It May Be Better for Regulating Body Temperature
Darker colors are especially effective since they absorb more heat and light than brighter colors. Black—which actually isn’t a color, but the absence of color—absorbs the most light, reflects very little, and therefore traps in the most heat for the wearer.
Can you scuba dive at the Titanic?
No, you cannot scuba dive to the Titanic. The Titanic lies in 12,500 feet of ice cold Atlantic ocean and the maximum depth a human can scuba dive is between 400 to 1000 feet because of water pressure.
How deep can a diving suit go?
An atmospheric diving suit allows very deep dives of up to 2,000 feet (610 m). These suits are capable of withstanding the pressure at great depth permitting the diver to remain at normal atmospheric pressure. This eliminates the problems associated with breathing high-pressure gases.

What is the deepest saturation dive ever?
In 1992 Comex, a French diving company, conducted a series of experimental dives to 2,133 feet (650 meters) of seawater in a hyperbaric research chamber in France. For two hours one diver went to 2,300 feet (701 meters), which is the deepest a human has gone under pressure (71.1 atmospheres) to date.
How deep can a human dive without scuba gear?
That means that most people can dive up to a maximum of 60 feet safely. For most swimmers, a depth of 20 feet (6.09 metres) is the most they will free dive. Experienced divers can safely dive to a depth of 40 feet (12.19 metres) when exploring underwater reefs.
