy. Vitamin A not only preserves night vision but also keeps skin and the cornea of the eye moist. Green beans are a good source of heart-healthy fibre that helps lower cholesterol levels. They also contain respectable amounts of potassium and magnesium, which help to normalise blood pressure. Green beans make for an excellent dish in the summers as they are light on the stomach. You can even include them in your salad. 

Pumpkin

Pumpkin or kaddu possesses great cooling and diuretic properties. It is also good for digestion and eliminating intestinal worms from the digestive system as it is full of fibre. It contains potassium and also controls blood pressure and sugar as well as stimulate the pancreas. It is excellent in curing skin diseases. Extremely high in fibre and low in calories, pumpkin has disease-fighting nutrients like pantothenic acid, magnesium, and vitamins C and E.

some easy tips to beat the heat !!!!

Despite the severity of the dangers posed by overexposure to summer’s heat, there are easy ways to minimize your risk:

• Wear light colored, loose fitting clothing.
• Wear a wide brimmed hat to shade your face.
• Be sure to stay properly hydrated by drinking more than your usual 64 ounces of water per day. However, do not drink sugary drinks as they will actually increase dehydration.
• Avoid getting sunburned as it negatively affects the body’s ability to cool itself.
• When you are outdoors in the sun take frequent breaks in the shade or in air-conditioned places.
• Avoid exercising outdoors, especially during the hottest part of the day, but if you do decide to venture out make sure to drink 8 ounces of water every 20 minutes, even if you are not thirsty.
• Avoid or at least limit alcohol and caffeine consumption as they are both diuretics and will cause your body to lose even more water.
• Be mindful of the hydration and temperature needs of those around you, especially children, the elderly, and people with chronic medical conditions, who are most at risk for heat related health problems

How Plants Can Change Our Climate?

Plant growth can have a considerable effect on the climate,” says Wolfgang Buermann, a geographer at Boston University. He explains that there are several ways in which plants can alter the temperature of the Earth’s atmosphere. Through the process of photosynthesis, plants use energy from the sun to draw down carbon dioxide from the atmosphere and then use it to create the carbohydrates they need to grow. Since carbon dioxide is one of the most abundant greenhouse gases, the removal of the gas from the atmosphere may temper the warming of our planet as a whole.

Plants also cool the landscape directly through the process known as transpiration. When the surrounding atmosphere heats up, plants will often release excess water into the air from their leaves. By releasing evaporated water, plants cool themselves and the surrounding environment. “It’s like sweating. When you sweat you cool the surface of your skin,” says Buermann. Over a forest canopy or a vast expanse of grassland, large amounts of transpiration can markedly increase water vapor in the atmosphere, causing more precipitation and cloud cover in an area. The additional cloud cover often reinforces the cooling by blocking sunlight.

As plants ‘breathe’ and ‘perspire’ they help cool the atmosphere. Plants consume carbon dioxide—a significant greenhouse gas—in the process of photosynthesis. The reduction of carbon dioxide in the atmosphere has an indirect cooling effect. Plants also cool the atmosphere because they release water vapor when they get hot, a process similar to sweating. The diagram at left shows the microscopic structure of a leaf, and the processes of photosynthesis and transpiration.

CAUSES OF DEFORESTATION

CAUSES OF DEFORESTATION

Deforestation is the permanent destruction of forests in order to make the land available for other uses

CAUSES

There are many causes of deforestation. The WWF reports that half of the trees illegally removed from forests are used as fuel.

Forests are cut down for many reasons, but most of them are related to money or to people’s need to provide for their families. The biggest driver of deforestation is agriculture. Farmers cut forests to provide more room for planting crops or grazing livestock. Often many small farmers will each clear a few acres to feed their families by cutting down trees and burning them in a process known as “slash and burn” agriculture. Not all deforestation is intentional. Some is caused by a combination of human and natural factors like wildfires and subsequent overgrazing, which may prevent the growth of young trees.

SOME OTHER COMMON REASONS ARE:

• To make more land available for housing and urbanization
• To harvest timber to create commercial items such as paper, furniture and homes 
• To create ingredients that are highly prized consumer items, such as the oil from palm trees
• To create room for cattle ranching 

Common methods of deforestation are burning trees and clear cutting. These tactics leave the land completely barren and are controversial practices. 

Clear cutting is when large swaths of land are cut down all at once. A forestry expert quoted by the Natural Resources Defense Council describes clear cutting as "an ecological trauma that has no precedent in nature except for a major volcanic eruption."

DEFORESTATION AND CLIMATE CHANGE

Deforestation is considered to be one of the contributing factors to global climate change.

the No. 1 problem caused by deforestation is the impact on the global carbon cycle. Gas molecules that absorb thermal infrared radiation are called greenhouse gases. If greenhouse gases are in large enough quantity, they can force climate change.

The deforestation of trees not only lessens the amount of carbon stored, it also releases carbon dioxide into the air. This is because when trees die, they release the stored carbon. According to the 2010 Global Forest Resources Assessment, deforestation releases nearly a billion tons of carbon into the atmosphere per year, though the numbers are not as high as the ones recorded in the previous decade. Deforestation is the second largest anthropogenic (human-caused) source of carbon dioxide to the atmosphere, ranging between 6 percent and 17 percent.

How to prevent from heat stress?

The Connecticut Department of Emergency Services and Public Protection offer the following tips during extreme high temperatures:

·         Slow down, and avoid strenuous activity.

·         Wear lightweight, loose-fitting, light-colored clothing. Light colors will reflect heat and sunlight and help maintain normal body temperature. Protect your face with a wide-brimmed hat.

·         Drink plenty of water regularly and often, even if you don’t feel thirsty.

·         Limit intake of alcoholic beverages. They can actually dehydrate your body.

·         Eat well-balanced, light, regular meals.

·         Stay indoors as much as possible.

·         If you do not have air conditioning, stay on your lowest floor, out of the sun. Electric fans do not cool the air, but they do help evaporate sweat, which cools your body.

·         Go to a place where you can get relief from the heat, such as air conditioned schools, libraries, theaters, shopping malls, and other community facilities that may offer refuge during the warmest times of the day.

·         Cover windows that get morning or afternoon sun with drapes, shades, awnings or louvers. Outdoor awnings or louvers can reduce the heat that enters a home by up to 80 percent

·         Avoid too much sunshine. Sunburn slows the skin’s ability to cool itself. If you are outside, use sunscreen with a high SPF (Sun Protection Factor) rating.

·         Never leave children or pets alone in a closed vehicle.

·         Do not leave pets outside for extended periods. Make sure pets have plenty of drinking water.

·         Check on family, friends, and neighbors regularly.

DIFFERENCE BETWEEN HEAT STROLE AND HEAT EXHAUTION AND ITS TREATMENT

Heat exhaustion

Heat exhaustion is a milder entity than heat-stroke that exists on the same continuum of heat-related illness. Heat exhaustion typically is associated with nonspecific signs and symptoms and mild pyrexia Patients may experience nausea and malaise, and show signs of circulatory collapse. Evidence of central nervous system dysfunction should trigger a diagnosis of heatstroke rather than heat exhaustion.

Heat stroke

Heatstroke is a much more severe entity than heat exhaustion. The diagnosis of heatstroke rests on two critical factors: hyperthermia and central nervous system dysfunction. Heat-stroke is a medical emergency, and mortality can approach 10 percent. It is essential that clinicians recognize the signs of heatstroke and initiate cooling rapidly. When appropriate treatment is provided without delay, survival can approach 100 percent. Heatstroke typically range from 40°C to 44°C (104°F to 111.2°F), with reports as high as 47°C (116.6°F), and should be monitored rectally or with a bladder or esophageal probe. However, elevated temperatures are not necessary for a diagnosis of heatstroke. Peripheral temperature measurements may be as much as 1°C lower than core readings, and cooling by emergency medical technicians can falsely decrease peripheral temperatures further.

	Core Temperature	Signs	Symptoms
Heatstroke	> 40°C	Anhydrosis	Fatigue and malaise
		Cardiac arrhythmias	Visual disturbances
		Hyperpyrexia	Weakness
		Coma	Dizziness
