Sleep Management for People With Chronic Conditions

How enough sleep affects blood sugar and blood pressure

Before reading this article

We pay attention to diet and exercise, but it's easy to overlook sleep. However, lack of sleep is one of the main causes of worsening blood sugar and blood pressure.

Summary of key concepts

How sleep affects chronic diseases:

Blood sugar control

Lack of sleep → Increased insulin resistance → Increased blood sugar level
Lack of REM sleep → Imbalance in appetite control hormones → Overeating

Blood pressure

Blood pressure decreases during sleep, but recovery fails when sleep is insufficient.
Increased stress hormones → increased blood pressure

Immunity

Enough sleep → Strengthen immune function → Prevent infection

Tips that actually help

Create good sleep habits

**Regular sleep time**

Go to bed and wake up at the same time every day
Maintain it even on weekends if possible.

**Creating a sleeping environment**

Dark, quiet and cool (18 to 20 degrees)
Comfortable bedding

**Before bed routine**

Turn off your smartphone and TV 1 hour in advance
Shower with warm water
light stretching

**What to avoid**

Caffeine (avoid after 2 p.m.)
Overeating (dinner 2-3 hours before bed)
Drinking alcohol (disrupts deep sleep even if you fall asleep)
Excessive napping (limited to 30 minutes or less)

Common mistakes beginners make

**Viewing smartphone in bed**: Blue light interferes with melatonin secretion
**Sleeping a lot on the weekend**: Disruption of sleep rhythm
**Forcing yourself to lie down when you can't sleep**: If you don't wake up after 15 minutes, get up and do some light activity.

Key Summary

Sleep 7 to 8 hours a day
Maintain a regular sleep schedule
Avoid smartphones and caffeine before going to bed.
Sleep well in a dark environment
