Regular exercise in the winter months takes more planning than the rest of the year. It gets dark early, temperatures drop, rain disrupts the schedule and motivation naturally declines. On top of that come the upper respiratory tract infections that spread during winter; many people consider giving up exercise altogether “to avoid getting sick”.

It is interesting to observe how studio attendance fluctuates around Cevizli and Maltepe in winter: between December and February, some of the participants who run or walk outdoors switch to indoor classes, while others suspend their routine entirely. The aim when planning winter programs at O’Wellness Dragos is precisely to prevent that second outcome: preserving continuity, even if it means changing the intensity.

This article is for general information only and is not medical advice. The effects of exercise on the immune system are still being researched and debated; no guarantee of protection is offered here. If you have a known condition or are experiencing symptoms of illness, consult your physician.

An honest answer to “Does exercise strengthen immunity?”

This subject is often presented in exaggerated terms online. A more measured statement would be: regular, moderate-intensity physical activity is counted among the lifestyle habits that support general health. But exercise is not a shield that prevents illness, and no training program guarantees protection from infection.

So a more realistic framework is to keep exercising through winter not “to avoid getting sick” but for these reasons:

Preserving the conditioning and strength you have gained (regaining it after a break is harder)
Offsetting the clear drop in daily movement during winter
Maintaining routine and social contact, a factor many people report as supporting their mood
Helping prevent your sleep schedule from falling apart
Not having to start from zero in the spring

Why is intensity balance discussed?

A point that often comes up in exercise physiology is that the fatigue period following very high intensity, long duration training can temporarily leave a person more tired and more strained. The findings on this are not settled and continue to be debated.

The practical conclusion is still reasonable: in winter, especially during a period of poor sleep and a heavy workload, distributing intensity evenly across the week is a more sustainable approach than pushing every session to the limit.

Weekly intensity distribution for winter

For someone training three days a week, a sensible distribution could be built like this:

1 day a more intense session (a strength-focused class or circuit)
1 day a moderate-intensity session (reformer pilates, a functional class)
1 day a light, recovery-focused session (flexibility, slow yoga, a brisk walk)

The advantage of this setup is that even in a tiring week at least one class is “easy”. People usually abandon a routine not because workouts are hard, but because every single workout is hard.

What should you do during a period of poor sleep?

If sleep is insufficient, lowering the intensity is generally better than canceling the session altogether. A light 30-minute session instead of an intense 60-minute class preserves the routine without creating excessive fatigue.

Should you train when you are sick?

There are oversimplified rules circulating on this topic, but the safe approach is clearer: Stop training while you have symptoms of illness, and see a physician if necessary.

Exercise should be avoided in particular in the following situations:

Fever
Body aches, general weakness
Chest tightness, shortness of breath along with a cough
Gastrointestinal complaints, vomiting, diarrhea
Palpitations or an unusual sense of your pulse

With something like a mild runny nose, many people find light movement to be no problem; still, making the decision about your own situation together with your physician is the right route. Being considerate of other participants in the studio also matters: staying away from class while you have symptoms benefits everyone.

Returning after illness

Rather than going straight back to your previous intensity once you recover, progressing gradually is more comfortable. A practical approach: start the first week at about half your previous load, and if symptoms have cleared completely, increase gradually in the second week. If you experience unusual shortness of breath or palpitations on your return, stop and see your physician.

Practical ways to keep your routine through winter

A motivation problem is often not a question of willpower but of logistics. In winter conditions, removing obstacles is more effective than forcing yourself.

Move your class to an earlier hour. Leaving the house after dark in the evening is psychologically harder than leaving in the morning.
Prioritize indoor classes. A program that does not depend on the weather clearly reduces the number of cancellations.
Pack your bag in advance. Reducing friction at the moment of decision works.
Sign up for booked classes. A reserved class makes the “I could skip it today” option harder to take.
Find a training partner. Making a pact with someone who attends the same class regularly improves consistency.
Shrink the goal. If a target of 4 days a week does not hold, settle for 2; the difference between zero and two is bigger than the difference between two and four.

If you are going to train outdoors

A few simple points for those who want to keep walking or running in the cold:

Dress in layers; make the outer layer windproof
Keep your warm-up longer than usual
Thirst decreases in the cold, but your fluid needs do not
Account for slippery ground and adjust your pace accordingly
In very cold and windy weather, moving indoors makes more sense

For people with cardiovascular or respiratory conditions, exercising in cold weather may require extra caution; in that case you need to get your physician’s opinion.

Warming up matters more in winter

Starting a workout in a cold environment can make the warm-up time you are used to in summer insufficient. Because joint mobility and tissue flexibility are lower in the cold, extending the warm-up makes sense.

A warm-up structure that works for winter:

5 minutes general movement: marching in place, light cycling or the elliptical
5 minutes mobility: hip circles, shoulder opening, upper back rotation, knee raises
3-5 minutes activation: bodyweight squats, hip bridges, band pulls
Light sets of the main exercise: A warm-up set or two instead of jumping straight to your working weight

Coming in from the cold outside and launching straight into a heavy set is the most common form of poor preparation in winter. Arriving at the studio 10 minutes early largely solves this problem.

The order of dressing

Keeping on the thick layer you arrived in until the warm-up is complete is more comfortable for most people. Shedding a layer when you move into the main block and putting it back on during the cool-down is a simple but effective routine.

Nutrition and sleep

In winter, eating tends to become heavier and lower in vegetables, daylight hours shorten and sleep schedules drift. On these fronts, simple habits free of exaggerated claims are enough: a balanced and varied plate, adequate fluids, regular sleep hours.

When it comes to supplements, individual needs vary from person to person and no decision should be made without looking at blood values. It is best to consult your physician before starting any vitamin or supplement.

In short

The goal in winter is not to hit your best performance of the year; it is to enter spring with your routine intact. The way to do that is to distribute intensity wisely, rest while you have symptoms of illness, lean on indoor classes and reduce logistical obstacles.

If you would like to put together a class combination suited to the winter season around Maltepe and Dragos, you can get in touch with the club. If you have an existing health condition, getting your physician’s opinion before planning the program is the right order of operations.
