Studies on the cardiovascular changes during sleep have, with one exception, been undertaken in laboratories or hospitals. While all agree that arterial pressure falls, results have differed with regard to changes in heart rate, cardiac output, and total peripheral resistance. The degree of fall in arterial pressure during sleep reported has not been uniform.
Khatri and Freis found that mean arterial pressure fell 7-12% from waking levels in both normotensive and hypertensive patients. While Richardson et al, noted a fall of about 19% in both systolic and diastolic pressure in normotensive people. This was compared with a 12% fall in hypertensive patients. They found that:

Furthermore, in four normotensive subjects who slept at home the fall was even greater, averaging 25% and 30%. The radioimmunoassay used here is specific for the three-ringed cannabinoid nucleus. 9 It does not distinguish between A 9-THC, the most pharmacologically active natural cannabinoid.
Cannabinoid nucleus was used to detect cannabis products in urine. Out of 475 urine tests, 82 came form inpatients in a hospital who were not suspected of taking drugs. Out of this number, all tests came back negative in containing THC.
Studies conducted research on the other chemical compound of the cannabis plant known as CBD. Through these studies, experts found that very specific doses and methods of CBD can reduce resting blood pressure (BP) as well as significantly reduce stress, which may help increase a good nights rest.
If you wish to use CBD or medical cannabis as a form of treatment, make sure you consult your local physician. Also, it is important to check your state and/our countries laws in terms of recreational and medical cannabis.
