From Fortune:

Many drinkers look forward to the tradition of Dry January as a way to reset their relationship with alcohol in the new year. A month-long break from drinking can lead to easier adoption of a low-alcohol lifestyle and multiple health benefits. One of these is a possible improvement in sleep quality, sleep quantity, and general health.

With improved sleep comes improved mood, focus, and performance. Excessive drinking is also associated with possible long-term and irreversible damage to your brain which can lead to a higher risk of dementia. Furthermore, cutting down on drinking can reduce the risk of cancer and other diseases, improve fertility, lead to weight loss, improve mental health, and personal relationships.
