We will all suffer as we get olderinsomnia Sleep will become less and less and of poorer quality. One of the reasons for the phenomenon of insomnia can be: hyperactive neurons This is evident from a study conducted on mice conducted by Luis de Lecea’s team at Stanford University in the United States.

Where are these neurons located? Right in the hypothalamus, an area of ​​the brain and they have the function of producing a protein called orexin or hypocretin. It is a neurotransmitter involved in the regulation of the sleep-wake rhythm. If absent, it causes narcolepsy. This regulation occurs in mice and humans. With age, the number of these neurons decreases. The researchers found that in older mice, neurons tend to be more active during sleep. This discovery could be useful in testing new drugs.

What disrupts sleep? Usually the television is on in the bedroom or the light from the street lamp. These can affect physiology and encourage insomnia. A study conducted by American Northwestern University, on 20 volunteers, provided further evidence. The volunteers had to sleep for two nights or one night in complete darkness and the other in dim light.

The results showed an increase in heart rate with light. On the other hand, a deterioration in blood sugar regulation. It has even been proven by measuring glucose and insulin levels, the hormone that regulates them, in the morning. The team’s hypothesis is that light activates the autonomic nervous system, despite it being asleep.
