Avoid Doctor Waiting Rooms and Hospitals By Improving Sleep

Although all doctors have put in strict measures at their practices to avoid patients with suspected COVID-19 from sitting around in waiting rooms it is still a good idea to limit your visits to medical rooms or hospitals unless absolutely necessary. Social distancing is much harder to do in a medical environment too, so avoiding hospitals is important unless absolutely necessary. Poor sleep can contribute to you having to visit a doctor more regularly.

Amid COVID-19 Is Sleep Still A Priority?

Sleep is critical. All we have to fend off COVID-19 is our immune system – those are the cells that attack any foreign object in order to protect us. The other part of the immune system comprises of antibodies and no one has inbuilt antibodies against this virus because it is brand new. So it’s up to our own immunity until a vaccine can be developed in the future.

How to Test for Sleep Apnea During COVID-19

Right now, and probably for the next year at least, we want to avoid hospital admissions if the tests we require can be done at home. While doctors diagnose and manage COVID-19 that doesn’t mean that you must not look after your general health, particularly if you suffer from diabetes or insulin resistance or any type of cardiovascular disease.

Letters from Dr Bentley: Interesting Information about Obstructive Sleep Apnea

Dear Colleague

Welcome to our short newsletter which gives you some (hopefully) interesting information about obstructive sleep apnea.

It can be quite challenging to decide which patients to screen for obstructive sleep apnea (OSA) as the perceived prevalence is quite low. This is incorrect – the prevalence in the adult population ranges between 10 and 24% increasing to 49% in people over 65 years. Read more

The Long-term Consequences of Obstructive Sleep Apnea.

Obstructive sleep apnea causes a person’s throat to close momentarily during sleep, due to an abnormality in pressure in the back of the throat. When this happens, the brain is alerted to wake up, often multiple times at night, to restart breathing. It also means a person may experience a drop in oxygen levels. And, both of these can have long-term consequences on your health.

The Short-term Consequences of Obstructive Sleep Apnea.

Obstructive sleep apnea is a momentary closing of a person’s throat, usually because of an abnormality in pressure in the back of the throat. The result is that a person’s brain is alerted to wake up, sometimes multiple times a night, to restart breathing. They may also experience a drop in oxygen levels, as the lack of breathing means the lungs have not received the oxygen-rich air they need. But, what consequences can that have in the short-term?

What is Obstructive Sleep Apnea?

Let’s start by understanding that, in general, sleep apnea refers to the halting of breathing during sleep. There are two types of sleep apnea. One is called central sleep apnea, which is caused by a malfunction in the brain, where it “forgets” to breathe. This type of apnea is very uncommon and happens without snoring, mostly in babies and the elderly. A more common type is obstructive sleep apnea – which means the back of the throat collapses in on itself while breathing in, usually due to an obstruction in the area.

What a snore! Why your snoring can be more than just a bad habit.

Many people snore (up to 40% of men over 40 years of age) but only a small proportion of those people have sleep apnea. While snoring indicates a partial blockage to air flow it is more of a problem for your sleeping partner! Sleep apnea, however, is a medical disorder that has significant consequences to your heart health and left untreated increases your risk of heart disease as well as diabetes.
