Understanding histamine release at night

If you react badly to mozzie bites, then you’ve probably taken anti-histamines to relieve the swelling and itching.

But what is histamine anyway? And what are the symptoms of a histamine release at night?

Histamine’s role in your body

Histamine is found in many foods but it’s also a chemical your body produces. It performs a few important functions, including:

  • Helping your immune system respond to allergy triggers
  • Triggering a pain response when your body is harmed
  • Widening your blood vessels to increase blood flow
  • Increasing stomach acid production to maintain typical acidity
  • Helping produce mucus in your airways – and increasing it to help capture allergens
  • Tightening the muscles in your airways to restrict airflow in and out of your lungs.

So, if histamine is so useful, what’s the problem with it?

The problem with high histamine levels

If you’re intolerant to histamine, your body is not able to break down histamine properly, due to the absence of an enzyme called diamine oxidase (DAO).

When histamine builds up in your body, you may experience uncomfortable symptoms like:

  • Gastrointestinal issues – diarrhoea, bloating, nausea, vomiting
  • Headaches or migraines
  • Low blood pressure or an irregular or fast heart rate
  • Painful periods
  • Eczema
  • Runny or stuffy nose
  • Feeling short of breath
  • Swelling of your lips, tongue or throat.

Then there’s sleep…

The influence of histamine levels at night

Eventually, your body may release the excess histamine into your bloodstream. These releases often happen late at night or early in the morning, potentially compromising your sleep.

Perhaps you’ve noticed that your allergy symptoms get worse at night? Symptoms of a histamine release at night include:

  • Changes in body temperature
  • Itchy skin
  • Blood pressure changes

Histamine regulates sleep-wake cycles meaning that a histamine release at night can mean you wake up far earlier than you’d like to. When your sleep is regularly compromised, you begin to feel worn down and tired. That can affect many different aspects of your life.
