Sleeping and Studying

Sleeping and Studying


Adequate sleep is crucial for memory consolidation, which is the process of transferring new information from short-term memory to long-term memory storage. Here’s why sleep is important for memory:

1. Memory Formation: During sleep, the brain consolidates and organizes newly acquired information, strengthening the connections between neurons. This process helps convert short-term memories into more stable and long-lasting memories.

2. Hippocampus Function: The hippocampus, a brain region involved in memory processing, plays a vital role during sleep. It replays and reinforces the neural pathways related to the information learned during wakefulness, leading to memory consolidation.

3. Memory Stabilization: Sleep helps stabilize memories by protecting them from interference. During sleep, the brain filters out irrelevant information and strengthens important memories, preventing them from being overwritten or forgotten.

4. Learning Enhancement: Sufficient sleep enhances learning and cognitive performance. It improves attention, concentration, and problem-solving abilities, making it easier to acquire new information and store it effectively in memory.

5. REM Sleep and Memory: Rapid Eye Movement (REM) sleep, the stage of sleep associated with vivid dreaming, is particularly important for memory consolidation. REM sleep is linked to emotional memory processing and creative problem-solving, further enhancing memory retention and integration.

6. Sleep Deprivation and Memory Impairment: Insufficient or poor-quality sleep can have detrimental effects on memory. Sleep deprivation disrupts the consolidation process, leading to difficulties in retaining and recalling information. It can also impair attention, focus, and overall cognitive functioning, hindering learning and memory retrieval. See related article.

To optimize memory and cognitive performance, it’s recommended to prioritize regular, quality sleep. Aim for at least 7 hours of sleep per night, establish a consistent sleep schedule, create a conducive sleep environment, and practice good sleep hygiene habits. These practices can help support optimal memory formation and retention. This is why Sleeping and Studying are intertwined 🙂

Mr Khemistry


It is one of the most mysterious concept to the JC chemistry students. This is a concept that is mainly for carbon atom.

Some colleges teach it under chemical bonding, others teach it during introduction to organic chemistry.

No matter where it’s taught, it would be good if you understand what is the main idea here.

Main Gist

Hybridization is simply mixing of atomic orbitals, notably the s and p orbitals for carbon.

1 s + 1 p = two sp hybrid orbitals     => shape: linear (180 bond angle)

1 s + 2 p = three sp^2 hybrid orbitals   => shape: trigonal planar (120 bond angle)

1 s + 3 p = four sp^3 hybrid orbitals   => shape: tetrahedral   (109.5 bond angle)

So there you go, the above is the most important information you’d need.

Do share it with your friends if you found it useful! 🙂
