Diving is quite safe as long as you know how to follow certain safety precautions that are usually imparted by guides and dive masters before an open water dive. One of them is to forego diving when you are not comfortable with the parameters of the dive or having some problems with your respiratory tract or nasal area. This makes equalizing difficult. You should also be aware of the hand signals of your dive master or guides. They could be warning you of a potential danger in the form of an obstacle or a poisonous marine creature. You should also remember to ascend slowly while breathing normally. After a dive, head to the hospital immediately if you feel any unusual symptoms like tingling or numbness in any part of your body. Also, when packing for the trip, always include a first aid kit. With these things in mind, diving does not have to be dangerous.
