Conservation was an idea that the theorist Webb came up with he suggested that those animals that slept more were more likely to survive such as hedgehogs.Conservation is where the body slows stamp out the metabolism and heart rate as no food is world consumed and no energy is being used up as the animal is not moving a play. Webbs theory is linked to hibernation mostly as his theory is more suggesting the likelihood of surviving due to resting. By olfactory modalitying at both theories I can now come to the conclusion that the restoration theory is more logical in its use of energy as it suggests that the more energy you use up in the day the more you look forward to going to bed to resto re tissue and save energy.It also suggests that even if you dont fully employ yourself in a day it doesnt mean that your not going to quietness for long and this can be fully evident in teenagers as even if they do or dont exert themselves they still residue a lot more as there bodies are developing and they need more calmness then the rest to gain in energy and also to give there bodies a time to relax as there bodies will be constantly secreting hormones.The ready and effect of insomnia still arent open(a) as the Pineal gland in the brain converts the neurotransmitter serotonin into the hormone melatonin. Melatonin is released into the blood stream and causes throbbing changes around the body although the need for sleep is not affected by light. Melatonin plays a role in the co-ordination of the sleep wake cycle. So as sleep isnt affected by light then the cause of insomnia cant be known as you cant determine what effects the body that causes insomnia.REM sleep involves an increase in energy expenditure and blood flow which inhibits protein synthesis on the other bridge player it is known that amino acids are not stored by the body and last in the body for bout 4 hours later on a meal. This means that protein synthesis maybe stopped half way through and through sleep because the amino acids have run out. as well as people will sleep more after stress and it is known to improve moods which again can be explained by the fact that with NREM sleep occurring during slow wave so enables the body to repair itself and there is an increase in secretion of harvest hormones.By looking at the evolutionary theory I can also conclude that the arguments presented for the evolutionary theory contradict themselves as some suggest that some animals sleep less to keep a vigil while others suggest that animals sleep longer to keep motionless thus staying away from harm. Also it is clear to see that animals such as lions do sleep longer as they are at less of a risk f rom being hunted so dont need that much sleep and animals like cattle need very little sleep and this puts them in danger of being hunted.
