Sexual health education(things to know about your sexual health before it's too late) Sexual health is an important part of our physical and mental health. When we talk about someone’s sexual health, we are not only referring to the presence of a disease or dysfunction, but also how they feel physically, emotionally, socially, and spiritually about their own sexuality. Good sexual health requires a positive and respectful approach to sexuality and sexual relationships. Sexual experiences should be safe and pleasurable, free of coercion, discrimination, and violence. Good sexual health is about making choices around sex and sexuality that are right for your own body and mind. Improving your own sexual health There is still a lot of stigma around sex and many publications tend to focus on the “risks” involved with sex (for example with regards to sexually transmitted infections (STIs) or unintended pregnancies) rather than emphasizing the fact that it is an important and natural part of life and human behavior. Good sexual health involves: Respecting and recognizing your own and others sexual rights Having access to accurate sexual health information, education, and care Taking steps to prevent unintended pregnancies and STIs or seeking immediate care and treatment if needed Experiencing sexual pleasure, satisfaction, and intimacy when or if desired Communicating honestly with sexual partners or healthcare providers about your own sexual health. Are you ready for sex? Only you can determine, in any relationship, if you are ready to have sex. Pay attention to your feelings; sex can bring about new reactions, emotions and possible risks every time you have sex with a new person. Communicate your thoughts, expectations, and boundaries about sex with your partner before you are in a sexual situation, and don’t be afraid to say “no”. Choosing to take part in one kind of sexual activity doesn’t automatically mean that you’re up for anything. If you don’t feel right about something, say so! Ask yourself these questions: How will I feel about myself after I have sex? Do I think having sex with this person, right now, is a good idea? Am I able to talk with this person about protecting myself against pregnancy or STIs? If any of your answers are “Not good”, or “No”, then maybe sex currently isn’t a good idea for you. Also, if you are new to sexual activity, talk to someone you can trust about how to find and use have you spoken with someone you trust about the different methods of contraception that are available and how to find and use them correctly. Risk factors for sexual health problems People are at higher risk for sexual health issues if they: Take certain medications such as blood pressure medications, antidepressants (e ... https://www.youtube.com/watch?v=1NQHvnjCD9g

New variants of COVID-19 Coronavirus disease (COVID-19) is an infectious disease caused by a newly discovered coronavirus. Most people who fall sick with COVID-19 will experience mild to moderate symptoms and recover without special treatment. HOW IT SPREADS The virus that causes COVID-19 is mainly transmitted through droplets generated when an infected person coughs, sneezes, or exhales. These droplets are too heavy to hang in the air, and quickly fall on floors or surfaces. You can be infected by breathing in the virus if you are within close proximity of someone who has COVID-19, or by touching a contaminated surface and then your eyes, nose or mouth. Symptoms of Covid-19 COVID-19 affects different people in different ways. Most infected people will develop mild to moderate illness and recover without hospitalization. Most common symptoms: fever dry cough tiredness Less common symptoms: aches and pains sore throat diarrhoea conjunctivitis headache loss of taste or smell a rash on skin, or discolouration of fingers or toes Serious symptoms: difficulty breathing or shortness of breath chest pain or pressure loss of speech or movement Seek immediate medical attention if you have serious symptoms. Always call before visiting your doctor or health facility. People with mild symptoms who are otherwise healthy should manage their symptoms at home. On average it takes 5–6 days from when someone is infected with the virus for symptoms to show, however it can take up to 14 days. New Varieties of COVID-19.What is all about? Living things change through mutations in their DNA. When a mutation occurs,a new variant usually appear. It's important to note that viruses make copies of themselves to reproduce. There are lots of copies and some have small changes — mutations — that make changes in the virus as it spreads. Mutations can cause all kinds of changes, including changes that help the virus. The ones that are beneficial for the virus tend to survive and to spread more. One kind of mutation we often see in viruses is a change to a faster spreading version of the virus that is often also less deadly. Currently, there are at least four new variants of COVID-19. The new COVID-19 British scientists discovered a new kind of COVID-19 virus, called B.1.1.7 in September 2020. In December 2020, they increased restrictions and shutdowns, but the new strain of the virus was already responsible for about two thirds of the new cases of the coronavirus by that time. Another new kind of COVID-19 turned up in South Africa. Like the British variant, it is more contagious but not more deadly. A third variant showed up on Nigeria. There are also now two new strains that seem to have developed in the United States. Researchers in Ohio identified these new ... https://www.youtube.com/watch?v=rqY5jqQwSQE

The human body(Organs of the body) Organ system — a group of organs that contribute to specific functions within the body. The human body consists of eleven organ systems, each of which contains several specific organs. An organ is a unique anatomic structure consisting of groups of tissues that work in concert to perform specific functions. Organ System Functions Organs Integumentary Functions Barrier to invading organisms and chemicals Temperature control Organs Skin Hair Subcutaneous tissue Skeletal Functions Supports and moves body Protects internal organs Mineral storage Blood formation Organs Bones Cartilage Ligaments Bone marrow Muscular Functions Locomotion Heat production Organs Muscles Tendons Nervous Functions Coordinates activities of other organ systems Responds to sensations Organs Brain Spinal cord Nerves Eyes Ears Endocrine Functions Regulates body functions by chemicals (hormones) Organs Pituitary gland Parathyroid gland Thyroid gland Adrenal gland Thymus Pancreas Gonads Cardiovascular Functions Transports oxygen and nutrients to tissues Removes waste products Organs Heart Blood Blood vessels Lymphatic Functions Returns tissue fluid to blood Defends against foreign organisms Organs Spleen Lymph nodes Thymus Lymphatic vessels Respiratory Functions Oxygen/carbon dioxide exchange Organs Lungs Trachea Larynx Nasal cavities Pharynx Digestive Functions Processes foods Absorption of nutrients into body Organs Stomach Intestinal tract Liver Pancreas Esophagus Salivary glands Urinary Functions Elimination of wastes Regulates pH and volume of blood Organs Kidneys Urinary bladder Urethra Reproductive Functions Produces germ cells (eggs and sperm) Environment for growth of fetus (female) Organs Ovaries Uterus Mammary glands Testes Prostate gland External genitalia Subscribe to my channel:https://youtube.com/channel/UCbhl17sTpk4jSWc9Wo-kR7A Follow our Facebook page:www.facebook.com/streetdoctorcommunity ... https://www.youtube.com/watch?v=DK3-0cs6hF4

What is cancer and types of cancer Cancer is not a single disease. It's a group of diseases characterized by their ability to cause cells to change abnormally and grow out of control. Most types of cancer form a tumor, a lump or mass of cancerous cells. Cells from a tumor may break away and travel to other parts of the body, where they can settle and multiply. This spreading process is called metastasis. New cancers that have broken off and spread from the original tumor are called metastases. Not all tumors are cancerous or malignant; some are benign (non-malignant), don't spread, and aren't life-threatening. And a few cancers don't form masses or lumps, such as those that affect the blood, such as leukemia. Symptoms Symptoms vary widely depending on the type, location, size, and extent of the cancer. Some cancers can exist for many years without causing any symptoms or decrease life expectancy. Common examples are small, non-aggressive prostate and breast cancers. Other cancers can be relatively small and localized to one spot but cause significant pain. Widespread cancer can often lead to marked fatigue, weakness, loss of appetite, and weight loss. Some cancers release substances into the blood that can cause symptoms unrelated to the location or size of the original tumor. For example, one type of lung cancer produces chemicals that trigger unusual neurological symptoms. Diagnosis Your doctor will review your medical history and perform a thorough physical examination. He or she will ask about your family history of cancer. In the initial phase of diagnostic evaluation, blood tests and CT scans of the chest, abdomen, and pelvis are performed. Depending on the results, follow-up tests may include MRI and PET scans. Almost always, a biopsy is necessary to confirm the diagnosis and to provide information that will guide prognosis and therapy. Expected Duration How long cancer lasts depends on its type and response to treatment. Some cancers grow so slowly that they persist, but never cause harm. Other cancers can grow and spread quickly despite therapy. Prevention The number one way to prevent the most dangerous types of cancer is to not smoke cigarettes or use other tobacco products. Other ways to help prevent cancer include: getting certain vaccines to prevent cancer related viral infections, such as the human papilloma virus (HPV) vaccine to prevent cancer of the cervix and other cancers, and the hepatitis B vaccine to prevent cancer of the liver getting screened for colon cancer starting at age 50, or younger if you have personal risk factors practicing safe sex to avoid HIV infection using alcohol in moderation, if you do drink eating a diet rich in fruits and vegetables staying physically active and exercising regularly.
