Fasting may reset your body, but can it reset your mind? The new trend of dopamine fasting claims it can. And wait, there's more. This trend also works against dopamine resistance, implying that things that did not make you happier before will now do. You see, dopamine is a part of the brain's reward system and plays an important role in your pleasure reception. While this neurotransmitter is not directly linked to an individual's happiness, it triggers feelings of satisfaction, motivation and pleasure.

However, a person can also reach a stage of dopamine resistance if they continue to indulge in activities that trigger its frequent or constant release. In this case, the individual stops feeling the impact of this neurotransmitter and thus, does feel good or happy.

So does dopamine fasting work?

Dopamine fasting is a practice where individuals limit their exposure to activities or stimuli that typically provide a surge of dopamine. The idea behind dopamine fasting is to reset or recalibrate the brain's reward system. This is usually done by abstaining from gratifying things or experiences like social media, junk food, and even sex. Proponents of dopamine fasting argue that continual overstimulation from digital devices, social media, and easily accessible indulgences has numbed our brain's reward pathways. By regularly denying ourselves these dopamine triggers, the idea claims, we might restore our ability to acquire fulfilment from life's basic pleasures.

How Does Dopamine Imbalance Affect Your Mental Health?

Having low levels of dopamine can make you less motivated and excited about things. In Parkinson's disease, there is not enough dopamine in the areas of the brain important for movement. This leads to problems with muscle stiffness and movements such as walking.

The symptoms of a dopamine imbalance depend on what is causing the problem. They include physical symptoms such as:

• muscle cramps, spasms or stiffness
• digestion problems, such as constipation or reflux
• pneumonia
• trouble sleeping
• moving or speaking more slowly than usual

• feeling tired and unmotivated, or sad and lacking hope
• having low libido (sex drive)
• hallucinations (experiencing something that's not real)

How Can I Adjust My Dopamine Levels?

Adjusting dopamine levels is complicated, as it is involved in many different roles in the brain. Your doctor won't measure your dopamine levels directly, and there is no simple test to measure it. Your symptoms will be the clues that tell your doctor if you have too much or not enough dopamine. They will then prescribe medicines to adjust your dopamine level, based on your symptoms, and make adjustments based on how your body responds and how you feel.

When John Cena started noticing blurry vision, he assumed it was simply part of getting older. But the worsening eyesight was also accompanied by redness, itchiness and crusting around his eyes.

“I had a lot of redness and itchiness, and every once in a while, waking up with eye crusties and stuff. At the same time, given my age — I'm 49 now — my vision was going a little bit, so I just figured it was par for the course. But because my vision was going, I needed to see if I needed glasses or prescriptions.”

Until then, Cena had delayed getting his eyes checked. He believed that the symptoms were caused by bright lights, excessive screen time or ageing.

However, an eye examination gave him a surprise. Cena learned that his symptoms were caused by Demodex blepharitis, a condition he says he had never heard of.

“Diagnosed with Demodex blepharitis, which I didn't even know existed.”

What Are Demodex Mites?

Demodex mites are tiny, eight-legged organisms that live naturally on human skin, particularly around hair follicles. Measuring just 0.15 to 0.4 millimeters, they are invisible to the naked eye but are present on the skin of almost every adult.

These microscopic mites feed on sebum (the skin's natural oil) and dead skin cells, helping remove accumulated debris under normal conditions.

How Do Demodex Mites Work?

Demodex mites are most active at night. They emerge from hair follicles after sunset because ultraviolet (UV) light is harmful to them. While people sleep, the mites feed, crawl and reproduce on the skin's surface.

They are also believed to be stimulated by melatonin, the hormone that helps regulate sleep, creating a unique relationship between humans and these naturally occurring organisms.

When Can Demodex Mites Become A Problem?

Although harmless in small numbers, Demodex mites can cause problems if they multiply excessively—a condition known as demodicosis.

According to Dr. Richard Locksley, professor of medicine at the University of California, San Francisco, an overgrowth of Demodex mites can contribute to:

• Rosacea
• Blepharitis (eyelid inflammation)
• Acne-like breakouts
• Itchy, inflamed skin

People with weakened immune systems are particularly vulnerable because their bodies may be less able to control mite populations. In addition, inadequate sleep may increase oil production, providing more nourishment for the mites.

Should You Be Worried?

For most healthy people, Demodex mites are a normal part of the skin microbiome and are not considered harmful. Problems generally arise only when their numbers increase significantly.

To help reduce the risk of overgrowth:

• Wash your face every night with a gentle, non-comedogenic cleanser to remove excess oil and debris.
• Remove eye makeup and false eyelashes before bed, as these can encourage mite buildup.
• Get adequate sleep, since poor sleep may increase sebum production.
• Consult a dermatologist if you experience persistent redness, itching or inflammation around the eyes or skin.

Common Sports Injuries and How to Prevent Them by Dr Sumit Batra. Whether you're training for a marathon, playing pickleball with friends, or simply trying to stay fit at the gym, being active is one of the best things you can do for your health. But every sport is unique and places different demands on your body. Without the right preparation, even a fun weekend workout can leave you with an injury that keeps you on the sidelines. Often, I see people whose injuries could have been avoided by warming up properly, increasing their training slowly, and paying attention to pain. Many think the pain will go away on its own, but getting it checked early can help prevent bigger problems.

Several types of common sports injuries show up suddenly, while others build up over time. Ankle sprains are among the most common. They usually happen when the foot rolls awkwardly during running, jumping, or changing direction quickly. Simultaneously, Knee injuries are another common problem, especially in sports that involve sudden stops, pivots, or jumps, so the ligaments, cartilage, or tendons around the knee can be affected, making movement painful and unstable.

Muscle strains in the hamstrings and calves often occur when muscles are pushed harder than they're ready for. Skipping a warm-up or increasing the intensity of your workouts too quickly can raise the risk.

Athletes who play cricket, tennis, or volleyball, or who spend long hours swimming, may also develop shoulder pain due to repeated overhead movements. And then there are overuse injuries like tennis elbow, shin splints, and Achilles tendinitis, which develop slowly after repeated stress without enough recovery.

How to Reduce Your Risk

The good news is that most sports injuries can be prevented. Start every workout with a proper warm-up. Just five to ten minutes of light movement and stretching can help prepare your muscles and joints for exercise.

Strength training is equally important. Strong muscles support your joints, improve balance, and help your body absorb the impact of running, jumping, and lifting.

It's also important not to rush your progress. Whether you're preparing for a race or trying heavier weights, increasing the intensity little by little gives your body time to adapt safely.

Recovery deserves just as much attention as training. Good sleep, proper hydration, balanced meals, rest days, and well-fitting sports shoes all play a role in keeping injuries away.

Listen to What Your Body Is Telling You

Always listen to your body—it often gives warning signs before it's too late. Feeling sore after a challenging workout is completely normal. But pain that doesn't improve, swelling, difficulty putting weight on a limb, or restricted movement shouldn't be ignored. Getting the injury checked early often means a quicker recovery and lowers the chances of long-term problems. Sports injuries can happen to anyone, whether you are a seasoned athlete or someone who enjoys staying active on weekends. A little preparation, sensible training, and adequate recovery can go a long way in preventing them. And if something doesn't feel right, don't wait for it to get worse. Early care can make all the difference in getting you back to doing what you love.

Gone are the days when constipation was considered a problem only among older adults. Today, an increasing number of young professionals are experiencing irregular bowel movements, bloating, abdominal discomfort, and a constant feeling of incomplete evacuation. The fast-paced corporate lifestyle, long working hours, unhealthy eating habits, and chronic stress have made constipation a common digestive concern among people in their 20s and 30s.

One of the biggest contributors is a sedentary lifestyle. Many professionals spend eight to ten hours sitting at a desk, with little time for physical activity. Regular movement helps stimulate bowel function, and a lack of it can slow down digestion. Another common cause is poor dietary habits. Skipping breakfast, relying on processed or fast foods, and consuming inadequate amounts of fibre can significantly affect bowel health.

Hydration also plays a vital role. Busy schedules often lead people to consume more coffee or tea while neglecting water intake. Dehydration makes stools harder and more difficult to pass, increasing the risk of constipation. Stress is another major factor. Deadlines, work pressure, and poor sleep can disrupt the communication between the brain and the gut, affecting normal bowel movements. Ignoring the natural urge to pass stools due to meetings or travel can further worsen the condition over time.

The good news is that constipation can often be managed through simple lifestyle changes. A balanced diet rich in fibre from fruits, vegetables, whole grains, legumes, and nuts helps add bulk to stools and promotes regular bowel movements. Drinking at least two to three litres of water daily keeps stools soft and easier to pass.

Regular physical activity is equally important. Even a brisk 30-minute walk, stretching during work breaks, or choosing stairs over elevators can improve gut motility. Maintaining a consistent toilet routine, preferably after breakfast, and responding promptly to the body's natural urge can also help establish healthy bowel habits.

Stress management should not be overlooked. Practising yoga, meditation, deep breathing exercises, or simply ensuring adequate sleep can positively influence digestive health. Limiting excessive consumption of processed foods and caffeinated beverages can also reduce the risk of constipation.

While occasional constipation is usually not a cause for concern, persistent symptoms lasting more than three weeks, severe abdominal pain, blood in the stool, unexplained weight loss, or constipation alternating with diarrhoea should never be ignored. These could indicate an underlying medical condition that requires evaluation by a gastroenterologist.

Healthy digestion is closely linked to overall well-being and productivity. By adopting healthier daily habits and paying attention to digestive health, young professionals can prevent constipation, improve their quality of life, and maintain better physical and mental performance at work.
