numb to the outside world but that’s not do the senses (touch, hearing, taste, sight, smell) and other aspects can affect or prevent our sleep?While sleeping, you may believe that you become numb to the outside world but that’s not true. Many aspects outside the mind can disturb or comfort the person and can use this to make better use of the time that we have to sleep so that we can get the most out of the night.The Senses:Touch, hearing, taste, sight and smell are the five senses that were taught to us at the very beginning. So I had wondered whether the senses can still be triggered while people are unconscious in their sleep and how can they prevent sleep from taking place. From past experience, I know that people can be woken up from a touch or from a loud noise, besides that, I can’t recall any other moments that relate to waking up aside from it occuring naturally.People are most prone to waking up in the early stages of their sleep TouchBedOur sense of sleep can greatly affect our sleep. When trying to fall asleep, the firmness or softness of the mattress you are sleeping on, the sheets resting on top of you, to the soft pillow that you sleep on con completely distract our attention to the discomfort resting on the bed. Whether you like firm or soft mattresses and pillows, it’s all about your specific preference.TemperatureHumans are able to control their body temperature and the body is known to lower it during the night while we sleep. Researchers believe that the reason to this would be that the body needs to conserve energy for other functions in the body. But when the temperature in the room is too cold or warm, it can cause discomfort and restlessness and fragmented sleepSightLight and DarknessWhen this is minimal light present in the room, the brain sends an important signal that notifies the body that it should begin to get ready to sleep. This is “the clock” that the body follows each day to determine whether it is day or night.  The darkness will trigger melatonin, a hormone produced by the brain’s pineal gland, arouses the start of sleep by sending a signal to the brain. The brain then relaxes the body’s muscles, signs of drowsiness increase and body temperature drops.ElectronicsThe amount of artificial light that we have available in our homes can provide us with more capabilities and time get more done during the day. LED lights can be found in many devices and can be helpful in many ways, nevertheless, there will be negative aspects as well. All the man-made light that people are exposed to can disrupt the natural sleep pattern. This is determined by the amount of light and darkness exposed to the body. This is called the circadian rhythm. It controls the sleeping and eating times, and brain activity such as, hormone production and cell regeneration. But when light can be detected throughout the whole day, the rhythm does not know the time of the day it is currently and results in being unable to identify the time it is to sleep.The blue light can be found in many devices in modern society. Although all types of lights can lower the effect of melatonin, blue light is much stronger. The result of having lower melatonin than normal can be have a difficult time falling asleep and being alert at late hours. Harvard University had organized a study about blue light. They had wanted to compare the effects of blue light to green light. The results had soon been revealed that blue light had disrupted the circadian rhythm two times more that green.Room FormatWhen staying in a room, colour can play a major part when a person is about to fall asleep. Although most of the time people will fall asleep in the dark, there will be points in time when we are taking a nap in the afternoon after lacking sleep from the last night. Colourful and bright colours can look fun, but can be very distracting when trying to fall asleep. Soft pastel colours can be a better alternative as it is very calm and peaceful to look at.Having a messy room can largely impact the impression and the atmosphere in the bed chamber. It can cause anxiety, stress and a higher chance of mental illness which can overall result in lack of sleep. All the clutter can confuse and distract our attentions from the central focus. With everything filling the brain, it is difficult to clear the mind and relax. Stimuli continuously strikes the brains and causes our senses to focus on irrelevant stimuli. We will be constantly be reminded of the unfinished projects and work that the mess represents and the amount of time that the work will consume. Guilt rises when noticing the mess, believe that we should be more organized and neat. All these elements has the capability to stress us and to prevent people from having a restful night.`HearingEveryone has different preferences on what they consider peaceful and disturbing noises. It is important to welcome favourable sounds and avoid racket. The sounds waves that we receive can largely impact our sleep from abruptly waking up from a heavy thud to awaking from the soft footsteps of a child.The sense of hearing will always be active during sleep, however, the sensitivity, from waking up from a noise, will differ among particular people as suggested from a loud factory worker being able to sleep easily when a loud noise is present.Noise PollutionOutdoor sounds, in particularly noises generated from transportation, is perceived as a significant disruption to people asleep. According to a study written by Demian Halperin,  Poor sleep causes endocrine and metabolic measurable perturbations and is associated with a number of cardiometabolic, psychiatric and social negative outcomes both in adults and children. Environmental noises, that occur during very late hours, can quickly stimulate an measurable increase in stress levels, disrupt the structure and quality of sleep. People who struggle with these occurrences are often to wake up sleep deprived. However, with more research being done, it is evident that when experiencing nocturnal environmental noises for long periods of time can lead to long-term adverse cardiometabolic outcomes.SmellAllergiesIn the season of allergies, sniffling and coughing can be the reason why people are unable to fall asleep. This will then lead to lack of sleep and struggling to keep awake during the day. However, in a study done by ResMed, results show that there is no difference in the sick’s performance while comparing to the non sick. TasteBecause there is such a wide range of different types of foods and drinks, it is difficult to determine all the ways that sustenances can impact our state of being unconscious. From a large dinner to a light midnight snack, food can either hinder or encourage sleep to occur. FoodFoods that we consume can lead us to having a easy and restful night or a struggle to fall asleep. Tryptophan is an essential amino acid,also known as L-tryprophan, and is able to create and balance specific hormones naturally. Eating food that is rich in tryptophan can aid to relaxing the mind, encouraging sleep, and resisting against anxiety and stress. Likewise, the acid has been found to help burn more fat, releasing more growth hormones, reduce food cravings and there had been evidence of ending a sugar addiction in some cases. From tryptophan, the body   produces serotonin, 5-HTP and melatonin and a large group of structural proteins and other essential biochemicals, such as vitamin B3.
