So how’s your sleep pattern been. Are you sleeping better, longer, waking up less? We haven’t had a lot of really hot weather yet, but apparently scientists have discovered that very warm temperatures affect how well and how deeply you sleep. The quality seems to be on the downturn if it’s really hot for any prolonged period. A lack of sleep is a risk factor for physical and mental health problems including reduced cognitive performance, hypertension, compromised immune function, depression and more.
