Sleep changes as we age. When we were kids, we needed 10 to 12 hours of sleep, for teens it is eight to 10 and it decreases to seven to nine as we reach adulthood. But there is always a lack of urgency when it comes to sleep and young adults, many of whom prefer staying up and doing different activities. According to the Centre of Disease Control and Prevention, many national surveys show that about 37% of men, and 39% of people from the age of 45 to 64 reported not getting enough sleep.
Many people in America don't sleep the right amount. This means they either sleep too long or not long enough. But what happens to your body when you do not sleep enough? You just feel tired right? No, when you don't get this much sleep, your body can get stressed. This can make you more likely to get sick. A study published by the JAMA Network Open Sleep Trajectories and All-Cause Mortality Among Low-Income Adults showed that people who don't sleep the right amount have a higher chance of dying early. It's like your body needs that time to rest and fix itself. Without enough good sleep, things can start to go wrong. So, getting the right amount of sleep is super important for staying healthy.
Scientists wanted to see how sleep habits affect people's health over many years. They looked at almost 47,000 people who were between 40 and 79 years old. They asked them about their sleep habits when the study started, and then again, a few years later. The scientists wanted to see if people's sleep habits changed. They divided people into groups based on if they started with too much or too little sleep, and if their sleep changed over time. For example, some people started sleeping a lot but then started sleeping very little. This helped the scientists see how different sleep patterns affected people's health. They wanted to see the long-term effects of sleep.
The study found that people who had sleep habits that changed a lot had a higher risk of dying early. This means if you started sleeping too much and then switched to sleeping too little, or the other way around, you were more likely to die sooner. They also found that these people had a higher risk of heart problems. The risks were even higher for some groups of people, like white adults and people with higher incomes.
If you often doze off when you are sitting and reading, watching a movie, talking to someone, sitting quietly after lunch or even during a few minutes of traffic, you may be sleep deprived according to the National Heart, Lung, and Blood Institute. They explain how sleep deprivation can cause issues with learning, focusing and reacting to certain things. The symptoms of sleep deprivation in kids differ a little as they might be overly active and have trouble paying attention to certain things. If you are experiencing sleep issues, make sure to speak to a healthcare professional who will help you identify the issues and direct you towards the treatment or changes you must make. Here are some ways sleep helps your body.
Good sleep allows your heart and blood vessels to heal. This keeps them strong and healthy, reducing the risk of heart problems.
Sleep helps balance your hunger hormones, so you don't feel too hungry. This helps prevent eating too much and keeps your weight healthy.
Proper sleep helps your body use insulin correctly. This lowers the chance of high blood sugar, which can lead to diabetes.
Deep sleep releases growth hormones, helping kids and teens grow. It also repairs body tissues, which is important for everyone.
When you sleep well, your body's defense system gets stronger. This helps you fight off germs and stay healthy.

Endometriosis is a chronic disease affecting about 1 in 10 women worldwide. Diagnosis and treatment remain challenging, particularly for women with severe pain and other complications.
Now, US researchers have developed a targeted nanotherapy that showed promising results against endometriosis in early testing.
Scientists at Washington State University found that the treatment reduced endometriosis lesions, symptoms and pain sensitivity after a single dose in mice.
The findings were published in Advanced Healthcare Materials. Researchers hope to eventually test the treatment in humans.

The drug, niclosamide, was previously used to treat intestinal tapeworm infections in humans and is still used in animals.
Earlier research found that niclosamide could reduce endometriosis lesions and inflammation. However, it is not suitable for long-term use, limiting its potential as a treatment for a chronic condition.
To overcome this, researchers developed a nanotherapy that delivers niclosamide directly to cells associated with endometriosis.
“We found the disease-specific immune cell, and then we had a drug, but we couldn’t target the cell with the drug alone,” said Kanako Hayashi, professor at WSU’s School of Molecular Biosciences.
“So we used this nanocarrier that delivers the drug specifically to the disease site,” Hayashi said.
The team used a nanosized molecule called a dendrimer to bind with niclosamide and deliver it in a more soluble form.
In mice, a single injection reduced the size and number of lesions and lowered pain sensitivity.
“Although we still need to clear multiple phases, this study is telling us the efficacy is strong, and this nanocarrier is stable, so far, for two weeks—and we think we can go longer,” Hayashi said.
If the treatment remains stable for longer periods, researchers believe it could potentially be given less frequently. Hayashi said a monthly injection could be possible in the future, but this would depend on further testing.

Not yet. The treatment has only been tested in mice and must undergo further safety and efficacy testing before human trials.
Researchers also do not yet know whether it would ultimately be given as an injection or IV infusion.
Endometriosis affects an estimated 190 million women worldwide. It occurs when tissue similar to the lining of the uterus grows outside the uterus.
It can cause severe pelvic pain, painful periods, pain during sex and infertility. Symptoms are sometimes dismissed as a “bad period,” contributing to delays in diagnosis.
There is currently no cure, although treatments can help manage symptoms.
Treatment depends on symptoms, disease severity and fertility goals.
Hormonal medicines can help control pain and disease activity but may cause side effects and can affect fertility while being used.
Painkillers, including non-steroidal anti-inflammatory drugs, may help manage discomfort.
Laparoscopic surgery can remove lesions and endometriotic cysts and may help restore pelvic anatomy. It can also improve fertility in some women, although the disease can recur.
Lifestyle measures such as regular exercise, stress management and dietary changes may also support symptom management.

Lung development of the fetus depends on the physical and genetic health of the parents.
At birth, breathing begins with air from the environment, containing oxygen and other gases, and is influenced by known and unknown forces of nature. The air then passes through well-developed nostrils, which regulate the air temperature and prevent foreign bodies from entering the body and help protect against diseases.
Breath travels through the nasal passages, sinuses, pharynx (throat), larynx (voice box), trachea (breathing tubes), bronchi, small airways, air sacs, interstitial membrane, into thin-walled blood vessels that transport oxygen and collect gases and other substances to be expelled from the body.
The diaphragm, the muscle that separates the lungs from the abdomen, is the most powerful breathing apparatus.
The lungs in the early stages of life undergo dramatic changes from newborn→ infancy→ childhood→ puberty→ teenage→ adults→ middle age→ seniors. Factors influencing lung health risks keep changing with age, depending on genetics, environment & external factors.
The lungs and airways perform non-respiratory functions of protecting the body against harmful insults, both from within and external threats, and it also protects against insults received from other organs of the body. The lungs have a powerful defense mechanism protecting the body and also have hormonal, physical, and immunological defense mechanisms.

A small lump in the neck is easy to overlook, especially when there is no pain. In many cases, it has a simple explanation, such as an infection or a swollen lymph node. Thyroid nodules are also common, and most of them are not cancerous.
The thyroid is a small gland at the front of the neck. When cancer develops in the thyroid, a lump or swelling may sometimes be the first noticeable change. It may remain painless, which is one reason people tend to wait before getting it checked.
The way a lump changes over time can provide an important clue. A swelling that suddenly becomes larger, feels harder, remains in place for several weeks deserves attention.
Other changes can include persistent hoarseness, difficulty swallowing, a feeling of pressure in the neck or, less commonly, difficulty breathing. Swollen lymph nodes on the side of the neck can also occur. These symptoms are not specific to thyroid cancer and may be related to other causes, but they should not be dismissed if they persist.

A doctor will first examine the neck and assess the size and location of the swelling. An ultrasound is often used to look more closely at the thyroid and any nodules present.
If a nodule has features that call for further investigation, a fine-needle aspiration may be advised. A small sample of cells is taken with a thin needle and examined to determine whether further treatment or monitoring is required.
A painless lump does not automatically mean cancer, and discovering a thyroid nodule is not a reason to panic. At the same time, a swelling that stays for over three weeks, grows or is accompanied by changes in swallowing or voice should be evaluated.
Early assessment can help identify whether the lump is related to the thyroid, an infection or another condition, and whether any follow-up is needed.
