sunrise

In this remote region of Russia the sunrise was delayed by several hours

The people of Vyrekhovinsk district in Siberia were upset when they saw that the sun did not arise until 8 am which in normal arises at 4 am a few days earlier, but people in that area had seen such a scene in July last year, so they did not worry much.

Locals say that it has become a strange tradition in their area to delay several hours some morning in August or July.

Although government officials did not provide any explanation for this, meteorologists say it could have caused by a fire in Siberia’s forests. Apparently, when too much carbon monoxide accumulates in the atmosphere it creates a very dark cloud, which is so deep that it hides the sun.

Meteorologists say the amount of carbon monoxide in the area is 7.19mg / m3, which is more than the maximum limit of 5mg / m3 but not enough to cause eclipse conditions.

Alzheimer's

Too much drowsiness can also be a sign of Alzheimer’s

Scientists have discovered that abnormally prolonged sleep and drowsiness can be an important sign of Alzheimer’s because the cells in our brain that keep us awake during the day begin to die when Alzheimer’s begins.

It should be noted that persistent drowsiness can also lead to depression, but it is a timely process, as the sleepiness caused by Alzheimer’s gradually increases and is not controlled by any drug.

Experts at the “Global Brain Health Institute” conducted a detailed examination of the brains of 20 men at the University of California San Francisco. 13 of them had Alzheimer’s disease while the remaining seven did not have the disease.

After examination researchers found that Alzheimer’s disease first attacks the brain cells which are responsible to keep us awake during the day, and because of their activity, we feel refreshed at certain times of the day.
