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.

How Was The Study Done?

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.

Sleep Deprivation And Its Effect On The Body

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.

Repairs Your Heart

Good sleep allows your heart and blood vessels to heal. This keeps them strong and healthy, reducing the risk of heart problems.

Controls Hunger

Sleep helps balance your hunger hormones, so you don't feel too hungry. This helps prevent eating too much and keeps your weight healthy.

Manages Blood Sugar

Proper sleep helps your body use insulin correctly. This lowers the chance of high blood sugar, which can lead to diabetes.

Supports Growth

Deep sleep releases growth hormones, helping kids and teens grow. It also repairs body tissues, which is important for everyone.

Boosts Immunity

When you sleep well, your body's defense system gets stronger. This helps you fight off germs and stay healthy.

Parkinson’s disease is characterized by slowness of daily activities, rigidity, and tremors with gait issues, commonly seen after the age of 45-50 years.

It is two times more common in men than women, though clinical features, response to the treatment, and prognosis are different in women as compared to men. From subtle early signs to how the condition develops over time, gender can shape the Parkinson’s journey in important ways.

Women usually experience Parkinson’s disease at a later age, but with faster progression of symptoms as compared to men. There is a need for more research in this space; however, we will try to shed light on these differences in Parkinson's trajectories in men and women based on available evidence.

Why Is Parkinson’s Less Common In Women?

Estrogen, a group of primary female sex hormones, is neuroprotective and protects dopaminergic neurons in women; women also have a higher baseline reserve of dopaminergic neurons. Hence, Parkinsonism is less common in women.

In the post-menopausal period, once this estrogen-related neuroprotective effect disappears, Parkinson’s symptoms progress rapidly. Motor symptoms emerge later in women with tremors, rigidity, and gait disturbances being more common and severe. Freezing of gait and postural instability with falls are more common in women.

Differences In Motor vs Non-Motor Symptoms

Non-motor symptoms like pain, fatigue, autonomic disturbances, sleep disorders, constipation, and mood disorders, including depression and anxiety, are more common and severe in women. Men with Parkinson’s disease have worse general cognitive abilities; however, women have worse visuospatial abilities.

Women with Parkinson’s receive less social support, lower quality care, attend medical appointments alone, and report more psychological stress. Women have a lower body mass index and higher bioavailability of levodopa, which makes them more susceptible to the side effects of levodopa, such as motor fluctuations and dyskinesia, which entail involuntary movements like fidgeting and writhing.

Why Personalized Treatment Matters

There is a clear need for personalized and tailored treatment. The different and distinctive clinical features in women, like later onset, higher tremors and rigidity, higher dyskinesia and motor fluctuations from drugs, and worse non-motor symptoms, require tailored, sex-specific treatment strategies rather than a “one-size-fits-all” approach.

Clinicians must give importance to the screening and management of non-motor symptoms in women, which are the main factors of their decreased quality of life. Women with this ailment go through longer delays in diagnosis and less access to specialists, highlighting a need for better healthcare access for women.

While HPV vaccines are most known for preventing cervical cancer, a top US doctor says they can also help curb the rising incidence of head and neck cancers.

According to Mikkael A. Sekeres, Chief of the Division of Hematology and Professor of Medicine at the Sylvester Comprehensive Cancer Center at the University of Miami, Human papillomavirus (HPV) — the same sexually transmitted virus that can infect the genital area and lead to cervical cancer — is now the greatest risk factor for head and neck cancer.

Writing in The Washington Post, Sekeres noted that HPV accounts for about 30 per cent of oropharyngeal cancer worldwide.

HPV is believed to be responsible for the recent rise in head and neck cancers, which include malignancies affecting the mouth and throat (oral cavity and pharynx), voice box (larynx), sinuses and nasal cavities, and salivary glands.

Sekeres said the US records about 60,000 new cases of head and neck cancers each year, while the global incidence is expected to rise by 30 per cent by 2030.

What Are The Risk Factors?

The expert noted that men develop oral cavity and pharynx cancers at approximately 2.5 times the rate of women.

Major risk factors include:

• Tobacco use, including smoking, secondhand smoke and smokeless tobacco
• Chewing areca nut, also known as betel quid
• Heavy alcohol consumption
• HPV infection

The Centers for Disease Control and Prevention (CDC) estimates that the high-risk HPV subtypes most associated with head and neck cancers are detectable in the mouths of 4 per cent of adults aged 18 to 69.

While a pap test detects early-stage cervical cancer in women, no such test exists for penile, anal, or head and neck cancers in men, which can worsen their survival rate.

HPV Vaccination Best Prevention Strategy

Thus, Sekeres said: “The best way to prevent the most common types of HPV is through vaccination, with two doses of the vaccine recommended for children at age 11 or 12, or starting as early as 9 years and up to age 26 for those who missed it as a child".

He noted that although the vaccine is approved for use up to age 45, it is generally less beneficial after age 26 because many individuals may have already been exposed to HPV. However, doctors can help determine whether vaccination may still be beneficial for adults.

Earlier this year, the European Cancer Organization also urged broader HPV vaccination regardless of gender.

“HPV affects everyone, regardless of gender. It can lead to cancers of the cervix, mouth and throat, anus and penis. This is why universal protection is so important,” the organization said in a social media post.

HPV Vaccine Can Boost Cancer Risk

A 2026 study published in JAMA Oncology found that boys and men who received the HPV vaccine between the ages of 9 and 26 were nearly 50 per cent less likely to develop cancers of the head and neck, esophagus, anus, or penis.

The findings, based on data of more than 510,000 boys and men, highlight the importance of vaccinating all children and adolescents against HPV, said Taito Kitano, first author of the study and a researcher at Nara Prefecture General Medical Center in Japan.

“Children, adolescents, parents and health care workers should be more informed about the expected benefits of the HPV vaccine, not just cervical cancer,” Kitano said.

FIFA has launched a groundbreaking initiative aimed at advancing research and knowledge to boost health and performance of female athletes.

The FIFA Female Health and Performance Project comes ahead of the tenth edition of the FIFA Women's World Cup, which is scheduled to take place in Brazil next year.

The initiative aims to provide specialist, science-based educational resources tailored to the preparation and development of female athletes. It also seeks to close long-standing gaps in understanding the unique health and performance needs of female players, many of whom still lack access to the scientific data needed to support their development and optimize performance.

“FIFA’s aim is to optimize every female footballer’s health, well-being and performance, and to improve knowledge around women and girls in football at every level of the game,” said Sarai Bareman, FIFA’s Chief Women’s Football Officer.

“Collectively, we can do so much more to better support our growing number of female players and ensure they are trained, supported and understood according to their specific needs as women.”

Why Is The Initiative Significant?

A study analyzing 5,261 research articles published in sport and exercise science journals between 2014 and 2020 found that only 34% of study participants were female, while just 6% of sport science research focused exclusively on women.

Only 8% of elite female athletes have sufficient knowledge about how the menstrual cycle may affect training and performance.

Many training methodologies, workload models and performance benchmarks used in sport have historically been derived from male athlete data, requiring female athletes to adapt to systems that may not accurately reflect their physiological characteristics.

What Will The Project Achieve?

The initiative is designed to provide a comprehensive understanding of the female athlete, her individual needs, her environment and the tailored support required to optimize health and performance.

The educational modules cover universal topics in football and elite sport science, including sleep, recovery, strength and conditioning, all examined through the lens of the female athlete.

Female-specific topics such as physiology, pregnancy, postpartum health and menopause are also included.

Four separate learning levels — from “Introduction” to “Integrated” — provide tailored information for a wide range of audiences, from sports professionals to members of the general public.

In addition to improving access to knowledge and education, the initiative aims to break taboos, normalize language, eliminate social stigma, encourage open communication and establish a supportive environment in which female athletes can thrive.

“We need to normalize conversations around female health and embrace this, using it to our advantage instead of ignoring it or being fearful of discussing it,” Bareman added. “It is not a weakness; it is a strength.”

Key areas covered by the project include:

• Female physiology
• Reproductive years
• Menstrual health tracking
• Pregnancy and postpartum health
• Fertility
• Menopause
• Pelvic health
• Nutrition
• Recovery
• Sleep
• Strength and conditioning
• Screening and profiling
• Injury and injury prevention

Who Will Benefit?

Available to all through FIFA’s Training Centre platform, the FIFA Female Health and Performance education modules are the result of collaboration with leading experts to generate, curate and apply the scientific evidence underpinning the program.

All 211 FIFA Member Associations will have access to specialised, peer-reviewed, science-based information through 13 tailor-made educational modules.
