Do allergies affect our sleep?

Allergies can affect sleep because they can disturb how someone feels. But the importance of allergies, or conditions to think about— say, asthma, which is an important one, can have quite a devastating effect on sleep during the night. May not necessarily wake the person, but will cause a lot of tiredness and fatigue the next day, so it's worth keeping an eye on. Over and above that, in fact experimentally, one can look at the affects of antihistamines' various responses on sleep. If the antihistamine is effective, then sleep will improve.
