Puberty is the time when kids grow into young adults through physical and psychological changes. It doesn't happen all at once, but slowly over time. Most females start their puberty between the ages of 8 and 13 . Most of the males start theirs between 9 and 14 . But it can also be possible to start it earlier or later. Hormones from the brain trigger the beggin of puberty. In males those hormones make the testicles to make the hormone testosterone and sperm . In females they make the ovaries to make the hormone strogen and trigger the growth and release of the eggs . Other puberty hormones are from the adrenal glands , and they lead the growth of pubic and underarm hair, body odor and acne . PHYSICAL CHANGES In men : First the testicles get bigger , and hair will sprout out above the penis and on the scrotum. The penis and testes will get larger . Ejaculation and erection will happen. Later, hair will grow under the arm and in the beard area. And that first crack in the...

  Sometimes stress can be a positive force, motivating you. But it is often a negative force. If you experienced stress during a long period of time, it could become chronic —unless you take action. Stress is an automatic response designed by our ancestors to protect us from predators and other threats. Faced with danger, the body stress hormones such as adrenaline and cortisol flood our body. They elevate your heart rate, increase your blood pressure, boost your energy and prepare you to deal with the problem. These days you don't confront the danger of being eaten, but you still have multiple challenges every day. As a result, your body's natural alarm system may be stuck in the on position. And that can have serious consequences for your health. Even short-life, minus stress can have consequences. Major acute stress can have a bigger impact. Repeated acute stress can may also contribute to inflammation in the circulatory system, particularly in the coronary arteries. This is...

A dermatologist is an expert medical doctor and skin surgeons with the skills and experience to offer the best care for the skin. The skin is an organ, which is your first line of defense from a disease. If you were to watch a dermatologist on any day of work, you might see them: - Treat a baby's prominent birth mark that threatens the child's eyesight. - Remove a woman's deadly melanoma at its earliest. - Offer relief for a young person whose chronic eczema makes sleep nearly imposible. - Diagnose the life-threatening liver condition, causing an old man's unbearable itching. - Treat the hair loss of a young girl. Your dermatologist knows the difference between a little problem and a major one. They also understand that a skin condition can have a serious impact in your health and well-being. Sometimes, a skin condition is a sign of a serious underlying health issue. For example, signs of diabetes and heart disease can show up on the skin. For being a dermatologist you ...

  Alzheimer is a type of dementia that affects memory, thinking and behaviour. Symptoms can grow severe enough to interfere with daily tasks. It's the most common cause of dementia, a general term for memory loss and other cognitive abilities serious enough to interfere with daily life.  This disease is not a normal part of aging. It is a progressive disease beginning with mild memory loss and possibly leading to the ability to carry on a conversation and respond to the environment. Researchers believe that genetics may play an important role in developing Alzheimer's disease. However, a healthy lifestyle may help you reduce your risk of developing it. Adequate physical activity, a nutritious diet, a limited alcohol consumption and not smoking may help people. Changes in the brain start years before the first symptom. Alzheimer worsens over time. Memory problems are usually the first warning signs. But the people with it can also experience: trouble handling money, difficulty ...

There are some reasons for different types of pregnancies, including physical differences in a mother's reproductive system, multiple eggs being released, multiple sperm fertilizing the same egg, underlying health conditions of the mother, and other reasons. INTRAUTERINE PREGNANCY A typical pregnancy where the fetus(es) implant inside the uterus, and the placenta attaches to the uterine muscle inside the uterus. ECTOPIC PREGANCY A fertilized egg implants in a location other than the fallopian tube or uterus, such as the neck of the uterus or abdomen. This type of pregnancy is not viable and usually the body aborts the fetus. An ectopic pregnancy can rupture and be life-threatening and may need surgery to fix. - TUBAL PREGNANCY This is a type of ectopic pregnancy. A fertilized egg implants in the fallopian tube instead of the uterus. It's not viable and must be terminated if a miscarriage doesn't occur naturally on its own. INTRA-ABDOMINAL PREGNANCY It tends to occur followi...

More than 12% of the children between ages of 6 and 19 already have hearing damage from loud noises. Your child's hearing health is crucial during their overall well-being and development. Hearing loss is increasingly common among children, teens, and young adults. HOW OUR EARS WORK 1. Outer ear: sound waves enter the outer ear and travel through the ear canal. 2. Middle ear: the sound waves hit the eardrum, causing it to vibrate. These vibrations are transferred to the malleus, incus and stapes. 3. Inner ear: the vibrations hit the cochlea and it creates electrical signals. 4. Brain processing: the auditory nerve carries them to the brain, interpreting them as a sound. MEASURING SOUND Sound is measured in decibels (dB). Sounds at or below 70 dB are generally considered safe. Any sound over 85 dB poses a risk of damaging your hearing over time. A normal conversation is usually between 60 and 70 dB. Music by headphones at maximum can reach to 94 to 110 dB. CAUSES OF CHILDHOOD HEARIN...
