Modern research suggests that memories that trigger anxiety or stress can be virtually erased without affecting normal memory. It has been understood that long term memories are stored by increasing the length of neural connections in the brain that are called synapses. In order to strengthen different memories, different proteins are used by the body. During the experiment, researchers were able to delete one memory by blocking a specific protein without harming other memories.
It was also noted during a four year old study on mice that sleep actually helps make some neural connections stronger and larger. On the other hand, the weak connections are destroyed in order to make more space for new memories. This strengthening of neural connections helps increase learning but also increases the brains energy consumption and may cause an overload of its information processing capacity. Sleep is necessary to normalise the overall strength of the neural connections in the brain.
No wonder, health experts suggest having at least 7-8 hours of good sleep each night for an adult. Sleep helps in numerous ways to and contributes greatly to the overall health of a human being. Lack of sleep can cause many health disorders including physical, emotional and mental problems.
