Exercise keeps you well but did you know that physical activity may support healthy sleep in middle-aged adults. A study that measured the fitness of more than 8,000 men and women showed that sleep complaints increased as fitness levels declined. The participants performed treadmill tests at four clinics and each test was separated by an average of two to three years.
According to a recent study, the type of food that you eat may influence the quality of your sleep. The 5 day study involved 26 adults between the ages of 30 and 45 who all had normal weights. During the first 4 days, the participants consumed a controlled diet and on the fifth day, they were allowed to choose their own food.
Many people depend on coffee to wake them up and prevent daytime sleepiness. However, according to a recent study, the effect that caffeine has on alertness and performance reduces after 2 days with sleep restriction. Participants in the study were restricted to 5 hours of sleep each night for 5 nights.
