In the eastern part of the country it rains more than in the west. There are three temperature zones in Nicaragua. In the lowlands (Pacific and Atlantic coast) temperatures vary roughly between 72Â° F at night and 86Â° F at daytime (22Â° C - 30Â° C). Temperature can reach 100Â° F in May (38Â° C).
Dark circles, or bags under your eyes, have many causes. These include: 1  Increased melanin (also called hyperpigmentation) also post-inflammatory hyperpigmentation due to allergies ('allergic shiners'). 2  Fat loss beneath the eye or shadowing due to skin laxity. 3  Broken blood vessels.
Under-eye bags are caused by the protrusion of the pad of subcutaneous fat that exists under the eye area. This is caused by a thinning of the skin as one ages and by the loss of firmness and elasticity due to the breakdown of collagen, elastin and hyaluronic acid.
