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 too much or too little dopamine in some parts of the brain is linked to some mental illnesses including depression, schizophrenia and psychosis. Having too much dopamine is linked to being aggressive and having trouble controlling your impulses. Dopamine imbalances are also related to ADHD and addiction.

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

They can also include mental or psychological symptoms such as:

• 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.

Smoking has been long recognized as one of the worst habits a person can have, and Dr Jeremy London agrees with this statement. Dr. London, a cardiovascular surgeon, in a recent interview with Mel Robbins revealed that his number one advice as a heart doctor is to avoid smoking.

“I cannot come up with one single thing that does as much damage to every organ in the body as smoking cigarettes. And look, it's incredibly addictive and I know that and I pass no judgment because I know how difficult it is.”

He explained that in his practice he has dealt with chronic smokers for years and still believed that it is the single most dangerous thing one can do to themselves.

How Does Smoking Affect Other Organs?

Emphasizing how this one habit affects all organs in our body, Dr London mentioned the well-known link between lung cancer and smoking.

However, there are many more chronic diseases associated with the rest of the body that can develop due to smoking apart from lung conditions, according to the American Lung Association.

Here is what you should keep an eye out for:

Heart Disease

Smoking damages your heart and narrows your arteries, restricting vital oxygen flow. While heart disease rates dropped as smoking decreased, it remains a top killer. Stopping tobacco use helps clear your blood vessels and protects your body’s most important organ.

Asthma

Asthma makes moving air in and out of your lungs a constant struggle. Cigarette smoke irritates these airways, triggering sudden and dangerous attacks. For the millions of people living with asthma, smoking makes the condition much harder to manage daily.

Reproductive Health

For women, smoking reduces fertility and makes it much harder to get pregnant. It also increases the risk of life-threatening ectopic pregnancies. Protecting your reproductive health starts with avoiding tobacco to ensure a safer environment for a potential future pregnancy.

Vision Loss

Smoking can actually lead to permanent blindness by damaging the internal structures of your eyes. It is the primary cause of age-related macular degeneration in older adults. Quitting helps preserve your sight and prevents cataracts from forming as you age.

Lung Cancer

Smoking is the leading cause of lung cancer, accounting for nearly 90 percent of all cases. Although medical treatments have improved, the five-year survival rate remains low. Quitting is the most effective way to lower your risk of this deadly disease.

Chronic Obstructive Pulmonary Disease

Chronic Obstructive Pulmonary Disease (COPD) is a severe lung condition that makes breathing difficult and exhausting. It often starts with mild shortness of breath but can eventually leave people housebound. Smoking causes up to 90 percent of cases, significantly limiting your physical activity and independence.

Other Cancers

Apart from lung, smoking also causes at least twelve different types of cancer, including liver, stomach and colon cancer. For survivors, continuing to smoke greatly increases the chance of a second cancer developing. Avoiding tobacco is the best way to improve overall survival rates.

Fasting for three hours before bed can significantly improve heart health and reduce the risk of coronary artery disease (CAD) as well as other chronic conditions, an Arteriosclerosis, Thrombosis, and Vascular Biology study suggests.

While many believe that diet plans such as intermittent fasting or time-restricted eating can help reduce their weight, researchers at Northwestern University have found that not eating three hours before going to sleep can reduce overnight blood pressure by nearly four percent, heart rate by five percent and strengthen overall heart rhythms.

This can help reduce overall strain on the heart which lowers risks for conditions like hypertension and CAD. Additionally, the scientists also discovered a drop in blood sugar levels, improved glucose tolerance and insulin sensitivity.

Participants who underwent glucose tests also showed better insulin release which tend to stabilize during the day. Additionally, an improved heart rate also lowered nighttime cortisol, which helped in metabolic balance.

Dr. Phyllis Zee, director of the Center for Circadian and Sleep Medicine and chief of sleep medicine in the department of neurology at Feinberg and corresponding author said of the results: "It's not only how much and what you eat, but also when you eat relative to sleep that is important for the physiological benefits of time-restricted eating."

The study authors also noted: "Extending overnight fasting duration by three hours in alignment with sleep improved cardiometabolic health in middle-aged/older adults by strengthening coordination between circadian- and sleep-regulated autonomic and metabolic activity.

"This sleep-aligned time-restricted eating approach represents a novel, accessible lifestyle intervention with promising potential for improving cardiometabolic function."

Coronary Artery Disease: The Silent Killer

Despite being as a common heart disease, coronary artery disease (CAD) develops over years and has no clear signs and symptoms apart from a heart attack. The illness begins due to a buildup of fats, cholesterol and other substances known as plaque in and on the artery walls.

Over time, this can cause narrowing or blockage of the coronary arteries and block the supply of oxygen-rich blood to heart which can lead chest pain (angina), shortness of breath and ultimately, heart attacks.

Typically, those above the age of 45, having a biological family member with heart disease, lack of sleep, smoking, consuming saturated fats along with other autoimmune diseases such as lupus and rheumatoid arthritis can increase the risk of developing CAD.

Treatment options may include medicines and surgery. Eating a nutritious diet, getting regular exercise and not smoking can help also prevent CAD and the conditions that can cause it.

Nearly one in 10 Indian adults suffer from CAD and about two million people die from the disease annually. Apart from this, about 18 to 20 million American adults aged 20 and older are also affected about the disease.

Strokes: A Rising Crisis In India

Additionally, heart strokes are also one of the leading global health burdens, causing significant deaths and disability worldwide, including in India. Compared to Western countries, stroke also tends to occur at a younger age and is associated with a higher case fatality rate in the country.

One in seven stroke patients in India are young adults aged below 45 years, with hypertension leading as the major risk factor, according to a study by the Indian Council of Medical Research (ICMR).

The Global Burden of Disease Study 2021 identified hypertension, air pollution, tobacco smoking, high cholesterol, increased salt intake, and diabetes as the leading risk factors of stroke.

Incidence of stroke is increasing significantly in low- and middle-income countries (LMICs), especially in India, due to population growth, aging, and greater exposure to risk factors.

Quitting smoking is one of the most important steps a person can take to improve their health. But research suggests that women face unique challenges that make it harder to stop smoking and remain nicotine-free as compared with men.

According to the Centers for Disease Control and Prevention, about 10 percent of women in the US currently smoke cigarettes. Each year, while many attempt to quit, maintaining long term abstinence remains difficult for a large number of smokers.

Scientists say these differences are not about motivation and women are usually just as willing to quit smoking as men. In many cases they are even more likely to seek help through smoking cessation programs, counseling or medical treatment.

However, the challenge lies in a combination of biological, psychological and social factors that can make nicotine addiction behave differently in women.

Nicotine Works Differently in Women’s Bodies

One of the biggest reasons for the difference is biological as women process nicotine differently than men.

Research shows that women tend to metabolize nicotine faster. This means nicotine leaves the body more quickly, which can lead to stronger withdrawal symptoms and more frequent cravings. Jean Perriot, MD, an addiction specialist at the Émile Roux Dispensary in France, says this biological difference can affect treatment.

Even though doctors sometimes worry about giving women too much nicotine replacement therapy, such as patches or gum, biological measurements often show that many women actually receive too little nicotine replacement, which can make treatment less effective.

Hormones also play a role in smoking behavior. Studies suggest that cravings may increase when estrogen levels are high and decrease when progesterone levels rise. These hormonal shifts occur naturally during the menstrual cycle and may influence when quitting attempts are most successful.

Stress And Emotions Can Trigger Smoking

Psychological factors also contribute to smoking patterns among women. Previous research has found that women are more likely to use cigarettes to cope with stress, anxiety and negative emotions. Smoking can temporarily affect brain chemicals linked to mood, which may reinforce the habit.

Dr Nancy Rigotti, director of the Tobacco Research and Treatment Center at Massachusetts General Hospital who specializes in smoking cessation for many years notes that emotional triggers such as stress or depression can strongly influence smoking behavior among women.

Social and economic pressures may also increase vulnerability to tobacco use. Historically, the tobacco industry has targeted women with marketing campaigns that connect smoking with weight control, independence or attractiveness. Public health experts say these messages can shape attitudes about smoking and reinforce addictive behaviors.

Smoking Habits And Weight Concerns

Nicotine addiction is not only chemical but also behavioral. The physical actions involved in smoking, such as holding a cigarette or inhaling smoke, can become powerful habits. Sensory cues such as the smell of tobacco can also reinforce the urge to smoke.

Behavioral research suggests these cues may have a stronger influence for some women, which can make quitting harder even when nicotine dependence is treated.

Furthermore, nicotine can suppress appetite, leading may to pick up smoking to manage body weight. Studies show that women are more likely than men to experience increased cravings for high sugar or high fat foods after quitting smoking. They also tend to gain slightly more weight on average which can make some women hesitant to quit or more likely to relapse.

Treatments Work Differently for Women

Scientists further note that smoking cessation treatments can affect men and women differently.

Research suggests nicotine replacement therapy may need to be carefully adjusted because of faster nicotine metabolism in women. Some medications used to help people quit smoking may also have different effects.

For example, studies suggest the medication varenicline may cause more side effects in women, while the drug bupropion may be somewhat less effective for female smokers.

On the other hand, behavioral treatments appear to work well for many women. Cognitive behavioral therapy, which helps people understand and change unhealthy habits, may be slightly more effective for women than men. Women are also more likely to try complementary approaches such as meditation, yoga or hypnosis when attempting to quit smoking.

Toward More Personalized Quit Strategies

Experts say these findings highlight the need for smoking cessation programs that consider sex based differences. Combining medications with behavioral counseling, stress management strategies, and lifestyle support may improve success rates. Doctors may also consider life stages such as pregnancy, menopause, or hormonal changes when planning treatment.

Exposure to secondhand smoke is another concern. Studies show women are often more likely to be exposed to tobacco smoke at home or in shared environments. Some research also suggests women may face higher risks of certain tobacco related diseases even at lower levels of smoking.

Understanding these differences can help doctors design better quitting strategies. Scientists say the goal is not simply to encourage people to quit smoking, but to provide the right tools so that quitting becomes more achievable for everyone.
