A small gas leak in your home can be difficult to detect. Low-level exposure to natural gas can cause mild headaches and a feeling of breathlessness when you exert yourself during physical activities. Headaches and breathlessness can also be caused by a variety of other issues, including allergies or illness.
If the symptoms go away in the fresh air you could be feeling the effects of a gas leak or carbon monoxide poisoning. There can also be some clear signs from your household appliances that can indicate a leak, even if you can't smell gas: Always look for a crisp blue flame, rather than an orange or yellow flame.
