Lesser Known Facts About Blood Donation

Air pollution affects the overall health of a human being. Whether it comes out of exhaust fumes from cars and factories or smoke from burning stubble air pollution, it is a cause of major concern. The effects of this can be seen in the growing number of asthma and other respiratory diseases. These diseases affect adults and children alike, however, it is the younger generation and elderly people who are more susceptible. Hence, it is extremely important to care about the quality of the air you breathe in. 


 ;

What is the significance of the air quality index (aqi)?

The air quality index is a visual representation of pollutant levels in the air around you. A quick glance at this colour coded map can tell you if the air outside your home is likely to harm you or not. The code is broken down into 6 levels ranging from green which signifies minimal impact to red which marks pollution levels that can harm a healthy person and seriously impact those who are already ill. The higher the aqi, the higher the level of air pollution.

 

What are the steps to reduce air pollution?

Simply talking about how there need to be stricter laws about car emissions and the burning of waste will not help you. Here are a few things you can do to protect yourself and your family from the ill-effects of air pollution.


	
	Carpool: exhausts from cars and other vehicles are one of the biggest causes of air pollution. Do your part to reduce air pollution by restricting the amount you use your car. Try taking public transport to work or carpooling with colleagues. Similarly, avoid making individual trips every time you need something from the market. Make a list and when it s long enough, then step out.
	
	
	Limit indoor pollution: do not smoke indoors. When cooking, keep the exhaust fan on so that the smoke produced does not collect indoors. Avoid spraying air fresheners etc. While they may temporarily make the air smell fresh, in the long run, they contribute to air pollution.
	
	
	Use public transport try to use public transport and avoid the use of personal vehicles.
	


How to protect yourself from air pollution


	
	Refrain from morning walks routines to later hours.
	
	
	Use n95/99 face masks whenever you step out.
	
	
	Use air-purifying plants to purify the air around your surroundings.
	
	
	Ventilate your kitchen, and bathroom to keep yourself away from air pollution.
	
	
	Restrict outdoor activities for kids if there is a high level of air pollution
	
	
	Use air-purifiers in your surroundings.
	
	
	Try to take steam with a few drops of eucalyptus oil every day.
	
	
	Keep your car s environment fresh.
	
	
	Ventilate your home, open your windows and doors and allow the air to circulate during mid hours.
	
	
	Eat jaggery (aka gurr) to flush out pollutants from your lungs.
	
	
	Consume a diet rich in vitamin c, omega fatty acids
	


Hence, the other way to cut down this pollution is by bringing significant lifestyle changes in our daily living. Cutting down the number of diesel and petrol vehicles can also prove helpful. People should shift to cng and electric vehicles for daily commuting. These efforts, if practiced on a regular basis, can bring a huge decrease in pollution.

Air purifiers can also be a healthy option for indoor purposes.

Why Should You Care About Air Quality?

World environment day is celebrated annually on 5th june. This day encourages awareness and action for the protection of our environment. It raises the problems facing our environment such as plastic pollution, air pollution, illegal wildlife trade, sea-level increase, sustainable consumption, and food security, among others. 

 ;

World environment day is a reminder for us to pause and reflect on our actions and their subsequent consequences on the planet. 

 ;

When was the world environment first celebrated?

The day was first observed in 1974 in the city of spokane in the usa.

 

History of world environment day (wed)

1972- the un general assembly established world environment day on the 1st day of the stockholm conference on the human environment. ;

1974- the first" world environment day" was held with the theme" only one earth. 

1987- the idea for rotating the center of these activities by selecting different host countries began. ;

 

Why is world environment day celebrated? ;

For a healthy life, the environment plays an important role. It provides us with air, food, etc. The environment is like our neighborhood, its surrounding conditions affect us and also modify development. It is really necessary to address the environmental issues like deforestation, increasing global warming, pollution, wastage and losses of food, etc. Currently, our earth is experiencing a triple planetary emergency: 


	
	Pollution is poisoning our air, land and water. ;
	
	
	Climate is heating up too quickly
	
	
	Habitat loss
	


The deteriorating environmental conditions worldwide had already raised alarms in academic circles, among scholars studying its conditions. However, general masses seemed oblivious to changes that were not directly affecting them.

The world environment day is structured in a manner that allows one country to take up the responsibility of selecting the theme and hosting the key celebrations each year. 

Let's all come together and ensure this unique and beautiful planet remains a comfortable home for humanity.

World Environment Day: What Is World Environment Day And Why It Is Celebrated? 

What are the different types of sickle cell disease?

Sickle cell disease or sickle cell disorder is a term often used to talk about a group of diseases affecting hemoglobin. It is the oxygen-carrying element of blood that makes up 2 alpha globins and 2 beta globins. Sickle cell disease happens due to beta-globin mutation and depending on the abnormality in mutation.

Types-
Sickle cell diseases can be of many types depending on the gene mutation in the blood. Some of the common types are-

Sickle hemoglobin s disease (ss)
Hemoglobin ss disease or sickle cell anemia is the most popular type of scd. It takes place when hemoglobin s gene mutation is inherited from both mother and father. In simple words, it happens when the child inherits one substitution beta-globin gene from each parent. In this type, the body only produces hemoglobin s. It is mostly found in people of african and indian origin.

Sickle hemoglobin- c disease (sc):
Patients with sickle hemoglobin sc disease have a moderately dissimilar swapping in their genes of beta-globin. Here, both hemoglobin c and hemoglobin s are inherited from each parent. It may cause similar symptoms like anemia but remains relatively l. People of west african and mediterranean origin are more prone to this.

Hbs beta-thalassemia
People with this type of scd inherit one sickle cell gene s and one gene for beta-thalassemia from each parent. Zero and plus are the two common types of beta-thalassemia. While beta 0 thalassemia usually takes a severe form, beta + thalassemia is a milder form of the disease.

Sickle beta-zero thalassemia
Beta-zero thalassemia takes form when the child inherits the beta s gene from one parent and beta 0 thalassemia gene mutation from the other. With similar symptoms to anemia, it is a slightly severe form of beta-thalassemia.

Sickle beta-plus thalassemia
Substitutions in both beta-globin genes take place in patients with sickle beta thalassemia (sb) disease. This may even lead to the requirement of blood transfusion if no normal beta globin is produced. Mediterranean and caribbean people are more likely to have this disorder.

Hemoglobin sd, hemoglobin se, and hemoglobin so
These are the few rare and not less common types of sickle cell diseases. They are also less severe. People with these forms of scd inherit one sickle cell gene s and one gene from uncommon hemoglobin (d, e, or o) from each parent.

Sickle cell trait
Hbas
People with sct have one sickle cell gene s and one normal gene a from both mother and father. Ones with this disorder show few to no signs of the disease and usually spend a normal life. However, the risk to their future generations still exists.

	Trouble in speaking
	
	
	Blurred vision
	
	
	A person might have seizures without any previous history of neurological disease
	


 ;

Risk factors of a brain tumor 

There are some risk factors that increase the risk of brain tumors in individuals


	
	The risk of brain tumors increases with age.
	
	
	This condition can also be inherited from the family however, the chances are only 5 to 10 percent.
	
	
	The risk of brain tumors increases in people who have been exposed to ionizing radiation.
	
	
	If a person is exposed to certain chemicals then they have an increased risk of suffering from a brain tumor.
	



 ;

Treatment of brain tumor

 

The treatment of brain tumors depends on the location, size, and type of the tumor. The general health of the patient is also taken into consideration. The treatment which is common for brain tumor is surgery. The objective of the surgery is to remove as much of the tumor as possible without damaging the other parts of the brain. For surgery to take place the tumors must be located within the area of limits of the surgery.

 ;

Doctors may suggest the following treatments according to the type, grade, and position of tumor and the general health of the patient.

 


	
	Surgery
	
	
	Radiation therapy
	
	
	Chemotherapy
	
	
	Anti-seizure medicines
