Are there any beneficial effects of breathing negatively ionised air?

Thank you for your question. There can be many reasons why someone would experience excessive daytime sleepiness. As the potential causes are varied and have been well-covered by both Dr Tze Yong and Dr Ethan, I shall not be repetitious. One of the most common cause of excessive daytime sleepiness (if you do not have poor sleep habit, sleep deprivation, insomnia and medical problems or are on medications that disrupt sleep) is Obstructive Sleep Apnoea or OSA.

Perlane fillers can be seen on CT scan as soft tissue at the location where it’s injected, especially if it’s injected as a bolus. Fret not, the radiologist and radiographer would have seen many such cases, so do not expect them to be surprised at the findings. In fact, you can let the doctor know this, so that the radiologist doesn’t mistake it as other structures in his interpretation of the scan.
