Everyone knows that sleep duration is important, but in reality, many people sacrifice precious sleep time due to work, household chores, hobbies, and other "must-do" and "want-to-do" activities. While the duration of sleep itself is undoubtedly important, for busy modern people, "sleep quality" also requires attention. According to Professor Seiji Nishino of Stanford University, the first 90 minutes after falling asleep are a critical period that determines sleep quality. This period is called the "golden 90 minutes," and it is said that whether or not one can achieve deep sleep during these 90 minutes will affect the overall sleep quality.
Golden 90 minutes - The key time to determine sleep quality
Sleep consists of "non-rapid eye movement (NREM) sleep (deep sleep)" and "rapid eye movement (REM) sleep." The "golden 90 minutes" refers to the first 90 minutes after falling asleep, which is the deepest stage of NREM sleep. During this critical period, it is said that about 70% to 80% of growth hormone is secreted. No matter how long one sleeps, if the quality of sleep in the initial 90 minutes is poor, the entire subsequent sleep cycle will also be affected.
How to improve the sleep quality of the "golden 90 minutes"?
The most important part of sleep is the initial stage of falling asleep, yet many people face difficulties falling asleep. To achieve deeper sleep during the "golden 90 minutes," the key is "controlling body temperature." Before a person enters deep sleep, the temperature of the brain and internal organs decreases. To achieve high-quality sleep, it is necessary to sufficiently lower the internal body temperature. Have you ever noticed that when babies are about to fall asleep, their hands and feet become warm? This is because their core body temperature drops, and heat radiates to the skin surface.
To help lower core body temperature and achieve quality sleep, you can try the following methods:
1. Take a 15-minute hot bath at 40°C 90 minutes before bedtime.
While taking a bath temporarily raises core body temperature, it then "bounces back" with a significant drop. It usually takes about 90 minutes for the temperature to return to its original level after rising. If you can seize this opportunity to go to bed, you will fall asleep more easily.
2. Do not hinder heat dissipation.
When the core body temperature begins to drop, hands and feet become warm to help dissipate heat. If heat dissipation is hindered, the core body temperature cannot completely drop, which may increase difficulty in falling asleep. For example, wearing pajamas with poor breathability or wearing socks while sleeping can hinder heat dissipation and make it difficult to fall asleep.
3. Use appropriate bedding.
Have you ever been woken up by your head feeling stuffy? Common pillow materials such as "polyurethane" or "feathers" can actually hinder heat dissipation. It is recommended to choose a pillow that is breathable and conforms to your head to prevent heat buildup and help you sleep more soundly.

3. The entire pillow is washable, maintaining cleanliness for a long time; warm water at 45-50 degrees can restore fluffiness
The pillow can be washed directly, maintaining hygiene even with long-term use. If the pillow's height or fluffiness feels off, simply rinse it with warm water at approximately 45-50 degrees to restore its fluffy state. Furthermore, this material is less prone to dust mites compared to regular feathers or polyurethane (foam). This allows for comfortable use even in environments with high humidity and temperatures, where dust mites are more likely to thrive.
