Generally, eight hours of sound sleep is all one needs to ensure a productive and energetic day. Unfortunately, several people are observed to be suffering from some kind of sleep disorder. Sleep problems are linked to various health conditions, including type-2 diabetes, cholesterol, and cardiovascular diseases. Following a healthy sleep cycle is essential to enhance one’s overall well-being. So, here are 13 tips to follow for a healthy sleep cycle. Set the environment for sleep A conducive sleep environment is a prerequisite for undisturbed sleep throughout the night. For example, studies have shown that the pineal gland present in the brain secretes melatonin when exposed to the dark. Melatonin is the sleep hormone that facilitates drowsiness and sound sleep. So, it is advisable to sleep in a dark, cozy room with dim lights and thick curtains. Avoid sleeping for long hours during the day While taking a quick nap in the afternoon helps one feel refreshed to continue with work, sleeping for long hours during the day can reduce one’s sleep duration at night, affecting one’s sleep cycle. Therefore, it is important to limit one’s siestas by setting an alarm before napping and avoiding snoozing it. Limit caffeine intake Studies have demonstrated that 400 grams of caffeine taken even six hours before bedtime can disrupt one’s sleep considerably.
