Exercising & a Hard Time Breathing While Lying Down

Lying down right after you exercise is a risky idea because it can make it difficult to breathe and cause your heart rate to soar. In most cases, a good cool-down routine can help you slow your heart and respiration rates after exercise. However, not all breathing difficulty is caused by exercise, so you should always consult your doctor when you struggle to breathe when lying down.

  1. Exercise, Breathing and Heart Rate

    • When you exercise, your heart and respiration rates increase to supply blood and oxygen to your muscles. More intense exercise tends to elevate your heart rate and breathing more, so if you lie down immediately after working out, you may have trouble catching your breath. According to the Cleveland Clinic, lying down immediately after exercise can cause heart palpitations. These palpitations may make breathing more difficult or make you feel like you can't catch your breath.

    A Proper Cool-Down

    • Cooling down after an intense workout can help your respiration rate return to normal, making it easier to breathe and relax when you finally do lie down. Consider taking five to 10 minutes to stretch, since your muscles will already be warm and you'll be at less risk of injuring your muscles while stretching. A slower, less intense version of your workout routine can also work well. For example, if you're a runner, try slowing to a jog and then to a walk, or if you've been cycling, try taking a leisurely bike ride for five to 10 minutes.

    The Role of Dehydration

    • If you don't drink enough water or sweat profusely, you could be dehydrated immediately after your workout. Dehydration can alter your heart rate, leaving you feeling winded, and can elevate your rate of respiration, making you feel like you can't catch your breath. Try drinking an electrolyte drink, and always drink plenty of water before, during and after your workout. If your symptoms last longer than a few minutes, though, call your doctor.

    Other Health Problems

    • If you have trouble breathing when you're lying down, exercise might not be the problem. Conditions such as congestive heart failure, asthma, infection, lung disease, exposure to environmental pollutants and a host of other conditions can lead to difficulty breathing. If you regularly struggle to breathe when lying down, keep a log of your symptoms and call your doctor.
