What is Interbout Euthermia?

What is Interbout Euthermia?

Interbout euthermia is characterized by metabolism, blood flow and body temperature typical of a homeothermic mammal of similar size (Drew et al., 2004).

What are Interbout arousals?

During the hibernation season, animals oscillate between periods of torpor and periods of interbout arousal (IBA). During torpor, body temperature is often near 0° C and metabolism is severely depressed. The transition period between these two physiologically dissimilar states is called arousal.

What does daily torpor mean?

Torpor enables animals to survive periods of reduced food availability. The term “torpor” can refer to the time a hibernator spends at low body temperature, lasting days to weeks, or it can refer to a period of low body temperature and metabolism lasting less than 24 hours, as in “daily torpor”.

Why do birds go to daily torpor?

It happens when an animal slows its body functions to conserve energy and heat. The bird’s heart rate will slow; so does its breathing and body temperature. Several species of birds can go into brief states of torpor to conserve energy: hummingbirds, doves, and the poorwill’s close cousin, the Whip-poor-will.

What is the difference between torpor and Estivation?

Estivation is a similar form of dormancy in a dry and hot environment during summertime. Daily torpor is defined as reduced MR and Tb lower than 32 degrees C, limited to a duration of less than 24 h. The only difference between hibernation and daily torpor was found in the bout duration.

Can humans go into torpor?

Even though humans don’t typically go into torpor of their own volition—and our bodies typically prevent it by shivering—Drew explains that there’s no single “hibernation molecule” or organ that humans lack. In fact, torpor can be induced by doctors in extreme circumstances.

How long can torpor last?

It can last <1 day, may occur for a few consecutive days, or may last an entire season or even many years. Torpor involves physiological changes related especially to body temperature, metabolism, and water balance.

Is torpor the same as sleep?

In many heterothermic species there is a relation between torpor expression and the repartition of the different behavioral states of sleep. Despite the presence of sleep during this period of hypothermia, torpor induces an accumulation of sleep debt which results in a rebound of sleep in mammals.

What is Estivation in ecology?

Estivation is summer dormancy, that is, long-term torpor during summer for survival of hot and dry periods. Many desert plants survive extended periods of high temperature and low rainfall. Amongst vertebrates, fishes, amphibians, and reptiles enter a similar estivation state.

What is Estivation and hibernation?

Brumation is known as the hibernation for cold-blooded animals. Estivation is when animals are dormant because weather conditions are very hot and dry. Their breathing rate, heart rate and metabolic rate decrease to conserve energy under these harsh conditions. These animals will find a spot to stay cool and shaded.

What is Lotska?

At the first fall of snow the whole family gathers round the stove, lies down, ceases to wrestle with the problems of human existence, and quietly goes to sleep. This winter sleep is called lotska.

What would happen if humans hibernated?

The longest duration therapeutic hypothermia is tested is two weeks. But a body temperature lower than 2.7 degree Celsius can cause several complications including weaker digestion and immune system. So, hibernation in humans can cause brain damage, memory loss, weaker immune system and indigestion.

What is euthymia and how does it affect you?

Euthymia is dramatically different from the periods of sadness and hopelessness that you feel when experiencing depression, or the extreme peaks of energy you experience when in a state of mania. While the experience of euthymia varies from person to person, some of the more common signs that you’re in a euthymic mood include feeling:

What is euthymic state in bipolar disorder?

It’s commonly associated with bipolar disorder. While in a euthymic state, one typically experiences feelings of cheerfulness and tranquility. A person in this state may also display an increased level of resiliency to stress.

What does reactive euthymic state mean?

Euthymia with reactive affect. A reactive affect in a euthymic state means that you respond appropriately to the subject of a conversation. Euthymia with congruent affect. Congruent euthymia is evident when your emotions match the situation.

What is the meaning of congruent euthymia?

Euthymia with congruent affect. Congruent euthymia is evident when your emotions match the situation. In other words, the emotional reaction you have is congruent or in agreement with the situation you’re experiencing. Treatment considerations for bipolar disorder
