Walking is more than just a way to move from point A to point B—it may be a simple yet powerful way to boost your mental health. While it is constantly known to impact your physical well-being, research has found that it can also help you tackle depression. According to the study, adults walking 5,000 or more steps daily experienced fewer depression symptoms compared to those who walked less. Mental Health benefits increased with more steps. For instance, research participants, who walked over for at least 7,500 steps every day saw a 42% reduction in depression symptoms.
Interestingly, even a modest boost in daily steps made a difference. Adding just 1,000 extra steps daily was linked to a lower risk of depression. Another analysis from the same study highlighted that people who hit 7,000 steps or more each day were less likely to develop depression than those who walked less. Experts have said that walking may reliably reduce depression by measurable amounts while also potentially lowering the risk of developing depression.
For their research, experts reviewed data from 33 studies involving over 96,000 adults to explore the link between walking and reduced depression symptoms. The studies used wearable devices like pedometers and smartphones to measure participants' step counts, typically over a week. The meta-analysis found that walking not only reduced depression symptoms but also served as a practical, low-pressure alternative to structured exercise, especially for those who might find more intensive workouts intimidating.
However, the researchers acknowledged some limitations. People who walked more might already feel better, and the study didn’t explore other factors, such as the potential benefits of walking in nature or with others, which could further improve mood.

Sleep takes up nearly one-third of a person’s life, yet many still wonder what really happens while we rest. Until the mid-20th century, scientists believed sleep was simply a time when the body and brain shut down.
Research now shows that sleep is far from passive, it’s an active, restorative process essential for mental and physical health. As Johns Hopkins neurologist and sleep expert Dr. Mark Wu explains, the brain remains deeply engaged during sleep, performing vital tasks that influence memory, mood, and overall well-being.
Experts say the human sleep cycle has four main stages that repeat throughout the night. The first three make up non-rapid eye movement (non-REM) sleep, while the fourth is REM sleep, the stage most closely linked with dreaming.
In the first stage of non-REM sleep, the brain and body begin to shift from wakefulness to rest. Brain activity slows, muscles relax, and it is common to experience small, sudden twitches.
During the second stage, the body’s temperature drops slightly, and breathing and heart rate slow. Brainwaves continue to decelerate, though quick bursts of activity may still appear as the brain processes and stores information.
The third stage marks deep sleep, which is the most restorative phase. Here, the body fully relaxes, and the heart rate, breathing, and brain activity reach their lowest levels. This stage is crucial for waking up feeling refreshed and for healing and repair processes throughout the body.
The final stage is REM sleep, which begins about 90 minutes after you fall asleep. It starts short, roughly 10 minutes, but lasts longer with each cycle. During REM, the eyes move rapidly beneath the eyelids, breathing quickens, and heart rate and blood pressure rise to near waking levels. This is when most dreaming occurs. Interestingly, as people age, the amount of REM sleep they experience gradually decreases.
According to Dr. Wu, two main forces govern sleep: the circadian rhythm and the body’s sleep drive.
The circadian rhythm acts as the body’s internal clock, controlled by a cluster of brain cells that respond to light and darkness. This rhythm triggers the release of melatonin at night and halts it when morning light appears. People who are completely blind often struggle with sleep because their brains can’t register these light cues properly, as per the John Hopkins Study.
The sleep drive works much like hunger. The longer you stay awake, the stronger your urge to sleep becomes. Unlike hunger, though, your body can override your willpower, if exhaustion sets in, it can force sleep to happen, even during daily activities or while driving. In extreme fatigue, brief “microsleep” moments lasting just a few seconds can occur without a person realizing it. However, taking long naps later in the day can reduce this natural sleep pressure, making it harder to fall asleep at night.
Anyone who has felt mentally sluggish after a sleepless night knows how strongly rest affects the brain. Adequate sleep is key to brain plasticity—the ability to learn, adapt, and form memories. Without it, the brain struggles to retain new information and perform cognitive tasks. Scientists also believe that deep sleep allows the brain to clear out toxins that build up during waking hours, improving long-term brain health.
Sleep impacts far more than the mind. Poor sleep can worsen conditions like depression, high blood pressure, migraines, and even seizures. It weakens the immune system, leaving the body more vulnerable to infection. Metabolism also suffers, as just one night without enough rest can temporarily throw the body into a prediabetic state.
As Dr. Wu explains, “There are countless ways sleep supports health.” From mental clarity to physical repair, the hours we spend asleep are some of the most important for keeping the body and brain functioning at their best.

When COVID-19 first emerged, it was largely seen as a respiratory illness. Over time, doctors discovered that the virus can affect nearly every major organ, including the heart, kidneys, liver, and skin. While cough, fever, and fatigue remain common signs, some people also develop unusual skin reactions. So, can COVID-19 actually lead to rashes? Here’s what experts have found.

While cough, fever, and fatigue remain common signs, some people also develop unusual skin reactions. So, can COVID-19 actually lead to rashes? Here’s what experts have found.
Skin changes linked to COVID-19 are not among the most common symptoms, but they do occur. These rashes may appear on the neck, mouth, or toes and are often caused by inflammation in the body, as per Health website. They can look like flat or raised patches, small round spots, or itchy bumps. In some people, these rashes appear while they’re infected; in others, they show up weeks later.
Researchers believe COVID-related rashes are connected to how the virus interacts with the body’s ACE2 receptors, which are found in the skin. When the virus attaches to these receptors, it can trigger the release of inflammatory proteins called cytokines. This inflammation may lead to skin irritation, itchiness, or lesions.
One of the most recognized skin signs of the virus, “COVID toes,” resembles chilblains, which are cold-weather sores. They appear as pink, red, or purple patches, sometimes with swelling or blistering. This condition is seen more often in younger people and may occur even after other symptoms fade.
Hives tend to appear suddenly and can spread across any part of the body. They’re itchy, raised, and may come and go within hours or days.
Some people develop eczema-like rashes on the neck, chest, or trunk during or after COVID-19. The patches can be itchy and vary in color depending on skin tone—pink on lighter skin and brown, gray, or purple on darker skin.
COVID can also cause soreness or peeling inside the mouth or on the lips. The area may feel dry, irritated, or scaly as it heals.
These small, itchy bumps can be filled with fluid (vesicular) or solid (papular). They may appear anywhere on the body and are often linked with ongoing inflammation.
This condition begins with a single large patch on the chest, back, or abdomen, followed by smaller spots that form a tree-like pattern. Though harmless, it can take several weeks or months to fade.
These rashes appear as dark, bruise-like spots caused by small blood vessel damage under the skin. The color may range from red and purple to brown or black, depending on skin tone.
The duration depends on the type of rash and the person’s immune response. Most clear up within 2 to 12 days, but some, especially in long COVID cases, may persist for weeks.
Many rashes resolve without any special treatment. To relieve itching or pain, applying mild hydrocortisone cream can help. For more severe or persistent cases, doctors may recommend:
Your doctor will determine the safest treatment depending on the type of rash and overall health.

It is a common theme for people to feel down and sad in winter. However, why do shorter, colder days often bring on feelings of loneliness and gloom? There is a biological reason behind it. As the days get shorter, many people feel a dip in energy or mood, but for millions, this signals Seasonal Affective Disorder (SAD), which is a serious form of depression that shouldn't be ignored. Experts from West Virginia University (WVU) caution that SAD symptoms are very similar to major depressive disorder and must be taken seriously.
SAD is much more than just feeling down when it gets dark. It's a genuine type of depression most often seen during the winter months, especially in places far north where daylight is scarce. The basic problem is simple: less natural light hits your eyes. This drop in sunlight confuses your brain's chemistry.
It messes with two vital brain chemicals: serotonin, which helps stabilize your mood, and melatonin, which controls when you sleep and wake up. This lack of light also throws off your body's internal clock, called the circadian rhythm. When all these elements get disrupted, it triggers feelings of low energy and depression.
SAD involves a cluster of symptoms that persist and significantly interfere with your daily life. The pattern is usually predictable: symptoms begin in the fall, peak in the winter, and disappear by spring. Symptoms often include:
The risk of SAD is higher among younger people, women, and those with a family history of mood disorders.
Because Seasonal Affective Disorder is highly predictable, experts advise starting preventative treatments early in the fall. Seeing a healthcare provider is essential to determine the best plan and timing for treatment, rather than waiting for severe symptoms to appear later in winter.
This involves sitting daily before a special light box emitting 10,000 lux of bright white light. Doing this for 30 to 60 minutes each morning is the most common and effective treatment for SAD, as it helps correct the imbalance caused by reduced sunlight exposure.
This form of talk therapy teaches you practical skills to manage negative thinking patterns and behaviors linked to depression. CBT helps individuals reframe their outlook on winter and build effective coping mechanisms to reduce the impact of SAD symptoms.
In certain situations, a healthcare provider may prescribe antidepressant medication to help regulate mood-affecting brain chemicals like serotonin. This is often considered alongside light therapy or counseling, especially if symptoms of depression are severe or persistent.
Simple daily habits are powerful tools. Regular exercise boosts mood and energy, while maintaining a consistent sleep schedule keeps your body's internal clock stable. These practical steps offer significant support alongside clinical treatments.
