Screen Time Before Sleep Can effect Sleep

Screen-time just before sleep leads to a bad nights sleep and leaves you groggy the next morning. We all know that blue light is bad for sleep already. But, screen time before sleep tends to affect your body clock as per a researcher. The body clocks natural cycles intimate us about sleep and waking up times. Also known as Circadian rhythms, they find help from the light of the day and night for keeping their internal body clock running over a 24 hour cycle.

The fact that the electronic gadgets are around us round the clock makes their use and hence exposure to blue light all the more evident. Now, the study was conducted over 19 subjects in their 20’s. Everyone had to spend around 2 hours before bed time on computer screens. The results obviously varied between students because the computer screens were not all the same. The were tweaked. Some screens emitted soft blue light, while some emitted intense blue. Some of them emitted intense red and some soft red as well. This was done to check the effect of each one. Even after the subjects went off to sleep, the researchers recorded how many of them work up and how many of them slept all through the night. Further the researchers also note down the sleep phase called REM (short for rapid eye movement) and even asked the subjects themselves about their sleep experience.

The researchers observed that the subjects who were exposed to intense blue light suffered sleep issues for around 16 minutes as compared to the ones who were exposed to red light. They even woke up through the night more often than the red light exposed subjects. The researchers observed that the blue light emissions from the computer effected melatonin, the sleep hormone of each subject. This hormone is responsible for making us sleepy and is secreted around 9 pm in the blood. Now, the blue light restricted the melatonin secretion and hence the subjects exposed to intense blue light felt alert to fall asleep even if they were tired. Those exposed to red light did not find any such issues.

Well, the researchers through this study brought forward the fact that the intense blue light emissions from computer screens just before sleep time does affect the body clock. Though the light used for the study was extremely bright that generally the TV or tablet or computer emits, there is no cent percent surety of the damage it causes.

Nose and Emotions - The Inter Relationship

Now, here is some news related to the ability to expressing emotions. A study has found that the rare condition experience by 10% of the healthy population called alexithymia leads to difficulty in understanding emotions, talking or relating to them or even expressing them.

The researching scientists adopted a completely untested approach of study which included testing 62 individuals divided into categories based of severity of alexithymia as low, medium and high. The testing was known as olfactory tests and were carried out to find out their reactions on different kinds of stimulation.

The scientists were also explained the reason behind using the olfactory test’s suitability in studying this psychological conditions. According to them, between the areas in the brain there is a partial develop that deals with olfactory perception besides with those that are into processing emotions.

One of the important finding of the test were that scientists found the alexithymic patients react differently than others when it comes to smells. Apparently, its a result of their psychological parameters like accelarated heart rate or electrical skin conductivity. Additionally, the scientists also observed difference in reactions in subjects suffering from affective alexithymia and effective alexithymia wherein the areas of imagination, sensation and creativity are restricted compared to subjects with congnitive alexithymia, wherein identification, expression and distinguishing ability is compromised.

The results clearly stated that altered psychological response to olfactory stimuli is one of the characteristics of alexithymia. The test also brought to light an interesting fact that The psychological reactions of individuals suffering from alexithymic conditions to smell induced emotions are apparently more intense, contradicting general expectations on the same.

A significant observation as it may be and counter intuitive too, subjects with alexithymia become insensitive to difference, changes or color shades that are said to enrich our routine lives scientifically due to the situation of extreme perpetual activation with respect to emotions, they are said to be in.

Carl G Jung is the one whose indent curiosity led to finding about personality types as per the following –
Introverted or Extroverted
Sensing vs Intuition
Thinking vs Feeling

Introverted, Sensing, Thinking, Judging

Jung’s area of preferences are dichotomes viz bioplan dimensions wherein every pole represents a distinct preference. Jung did state that one of the aforementioned four functions are present in a person be it judging or perception. Further more one of the researchers called Brigs Myers proposed a fourth dichotomy as Judging vs

Perceiving. According to her the personality criterians are as follows -

2. Sensing – Intuition – It symbolizes how someone perceives information. Sensing represents a person who believes in information obtained for the real or external world while intuition represents

3. Thinking – Feeling – It depicts how people process information. They either do it based on logic viz thinking or based on what they feel like doing about it.

4. Judging – Perceiving – It represents the implementation of the received information after processing it. Judging is when a person will organize all life events and will stick to all the plans. Perceiving is more about exploring alternatives and improvising on existing ones.

The above four dichotomies are said to yeild 16 different personality combinations or types wherein it represents either of the two poles in each dichotomy of the four dominated in a person, thus deriving 16 separate personality types. To study more about the personalities or denote personality types often every type is assigned a 4 letter acronym. For example
