Exploring Safe Short-Term Fasting Strategies
I’m a 19-year-old male, standing at 6’4” and weighing around 235 pounds. I'm eager to push my fasting limits beyond what I've previously experienced. After successfully completing a 72-hour fast, I felt fantastic afterward. Throughout that period, I made sure to hydrate adequately with water and zero-calorie sodas—though I’m aware the latter’s compatibility with fasting is somewhat controversial, I decided to include them anyway. Now, I’m contemplating whether I could extend my fast to either 96 hours (four days) or even 120 hours (five days). I’m particularly curious about whether I'd need to start incorporating supplements, specifically electrolytes, during these longer durations. I generally undertake a long fast each month, and I'm keen to gather insights and advice as I prepare for my upcoming fast in April! Thank you in advance for any guidance you can offer!

It's great to hear that you've successfully completed a 72-hour fast and are eager to explore longer fasting durations! While extended fasting can have benefits for some individuals, there are important considerations to ensure it remains safe and effective for your health.
Key Points:
- Hydration and Electrolyte Balance: Prolonged fasting increases the risk of electrolyte imbalances, which can lead to symptoms like fatigue, muscle cramps, or dizziness.
- Safety Considerations: Extending your fast beyond 72 hours requires careful monitoring of your body’s response, especially as you approach the 96- to 120-hour mark.
Explanation:
While many people report feeling good after fasting, it's crucial to listen to your body. The benefits of fasting can be accompanied by potential side effects, especially when done for longer periods. Staying hydrated is crucial, and considering the electrolytes—such as sodium, potassium, and magnesium—may help you maintain energy levels and avoid the physiological stress that can accompany long fasting durations.
Next Steps:
-
Incorporate Electrolytes: For fasts longer than 72 hours, start incorporating electrolyte supplements or consider adding a pinch of sea salt to your water to help maintain electrolyte balance. There are also zero-calorie electrolyte powders available that can be beneficial.
-
Monitor Your Body’s Signals: Pay special attention to how you feel during the fast. If you experience dizziness, excessive fatigue, or any concerning symptoms, it may be wise to break the fast sooner than planned.
-
Stay Hydrated: Continue drinking plenty of water throughout your fasting period. Aim for at least 2-3 liters of water per day, adjusting as necessary based on thirst and activity level.
-
Plan a Gentle Refeed: After your fast, plan for a gentle refeeding phase. Start with small amounts of easily digestible foods to help your digestive system transition back to regular eating.
If you approach your fasting goals with caution and proper self-care, you can make the most of your experience while minimizing potential risks. Enjoy your upcoming fast in April, and be sure to listen to your body throughout the process!

Understanding Patchy Discoloration After Sunburns
I’m a 27-year-old female who has been diagnosed with PCOS and struggles with a vitamin D shortfall. In hindsight, I discovered an occurrence while reviewing some older pictures from a few years back. I’ve noticed that after experiencing sunburns, I occasionally develop these unusual white patches on my skin. It’s quite puzzling since this has only surfaced a handful of times. I typically make it a point to avoid sunburn, so I'm not often in this situation, but it’s interesting to observe that not many others seem to have similar reactions to sunlight exposure. On the day I get sunburned, my skin typically presents a standard pink to red hue. However, when I wake up the next day, I find the color has transformed to this patchy appearance. I’m left wondering if this phenomenon is a typical aspect of skin healing or could it be related to the sunscreen products I apply?
Is a Burning Sensation from Mouthwash Common?
I've recently been using a mint-flavored mouthwash, specifically Crest's teeth whitening formula. However, it caused significant discomfort, stinging my lips and tongue to the point where I felt compelled to switch to Therabreath. Additionally, I had come across information suggesting that teeth whitening mouthwashes might harm your enamel. Therabreath also contains fluoride and mint, and while it still causes some burning, it's noticeably more tolerable than the previous brand. For a long time, I assumed this burning sensation was simply a normal part of using mouthwash, as I have experienced similar discomfort during dental visits throughout my life. To manage the sting from Therabreath, I've found that spitting it out before the pain becomes too intense has been a helpful strategy since it's not quite as severe. At this point, I am uncertain if my reaction is specific to mint or another ingredient present in the mouthwash. I have always disliked using mouthwash due to the discomfort it brings, but Therabreath is just tolerable enough that I keep using it. I'm turning to Reddit for advice first, as I would prefer not to visit my doctor only to be told that this sensation is typical and thus wasting her time. Being autistic, I sometimes find certain sensory experiences overwhelming, and it’s possible that I could just be particularly sensitive in this case.
Experiencing Unexpected Breathlessness One Month After Gallbladder Surgery – Should I Worry?
A 26-year-old woman, weighing 44 kilograms and standing at 5 feet 4 inches, does not smoke or drink. A month has passed since I underwent laparoscopic gallbladder removal, and while my recovery has generally been smooth, I've faced some bouts of fatigue. However, today I encountered something alarming: I felt a sudden shortness of breath after ascending a flight of stairs, which struck me as unusual. Later, while trying on outfits for an upcoming event, the same thing happened again—I became breathless. After some online research, I stumbled upon information regarding pulmonary embolism, which left me feeling quite frightened. Could this be a serious issue? Should I consider consulting my surgeon for further advice?
Experiencing Intense Night Sweats?
I’m a 22-year-old female, weighing 120 pounds and standing at 5’4”. I've had a history of post-viral illness, polycystic ovary syndrome (PCOS), and major depressive disorder (MDD). Throughout my life, I've dealt with intermittent night sweats, but it has escalated recently—in the last month or two, I've been experiencing them nightly. I've tried switching out my bedding, adjusting the temperature in my bedroom, and a few other strategies, yet I still wake up drenched, as if I’ve been sprayed with water. My clothes are soaked, my hair feels greasy and wet, and it leaves me feeling quite uncomfortable. To avoid ruining yet another pair of pajamas, I often opt to sleep without any clothes for the remainder of the night. Because of my other health issues, I undergo blood tests fairly frequently—about three to four times a year—and my physician hasn’t indicated any alarming results besides addressing those tests specifically. What could be causing this? It’s incredibly frustrating to wake up at 3 a.m. every night feeling like this.
Struggles with Sleep Due to Flu/COVID
Caution: This message may not be well-articulated as I am running on little to no sleep. I’m an 18-year-old male, currently weighing around 175 pounds, down from 185 before falling ill. For the past four days, I have been dealing with what I suspect is either the flu or COVID-19. I’ve been taking aspirin, ibuprofen, and both daytime and nighttime cold and flu medications. Generally, these have worked for me, save for one incident where I vomited the flu medicine shortly after taking it. Fortunately, I managed to have my lunch, a small bowl of honey yogurt, without issues. My main symptoms include heavy congestion, a sore throat, persistent headaches, and overwhelming fatigue. However, I face a significant challenge: I cannot fall asleep at night. Yesterday, I tried staying awake throughout the day, believing it might help me rest at night, but I ended up unable to sleep then as well. I feel utterly drained, and even simple activities like walking are a struggle. Yet, when I try to rest, sleep eludes me completely.
