Convincing yourself to workout especially during winter season is a testament to your dedication towards fitness. While you may be competing with the urge to stay in the comfort of your sheets and the need to keep a consistent routine of working out, many people look for a middle ground and opt to work out indoors. Just because the temperature drops doesn't mean you have to confine your workouts indoors. Exercising outdoors in cooler weather can be both enjoyable and beneficial, provided you take the necessary precautions.

Why Exercising In Winters Is Better

Even when temperatures dip into the 30s and 40s, activities like walking, running, and cycling can still be enjoyed outdoors. In fact, colder weather can have surprising advantages and many people don’t even venture outside to find out about them. According to Harvard Health Publishing, we learned that lower temperatures can improve endurance because your heart doesn't have to work as hard, you sweat less, and expend less energy, leading to more efficient workouts. Studies also suggest that cold-weather exercise can help you convert white fat like the ones found in the belly and thigh fat into calorie-burning brown fat. Additionally, exposure to sunlight during winter workouts can help combat seasonal affective disorder (SAD). However, people who have certain health conditions like asthma or heart problems should consult their doctor before engaging in cold-weather exercise and follow the advice given to them without fail.

How Should One Prevent Hypothermia and Injuries?

However, exercising in cold weather increases the risk of hypothermia which means that your body gets an abnormally low body temperature. If you start experiencing intense shivering, extreme fatigue, slurred speech, or loss of coordination, you need to seek immediate medical attention. Always inform someone of your outdoor plans and carry a fully charged phone, if you are absent for too long, your guardian can reach you and in case you do not pick up, they can keep a note of it and find help. Cold muscles are also more susceptible to strains and injuries, making a proper warm-up essential, people try to avoid it to cut time, but you are just putting yourself up for harm. Avoid static stretches before exercise; instead, opt for dynamic stretches that involve movement to loosen joints, increase blood flow, and warm up muscles. for example, you can try arm circles, arm swings, high steps, and lunges.

Tips To Stay Safe During Winter Workouts

Layering for Warmth and Comfort

Dressing in layers is very important when it comes to regulating body temperature. Start with a moisture-wicking base layer, then add an insulating layer like fleece or wool, and finish with a waterproof, breathable outer layer. Avoid cotton, as it retains sweat and can make you colder.

Protecting Extremities

Protecting your head, hands, and feet is vital, as blood flow is concentrated in the core. These are sensitive areas that can carry cold to your core. Always wear warm gloves, preferably lined with wool or fleece, and thick, warm socks. Wear a hat or beanie to prevent heat loss from your head and protect your eyes with sunglasses.

Sun Protection and Hydration

Even in winter, sun protection and hydration are essential many people believe that you only need it to avoid tanning, but that is not the case. Apply sunscreen with an SPF of 30 or higher, even on cloudy days, and use lip balm with SPF. Drink water before, during, and after your workout, as cold air can suppress thirst.

Choosing Safe Routes and Footwear

Choosing safe routes and wearing appropriate footwear can prevent slips and falls if you see that your usual route has water or some icy layers, avoid it.. Choose routes with good footing and clear pathways. Wear shoes or boots with good traction and consider using walking poles for added stability on potentially slippery surfaces.

Prioritizing Safety

Always listen to your body and prioritize safety during cold-weather exercise, while the mindset of pushing your body past its limits is understandable, during winter season you need to be more aware. If you feel too cold, lightheaded, or experience any discomfort, stop your workout and warm up immediately. Safety should always be the primary concern during outdoor activities.

We have always been told that truly sustainable weight loss is a long-term process made up of daily physical activity, healthy eating, and regular sleep. However, a four-minute workout from Japan, which has taken social media by storm, has confidently challenged this idea.

Making an ambitious promise, the makers of the workout claim that one can lose around 5 kg in just one week with the 4-minute workout.

The video, which was reshared on social media, has crossed 3 million views on X, with nearly 60,000 likes, has sparked a debate whether the short routine could really replace a longer gym session.

The virality of the video makes sense. Most of us argue with ourselves everyday, trying to talk ourselves out of going to the gym and spending hours toiling away. But do we realistically need just a few minutes to get in shape?

You don't need dumbbells, gym membership, or any special equipment to do this workout routine. You can apparently do it almost anywhere.

There is no evidence that four minutes of exercise a day can make someone lose 5 kg of body weight in seven days. The viral claim comes from the makers of the video, rather than a clinical study showing that people following the routine lost 5 kg in a week.

Experts also say that such a drastic amount of weight loss in seven days is not realistically achievable for most people.

Additionally, what appears on the weighing scale can also move up or down because of water retention, food in the digestive system, and other short-term changes. A sudden drop in weight therefore does not necessarily mean that 5 kg of body fat has disappeared.

Losing considerable body fat needs more than just a 'very short workout'. Along with at least 30 minutes of physical activity, one needs a sustained calorie deficit.

The Four Minutes Of Exercise Is Not Completely Useless

Now as the facts are clear, we would be remiss to not appreciate the routine's biggest potential, which is getting inactive people to move, not weight loss.

Four minutes of activity is certainly better than spending those four minutes sitting still. If a short routine like this Japanese workout feels manageable enough to turn it into a daily habit, it can give you a starting point for physical activity, which you can gradually increase.

But one needs to be careful. A short workout routine usually makes your heart work harder. If you experience pain, dizziness, chest discomfort, or an irregular heartbeat, you must stop immediately.

People who are new to exercise or have existing health concerns should speak with a doctor before starting a new routine.

How To Lose Weight Safely?

Rather than trying to take a shortcut and achieve a drastic weight loss in less days, opt for a more sustainable approach is to gradually increase daily movement and combine it with a balanced diet.

Novak Djokovic, the 24-time Grand Slam champion, suffered his earliest Grand Slam exit in 20 years after crashing out in the first round of the US Open with a five-set defeat to Argentina’s Mariano Navone.

Djokovic was left in tears after bouts of vomiting, cramping and pain. He also relied on multiple medical timeouts, an inhaler and pills to stay on the court.

“I despised every moment I was on the court,” Djokovic told the media after the match, adding that he had been dealing with similar issues throughout the season.

“I think it was obvious that it was an awful feeling on the court for me. It’s something that I’ve been carrying, unfortunately, pretty much every match this year,” he said.

Djokovic described how his body broke down during the match.

“Vomiting, throwing up, a serious issue there. Then my whole body starts to collapse, basically cramping and pain. The back just gave up in the end and my shoulder, and I couldn’t close it out,” he added.

The defeat ended Djokovic’s hopes of winning a 25th Grand Slam title at this year’s US Open.

Similar Struggles In Cincinnati

Earlier this month at the Cincinnati Open, Djokovic, who holds the all-time men’s record of 428 weeks as world No. 1 in singles, also struggled physically throughout his second-round match.

The 39-year-old was seen crouching on all fours between points, required a medical timeout and appeared to vomit into towels as extreme heat and humidity took a toll.

He then suffered a surprising second-round defeat, losing to Argentina’s Thiago Agustín Tirante 2-6, 6-4, 6-4.

Following the defeat, Djokovic revealed that he had been dealing with a longstanding health condition that becomes particularly difficult to manage in hot and humid conditions.

“It’s because of a health issue I have,” Djokovic told reporters after the match. “I’ve been dealing with it for many years now. It causes me a lot of problems, especially when there’s a lot of humidity and heat.”

Djokovic is not alone in facing physical challenges. His exit comes after world No. 1 Jannik Sinner withdrew from the tournament due to injury, while defending champion Carlos Alcaraz entered the event after a long break.

Other names include Italy’s Lorenzo Musetti and France’s Arthur Fils who missed earlier Grand Slams in 2026 with injuries, and No. 2 seed Elena Rybakina managing a heel injury ahead of her opener.

Together, these developments raise a broader question: Are the demands of elite tennis becoming too much for even the world’s best players?

While Djokovic has not revealed the nature of his illness, he told reporters that he is “trying” to address the ailment.

Age, Recovery And The Demands Of Tennis

In 2023, Djokovic acknowledged that his body was beginning to feel the effects of a long career, although he still felt he had fuel left in the tank.

“The desire is still there, but things can change quickly – I am 36, I’ve been a pro for 20 years.”

He said he did not view age as a decisive factor, instead focusing on his overall physical condition and whether he continued to enjoy playing.

Age can affect tennis performance through changes such as reduced muscle mass, slower recovery and lower aerobic capacity, which can also increase injury risk.

Year-round Tours, Extreme Heat

In addition to performance pressures, the grueling schedules of the ATP and WTA Tours that span nearly 11 months of the year, give athletes limited time to rest and recover from injuries.

At the same time, rising global temperatures and intense matches lasting up to five hours have added further physical challenges.

“We’re losing the battle overall despite the advances in sports medicine,” Neeru Jayanthi, who leads the tennis medicine programme at Emory Healthcare in Atlanta, told The Straits Times.

Along with creating new avenues for managing type 2 diabetes and metabolic health, GLP-1 drugs like Ozempic, Wegovy, Mounjaro, and Zepbound are also transforming the weight loss game.

Despite its striking benefits in tackling obesity, it poses the risk of significant muscle loss as it works by reducing appetite rather than burning energy.

To address this issue, researchers at the University of California, Berkeley have identified an experimental compound. It could offer a very different approach to weight loss that may not result in excessive muscle loss.

How Was The Study Conducted?

The compound, called 5-tetradecyloxy-2-furoic acid, or TOFA, is not approved as a weight-loss treatment and has so far only been tested in animals. Weight loss is the result of mainly two bodily mechanisms: Taking in fewer calories than the amount burned during a specific period.

Since GLP-1 drugs only focus on the first part, the resultant weight loss also includes loss of lean muscle mass. TOFA is developed to increase the amount of energy burned rather than just supressing appetite.

Anders Näär, professor of metabolic biology and nutrition at UC Berkeley and senior author of the study, explained, "Body weight responds to two levers: taking in fewer calories or spending more energy. GLP-1s work almost entirely on the first, so we went after the second."

When tested on mice, it increased energy use by as much as 18% without making the animals more physically active or raising their body temperature. The mice lost body fat without a significant reduction in lean muscle mass.

How Does TOFA Compound Work?

TOFA belongs to a group of compounds known as ACC inhibitors. It interferes with the production of lipids like cholesterol and triglycerides while also activating cells involved in utilising fat as fuel.

Researchers found that TOFA activated PPARα and PPARδ, receptors that switch on genes involved in fat uptake and energy expenditure. Justin Y. Lee, the study's first author, said, “TOFA appears to engage a coordinated metabolic response.”

He added, “It is not simply blocking lipid synthesis. It is also activating energy expenditure pathways that may help the body handle excess lipid and glucose more effectively.”

The mice also showed improvements in insulin sensitivity, blood glucose, triglycerides, and signs of fatty liver disease.

Could TOFA Be Combined With Ozempic Or Mounjaro?

The researchers tested TOFA alongside GLP-1 drugs including semaglutide and tirzepatide. In mice, the combinations produced greater improvements in body weight, glucose control, insulin levels, and triglycerides than either treatment alone.

Näär said, “TOFA worked additively or synergistically with the GLP-1 appetite-suppressing drugs, so we view it as complementary rather than as a replacement.”

In other words, researchers are looking to maximise the benefits of the two-pronged approach: One drug could dial your appetite down while another could turn up energy expenditure.

Despite promising results, we have to take a pause as TOFA is not yet an approved human weight-loss drug, meaning researchers do not yet know whether the compound will produce the same effects, or whether it will be safe, in humans.
