The bedroom should be a space intended solely for sleeping or having intimate relationships. In this way you can associate it with relaxation and sleep and not with other types of stimuli such as worries, plan tasks, watch TV, etc.
Keep your bedroom clean, tidy, ventilated. Make it a pleasant space. The decoration, the lighting, the type of bed, box spring, mattress, pillow, bedding, etc., are factors to take into account, since they can benefit or harm the quality of sleep.
The degree of humidity, the temperature and even the company can also influence how you sleep.
