A study published in the Journal, Alcohol: Clinical and Experimental Research showed that alcohol changes the normal rhythms of your sleep, by increasing the amount
of time you spend in deep sleep. Alcohol decreased the amount of time you spend in Rapid Eye Movement (REM) sleep, by disrupting sleep during this stage, which is necessary
for memory, concentration and motor skills.
If you are going to drink alcohol, make sure it is earlier in the evening, not at bedtime.
