Caffeine. Caffeine is the reason. Have your father stop drinking any caffeine products before he goes to bed and he should have a more restful sleep.
Dr. Silviu Pasniciuc
Internal Medicine 27 years experience
Caffeine in black tea can cause tachyarrhythmias or fast and/or irregular heart beats that can wake him up. Not to mention that caffeine can take his sleep away through its stimulant effect.
