Dehydration is another concern. Hydrating well before entering the water is highly recommended, especially if one intends to snorkel for several hours. Proper hydration also prevents cramps. Snorkelers who hyperventilate to extend sub-surface time can experience hypocapnia if they hyperventilate prior to submerging. This can in turn lead to "shallow water blackout". Snorkeling with a buddy and remaining aware of the buddy's condition at all times can help avoid these difficulties.

Attached to the demand end of the snorkel at the bottom of the barrel, the mouthpiece serves to keep the snorkel in the mouth. It is made of soft and flexible material, typically natural rubber and latterly silicone or PVC. The commonest of the multiple designs available features a slightly concave flange with two lugs to be gripped between the teeth (see Figure 9):
Some commercial snorkeling organizations require snorkelers at their venue to wear an inflatable vest, similar to a personal flotation device. They are usually bright yellow or orange and have a device that allows users to inflate or deflate the device to adjust their buoyancy. However, these devices hinder and prevent a snorkeler from free diving to any depth. Especially in cooler water, a wetsuit of appropriate thickness and coverage may be worn; wetsuits do provide some buoyancy without as much resistance to submersion. In the tropics, snorkelers (especially those with pale skin) often wear a rashguard or a shirt and/or board shorts in order to help protect the skin of the back and upper legs against sunburn.
The bikini finally caught on, and by 1963, the movie Beach Party, starring Annette Funicello and Frankie Avalon, led a wave of films that made the bikini a pop-culture symbol, though Funicello was barred from wearing Réard's bikini unlike the other young females in the films. In 1965, a woman told Time that it was "almost square" not to wear a bikini; the magazine wrote two years later that "65% of the young set had already gone over".
With the dredging and development of Mission Bay and the dismantling of the Ocean Beach-Mission Beach bridge, O.B. became geographically isolated from the rest of San Diego and the other beach communities, until the construction of Interstate 8 in 1967. The westernmost segment of I-8 from Interstate 5 to the terminus in Ocean Beach is officially labeled the "Ocean Beach Freeway".
