Well, experts say pre-bedtime entertainment and work pressure might be major factors affecting people's sleeping quality. The Survey shows that online shopping, chatting and watching online videos are the most popular entrainment before going to bed, on which an average 65 minutes are being spent every day for those surveyed. Experts say these activities might cause long-term excitement, and would in turn, cause sleep difficulties. Pressure at work remains another factor. More than half of those surveyed say they sacrificed sleep hours to complete work assignments. And people working in "high-tension" sectors such as Internet and finance are more likely to suffer from sleep problems. Many say, instead of Taking sleep pills, they are seeking help from technology. For example, smart pillows, which offer Cooling and gentle massage functions. Gadgets and smartphone Apps which track sleep patterns and create relaxing natural sounds. These are a few examples. But while you're trying different products and services, don't forget a key remedy for better sleep is always, simply adjusting your biological clock.
