Screen Time Before Sleep Can Effect Sleep

In the present times when screens are very much becoming an integral part of our routines lives and most of the day you are hooked to your laptop, computer or PC, here’s some news around effects of screen time just before sleeping.

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

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.

Well, now you know how nose and emotions are interconnected or interdependent for that matter.

Dementia Risk and Blood Magnesium Levels

Before we talk about risk factors associated with dementia lets just polish our information around the condition. This condition usually occurs at an older age and causes memory loss. Alzheimers is one of the most common forms of dementia known. Apparently, its not a condition by a symptoms or group of symptoms rather. You should also know that it does hamper our day to day routines because we tend to forget a lot. Dementia symptoms are also caused due to vitamin deficiencies and thyroid problems. Dementia occurs due to brain cell damage and most of them are generally permanent or increase with time.

Dementia Risk and Blood Magnesium Levels

Now, a study has found out that the levels of magnesium in your blood can associated to the risk of dementia later in life. The people with lower or higher levels of minerals in the body were subject to dementia more compared to the ones with middle levels. It has yet to be proved and nowhere confirm that it causes dementia but definitely magnesium levels do have a link with dementia. There are apparently two ways in which magnesium levels could be called as risk factor for dementia.

Coming back to the study, around 10,000 participant around 65 years of age were studied across 8 years span and their magnesium levels were checked at the beginning of the test. They were divided in 5 groups. The study findings showed that those with low and high level magnesium had 30% greater risk of dementia compared to mid level magnesium level participants. The lower and higher magnesium range is below 0.85 millimoles per liter and 1.10 mmol/L respectively. Though as the magnesium levels were not measure post eight years the results could have associated limitations.

Well, to prove that magnesium levels do determine the risk of dementia in later stages of life, further detailed study is required.

Tatoo Ink and Side Effects – A Short Review

Tatoo Ink and Side Effects

Before we get to the question that whether tatoo ink is harmful to the body or not just quickly understand the process through with tatooing is carried out. The tatoo artist, to make a permanent tatoo uses hundreds of needles for pricking into the skin and delivering ink into the dermis. Now, dermis as well know lies below the epidermis layer of skin and consists of nerves and blood vessels. Yes, its obviously painful and to make a tatoo isn’t less than an act of bravery for many. The point in question is that many of us really wish to have permanent tatoos and many of us may already have had one but rarely anyone of us has ever thought about the side effect of inking at all.

But, we do have a few curious heads called researchers and scientists who are apparently trying to figure out whether this tatoo ink is harmful or not. Now, research findings show that once the ink is delivered by the tatoo artist inside the dermis, it moves to the lymphatic system through the blood stream to the lymph nodes. This is because of the carbon black in the ink which has the ability to break down into nano particles fast and spread through blood. But, sometimes tatoo ink also consists of nickel and chromium additions particularly in organic tatoos. In mice it has also shown to reach the liver. Reaching the liver might take some time but as per dermatologists within minutes of insertion the ink particles reach the lymph nodes.

Now let us understand what happens to the tatoo pigments after the tatoo is done. Some of the ink gets cleared but some is not cleared by the repair cells known as macrophages and remain trapped within the skin cells and showing out through the skin as a tatoo. Generally the ink does not go very far from the point it is injected but some of it does have the ability to travel to the lymph nodes. Research has also shown that many of the individuals with enlarged lymph nodes have been the ones with tatoos for more than a decade.

Well, but it is yet to be proved if tatoo ink is apparently harmful to the body or not. Research is still in progress to say the least.
