A major factor that influences the rate of evaporation is the relative humidity of the air around you. If the air is humid, then it already has water vapor in it, probably near saturation, and cannot take any more. Therefore, sweat does not evaporate and cool your body as efficiently as when the air is dry.
Finally, when the water in the sweat evaporates, it leaves the salts (sodium, chloride and potassium) behind on your skin, which is why your skin tastes salty. The loss of excessive amounts of salt and water from your body can quickly dehydrate you, which can lead to circulatory problems, kidney failure and heat stroke. So, it is important to drink plenty of fluids when you exercise or are outside in high temperatures. Sports drinks contain some salts to replace those lost in the sweat.
Sweating responds to emotional state. So when you are nervous, anxious or afraid, there is an increase in sympathetic nerve activity in your body as well as an increase in epinephrine secretion from your adrenal gland. These substances act on your sweat glands, particularly those on the palms of your hand and your armpits, to make sweat. Thus, you feel a "cold" sweat. Also, the increased sympathetic nerve activity in the skin changes its electrical resistance, which is the basis of the galvanic skin response used in lie detector tests.
Excessive sweating usually occurs on the palms of the hand or the armpits. If it is not caused by emotional or physical activity it is called "diaphoresis" or hyperhidrosis. It is often an embarrassing condition. The cause or causes are unknown. The condition may be due to the following:
The condition can be treated.
Adult Swim
Adult Swim (stylized as [adult swim] or shortened to [as]) is an American adult-oriented nighttime programming block of the basic cable network Cartoon Network that is programmed by its in-house production studio, Williams Street. Marketed as a separate network for ratings purposes, Adult Swim broadcasts nightly from 8 p.m. to 6 a.m. ET/PT.
Debuting in 2001, Adult Swim serves as the nighttime identity of Cartoon Network, and it was established as alternative programming during late night hours when Cartoon Network's primary target audience would normally be sleeping. By 2005, Adult Swim would be granted its own separate Nielsen ratings report from Cartoon Network due to it targeting a different audience. The block features stylistically varied animated and live-action shows, including original programming, syndicated series, anime, original video animations, and short films with generally minimal or no editing for content.
Adult Swim has frequently aired adult animation features, mockumentaries, sketch comedy, and pilots. The block's shows are known for their sexual themes, frank sexual discussion, nudity, strong language, and graphic violence. Many of its programs are aesthetically experimental, transgressive, improvised, and surrealist in nature. Adult Swim has contracted with various studios known for their productions in absurd and shock comedy.
WESC
WESC is a Swedish company. The company makes clothing, like jeans and shirts. Many people like these clothes, and they can buy them in many countries, for example in the United States, Japan and Germany. Because some famous people use the clothes, other people want to buy them too.
Ozámiz
Ozámiz is a city in the Philippines, in the province of Misamis Occidental. There were 141,828 people living there according to the 2015 census.
Ozámiz is named after Senator José F. Ozámiz, a hero of the Philippine resistance against the Japanese during World War 2.
Tillage
Tillage is the process in which soil is loosened and softened by tillers or harrows pulled by a tractor or by a plough pulled by an animal or human. The plough breaks the upper crust of the soil so that air and sunlight enter into the soil. This makes the soil more fertile but too much or frequent tillage may make it less fertile.
Yarmouth
Yarmouth could mean one of the following places.
In Canada:
In England:
In the United States:
Yarmouth, Nova Scotia
Yarmouth is a town in the province of Nova Scotia in the country of Canada. In 2011, the population of Yarmouth was 6,761.
Spleen
The spleen is an organ in vertebrates. The spleen is part of the lymphatic system. In people, it is on the left side of the body, under the heart. The spleen helps fight infections and keeps the blood cells healthy.
The spleen cleans out old blood cells from the blood and recycles them. It helps save the iron and the amino acids from the old blood cells. The spleen also holds a supply of extra blood, in case the body needs some quickly. The spleen works together with the circulatory system (the system which brings blood to the body).
A study published in 2009 using mice found that the spleen is a reservoir which holds over half the body's monocytes. These monocytes move to injured tissue (such as the heart after myocardial infarction), turn into dendritic cells and macrophages, and promote tissue healing. The spleen is rather like a large lymph node. Its absence makes certain infections more likely.
The spleen is shaped like a loose fist. It is tucked under the left side of the diaphragm, close by the heart.The average adult spleen weighs 0.44 lbs.
The spleen can get bigger when a person is digesting food or is sick. If a person's spleen gets big enough, it can break open. If this happens, the person needs medical care right away. Emergency surgery might be needed to control the bleeding.
Some of the diseases that cause the spleen to get bigger are:
In the past, many people believed the spleen helped control emotions. For example, if a person was upset or angry, people would think it was because of a spleen problem.
Placenta
The placenta is a temporary organ found in eutherian female mammals while they are pregnant.
The placenta is connected to the fetus by the umbilical cord, which is made of blood vessels and connective tissue. When the fetus is delivered, the placenta is delivered afterwards. The placenta is often called the afterbirth.
One of the placenta's jobs is to make sure blood from the mother and fetus never mixes. The placenta acts as an exchange surface between the mother and the fetus. Nutrients and oxygen are passed over by diffusion only. If the mother's and fetus's blood mixed, it could be deadly for both of them. If the mother and the fetus had different blood types, they might both die if their blood mixed.
The placenta has two parts, one of which is genetically and biologically part of the fetus, the other part of the mother. It is implanted in the wall of the uterus, where it receives nutrients and oxygen from the mother's blood and passes out waste. This forms a barrier called the placental barrier, which filters out some substances which could harm the fetus.
However, the placental barrier is not able to protect the fetus from everything that could hurt it. For example, alcohol goes through the placental barrier into the fetus. This is why drinking alcohol during pregnancy can cause Fetal Alcohol Syndrome. The placenta is also unable to filter out many other things. Chemicals that can cross the placental barrier and hurt the fetus are called teratogens.
Some infectious diseases may also cross this barrier and infect the fetus.
Prototherial (egg-laying) and metatherial (marsupial) mammals produce a type of placenta that provides nutrients mostly from the egg sac, instead of from the mother's blood. It is positioned in the female's body similar to eutherian mammals. Some snakes and lizards have evolved a system of internal development with a placenta-like tissue: this is an example of convergent evolution.
