Pay attention to the temperature and humidity in the dormitory. Generally, the comfortable temperature is 20-23℃ and the relative humidity is 50%-70%. Below 20℃, people will feel cold, above 23℃, people will feel hot, showing that it is difficult to fall asleep and even lift the quilt. Besides, the dormitory is well ventilated.
Pay attention to the influence of bedding on sleep quality, and the bed and quilt should be moderate in hardness. Pillows and cushions play an important role in all bedding.
The pillow should not be too high. Repeated use of cotton cloth pillows in hot summer will cause prickly heat on the head and neck, and the pillows soaked with sweat will not be washed and aired in time, and the smelly sweat will make people dizzy.
In summer, it is advisable to use straw mats finely woven by natural plants, bamboo mats made of porcelain and bamboo unique to China, and cool pillows made of bamboo.
4 nap for many people who can't sleep well at night, a timely nap can be used as compensation. But the best nap time is about 1 hour, not too long.
