In extreme cases snoring can develop into sleep apnoea – a condition where some people can stop breathing for short periods up 60-100 times per night. When levels are as high as this it becomes a serious medical condition and can obviously be very dangerous.

Alcohol is a well-known relaxant, which can cause a softening of the tissue in the throat, which will nearly always have a noticeable effect on the snorer.

Excessive consumption of dairy products can stimulate excess mucus and raise the incidence or level of snoring in sufferers. Increased weight can have an effect too because over-eating leads to an enlargement of the neck which, when lying down, can compress and restrict the airways. Research shows that men with larger collar sizes are much more prone to snoring.

Whilst asleep, our breathing and heart rates slow and the muscles relax. In the throat this causes the soft palate (a small flap of skin) to become limp and flaccid and this reverberates in the airflow induced by breathing and brings about the sound we know as snoring.

The spray works by ‘re-toning’ this soft tissue and making it taut again, so that it cannot reverberate and cause the problematic snoring sound.

Yes it would, because smoke inhalation (rather like hay fever) aggravates snoring conditions by encouraging the body to produce excess mucus, which can contribute to the restriction of the nasal airways.
