Should you skip or keep your workout if you're sick? Here's how to tell

PBS host Stephanie Mansour, of "Step It Up With Steph," demonstrates a mindful breathing exercise that will help you release negativity or stress with each breath.

(CNN)As a personal trainer and yoga and Pilates instructor, I like to provide a wide variety of exercises and workouts that people can do regardless of their situation, health limitations or mood. So my clients ask me this question all the time: If I feel sick, should I exercise or rest?

The immediate answer is complicated, but with an assessment of your symptoms, you'll have the confidence to decide more quickly. And, if the answer is to skip your workout, there is still an exercise or two that you can do to help you feel less sick.
With cooler winter temperatures in full force, cold and flu season is here. On average, Americans have two or three colds every year, according to the US Centers for Disease Control or Prevention. This may wipe you out for seven to 10 days per cold. If you add in other symptoms, like an upset stomach, a fever or a cough, you may be looking at even more downtime.
    Here are the five most common scenarios if you've fallen ill -- and how you can decide if you should exercise or take it easy.
      Important note: Be sure to seek advice from a health care provider if you have lingering or persistent symptoms and also prior to starting a workout program.

      Head cold

      Work out. If your symptoms include common ones like a runny nose and congestion, just scale back your workout to make it less intense. Working out with a cold may actually help relieve nasal congestion and open up your nasal passageways.
        Instead of doing a high-intensity workout, try doing a lower-impact strength-training workout. Or instead of going for a run or jog, go for a brisk walk. Simply pare down your workout so that it's less intense and takes less time than usual.


        Skip. Working out while you have a temperature can actually increase dehydration and raise your internal body temperature even more. Also, with a fever your muscles are already more fatigued and have less strength, so it's best to give them a rest.
        Instead, try doing a yoga pose called Savasana with lots of props. Lie down on the ground. Place a bolster or pillows underneath your knees, and a pillow underneath your head. Relax your arms by your sides with the palms face up.
        Close your eyes, and slowly breathe in through the nose and out through the nose for at least two minutes. Meditating while deep breathing has a soothing effect on the nervous system and helps calm the body and the mind.

        Sore throat

        Work out. Typically when a sickness is above the neck, it's OK to exercise at a less intense pace. Make sure to drink plenty of water to soothe your throat both before, during and after exercise. Slow down your pace (like you would if you had a cold).
        If your sore throat is accompanied by a fever or body aches, however, take a break.

        Skip. Especially if this cough is coming from your chest and accompanied by mucus, definitely skip your workout. Frequently coughing can prevent you from being able to catch your breath properly during a workout and make it difficult to take a deep breath when your heart rate increases during exercise.
        Instead, engage in a forward-fold stretch to improve circulation and relieve coughing symptoms. It's a stress-relieving exercise that invigorates your nervous system and literally turns your head upside down.
