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.

Seychelles Chikungunya Virus Outbreak: The United States warned travelers to be careful if they plan to visit the Seychelles islands anytime soon as it is currently undergoing a chikungunya outbreak. As per the Centers for Disease Control and Prevention (CDC), a 'Level 2' advisory for the island has been issued and travelers have been asked to 'practice enhanced precautions' if they do plan to visit.

Unique Symptoms Of Chikungunya: What Is The Disease?

Chikungunya is a mosquito-borne viral disease transmitted primarily by Aedes aegypti and Aedes albopictus, the same mosquitoes that spread dengue fever. Symptoms typically appear three to seven days after a bite and include sudden fever, severe joint pain, headache, nausea, fatigue, and rash in about half of cases.

However, there are certain unique symptoms of chikungunya. For instance, unlike a Dengue fever, chikungunya leaves lingering effects along with joint pain and fatigue that lasts up to weeks.

Unique Symptoms of Chikungunya: What Are They?

While common symptoms like high fever often >102 degree F is common there are other symptoms too, which includes:

• Headache
• Muscle pain
• Fatigue
• Joint Swelling

• Some unique symptoms of this disease includes neurological complications such as rare instances that could lead to encephalitis or the inflammation of the brain, meningitis, or severe nerve issues like Guillain-Barré syndrome.

• Ocular symptoms include red eyes like conjunctivitis, eye pain, or temporary vision problems.

• Unique symptoms could also include bleeding, while it is more common in Dengue, rare bleeding from gums and nose could occur in Chikungunya.

• Other unique symptoms may include chronic and persistent symptoms like joint pain that does not subside after the initial week and lasts for months or even years.

• Other symptoms include cardiovascular and respiratory issues and skin manifestation, which could go beyond the common rash. Some patients may experience vasculitis-like skin lesions.

Unique Symptoms of Chikungunya: How Long Does It Last?

Chikungunya symptoms usually occur with in 3 to 7 days after a bite. However, the symptoms could often last long. While fever could subside in a day or two, chronic symptoms especially like joint pain and muscle pain could last for months. Weakness too could persist.

Unique Symptoms Of Chikungunya: Outbreak In Seychelles Led To US Issuing Travel Advisory

A Level 2 travel advisory has been issued, which means the travelers are expected to practice enhanced precautions as compared to a Level 1 advisory that only asks travelers to practice usual precautions.

In more serious cases, Level 3 advisory is issued that asks travelers to reconsider non-essential travel, whereas a Level 4 advisory asks travelers to avoid all travel.

As CDC issues travel advisory, here is what travelers are expected to do:

• Travelers are expected to protect themselves by preventing mosquito bites, which includes using insect repellent, wearing long-sleeved shirts and pants, and staying in places where air conditioning or that have screens on the windows and doors
• The CDC also tells travelers to get vaccinated for those who are visiting the area affected by a chikungunya outbreak
• If a traveler is pregnant, they are asked to reconsider travel to affected area, especially if they are closed to delivering their baby. Mothers infected around the time of delivery can pass the virus to their baby before or during delivery. Newborns infected in this way or by a mosquito bite are at risk for severe illness, including poor long-term outcomes
• If someone has a fever, joint pain, headache, muscle pain, joint swelling, or rash during or after the travel, they must seek medical care

Why do some relationships feel effortless and magnetic, while others slowly unravel despite our best intentions? According to neuroscientist Andrew Huberman, the answers lie deep within our early childhood experiences and the intricate wiring of the brain.

In a recent episode of Huberman Lab titled “Essentials: The Science of Love, Desire & Attachment,” Huberman explores how biology and psychology work together to shape the way we connect, commit, and sometimes drift apart. What makes the conversation compelling is how it bridges hard science with very human emotions.

Our First Bonds Shape Our Love Stories

Huberman begins with a powerful idea: the way we love as adults often echoes how we were loved as children.

He refers to the landmark “Strange Situation” experiment by psychologist Mary Ainsworth. In this study, toddlers were briefly separated from their caregivers and then reunited. Researchers closely observed how the children reacted. Some felt secure and soothed upon return. Others were anxious, avoidant, or distressed.

These early attachment patterns, Huberman explains, frequently resurface in adult romantic relationships. A securely attached child may grow into a partner who trusts and communicates well. An anxious child may become someone who fears abandonment. An avoidant child may struggle with emotional closeness.

The hopeful part? These patterns are not destiny. Awareness allows change. Once people recognize their emotional blueprint, they can reshape it.

Love Is Not in One Spot in the Brain

Romantic connection is not housed in a single “love center.” Instead, multiple brain regions activate in sequence to create desire, attraction, empathy, and long term bonding.

Huberman clears up a common myth about dopamine. Many people think of it as the pleasure chemical. In reality, it is more about motivation and pursuit. Dopamine fuels craving and drives us toward a person we find compelling. It is the chemical that makes you check your phone, wait for a message, or feel a rush at the thought of someone.

But desire alone does not sustain love.

For deeper attachment, empathy circuits come into play. The prefrontal cortex and the insula are especially important. The insula helps us sense our internal bodily state, a process known as interoception. It allows us to feel our own emotions while tuning into someone else’s. This shared emotional awareness strengthens bonds.

The Role of “Positive Delusion”

One of the most fascinating ideas Huberman discusses is what he calls “positive delusion.” For long term stability, the brain benefits from believing that your partner is uniquely special. This slight bias, almost a romantic illusion, reinforces commitment.

It is not about ignoring flaws. It is about genuinely feeling that this person, out of billions, holds a singular place in your emotional world. Biologically, this strengthens attachment pathways.

Why Relationships Fall Apart

Huberman also references research from the Gottman Lab at the University of Washington. Decades of data reveal four behaviors that predict relationship breakdown: criticism, defensiveness, stonewalling, and contempt.

Stonewalling happens when one partner emotionally withdraws and stops responding. But the most toxic behavior is contempt. Researchers have described it as acid to a relationship because it corrodes trust and shuts down empathy. Once contempt takes root, the neural circuits that support connection begin to weaken.

In the end, love is both chemistry and choice. Our brains may set the stage, but awareness, empathy, and daily behavior determine whether attachment deepens or quietly falls away.

For decades, scientists believed the gradual loss of the Y chromosome in ageing men did not matter much. But a growing body of research now suggests otherwise. Studies show that losing the Y chromosome in blood and other tissues is linked to heart disease, cancer, Alzheimer’s disease and even shorter lifespan. The crux is simple but striking. As men age, many of their cells quietly lose the Y chromosome, and this loss may be shaping men’s health in ways we are only beginning to understand.

Aging And The Disappearing Y Chromosome

Men are born with one X and one Y chromosome. While the X carries hundreds of important genes, the Y is much smaller and contains just 51 protein coding genes. Because of this, scientists long assumed that losing the Y in some cells would not have serious consequences beyond reproduction.

However, newer genetic detection techniques tell a different story. Research shows that about 40 percent of men aged 60 have some cells that have lost the Y chromosome. By age 90, that number rises to 57 percent. Smoking and exposure to carcinogens appear to increase the likelihood of this loss.

This phenomenon, known as mosaic loss of Y, does not occur in every cell. Instead, it creates a patchwork in the body where some cells carry the Y chromosome and others do not. Once a cell loses the Y, its daughter cells also lack it. Interestingly, Y deficient cells seem to grow faster in laboratory settings, which may give them a competitive edge in tissues and even in tumors.

Why Would Losing The Y Matter?

The Y chromosome has long been viewed as mainly responsible for male sex determination and sperm production. It is also uniquely vulnerable during cell division and can be accidentally left behind and lost. Since cells can survive without it, researchers assumed it had little impact on overall health.

Yet mounting evidence challenges that assumption. Several large studies have found strong associations between loss of the Y chromosome and serious health conditions in older men. A major German study reported that men over 60 with higher levels of Y loss had an increased risk of heart attacks. Other research links Y loss to kidney disease, certain cancers and poorer cancer outcomes.

There is also evidence connecting Y loss with neurodegenerative conditions. Studies have observed a much higher frequency of Y chromosome loss in men with Alzheimer’s disease. During the COVID pandemic, researchers noted that men with Y loss appeared to have worse outcomes, raising questions about its role in immune function.

Is Y Loss Causing Disease?

Association does not automatically mean causation. It is possible that chronic illness or rapid cell turnover contributes to Y loss rather than the other way around. Some genetic studies suggest that susceptibility to losing the Y chromosome is partly inherited and tied to genes involved in cell cycle regulation and cancer risk.

However, animal research offers stronger clues. In one mouse study, scientists transplanted Y deficient blood cells into mice. The animals later developed age related problems, including weakened heart function and heart failure. This suggests the loss itself may directly contribute to disease.

A New Chapter In Men’s Health

So how can such a small chromosome have such wide ranging effects? While the Y carries relatively few genes, several of them are active in many tissues and help regulate gene activity. Some act as tumor suppressors. The Y also contains non coding genetic material that appears to influence how other genes function, including those involved in immune responses and blood cell development.

The full DNA sequence of the human Y chromosome was only completed recently. As researchers continue to decode its functions, the message for men’s health is becoming clearer. Ageing is not just about wrinkles or grey hair. At a microscopic level, the gradual disappearance of the Y chromosome may be quietly influencing heart health, brain health and cancer risk.

Understanding this process could open new doors for early detection, personalized risk assessment and targeted therapies that help men live longer and healthier lives.
