My child’s fever was 102 F° and I was worried. I made my daughter comfortable, gave her some liquids and applied a lemon wrap around the calves. Fifteen minutes later the fever was down by a degree and a half to 100.5 F.° I continue to check how my child was doing. I touched her forehead and noted that it became slightly cooler. By the next day the fever had broken, and my daughter felt much better.
Most people are worried when they or their children have a fever, as it may indicates an illness. They quickly rush to take a Tylenol or other medications to reduce the fever and discomfort. We question whether this almost automatic response to inhibit fever is the best approach. It is important to note that fever is seldom the cause of illness; instead, fever is the body’s response to support healing by activating the immune system so that it can fight the infection. In most cases, the fever may last for a day or two and then disappears. Watchful waiting does not mean, not seeking medical help. It means careful monitoring so that the fever does not go too high versus automatically taking medications to suppress the fever.
Although fever can be uncomfortable, in most casest is not something to be feared. Rather than suppressing it, allow the fever to run its course, as fevers can improve clinical outcomes. Research findings indicate that individuals who experience an increase in body temperature (i.e., a fever) have higher survival rates following infection (Repasky et al., 2013). Spontaneous remissions of cancer—altogether a rarer event—have been observed repeatedly in connection with febrile infectious diseases, especially those of bacterial origin (Kienle, 2012). Late in 19th and early 20th century, Prof Coley observed that in patients who had wound fever or fevers that were induced by injecting bacterial toxins, their cancer sometimes disappeared (Kienle, 2012). In the early 20th century, inducing fever with injecting a bacterial toxin became an acceptable and somewhat successful treatment strategy for treating cancer (Karamanou, et al., 2013; Kendell et al, 1969). It was even a fairly successful treatment for neuro-syphilis before advent of antibiotics. Malaria-induced fevers were used as a treatment for neurosyphilis from the 1920s until the 1950s,—the spiking fevers associated with malaria killed the bacteria that caused the syphilitic infection (Gambino, 2015). The fever therapy slowly disappeared as antibiotics (penicillin), chemotherapy and radiation tended to be more effective.
Although suppressing fever with medication may make you feel more comfortable, and in some cases allow a child to go to day care, it may be harmful. Dr. Schulman and colleagues at the University of Miami Leonard M. Miller School of Medicine demonstrated in a randomized controlled study that, among similar patients admitted to the ICU, the risk of death was seven times higher for those who received fever-reducing medication compared to those who did not (Schulman et al., 2005).(Schulman et al., 2005).
Fever reducing medication may in rare cases lead to complications. For example, aspirin may cause stomach irritation and ulcers as well as being cofactor in Reye’s syndrome (Temple, 1981; Schrör 2007). While acetaminophen (also known as paracetamol), often given to young children, may increase the risk of allergic rhinitis and possibly asthma by the age of six (Caballero, et al., 2015; McBride, 2011). As McBride point out, there appears to be a correlation between acetaminophen use and asthma across all groups, ages and location. This correlation even holds up for mothers who took acetaminophen during pregnancy as their children have increased risk for asthma by age six.
As Bauer and colleagues (Bauer et al., 2021) point out: “Paracetamol (N-acetyl-p-aminophenol (APAP), otherwise known as acetaminophen) is the active ingredient in more than 600 medications (Excedrine) used to relieve mild to moderate pain and reduce fever. Research suggests that prenatal exposure to APAP might alter fetal development, which could increase the risks of some neurodevelopmental, reproductive and urogenital disorders. Pregnant women should be cautioned at the beginning of pregnancy to: forego APAP unless its use is medically indicated. This Consensus Statement reflects our concerns and is currently supported by 91 scientists, clinicians and public health professionals from across the globe.”
Finally, we wonder whether active fever suppression during childhood might condition the immune system not to initiate a fever response through the process of classical conditioning, thereby reducing the immune system’s overall competence. This could be a contributing factor to the increasing rates of allergies, immune disorders, and the earlier onset of certain cancers (Gorter & Peper, 2011). Specifically, if a person begins to develop a fever and medication was used to reduce it, over time the fever response may become automatically inhibited through covert classical conditioning.
Simple home remedy when having a fever?
- Practice watchful waiting. This means monitoring the person and only use medication to reduce fever if necessary. When in doubt contact your physician. Remember, in almost all cases, fever is not the illness; it is the body’s response to fight the illness and regain health.
- Hydrate. When having a fever, we perspire and need more fluids. Thus, increase fluid intake. Almost all cultural traditions recommend drinking some fluids such as hot water with lemon juice and honey, chicken soup broth, etc.
- Reframe the experience as a healing experience versus an illness experience. For example, when a fever, reframe it possitively such as, I feel pleased that my body is responding and I trust that my body is fighting the illness well (or even better).
- Implement the following gentle self-care approaches (Schirm, 2018).
Lemon wrap around calves or feet may help reduce fevers by using the cooling properties of lemon and evaporating water. How to make lemon wraps:
• Fill a bowl with water that’s 2–3° C below your fever temperature.
• Add 1–2 lemon halves.
• Score the lemon peel with a knife to release essential oils.
• Mash the lemons in the water.
• Soak a cloth in the lemon water.
• Wrap the cloth around your calves from ankle to knee.
• Cover with a blanket and rest for 10–15 minutes.
• Repeat as needed.
“Tips for using lemon wraps
• Change the wraps when they become warm.
• If your feet get cold, stop using the wraps.
• Don’t over-bundle a child with blankets, as babies can’t regulate their body temperatures as well as adults.

Ready to crush your New Year’s resolutions and actually stick to them this time? Whether you’re determined to quit vaping or smoking, cut back on sugar and processed foods, reduce screen time, get moving, volunteer more, or land that dream job, sticking to your goals is the real challenge. We’ve all been there: kicking off the year with ambitious plans like, “I’ll work out every day,” or “I’m done with junk food for good.” But a few weeks in? The gym is a distant memory, the junk food stash is back, and those cigarettes are harder to let go of than expected.
So, how can you make this year different? Here are some tried-and-true tips to help you turn those resolutions into lasting habits:
Be clear of your goal and state exactly what you want to do (Pilcher et al., 2022; Latham & Locke, 2006).
Did you know your brain is super literal and doesn’t process “not” the way you think it does? For example, if you say, “I will not smoke,” your brain has to first imagine you smoking, then mentally cross it out. Guess what? By rehearsing the act of smoking in your mind, you’re actually increasing the chances that you’ll light up again.
Think of it like this: hand a four-year-old a cup of hot chocolate and ask them to walk it over to someone across the room. Halfway there, you call out, “Be careful, don’t spill it!” What usually happens? Yep, the hot chocolate spills. That’s because the brain focuses on “spill,” not the “don’t.” Now, imagine instead you say, “You’re doing great! Keep walking steadily.” Positive framing reinforces the action you want to see. The lesson is to reframe your goals in a way that focuses on what you want to achieve, not what you’re trying to avoid. Let’s look at some examples to get you started:
| Negative framing | Positive framing |
| I plan to stop smoking | I choose to become a nonsmoker |
| I will eat less sugar and ultra-processed foods | I will shop at the farmer’s market, buy more fresh vegetable and prepare my own food. |
| I will reduce my negative thinking (e.g., the glass is half empty). | I will describe events and thoughts positively (e.g., the class is half full). |
Describe what you want to do positively.
Be precise and concrete.
The more specific you can describe what you plan to do, the more likely will it occur as illustrated in the following examples.
| Imprecise | Concrete and specific |
| I will begin exercising. | I will buy the gym membership next week Monday and will go to the gym on Monday, Wednesday and Friday right after work at 5:30pm for 45 minutes. |
| I will reduce my angry outbursts, | Before I respond, I will take a slow breath, look up, relax my shoulders and remind myself that the other person is doing their best. |
| I want to limit watching streaming videos | At home, I will move the couch so that it does not face the large TV screen, and I have enrolled in a class to learn another language and I will spent 30 minutes in the evening practicing the new language. |
| I will stop smoking | When I feel the initial urge to smoke, I stand up, do a few stretches, and practice box breathing and remind myself that I am a nonsmoker. |
Describe in detail what you will do.
Identify the benefits of the old behavior that you want to change and how you can achieve the same benefits with your new behavior. (Peper et al, 2002)
When setting a New Year’s resolution, it’s easy to focus on the perks of the new behavior and the harms of the old behavior while overlooking the benefits your old habit provided. However, if you don’t plan ways to achieve the same benefits, the old behavior provided, it’s much harder to stick to your goal.
Before diving into your new resolution, take a moment to reflect. What did your old behavior do for you? What needs did it meet? Once you identify those, you can develop strategies to achieve the same benefits in healthier, more constructive ways.
For example, let’s say your goal is to stop smoking. Smoking might have helped you relax during stressful moments or provided a social activity with friends. To make the switch, you’ll need to find alternatives that deliver similar results, like practicing deep-breathing exercises to manage stress or inviting friends for a walk instead of a smoke break. By creating a plan to meet those needs, you’ll set yourself up for lasting success.
| Benefits of smoking | How to achieve the same benefits when being a none smoker |
| Stress reduction | I will learn relaxation and diaphragmatic breathing. The moment, I feel the urge to smoke, I sit up, look up, raise my shoulder and dropped them, and breathe slowly |
| Breaks during work | I will install a reminder on my cellphone to ping and each time it pings, I stop, stand up, walk around and stretch. |
| Meeting with friends | I will tell my friends, not to offer me a cigarette and I will spent time with friends who are non-smokers. |
| Rebelling against my parents who were opposed to smoking | I will explore how to be independent without smoking |
Describe your benefits and how you will achieve them.
Reduce the cues that evoke the old behavior and create new cues that will trigger the new behavior (Peper & Wilson, 2021).
A lot of our behavior is automatic—shaped by classical conditioning, just like Pavlov’s dog. Remember the famous experiment? Pavlov paired the sound of a bell with food, and after a while, the bell alone made the dog salivate (McLeod, 2024). We’re not so different.
Think about it: if you’ve gotten into the habit of smoking in your car, simply sitting in the driver’s seat can trigger the automatic urge to grab a cigarette. Or, if you tend to feel depressed when you’re home but better when you’re out with friends, your home environment might be acting as a cue for those feelings.
Interestingly, many people find it easier to change habits in a new environment. Why? Because there are no built-in triggers to reinforce the behavior they’re trying to change. This highlights how much of what we often call “addiction” might actually be conditioned behavior, reinforced by familiar cues in our surroundings. By recognizing the power of these triggers can help you disrupt old patterns. By creating a fresh environment or consciously changing your responses to cues, you can take control and start forming new, healthier habits.
This concept has been understood for centuries by some hunting and gathering societies. When something tragic happened—like the death of a family member in a hut—the community would often burn the hut to “eliminate the evil spirit.” Beyond the spiritual aspect, this practice served a practical purpose: it removed all the physical cues that reminded people of their loss, making it easier to focus on the present and move forward.
Of course, I’m not suggesting you destroy your home. But the underlying principle still holds true in modern times. In fact, many Northern European cultures incorporate a version of this idea through the ritual of Spring Cleaning. By decluttering, rearranging furniture, and refreshing the home, the old cues are removed and create a sense of renewal.
So often we forget that cues in our environment play a powerful role in triggering our behavior. By identifying the triggers that evoke old habits and finding ways to remove or change them, you can create a fresh environment that supports your goals. For example, if you’re trying to stop snacking on junk food late at night, consider rearranging your pantry so the tempting items are out of sight—or better yet, replace them with healthier options. Small changes like this can have a big impact on your ability to stay on track.
| Cues that triggered the behavior | How cues were changed |
| In the evening going to the kitchen and getting the chocolate from the cupboard. | Buying fruits and have them on the table and not buying chocolate. If I do buy chocolate store it on the top shelf away so that I do not see it or store it in the freezer. |
| Getting home and being depressed. | Clean the house, change the furniture around and put positive picture high up on the wall. |
| Smoking in the car. | Replace the car with another car that no one had smoked in and spray the care with pine scent. |
Identify the cues that trigger your behavior and how you changed them.
Identify the first sensation that triggered the behavior you would like to change.
Whether it’s smoking, drinking, scratching your skin, spiraling into negative thoughts, or eating too many pastries, once a behavior starts, it can feel nearly impossible to stop. That’s why the key is to catch yourself before the habit takes over., t’s much easier to interrupt a pattern at the very first sign—the initial trigger—rather than after you’ve fully dived into the behavior. Yet how often do we find ourselves saying, “Next time, I’ll do it differently”?
Here’s the strategy: identify the first trigger. This could be a physical sensation, an emotion, a thought, or an external cue. Once you’re aware of that first flicker of a trigger, redirect your thoughts and actions toward what you actually want, rather than letting the automatic behavior take control. For example:
I just came home at 10:15 PM and felt lonely and slightly depressed. I walked into the kitchen, opened the fridge, grabbed a beer, and drank it. Then, I reached for another bottle.
Observing this behavior, the first trigger was the loneliness and slight depression upon arriving home. Recognizing that feeling in the moment offers an opportunity to pause and make a conscious choice. Instead of heading to the fridge, you could redirect your actions—call a friend, go for a quick walk, or write down your thoughts in a journal. By catching that initial trigger, you can focus yourself toward healthier behaviors and break the cycle.
| First sensation | Changed response to the sensation |
| I observed that the first sensation was feeling tired and lonely. | When I entered the house, instead of going to the kitchen, I stretched, looked up and took a deep breath and then called a close friend of mine. We talked for ten minutes and then I went to bed. |
Identify your first sensation and how you changed your behavior.
Incorporate social support and social accountability (Drageset, 2021).
Doing something on your own often requires a lot of willpower, and sticking to it every time can feel like an uphill battle. Take this example:
My goal is to exercise every other morning. But last night, I stayed up late and felt tired in the morning, so I skipped my workout.
Sound familiar? Now imagine if I’d planned to meet a workout buddy. Knowing someone was counting on me would’ve gotten me out of bed, even if I was tired, because I wouldn’t want to let them down.
Accountability can make all the difference. Another powerful strategy is sharing your goals publicly. When you announce your plans on social media or to friends and family, you create a sense of commitment—not just to yourself but to others. It’s like having a built-in support system cheering you on and holding you accountable. Whether it’s finding a partner, joining a group, or sharing your progress online, involving others can help turn your resolutions into habits you’re more likely to stick with.
Describe a strategy to increase social support and accountability.
Be honest in identifying what motivates you.
Exercising, eating healthy foods, thinking positively, or being on time are laudable goals; however, it often feels like work doing the “right” thing. To increase success, analyze what really helped you be successful. For example:
Many years ago, I decided that I should exercise more. Thus, I drove from house to the track and ran eight laps. I did this for the next three weeks and then stopped exercising. Eventually, I pushed myself again to exercise and after a while stopped again. The same pattern kept repeating. I would exercise and fall off the wagon and stop. Later that fall, I met a woman who was a jogger and we became friends and for the next year we jogged together and even did races. During this time, I did not experience any effort to go jogging. After a year, she broke up with me and once again, I had to use willpower to go jogging and my old pattern emerged and after a few days I stopped jogging even though I felt much better after having jogged.
I finally, asked what is going on? I realized that the joy of the jogging was running with a friend. Once, I recognized this, instead using will power to go running, I spent my willpower finding people with whom I could exercise. With these new friends, running did not depend upon my willpower– It only depended on making running dates with my new friends.
Explore factors that will allow you to do your activity without having to use willpower.
Conclusion
These seven strategies are just a starting point—there are countless other techniques that can help you stick to your New Year’s resolutions. For example, keeping a log, setting reminders, or rewarding yourself for progress are all powerful ways to stay on track. The real magic happens when your new behavior becomes part of your routine—embedded in your habitual patterns. The more automatic it feels, the greater your chances of long-term success.
So, take joy in identifying, implementing, and maintaining your resolutions. Let them enhance your well-being and become second nature. Share your successful strategies with me and others—it could be just the inspiration someone else needs to achieve their goals, too.
