The skin is an outward reflection of our internal health. Dull skin, for instance, may indicate dehydration, a lack of essential nutrients, or an inconsistent skincare routine. As the most visible organ, the skin also provides insight into the health of the body tissues it protects. It's more than just an aesthetic aspect—it’s a window into overall well-being. Disorders of the gut, blood, hormones, and even the heart can manifest as skin issues, such as rashes.

Ayurveda has long emphasized the importance of skincare. In today's fast-paced world, a proper skincare routine is indispensable, not only for physical health but also for mental well-being. While modern skincare offers a plethora of products, many come with side effects. Ayurveda provides a holistic solution, addressing skincare concerns naturally and sustainably.

Ayurvedic Skin Types

Ayurveda classifies skin types based on the three doshas:

1. Vata (Wind) Vata

Vatadominant individuals tend to have dry, rough skin that wrinkles easily if not properly moisturized.

• Oil application: Pinda taila is ideal for moisturizing dry skin.
• Internal care: Mahatiktaka ghrita helps reduce dryness.
• Face pack: Use Eladi churna or Navara rice face packs to moisturize and reduce dryness.
• Hydration: Drink plenty of water to combat dehydration.

2. Pitta (Fire) Pitta

Pitta dominant individuals often have oily skin, prone to acne, rosacea, and discoloration.

• Oil application: Nalpamaradi tailam is best for pitta skin.
• Cleansing: Wash your face with Eladi or Manjishtadi water to reduce discoloration and tone the skin.
• Cooling elements: Use aloe vera, turmeric, and sandalwood to combat inflammation, pimples, and redness.

3. Kapha (Water and Earth)

Kapha skin tends to be cold, oily, and prone to pimples, whiteheads, and water retention.

• Avoid oil-based creams: Use face masks regularly to control sebum production.
• Therapy: Dhara with Triphala churna or Eladi water is beneficial.
• Oil application: Eladi coconut oil is ideal.

Panchakarma for Healthy, Radiant Skin

Panchakarma therapies help detoxify the body and enhance skin health. Key treatments include:

Abhyanga and Pizhichil: These therapies pacify doshas, enhance skin tone, and act as natural moisturizers.

Navara Kizhi: Improves skin softness and complexion.

Snehapana: Internal lubrication with ghee to maintain hydration and promote a natural glow.

Ubtan: A traditional herbal paste for exfoliation and nourishment.

Lepam: Herbal poultices to soothe inflammation and heal skin conditions.

Garshan/Udwarthanam: Dry brushing to stimulate circulation and exfoliate dead cells.

Shirodhara: Oil pouring therapy to relax, de-stress, and improve sleep quality.

Panchakarma Detox: A five-step detoxification process to cleanse the body and rejuvenate the skin.

Internal Routine for Healthy Skin

1. Stay hydrated and drink 2–3 liters of water daily. Incorporate water-rich fruits and vegetables like watermelon, cucumber, and oranges. Herbal teas with ginger, lemon, or chamomile aid digestion and promote glowing skin.

2. Follow a balanced diet based on your Ayurvedic prakriti and elevated doshas. Include whole grains, dairy, seasonal fruits, and antioxidant-rich foods like tomatoes, broccoli, and papaya. Avoid fried, refined, and processed foods, as well as excessive sugar, salt, and red meat.

3. Regular exercise promotes blood circulation, detoxification, and skin nourishment. Activities like yoga, walking, or dancing improve oxygen flow, flushing out toxins and revitalizing the skin.

4. Maintain a consistent sleep schedule. Restful sleep stimulates growth hormones, promoting collagen and elastin production, which keeps skin firm and youthful.

Small, gradual adjustments in daily routines can lead to healthier, more radiant skin. Embrace an Ayurvedic skincare regimen, complemented by panchakarma therapies, to achieve sustainable and natural skin health.

Using amphetamines, cocaine and cannabis can significantly increase your risk of having a brain stroke particularly among younger adults, according to a new University of Cambridge analysis

The findings highlight how recreational drug use may contribute to a preventable health risk, especially among people under the age of 55.

Megan Ritson, a stroke genetics researcher at the University of Cambridge and lead author said the results provide strong evidence linking certain drugs to stroke risk.

“These findings provide compelling evidence that drugs like cocaine, amphetamines, and cannabis are causal risk factors for stroke,” Ritson noted.

A stroke occurs when blood flow to part of the brain is interrupted. This can happen when a blood vessel becomes blocked by a clot, known as an ischemic stroke, or when a blood vessel bursts and causes bleeding in the brain, known as a hemorrhagic stroke. Both types can lead to serious brain damage and can be life threatening.

Amphetamines Associated With The Highest Risk

When researchers combined data from eight previous studies, they found that recreational amphetamine use was associated with more than double the risk of stroke across all adult age groups. For individuals under the age of 55, the increase was even greater. In this group, amphetamine use was linked to nearly triple the risk of stroke compared with people who do not use the drug.

Across all age groups, the analysis found that amphetamine use increased the risk of ischemic stroke by 137 percent and hemorrhagic stroke by 183 percent. These figures reflect relative risk, meaning the probability of stroke is higher among users compared with non users.

Cocaine Shows A Similar Pattern

The analysis showed that cocaine use nearly doubled the risk of stroke of any kind and more than doubled the risk of hemorrhagic stroke. Additional genetic investigations were conducted alongside the main analysis to better understand whether the relationship might be causal rather than simply linked to other lifestyle factors.

Eric Harshfield, a genetic epidemiologist at the University of Cambridge, said the findings suggest the drugs themselves may play a direct role. “Our analysis suggests that it is these drugs themselves that increase the risk of stroke, not just other lifestyle factors among users,” Harshfield said.

Cannabis Linked To Smaller But Significant Risk

Among people under the age of 55, cannabis use was linked to a 14 percent increase in stroke risk. Although the increase is lower than that associated with stimulant drugs, researchers say it remains important because cannabis is widely used.

Opioids Showed No Clear Association

A Preventable Health Risk

The researchers also note that many of the studies included in the analysis relied on participants reporting their own drug use. Because of this, other lifestyle factors could potentially influence the results. Further research will be needed to better understand the biological mechanisms involved and how different patterns of drug use may affect stroke risk. Still, scientists say the evidence now available provides an important foundation for future public health strategies.

“These findings give us stronger evidence to guide future research and public health strategies,” Ritson said.

In cities that rarely slow down, sleep is often the first thing people compromise. Late-night work calls, endless notifications, streaming platforms, and the pressure to stay productive are quietly cutting into the hours meant for rest. On World Sleep Day, health experts are raising concerns about a growing issue among urban professionals: sleep debt.

Sleep debt refers to the cumulative effect of regularly getting less sleep than the body needs. While it may seem harmless to sleep five or six hours on busy weekdays, the missing hours slowly add up and begin to affect both the body and the mind.

According to Dr. Manav Manchanda, Director and Head of Respiratory, Critical Care and Sleep Medicine at Asian Hospital, the problem is far more serious than many people realize.

“Sleep is not a luxury. It is a biological necessity,” he says. “Chronic sleep deprivation affects almost every system in the body. When people repeatedly ignore their sleep needs, it leads to hormonal imbalance, weakened immunity, mood disturbances and reduced productivity.”

The Urban Lifestyle And The Rise Of Sleep Debt

Urban professionals often pride themselves on staying busy. But long work hours, tight deadlines, frequent travel, and social obligations have created an environment where sleep is seen as negotiable.

Many people assume that sleeping longer on weekends can make up for lost rest during the week. However, doctors say the body does not recover so easily.

Sleep debt builds gradually when the body consistently receives less rest than it requires. Over time, this pattern begins to interfere with natural biological rhythms, making it harder for the body to regulate energy, focus and emotional balance.

When Lack Of Sleep Starts Affecting Performance

One of the earliest signs of sleep debt is a noticeable decline in cognitive function. People who do not get enough sleep often experience brain fog, poor concentration, irritability and slower decision-making.

In high-pressure professions such as corporate management, media, finance and technology, this can significantly impact work performance. Errors, missed details and reduced productivity can all stem from insufficient rest.

Dr. Manchanda explains that the effects are not limited to mental fatigue. “When the body does not get enough sleep, it disrupts several important systems including metabolism, hormone regulation and immune function,” he says.

The Health Risks Behind Chronic Sleep Loss

Persistent sleep deprivation can gradually increase the risk of serious health conditions. Experts link long-term sleep debt with obesity, diabetes, high blood pressure and heart disease.

Mental health can also be affected. Poor sleep patterns are associated with increased anxiety, mood swings and symptoms of depression.

“Over time, sleep debt can significantly increase the risk of metabolic disorders and cardiovascular diseases,” Dr. Manchanda adds. “People often underestimate how deeply sleep influences overall health.”

The Role Of Screens And Digital Habits

Another major reason behind sleep debt is digital dependency. Many professionals spend their evenings scrolling through smartphones or watching online content late into the night.

This habit exposes the eyes to blue light, which interferes with the release of melatonin, the hormone responsible for regulating the sleep cycle. As a result, the body struggles to recognize when it is time to wind down.

Building Better Sleep Habits

Doctors say improving sleep hygiene is one of the most effective ways to reduce sleep debt. Maintaining a consistent sleep schedule, limiting screen exposure before bedtime and avoiding caffeine late in the evening can help regulate sleep patterns.

Creating a calm sleeping environment and engaging in stress-relieving activities such as exercise or meditation may also improve sleep quality.

Experts believe workplaces also have a role to play. Encouraging better work-life balance and reducing after-hours communication can allow employees to prioritize rest.

On World Sleep Day, the message from doctors is clear. In a culture that celebrates constant productivity, sleep remains one of the most powerful tools for protecting long-term health and mental well-being.

Every night when we fall asleep, the brain does not simply power down. Instead, it moves through a carefully organized biological rhythm known as the sleep cycle. During this process, the body shifts through different stages of sleep that help repair tissues, regulate emotions and strengthen memory.

Scientists have spent decades studying these stages using brain recording tools such as electroencephalography, or EEG. This technique measures electrical activity in the brain using small sensors placed on the scalp. By analyzing these signals, researchers can identify exactly which stage of sleep a person is in.

According to multiple National Institutes of Health studies, sleep occurs in repeating cycles of two kinds: Non Rapid Eye Movement sleep (NREM) and Rapid Eye Movement sleep (REM). A typical cycle lasts about 90 minutes and the brain repeats this cycle four to six times each night.

The Structure Of The Sleep Cycle

NREM sleep includes three stages, moving from light sleep to deep sleep. After these stages, the brain enters REM sleep, which is strongly linked to dreaming and emotional processing.

Scientists believe the repeated movement through these stages helps the brain complete different biological tasks. Some stages repair the body while others reorganize information learned during the day.

Neuroscientist Jan Born, University of Tübingen, whose research focuses on sleep and memory, explains that deep sleep is essential for memory formation. His work shows that during sleep, the brain transfers information from short term storage to long term memory systems.

Stage 1: The Transition Into Sleep

The first stage, called NREM Stage 1, is the moment when the brain begins shifting from wakefulness into sleep. This stage typically lasts only a few minutes. Muscles relax, breathing slows slightly, and eye movements become slower. Brain waves also begin to change.

When we are awake, the brain produces fast electrical signals called beta waves. As sleep begins, the brain switches to slower patterns known as theta waves.

Because this stage is very light, a person can wake up easily. Many people experience sudden muscle twitches known as hypnic jerks, which can feel like the sensation of falling.

Stage 2: Stable Light Sleep

NREM Stage 2 is where true sleep begins. This stage usually makes up the largest portion of the night. During this stage, the heart rate slows and body temperature drops slightly, preparing the body for deeper rest.

Brain recordings show unique patterns called sleep spindles and K complexes. Sleep spindles are short bursts of rapid brain activity. A 2011 Neuroscience study found that these spindles are closely connected with communication between the hippocampus and the cortex, two brain regions involved in memory formation.

Researchers believe these bursts help the brain protect sleep from outside disturbances while also strengthening memories formed earlier in the day.

Stage 3: Deep Sleep And Physical Recovery

NREM Stage 3, often called deep sleep or slow wave sleep, is the most restorative stage. In this stage, the brain produces very slow electrical patterns called delta waves. These waves indicate that the brain is in its deepest resting state.

Deep sleep is when the body carries out important repair work. Growth hormone is released, muscles recover from physical activity and the immune system strengthens. According to Mark Wu, a sleep expert and neurologist at Johns Hopkins Medicine, this stage is also strongly linked to the restoration of energy and overall physical recovery.

It is difficult to wake someone during deep sleep. If they are awakened, they may feel disoriented or extremely groggy for several minutes.

REM Sleep And Dreaming

Most vivid dreams occur during this stage. At the same time, the body temporarily shuts down most muscle activity, a phenomenon called REM atonia, which prevents people from physically acting out their dreams. REM sleep typically makes up about 25 percent of total sleep time during a normal night.

Researchers have found that REM sleep plays an important role in emotional processing and learning. Multiple neuroscience studies suggest that REM sleep helps regulate emotions and supports the strengthening of neural connections involved in learning new skills.

A recent study reported by Harvard Medical School even found that reduced REM sleep may be associated with an increased risk of dementia later in life, highlighting the importance of this stage for long term brain health.

Why These Stages Matter

Experts in sleep science often emphasize that the quality of sleep matters just as much as the number of hours. When sleep is disrupted, the brain may not spend enough time in the stages that support learning, recovery, and emotional balance.

On World Sleep Day, this growing body of research reminds us that sleep is not wasted time. It is one of the most powerful biological systems the body has for restoring both the brain and the body every single night.
