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.

While research shows women need more sleep than men due to brain function, hormones, and multitasking, females around the globe are struggling to get enough sleep, according to experts.

A 2016 study by the Sleep Research Centre at the UK’s Loughborough University found that women needed 20 minutes more sleep because of multitasking and performing more complex brain tasks during the day.

But, the American Academy of Sleep Medicine (AASM), revealed that an estimated 30 percent of women fail to get sufficient sleep.

Hormones, mood disorders, and caregiving responsibilities, coupled with professional pressures and stress, are the major reasons driving up insomnia and other sleep issues among women.

“Women around the world face a higher burden of sleep difficulties because their sleep cycles are tightly interlinked with hormonal shifts that occur throughout life,” Dr. Janhvi Siroya Shah, Sleep Specialist from the University of Bern, Switzerland, told HealthandMe.

Gender Gap In Sleep: Why Women Sleep Less

The gender gap in sleep is real, as revealed by the recent ResMed Global Sleep Survey 2026, which showed that 56 percent of women get a good night's sleep only four days or fewer per week, compared to 50 percent of men.

Women were also 48 percent more likely to report problems falling asleep than men (42 percent). More than 50 percent of women felt waking up not feeling rested for 1-2 nights per week or more, compared to 46 percent of men.

The study flagged stress or anxiety as the biggest barrier to consistent, quality sleep (39 per cent), followed by work-related responsibilities (37 per cent) and household duties (31 per cent) among women.

Speaking to HealthandMe, Dr. Kirti Kadian, from the Department of Pulmonary Critical Care & Sleep Medicine at AIIMS Bhopal, said: “Women experience disproportionate sleep challenges globally, largely because their bodies undergo repeated physiological transitions that influence how sleep is regulated.”

The experts cited the main reasons as

• fluctuations during menstruation,
• pregnancy,
• postpartum recovery
• menopause.

All these factors can alter mood regulation, increase nighttime alertness, and disrupt the architecture of sleep itself.

Dr Kadian said that hormonal fluctuations across the life course -- especially during the menopausal transition -- can affect circadian rhythm, airway stability, pain sensitivity, and the nervous system’s response to stress.

“When these biological changes coincide with external stressors, such as multitasking, emotional labor or caregiving demands, women become far more vulnerable to insomnia and unrefreshing sleep,” Shah said.

The prevalence of sleep disorders increases from about 16–42 percent in pre-menopause to around 39–47 percent in peri-menopause and up to 35–69 percent in post-menopause, indicating that sleep disturbances become more common as women progress through different reproductive stages.

“Declining levels of estrogen and progesterone can disrupt the body’s sleep regulation and trigger symptoms like hot flashes and night sweats, while reduced melatonin may make it harder to fall and stay asleep,” Dr. Kadian explained.

In addition, certain medical conditions that are more common in women, such as thyroid disorders, anemia, and autoimmune diseases, can also negatively affect sleep and overall health.

How Poor Sleep Affects Women

Poor sleep also significantly affects both physical and mental health, increasing the risk of

• metabolic disorders,
• cardiovascular disease,
• weakened immunity,
• persistent fatigue,
• reduced concentration,
• irritability,
• anxiety,
• depression.

How Women can Improve their Sleep

The Harvard Medical School suggested that to get a better sleep cycle women should:

• Create a sleep sanctuary by removing the television, computer, smartphone or tablet, from the bedroom.
• Cut down or limit afternoon naps to 20 to 30 minutes
• Avoid caffeine after noon
• Get regular exercise, but not within three hours of bedtime.

Every year on March 20, World Oral Health Day is observed to raise awareness about the importance of caring for your mouth at every stage of life. This means starting from birth through later years. However, a visit to dentist is usually the last thing anyone plans when they think of a doctor's visit. Dental visits happen only when extraction or something bigger is involved. More often than not people ignore a follow up or a regular dental checkup to maintain oral health. Why so?

In a previous interview with Health and Me Lt Gen Dr Vimal Arora, the Chief Clinical officer at Clove Dental, who has 40 years of experience as a dentist and also served in the Indian Army explained how oral health is not just about a pretty smile. He explained that many do not plan a regular visit to a dentist because the problems that pertains to oral health do not seem "life threatening".

However, Dr Arora told Health and Me that oral health can in fact be the first way to know if anyone is prone to a chronic disease.

Early Signs Of Disease Your Mouth Can Reveal

“There is now scientific evidence, published in top medical journals, that shows how oral infections can significantly worsen pre-existing systemic diseases,” says Dr. Arora. This isn’t just a theory — it’s a medically established fact.

Take diabetes, for instance. People with gum infections often find it harder to control their blood sugar levels. “If you're suffering from diabetes and you have a gum infection, your diabetes will not be well controlled. In fact, it may worsen,” he adds. The same applies to heart diseases. Oral infections can increase inflammation in the body, potentially triggering or worsening cardiovascular problems.

This is concerning especially for those people who may already be managing conditions like hypertensions, arthritis, or respiratory illness. Poor oral health can actually sabotage their efforts to stay stable.

“Your tongue is a true mirror of your oral and general health,” says Dr. Arora. The correlation therefore goes beyond just gums and teeth. Dentists are trained to detect early signs of systemic disorders simply by examining the tongue's color, coating and texture.

A pale tongue might indicate iron deficiency, while a coated tongue could be a sign of digestive issues or a viral illness. “Sometimes, we ask patients if they've had their blood work done, based purely on what we see on their tongue,” he adds. In some cases, dentists can even detect undiagnosed diabetes or early signs of nutritional deficiencies.

What Mother's Oral Health Can Predict About Their Babies

Dr. Arora also highlights the overlooked risks that pregnant women face when they neglect their dental hygiene. “If you are pregnant and suffer from periodontitis or even gingivitis — essentially poor gum health — you are at risk of having a preterm or low-birth-weight baby,” he says.

This isn’t just theory; it’s a well-documented risk in obstetric dentistry. Pregnant women are encouraged to get dental check-ups not just for themselves, but for the health of their unborn child.

Despite these evidences, oral health remains one of the most neglected aspects of personal healthcare. Dr. Arora believes this is partly due to a lack of awareness and the perception that dental problems are not "serious enough."

“People often wait until they’re in pain before they see a dentist, but by then, the damage might already be affecting other parts of the body,” he says. Preventive check-ups, regular cleaning, and treating gum infections early on can go a long way in improving not just oral health, but overall wellness.

Most people reach for sunscreen when heading to the beach or stepping out for a long day in the sun. But skincare experts say sun protection should not be limited to vacations or outdoor activities. Sunscreen is meant to be part of a daily skincare routine.

This often raises a common question. If you are staying indoors all day, do you still need sunscreen?

Dermatologists say the answer depends on your surroundings and daily habits.

Sunlight can still reach you indoors

Many people assume that staying inside completely protects their skin from sunlight. But this is not always true.

Dr Khushboo Jha, MBBS, MD, Chief Dermatologist Consultant at Metro Hospital and Founder of One Skin Clinic, explains that sunlight entering through windows can still affect the skin.

“While standard window glass blocks most UVB rays, which cause sunburn, UVA rays can still pass through. These rays penetrate deeper into the skin and are linked to long term concerns such as premature aging, uneven pigmentation and loss of skin elasticity,” she says.

These UVA rays are often overlooked because they do not cause immediate redness or burning like UVB rays. However, over time they can lead to visible signs of skin aging and pigmentation.

When sunscreen indoors becomes important

Dermatologists say sunscreen indoors is particularly useful for people who spend long hours near windows or in well lit spaces.

Dr Jha notes that individuals who work near windows, sit in sunlit rooms or spend time driving during the day may still be exposed to sunlight. “Even short periods of daily exposure to sunlight over time can contribute to cumulative skin damage,” she explains.

In such situations, applying sunscreen in the morning can offer an added layer of protection. A broad spectrum sunscreen with at least SPF 30 is generally recommended.

This approach is especially relevant for people working in offices with large windows or those who frequently commute during daylight hours.

What if you are away from windows?

Experts also say sunscreen use indoors is not always equally necessary for everyone.

If you spend most of the day inside a room with minimal natural light and away from windows, your exposure to ultraviolet radiation becomes much lower.

Dr Jha says that in such cases the urgency of frequent sunscreen reapplication becomes less important. The risk of sun related skin damage is significantly reduced when there is little to no direct daylight entering the space.

This means sunscreen indoors should not be treated as a strict rule but rather as a flexible part of skincare based on lifestyle and environment.

What about blue light from screens?

Another topic that often comes up is blue light exposure from digital devices such as phones, laptops and tablets.

Some studies suggest that prolonged exposure to visible light may contribute to pigmentation, especially in individuals with deeper skin tones. However, dermatologists point out that the amount of blue light from electronic screens is much lower than what we receive from natural sunlight.

Dr Jha says the effect of digital screens on the skin is still being studied, but compared to sun exposure, the impact remains minimal.

A practical approach to daily skincare

Dermatologists suggest viewing sunscreen as a preventive skincare habit rather than a rigid rule.

Dr Jha recommends incorporating sunscreen into your morning routine, particularly if your day includes stepping outdoors or spending time in naturally lit environments.

In simple terms, if daylight reaches your workspace or you plan to go outside later in the day, applying sunscreen in the morning is a small step that can help protect your skin over time.
