You’ve had a cold or the flu and your symptoms have begun to subside. Your nose has stopped dripping, your cough is clearing and your head and muscles no longer ache.

You’re ready to get off the couch. But is it too early to go for a run? Here’s what to consider when getting back to exercising after illness.

Exercise can boost your immune system – but not always

Exercise reduces the chance of getting respiratory infections by increasing your immune function and the ability to fight off viruses.

However, an acute bout of endurance exercise may temporarily increase your susceptibility to upper respiratory infections, such as colds and the flu, via the short-term suppression of your immune system. This is known as the “open window” theory.

A study from 2010 examined changes in trained cyclists’ immune systems up to eight hours after two-hour high-intensity cycling. It found important immune functions were suppressed, resulting in an increased rate of upper respiratory infections after the intense endurance exercise.

So, we have to be more careful after performing harder exercises than normal.

Can you exercise when you’re sick?

This depends on the severity of your symptoms and the intensity of exercise.

Mild to moderate exercise (reducing the intensity and length of workout) may be OK if your symptoms are a runny nose, nasal congestion, sneezing and minor sore throat, without a fever.

Exercise may help you feel better by opening your nasal passages and temporarily relieving nasal congestion.

However, if you try to exercise at your normal intensity when you are sick, you risk injury or more serious illness. So it’s important to listen to your body.

If your symptoms include chest congestion, a cough, upset stomach, fever, fatigue or widespread muscle aches, avoid exercising. Exercising when you have these symptoms may worsen the symptoms and prolong the recovery time.

If you’ve had the flu or another respiratory illness that caused a high fever, make sure your temperature is back to normal before getting back to exercise. Exercising raises your body temperature, so if you already have a fever, your temperature will become high quicker, which makes you sicker.

If you have COVID or other contagious illnesses, stay at home, rest and isolate yourself from others.

When you’re sick and feel weak, don’t force yourself to exercise. Focus instead on getting plenty of rest. This may actually shorten the time it takes to recover and resume your normal workout routine.

I’ve been sick for a few weeks. What has happened to my strength and fitness?

You may think taking two weeks off from training is disastrous, and worry you’ll lose the gains you’ve made in your previous workouts. But it could be just what the body needs.

It’s true that almost all training benefits are reversible to some degree. This means the physical fitness that you have built up over time can be lost without regular exercise.

To study the effects of de-training on our body functions, researchers have undertaken “bed rest” studies, where healthy volunteers spend up to 70 days in bed. They found that V̇O₂max (the maximum amount of oxygen a person can use during maximal exercise, which is a measure of aerobic fitness) declines 0.3–0.4% a day. And the higher pre-bed-rest V̇O₂max levels, the larger the declines.

In terms of skeletal muscles, upper thigh muscles become smaller by 2% after five days of bed rest, 5% at 14 days, and 12% at 35 days of bed rest.

Muscle strength declines more than muscle mass: knee extensor muscle strength gets weaker by 8% at five days, 12% at 14 days and more than 20% after around 35 days of bed rest.

This is why it feels harder to do the same exercises after resting for even five days.

But in bed rest studies, physical activities are strictly limited, and even standing up from a bed is prohibited during the whole length of a study. When we’re sick in bed, we have some physical activities such as sitting on a bed, standing up and walking to the toilet. These activities could reduce the rate of decreases in our physical functions compared with study participants.

How to ease back into exercise

Start with a lower-intensity workout initially, such as going for a walk instead of a run. Your first workout back should be light so you don’t get out of breath. Go low (intensity) and go slow.

Gradually increase the volume and intensity to the previous level. It may take the same number of days or weeks you rested to get back to where you were. If you were absent from an exercise routine for two weeks, for example, it may require two weeks for your fitness to return to the same level.

If you feel exhausted after exercising, take an extra day off before working out again. A day or two off from exercising shouldn’t affect your performance very much.

  • Amid Wildfire Trauma, L.A. County Dispatches Mental Health Workers to Evacuees

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    PASADENA, Calif. — As Fernando Ramirez drove to work the day after the Eaton Fire erupted, smoke darkened the sky, ash and embers rained onto his windshield, and the air smelled of melting rubber and plastic.

    He pulled to the side of the road and cried at the sight of residents trying to save their homes.

    “I could see people standing on the roof, watering it, trying to protect it from the fire, and they just looked so hopeless,” said Ramirez, a community outreach worker with the Pasadena Public Health Department.

    That evening, the 49-year-old volunteered for a 14-hour shift at the city’s evacuation center, as did colleagues who had also been activated for emergency medical duty. Running on adrenaline and little sleep after finding shelter for homeless people all day, Ramirez spent the night circulating among more than a thousand evacuees, offering wellness checks, companionship, and hope to those who looked distressed.

    Local health departments, such as Ramirez’s, have become a key part of governments’ response to wildfires, floods, and other extreme weather events, which scientists say are becoming more intense and frequent due to climate change. The emotional toll of fleeing and possibly losing a home can help cause or exacerbate mental health conditions such as anxiety, depression, post-traumatic stress disorder, suicidal ideation, and substance use, according to health and climate experts.

    Wildfires have become a recurring experience for many Angelenos, making it difficult for people to feel safe in their home or able to go about daily living, said Lisa Wong, director of the Los Angeles County Department of Mental Health. However, with each extreme weather event, the county has improved its support for evacuees, she said.

    For instance, Wong said the county deployed a team of mental health workers trained to comfort evacuees without retraumatizing them, including by avoiding asking questions likely to bring up painful memories. The department has also learned to better track people’s health needs and redirect those who may find massive evacuation settings uncomfortable to other shelters or interim housing, Wong said. In those first days, the biggest goal is often to reduce people’s anxiety by providing them with information.

    “We’ve learned that right when a crisis happens, people don’t necessarily want to talk about mental health,” said Wong, who staffed the evacuation site Jan. 8 with nine colleagues.

    Instead, she and her team deliver a message of support: “This is really bad right now, but you’re not going to do this alone. We have a whole system set up for recovery too. Once you get past the initial shock of what happened — initial housing needs, medication needs, all those things — then there’s this whole pathway to recovery that we set up.”

    The convention center in downtown Pasadena, which normally hosts home shows, comic cons, and trade shows, was transformed into an evacuation site with hundreds of cots. It was one of at least 13 shelters opened to serve more than 200,000 residents under evacuation orders.

    The January wildfires have burned an estimated 64 square miles — an area larger than the city of Paris — and destroyed at least 12,300 buildings since they started Jan. 7. AccuWeather estimates the region will likely face more than $250 billion in economic losses from the blazes, surpassing the estimates from the state’s record-breaking 2020 wildfire season.

    Lisa Patel, executive director of the Medical Society Consortium on Climate and Health, said she’s most concerned about low-income residents, who are less likely to access mental health support.

    “There was a mental health crisis even before the pandemic,” said Patel, who is also a clinical associate professor of pediatrics at Stanford School of Medicine, referring to the covid-19 pandemic. “The pandemic made it worse. Now you lace in all of this climate change and these disasters into a health care system that isn’t set up to care for the people that already have mental health illness.”

    Early research suggests exposure to large amounts of wildfire smoke can damage the brain and increase the risk of developing anxiety, she added.

    At the Pasadena Convention Center, Elaine Santiago sat on a cot in a hallway as volunteers pulled wagons loaded with soup, sandwiches, bottled water, and other necessities.

    Santiago said she drew comfort from being at the Pasadena evacuation center, knowing that she wasn’t alone in the tragedy.

    “It sort of gives me a sense of peace at times,” Santiago said. “Maybe that’s weird. We’re all experiencing this together.”

    She had been celebrating her 78th birthday with family when she fled her home in the small city of Sierra Madre, east of Pasadena. As she watched flames whip around her neighborhood, she, along with children and grandkids, scrambled to secure their dogs in crates and grabbed important documents before they left.

    The widower had leaned on her husband in past emergencies, and now she felt lost.

    “I did feel helpless,” Santiago said. “I figured I’m the head of the household; I should know what to do. But I didn’t know.”

    Donny McCullough, who sat on a neighboring green cot draped in a Red Cross blanket, had fled his Pasadena home with his family early on the morning of Jan. 8. Without power at home, the 68-year-old stayed up listening for updates on a battery-powered radio. His eyes remained red from smoke irritation hours later.

    “I had my wife and two daughters, and I was trying not to show fear, so I quietly, inside, was like, ‘Oh my God,’” said McCullough, a music producer and writer. “I’m driving away, looking at the house, wondering if it’s going to be the last time I’m going to see it.”

    He saved his master recording from a seven-year music project, but he left behind his studio with all his other work from a four-decade career in music.

    Not all evacuees arrived with family. Some came searching for loved ones. That’s one of the hardest parts of his shift, Ramirez said. The community outreach worker helped walk people around the building, cot by cot.

    A week in, at least two dozen people had been killed in the wildfires.

    The work takes a toll on disaster relief workers too. Ramirez said many feared losing their homes in the fires and some already had. He attends therapy weekly, which he said helps him manage his emotions.

    At the evacuation center, Ramirez described being on autopilot.

    “Some of us react differently. I tend to go into fight mode,” Ramirez said. “I react. I run towards the fire. I run towards personal service. Then once that passes, that’s when my trauma catches up with me.”

    Need help? Los Angeles County residents in need of support can call the county’s mental health helpline at 1-800-854-7771. The national Suicide & Crisis Lifeline, 988, is also available for those who’d like to speak with someone confidentially, free of charge.

    Carb-strong or carb-wrong? We’ve written about this ourselves before, and it comes down to clarifying questions of what and how and why. Even within the general field of carbs, even within the smaller field of starch, not all foods are equal. A slice of white bread and a baked potato are both starchy, but the latter also contains fiber, vitamins, minerals, and suchlike.

    The authors make the case for a whole-foods plant-based diet in which one need not shy away from starchy foods in general; one simply must enjoy them discriminately—whole grains, and root vegetables that have not been processed to Hell and back, for examples.

    The style is “old-school pop-sci” but with modern science; claims are quite well-sourced throughout, with nine pages of bibliography at the end. Right after the ninety-nine pages of recipes!

    Bottom line: if you’re a carb-enjoyer, all is definitely not lost healthwise, and in fact on the contrary, this can be the foundation of a very healthy and nutrient-rich diet.

    We’ve previously reviewed Dr. Spector’s “Food For Life”, and while that was more of an “explanatory science” book, this one takes that science (reiterating it more briefly this time, by way of introduction) and makes a cookbook of it.

    The nutritional emphasis in these recipes is on two things: maximizing fiber, and maximizing plant diversity. The recipes are not all vegan or even vegetarian, but they are plant-centric, and if the reader is vegetarian/vegan, then substitutions are easy to make.

    The recipes themselves are simple without being boring, and are easy to follow, with full-page photos to accompany them. The science parts are very clear, accessible, and pop-science in style.

    Bottom line: if you’d like to incorporate more fiber and more plants into your diet without it being a burden, this book is great for that.

  • Pineapple vs Passion Fruit – Which is Healthier?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Our Verdict

    When comparing pineapple to passion fruit, we picked the passion fruit.

    Why?

    Both are certainly great, and both have won their respective previous comparisons! And this one’s close:

    In terms of macros, passion fruit has about 4x the protein, nearly 2x the carbs, and more than 7x the fiber. So, this one’s a clear and overwhelming win for passion fruit.

    Vitamins are quite close; pineapple has more of vitamins B1, B5, B6, B9, and C, while passion fruit has more of vitamins A, B2, B3, and choline. So, a 5:4 marginal win for pineapple.

    When it comes to minerals, pineapple has more calcium, copper, manganese, and zinc, while passion fruit has more iron, manganese, phosphorus, potassium, and selenium. Superficially, this would be a 5:5 tie, but looking at the numbers, passion fruit’s margins of difference are much greater, which means it gives the better overall mineral coverage, and thus wins the category.

    Looking at polyphenols, pineapple wins this category with its variety of lignans, while passion fruit has just secoisolariciresinol, of which pineapple has more anyway. Plus, not a polyphenol but doing much of the same job of same, pineapple has bromelain, which is unique to it. So pineapple wins on the phytochemicals reckoning.

    Adding up the sections and weighting them for importance (e.g. what a difference it makes to health) and statistical relevance (e.g. greater or smaller margins of difference) makes for a nominal passion fruit win, but like we say, both of these fruits are great, so enjoy both!

  • Why do some young people use Xanax recreationally? What are the risks?

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    Anecdotal reports from some professionals have prompted concerns about young people using prescription benzodiazepines such as Xanax for recreational use.

    Border force detections of these drugs have almost doubled in the past five years, further fuelling the worry.

    So why do young people use them, and how do the harms differ to those used as prescribed by a doctor?

    Dragana Gordic/Shutterstock

    What are benzodiazepines?

    You might know this large group of drugs by their trade names. Valium (diazepam), Xanax (alprazolam), Normison (temazepam) and Rohypnol (flunitrazepam) are just a few examples. Sometimes they’re referred to as minor tranquillisers or, colloquially, as “benzos”.

    They increase the neurotransmitter gamma aminobutyric acid (GABA). GABA reduces activity in the brain, producing feelings of relaxation and sedation.

    Unwanted side effects include drowsiness, dizziness and problems with coordination.

    Benzodiazepines used to be widely prescribed for long-term management of anxiety and insomnia. They are still prescribed for these conditions, but less commonly, and are also sometimes used as part of the treatment for cancer, epilepsy and alcohol withdrawal.

    Long-term use can lead to tolerance: when the effect wears off over time. So you need to use more over time to get the same effect. This can lead to dependence: when your body becomes reliant on the drug. There is a very high risk of dependence with these drugs.

    When you stop taking benzodiazepines, you may experience withdrawal symptoms. For those who are dependent, the withdrawal can be long and difficult, lasting for several months or more.

    So now they are only recommended for a few weeks at most for specific short-term conditions.

    How do people get them? And how does it make them feel?

    Benzodiazepines for non-medical use are typically either diverted from legitimate prescriptions or purchased from illicit drug markets including online.

    Some illegally obtained benzodiazepines look like prescription medicines but are counterfeit pills that may contain fentanyl, nitazenes (both synthetic opioids) or other potent substances which can significantly increase the risk of accidental overdose and death.

    When used recreationally, benzodiazepines are usually taken at higher doses than those typically prescribed, so there are even greater risks.

    The effect young people are looking for in using these drugs is a feeling of profound relaxation, reduced inhibition, euphoria and a feeling of detachment from one’s surroundings. Others use them to enhance social experiences or manage the “comedown” from stimulant drugs like MDMA.

    There are risks associated with using at these levels, including memory loss, impaired judgement, and risky behaviour, like unsafe sex or driving.

    Some people report doing things they would not normally do when affected by high doses of benzodiazepines. There are cases of people committing crimes they can’t remember.

    When taken at higher doses or combined with other depressant drugs such as alcohol or opioids, they can also cause respiratory depression, which prevents your lungs from getting enough oxygen. In extreme cases, it can lead to unconsciousness and even death.

    Using a high dose also increases risk of tolerance and dependence.

    Is recreational use growing?

    The data we have about non-prescribed benzodiazepine use among young people is patchy and difficult to interpret.

    The National Drug Strategy Household Survey 2022–23 estimates around 0.5% of 14 to 17 year olds and and 3% of 18 to 24 year olds have used a benzodiazepine for non medical purposes at least once in the past year.

    The Australian Secondary Schools Survey 2022–23 reports that 11% of secondary school students they surveyed had used benzodiazepines in the past year. However they note this figure may include a sizeable proportion of students who have been prescribed benzodiazepines but have inadvertently reported using them recreationally.

    In both surveys, use has remained fairly stable for the past two decades. So only a small percentage of young people have used benzodiazepines without a prescription and it doesn’t seem to be increasing significantly.

    Reports of more young people using benzodiazepines recreationally might just reflect greater comfort among young people in talking about drugs and drug problems, which is a positive thing.

    Prescribing of benzodiazepines to adolescents or young adults has also declined since 2012.

    What can you do to reduce the risks?

    To reduce the risk of problems, including dependence, benzodiazepines should be used for the shortest duration possible at the lowest effective dose.

    Benzodiazepines should not be taken with other medicines without speaking to a doctor or pharmacist.

    You should not drink alcohol or take illicit drugs at the same time as using benzodiazepines.

    Counterfeit benzodiazepines are increasingly being detected in the community. They are more dangerous than pharmaceutical benzodiazepines because there is no quality control and they may contain unexpected and dangerous substances.

    Drug checking services can help people identify what is in substances they intend to take. It also gives them an opportunity to speak to a health professional before they use. People often discard their drugs after they find out what they contain and speak to someone about drug harms.

    If people are using benzodiazepines without a prescription to self manage stress, anxiety or insomnia, this may indicate a more serious underlying condition. Psychological therapies such as cognitive behaviour therapy, including mindfulness-based approaches, are very effective in addressing these symptoms and are more effective long term solutions.

    Lifestyle modifications – such as improving exercise, diet and sleep – can also be helpful.

    There are also other medications with a much lower risk of dependence that can be used to treat anxiety and insomnia.

    If you or someone you know needs help with benzodiazepine use, Reconnexions can help. It’s a counselling and support service for people who use benzodiazepines.

    Alternatively, CounsellingOnline is a good place to get information and referral for treatment of benzodiazepine dependence. Or speak to your GP. The Sleep Health Foundation has some great resources if you are having trouble with sleep.

  • Here’s how to help protect your family from norovirus

    10almonds is reader-supported. We may, at no cost to you, receive a portion of sales if you purchase a product through a link in this article.

    What you need to know

    • Norovirus is a very contagious infection that causes vomiting and diarrhea.
    • The best way to help protect against norovirus is to wash your hands often with soap and warm water, since hand sanitizer may not be effective at killing the virus.
    • If someone in your household has symptoms of norovirus, isolate them away from others, watch for signs of dehydration, and take steps to help prevent it from spreading.

    If you feel like everyone is sick right now, you’re not alone. Levels of respiratory illnesses like COVID-19, flu, and RSV remain remain high in many states, and the U.S. is also battling a wave of norovirus, one of several viruses that cause a very contagious infection of the stomach and intestines. 

    Although norovirus infections are more common during the colder months—it’s also called the “winter vomiting disease”—the virus can spread at any time. Right now, however, cases have more than doubled since last year’s peak.

    Read on to learn about the symptoms of norovirus, how it spreads, and what to do if someone in your household gets sick.

    What are the symptoms of norovirus?

    Norovirus is a very contagious infection that causes vomiting and diarrhea, which typically begins 12 to 48 hours after exposure to the virus. Additional symptoms may include stomach pain, body aches, headaches, and a fever. Norovirus typically resolves within three days, but people who are infected may still be contagious for up to two days after symptoms resolve.

    Norovirus may cause dehydration, or a dangerous loss of fluids, especially in young children and older adults. See a health care provider if you or someone in your household shows signs of dehydration, which may include decreased urination, dizziness, a dry mouth and throat, sleepiness, and crying without tears.

    How can you help protect against norovirus?

    You can get norovirus if you have close contact with someone who is infected, touch a contaminated surface and then touch your mouth or nose, or consume contaminated food or beverages.

    The best way to help protect yourself and others against norovirus is to wash your hands often with soap and warm water, since hand sanitizer may not be effective at killing the virus. Other ways to help protect yourself may include cooking food thoroughly and washing fruits and vegetables before eating them.

    You can get sick with norovirus even if you’ve had it before, since there are many different strains.

    How can families help protect against the spread of norovirus at home?

    If someone in your household has symptoms of norovirus, isolate them away from others and watch for signs of dehydration. If you are sick with norovirus, do not prepare food for others in your household and use a separate bathroom, if possible.

    When cleaning up after someone who has norovirus, wear rubber, latex, or nitrile gloves. Then wash your hands thoroughly.

    Clean surfaces using a solution containing five to 25 tablespoons of bleach (that’s 12.5 fluid ounces, or just  over ¾ cup), per gallon of water. Leave the bleach-water mix on surfaces for at least five minutes before wiping it off.

    For more information, talk to your health care provider.
