Something else that bothers me personally when I am in the Maldives, is equalising (the process of adjusting pressure in your sinuses whn scuba diving). With such world class snorkelling in the Maldives, it was some years after my wife started diving that I joined her in getting certified and one of the disincentives for me was general sinus issues which made for equalisation difficulties. For the 6 years I have been diving, these issues persist in irritating my dives, but over that time I have collected a range of tips from various divers and dive masters on how to alleviate the problem.
There are the classic tips that you learn when you get certified like…
- Wiggle ear and jaw.
- Hold nose and blow gently (I did find that a problem I had was trying to blow too firmly which both hurt my ears and wasted air).
- Descend slowly.
- Rise 2/10th metre when you start to feel discomfort.
Since taking the Scuba course, picked up the following added tips.
- Snort salt water. Before descending, suck some ocean water up through your nose. It actually works a treat to open up the sinuses. It’s not far off the traditional remedy for throat problems of gargling with salt water. However, Claudio at Sea Dragon Diving with Maafushivaru informs me that in most places that is a good trick, but in the Maldives there are many micro-organisms in the water the practice can cause infection. If you like this approach and are concerned about this, then you could bring some pharmaceutical saline solution with you.
- Sudafed. Or any non-drowsy cold decongestant. The scuba course will tell you not to take drugs for a number of good reasons (eg. they could have adverse side effect which is why you need to be careful to get non-drowsy ones, they could wear off and then problems could occur when you are in process of diving, they could mask serious issues or symptoms). In short, in the interest of absolute safety, the advice is that if you need any drugs to make diving comfortable, then you shouldn’t be diving. But, that advice is really geared toward people not well. If you are well, I have met a number of divers who do practice taking some Sudafed to assist the biological processes of opening up the sinuses and making equalisation easier.
- Swim parallel above rest of group. Many times it just takes longer for the equalization to happen. The problem is that you feel that you need to descend to keep up with your group and it is the rushed descent that causes the discomfort. The divemaster at Lily Beach Nicole encouraged me to simply swim above the group, but keeping the group in view, and descend at my own pace (also, in addition to my buddy, she kept an extra eye out for me).
