When you're short of breath, it's hard or uncomfortable for you to take in the oxygen your body needs. You may feel as if you're not getting enough air. Sometimes you can have mild breathing problems because of a stuffy nose or intense exercise. But shortness of breath can also be a sign of a serious disease.

Many conditions can make you feel short of breath:

• Lung conditions such as asthma, emphysema, or pneumonia
• Problems with your trachea or bronchi, which are part of your airway system
• Heart disease can make you feel breathless if your heart cannot pump enough blood to supply oxygen to your body
• Anxiety and panic attacks
• Allergies

If you often have trouble breathing, it is important to find out the cause.

Your nose is important to your health. It filters the air you breathe, removing dust, germs, and irritants. It warms and moistens the air to keep your lungs and tubes that lead to them from drying out. Your nose also contains the nerve cells that help your sense of smell. When there is a problem with your nose, your whole body can suffer. For example, the stuffy nose of the common cold can make it hard for you to breathe, sleep, or get comfortable.

Many problems besides the common cold can affect the nose. They include:

• Deviated septum - a shifting of the wall that divides the nasal cavity into halves
• Nasal polyps - soft growths that develop on the lining of your nose or sinuses
• Nosebleeds
• Rhinitis - inflammation of the nose and sinuses sometimes caused by allergies. The main symptom is a runny nose.
• Nasal fractures, also known as a broken nose
