Sun Sneezing - Photic Sneeze Reflex

Do you ever noticed people sneezing or sneezed when exposed to bright light like Sun? This is a special reflex that only 25% of people have this reflex. Those people are called Sun sneezers. The phenomenon is called Sun sneezing or Photic sneezing reflex.

The scientific reason behind it?
This is due to the confusion of nerve signals whose path ways are nearer to each other. Those nerves are Trigeminal nerve and Optic nerve. Both are called Carnial nerves which are 12 pairs of nerves arising directly from the brain. These nerves are responsible for sensing information from the sense organs. Whenever we stepout into bright light, the bright light entering the eyes sends a signal to brain via optic nerve which in turn sends signal to eyes to constrict the pupil. This a automatic reflex done to protect the eyes from light and is called pupillary light reflex. The sneeze reflex which works when there is a tickling in the nose, trigeminal nerve is in adjacent with the Optic nerve (responsible for pupil constriction). The trigeminal nerve interacts and also gets the signal from the optic nerve due to the nearness and the sneez reflex is activated. This is how some people sneeze when they are exposed to sunlight.

For most people the trigeminal nerve and optic nerve does not interact. Only for the Sun sneezers it is. The result? Exposure to bright light sends a signal to the brain to constrict the pupils, but the crossed nerve causes a sneeze as well.

Better Mobile Performance and Low Battery Usage

1. Delete Facebook and Messanger Application and use Browser or light. If you think Facebook and Messanger  app is important for your survival, then no other go.

2. Have a simple launcher. Evie launcher, Nova launcher are the light weight launchers with more options. 

3. Disable widgets, clock, battery, weather. Clock and Battery meter is already available in status bar. Why fancy widgets? 

5. Turn off location after using SHAREit, maps.

6. Uncheck adaptive brightness and adjust brightness whenever needed.

7. If you have rooted device you could try Greenify. 

8. Avoid using battery optimisation app, RAM booster. Clear recent tasks often that would be enough. 

Mobile Phone Addiction Controller

Do you use your mobile so often that you feel like you're addicted to it ? If you want to control this addiction, I got a small and easy trick. You need not download any app package, or buy a separate new gadget. There is an inbuilt option which you could use for this purpose. The concept is disabling colours form your mobile phone, that is having black and white screen.

The black and white colour will sure reduce the mobile phone addiction to some extent. Most of the time we check our phone even if there is no notification at all. This is probably our mind is addicted to the fancy colours, the fancy icons in launcher, the widgets in our home screen. But we don't feel that we're addicted, we don't agree either. Most people use to see time from their mobiles even though they wore watches. They only get satisfied when they see time in their mobile. So having a non colour mobile phone could control the addiction for it. You will use it only when needed.

Also some people say black and white colour is safe for eyes, but too much of white light will strain the eyes. Using this bnw colour would be more helpful if you while using mobile during night with low brightness. Some colours are really harmful when using the mobile in dark.

The another advantage battery usage will be reduced. Producing a colourful image would require more power compared to a monochrome image.

So, turn this feature on and give it a try if you really want to control the mobile phone addiction. I used this for a week and felt some changes, infact I hated my mobile phone without colours.
