A new study published in The Lancet Digital Health suggests that biological age of different organs could predict a person's risk of diseases such as cancer, dementia, and heart disease than their actual chronological age. The research analyzed long-term data from Whitehall II study, which had been followed by over 10,000 British adults for more than 35 years.

The blood plasma samples were collected between 1997 and 1999 from participants between ages 45 to 69. Researchers have now examined a follow up data from 6,235 participants, who were by then aged 65 to 89. This was done to see how aging of specific organ may correlate with the development of diseases over two decades.

What Organs Were Studied?

The study measured the biological age of nine key organs, including:

• Heart
• Blood vessels
• Liver
• Immune system
• Pancreas
• Kidneys
• Lungs
• Intestines
• Brain

The researchers were able to find that different organs aged at different rates in different people. In many of the cases multiple organs showed signs of faster aging within the same individual. What is important to note is that those with accelerated aging in certain organs had a higher risk of developing 30 out of the 40 age-related diseases the study had tracked.

Organ Aging And Disease Risk

Some organ-disease connections were expected—people with rapidly aging lungs were more likely to develop respiratory diseases, and those with aging kidneys had an increased risk of kidney-related conditions. However, the study also found less obvious associations.

For example, individuals with fast-aging kidneys were more prone to diseases in other organs, such as the liver and pancreas. Additionally, multiple fast-aging organs were linked to an increased risk of kidney disease.

One of the most surprising findings was that dementia risk was not best predicted by an aging brain but rather by the immune system’s biological age. This suggests that factors such as chronic inflammation and immune health may play a critical role in neurodegenerative diseases.

What Is Organ Specific Blood Tests?

The study also highlights the important of the potential of developing blood tests that could assess the biological age of specific organs. Unlike previous complex methods that measured the organ health, this new approach could make things simple to detect early signs of disease.

The leader author of the study Mika Kivimaki, who is also a professor at the University College London's Faculty of Brain sciences pointed out that such tests could be helpful when it comes to guiding personalized healthcare. In a news release, Kivimaki said, "They could advise whether a person needs to take better care of a particular organ and potentially provide an early warning signal that they may be at risk of a particular disease."

The study reinforces the idea that aging does not affect all organs equally and that looking beyond chronological age could offer better insights into disease prevention. By understanding which organs are aging more rapidly, medical professionals may be able to recommend targeted interventions for individuals at higher risk of specific conditions. Future advancements in organ-specific blood testing could revolutionize how we detect and manage age-related diseases, potentially leading to more personalized healthcare strategies.

Everyone knows that using sunscreen is one of the most important steps for protecting the skin from harmful sun rays, but dermatologists explain that it isn't the only thing you should do to keep your skin healthy. Other daily routines are also important for minimizing sun damage and maintaining healthy skin over time.

Protecting The Skin Barrier

Skin is a protective barrier for the body but constant exposure to the sun, pollution, heat and unhealthy lifestyle habits can make this barrier vulnerable.

Once the skin barrier is damaged, the skin is more susceptible to tanning, pigmentation, dryness, sun ageing and other sun damage.

Moisturising Supports Skin Health

Using a moisturiser every day is a very simple, yet effective habit. A good moisturiser is one that doesn't contain any scents and will support the barrier function of the skin, thereby preventing unwanted water loss from the skin.

Wet and plump skin is resistant to the environment and sun's rays.

Antioxidants Help Fight Sun Damage

Antioxidants are also a best practice for dermatologists. Antioxidants prevent the damage to skin cells by free radicals created by UV exposure, pollution etc.

This protection can help minimize issues like hyperpigmentation, uneven skin tone and premature ageing. Consuming foods that contain antioxidants (such as fruits, vegetables and nuts) can help keep skin healthy on the inside.

Stay Hydrated For Healthier Skin

Next, hydration is crucial. It's important to keep drinking enough water all day long to keep the skin supple and to allow the skin to repair itself. Moisture also contributes to skin's healing from environmental stress.

Physical Sun Protection Matters

Sun protection is also of great importance. Wearing hats or caps, using umbrellas, and wearing clothing that protects against the sun's rays can minimize direct exposure to the sun.

All these are simple actions that serve as a physical barrier and prevent sunburn and long term damage to the skin, particularly between 10 a.m. and 4 p.m. These simple steps provide a physical barrier and reduce the risk of sunburn and chronic skin damage, particularly in the peak hours of 10 a.m. to 4 p.m.

Gut Health And Skin Connection

Another focus has been on the connection between gut health and healthy skin, as experts recognize how crucial the role of the gut is in maintaining healthy skin.

Probiotics can potentially improve the gut-skin axis and aid in the healing process and alleviate inflammation in the body. The better the gut environment, the better the skin will be able to recover and the less the exposure to the sun will age the skin.

Collagen May Support Skin Repair

Some people can use collagen supplements as an added benefit. Collagen is involved in supporting the dermis, the skin's structural component. Keeping collagen high can help promote skin repair and healing mechanisms.

Doctors say while sunscreen is important, long-term skin protection can be achieved through a variety of healthy habits, proper nutrition, hydration and physical sun protection measures, which must be followed daily.

We tend to think of our eyes as easy – they just "see", and we go about our day. But the fact is, your eyes are adapting a lot, focusing and straining all the time, far more than you realize. Many of these moments are utterly unremarkable, but they build up gradually into a tiredness, a dryness and a long-term strain.

We see many people who are shocked to find out how hard their eyes had been working long before any symptoms appeared. Here are six common situations that deserve a whole lot more attention – and care – from your eyes.

Staring at Your Phone First Thing in the Morning

Having a quick glance at notifications before even leaving bed requires your eyes to adjust to a small, bright screen in the dark. This quick change puts a load on the eye muscles and can make them tire before your day has really started.

Long Hours in Front of a Computer

Working, studying, and hopping from meeting to meeting: extended hours in front of the screen drastically lower your usual blink rate. Less blinking equals less lubrication, which is why so many people are dry, irritated and have blurry vision by the afternoon.

Driving at Dusk or Night

Night driving is one of the most challenging visual jobs humans undertake, given low light, incoming headlights and the need to constantly change focus between the road, mirrors and dashboard. Your eyes are working tirelessly to shift between bright and dim situations in fractions of a second.

Reading Fine Print

Poorly lit restaurant menus, pharmaceutical labels, or the small text on a contract all demand that you focus hard at close range, frequently in less-than-ideal illumination. As we get older, this type of near-focus strain is very common since our natural ability to focus declines.

Switching Between Multiple Screens

Glancing from your laptop to your phone to a television and back again, it makes your eyes refocus at multiple distances. It is easier, but this continual flipping is more tiring than looking at one screen for the same period of time.

Stepping Out Into Bright Sunlight Into Bright Sunlight

Your eyes work hard to adjust while you move from a dim room into harsh daylight — or vice versa. Over time, repeated exposure to glare without the correct protection (such as sunglasses) can add unneeded strain.

None of these moments feel dramatic on their own, but together, they represent a significant daily workload for your eyes. The good news is that habits such as the 20-20-20 rule, correct lighting, regular blinking and eye check-ups can go a long way in reducing this concealed tension. We believe that awareness is the beginning of healthy eyesight.

If you are suffering frequent eye strain, dryness or fuzzy vision, it may be time to schedule a full eye exam. Your eyes work harder than you realize – let’s give them the attention they deserve.

During those rainy days, children are forced to remain indoors, and this can lead to reduced physical activity during the monsoon. Constant immobility can lead to compromised immunity, weight gain, mood changes, and impact the child’s overall development. Parents must see to it that the child remains active during the rainy season.

Why Monsoon Keeps Children Indoors

Monsoon brings relief from the summer heat, but it also means that the child will not be able to play outdoors. So, the waterlogged grounds, heavy rainfall, and concerns about infections often keep children indoors for extended periods.

Occasional indoor play is not problematic, but weeks of reduced physical activity can take a toll on the child's physical, mental, and emotional well-being.

Health Risks of Reduced Physical Activity

Regular outdoor play for at least an hour can aid in the child's growth and development. Children can opt for running, cycling, playing sports such as cricket, football, basketball, badminton, and improve bone and muscle health. If children remain indoors, they can become less active and spend a lot of time watching television, using mobile phones, or playing video games.

This increase in screen time can contribute to weight gain, acidity, muscle and joint pain. If the child is unable to play outdoors, then this can impact their immunity. During the monsoon, children may become more prone to infections if physical activity decreases and dietary habits worsen. Combined with seasonal viral illnesses, this can lead to frequent coughs, colds, and fatigue.

Reduced exposure to sunlight during the monsoon may also contribute to lower Vitamin D levels in some children. Vitamin D plays an important role in bone development, muscle strength, and immune health.

The Benefits of Outdoor Play for Children

The benefits of outdoor play for children: Outdoor play helps children relieve stress, socialize, and gain confidence. Staying indoors for long periods can lead to boredom, irritability, loneliness, reduced concentration, and mood changes.

Some children may become less energetic, sleep poorly, or show increased dependence on screens for entertainment. So, children should make sure to exercise indoors and improve their well-being.

Tips for Parents to Keep Children Active Indoors

Tips for parents: Parents can make sure that the child does indoor physical activities such as dancing, skipping, yoga, stretching exercises, obstacle courses, and active games to stay fit. Encouraging children to participate in household activities and family games can also reduce excessive screen time.

The child should also have a nutritious diet, stay hydrated, follow a structured sleep routine, and avoid junk food. So, this monsoon, make sure that your child stays healthy and strong!
