 Having trouble sleeping, it might be because your bedroom is also your office or even your gym. If so, the double-duty punching of your bedroom is likely tempering with your sleep at night. That's because it confuses your brain. According to specialists, working in bed could disturb your sleep pattern because your brain no longer associates your bedroom with just sleep. Even worse, it could throw off your productivity and concentration when you do work. So just be mindful if you choose to use your bedroom for multi-use purposes.
