Dry January Anyone? One of the key benefits of doing the Dry January challenge is better #Sleep . Over half of participants (56%) say their sleep quality was better by the end of the month. Although many people believe alcohol facilitates sleep, alcohol use is actually shown to impair sleep quality and the amount of dream sleep a person gets. This can affect memory and concentration. Alcohol use can also make sleep apnoea worse. It’s no wonder then that giving up alcohol – even temporarily – can benefit sleep quality. And alongside better sleep, 52% of the Dry January participants surveyed reported having more energy, while 50% said they had better overall health. theconversation.com/bette..
